Cleaning base station for a pool, cleaning system for a pool and method for controlling the same

Abstract

This invention discloses a water tank cleaning station, a water tank cleaning system, and a control method thereof. The water tank cleaning station includes a body, a pump body, and a filter structure. The body forms a first inlet, a first outlet, and a first flow channel. When installed on the side wall of a water tank, at least a portion of the first inlet is exposed above the water surface. This invention enables a sufficient height difference at the first inlet, driven by the pump body, to suck up floating debris on the water surface. The water in the first flow channel can generate sufficient water pressure at the first outlet before being discharged outwards. This pushes the water around the first outlet, carrying the floating debris towards the first inlet, thus achieving faster and more complete cleaning of floating debris.

[0002] Pools, including swimming pools, are venues for people to engage in swimming activities or competitions. Most swimming pools are built on land and can be categorized into regular swimming pools and heated swimming pools based on water temperature. To ensure the comfort and safety of people in the pool, it is necessary to clean it periodically. Currently, there are pool cleaning robots that can automatically clean pools, replacing manual labor. However, existing pool cleaning robots can only move on the bottom of the pool using wheels, cleaning dirt from the bottom. They are not very efficient at cleaning floating debris on the surface of the pool, and improvements are urgently needed. Summary of the Invention

[0086] Please see Figures 1 to 8 This invention provides a water tank cleaning base station 1 and a water tank cleaning system thereon. For ease of understanding, in the following embodiments, the water tank cleaning base station 1 and the water tank cleaning system thereon are arranged in pairs in the horizontal, vertical, and vertical directions. The horizontal and vertical directions are two directions that are approximately perpendicular to the horizontal plane that is approximately perpendicular to the vertical direction.

[0087] Specifically, the water tank cleaning base station 1 provided by the present invention is used to be installed on the wall 81 of the water tank 8. The water tank cleaning base station 1 includes a body, a pump body 200 and a filter structure 300. The machine body has a first sewage inlet 110, a first drain outlet 120, and a first flow channel 130 connecting the first sewage inlet 110 and the first drain outlet 120. A pump body 200 is disposed in the first flow channel 130 to drive external water to enter the first flow channel 130 from the first sewage inlet 110 and then discharge it to the outside through the first drain outlet 120. A filter structure 300 is disposed in the first flow channel 130 and divides the first flow channel 130 into a sewage inlet flow channel section near the first sewage inlet 110 and a drainage flow channel section near the first drain outlet 120. The filter structure 300 is used to trap floating dirt carried by the water in the sewage inlet flow channel section. When installed on the side wall of the pool, at least a portion of the first sewage inlet 110 is exposed on the surface of the liquid in the pool.

[0088] In the technical solution provided by this invention, when the robot body is installed on the side wall of the water tank 8, at least the upper end of the first sewage inlet 110 is exposed on the liquid surface of the water tank 8. This allows a sufficient height difference to be formed at the first sewage inlet 110 under the drive of the pump body 200, enabling the suction of floating debris on the liquid surface. Furthermore, since the robot body is located in a basically fixed area within the water tank 8, it facilitates the targeted transfer and cleaning of floating debris on the water tank 8, avoiding the problem of disorderly disturbance of floating debris on the water tank 8 caused by the robot's movement, which would increase the cleaning burden.

[0089] Generally, the water tank cleaning base station 1 includes a body, which includes a housing 100 and some necessary components installed on the housing 100. The housing 100 is installed on the wall of the water tank 8 to be installed. The specific orientation of the wall 81 to be installed is not limited, and it can be, but is not limited to, the bottom wall and / or side wall of the water tank 8. However, it is understood that, since the water tank cleaning base station 1 in this design needs to maintain at least a portion of the first inlet 110 exposed above the water surface when operating the surface cleaning mode to clean floating dirt on the surface of the water tank 8, in order to reduce the design burden on the vertical dimensions of the housing 100, in practical applications, the side wall of the water tank 8 can be set as the wall 81 to be installed, so that the water tank cleaning base station 1 is suspended at the wall 81 to be installed. Specifically, the housing 100 can be provided with a first shell wall located on its longitudinal side and a remaining second shell wall, with the first shell wall installed on the side wall of the water tank.

[0090] The second shell wall can specifically be the longitudinal shell wall on the other side of the housing 100, or the shell walls on both sides in the transverse direction. The first sludge inlet 110 can be located at any of the second shell walls, so that the cleaning process of the first sludge inlet 110 for floating sludge does not interfere with the installation of the housing 100 on the wall 81 to be installed. The first sludge inlet 110 can be located at only one of the aforementioned second shell walls to achieve centralized cleaning of floating sludge on one side. For example, the first sludge inlet 110 can be located at the second shell wall on the longitudinal side of the housing 100. Alternatively, the first sludge inlet 110 can be correspondingly opened at at least two second shell walls to achieve centralized cleaning of floating sludge on at least two sides. For example, the first sludge inlet 110 can be arranged as one elongated section along at least two second shell walls; or at least two first sludge inlets 110 can be correspondingly provided at at least two second shell walls. It should be noted that the opening orientation of the first sewage inlet 110 and / or the first drain outlet 120 corresponds to the extension direction of the central axis of the opening of the first sewage inlet 110 and / or the first drain outlet 120. For a single first sewage inlet 110, taking the first sewage inlet 110 located on the longitudinal side of the housing 100 as an example, the central axis of the first sewage inlet 110 can be substantially parallel to or collinear with the longitudinal direction of the housing 100; of course, the central axis of the first sewage inlet 110 can form a certain angle with the longitudinal direction of the housing 100, for example, the opening of the first sewage inlet 110 can be specifically tilted upwards.

[0091] The machine body generally also includes a cover 150, which is movably disposed on the housing 100 and can be movably opened and closed to cover the first sewage inlet 110. When at least two first sewage inlets 110 are provided as described above, at least two covers 150 can be provided for each first sewage inlet 110. In this case, each cover 150 at each first sewage inlet 110 can be opened and closed in conjunction, or each cover 150 at each first sewage inlet 110 can be opened and closed independently.

[0092] When the water tank is in the liquid surface cleaning mode for floating debris using the cleaning base station 1, the cover 150 at least partially opens the corresponding first sewage inlet 110, and at least a portion of the first sewage inlet 110, or at least one of the first sewage inlets 110, is exposed on the liquid surface of the water tank 8, thereby forming a sufficient liquid level difference between the liquid surface and the sewage inlet channel section connected to the first sewage inlet 110, to help the floating debris enter the sewage inlet channel section more quickly.

[0093] When the water tank cleaning base station 1 is not running the liquid surface cleaning mode for floating dirt, the cover 150 can be set to completely cover the corresponding first sewage inlet 110.

[0094] In view of the above, at least the lower end of the first sewage inlet 110 can be set to a constant position relative to the housing 100. That is, when the housing 100 is fixedly installed on the wall 81 of the pool to be installed in the water tank 8, the lower end of the first sewage inlet 110 remains unchanged relative to the liquid surface, so that the liquid level difference remains unchanged.

[0095] In a further embodiment, at least the lower end of the first sewage inlet 110 can be vertically adjustable relative to the liquid surface of the water tank 8. Based on this, the water tank cleaning base station 1 also includes a first adjustment mechanism for adjusting the vertical position of the lower end of the first sewage inlet 110. This allows the position of the lower end of the first sewage inlet 110 relative to the liquid surface to be adjustable, thereby allowing the liquid level difference formed at the first sewage inlet 110 to be flexibly adjusted.

[0096] For ease of understanding, the following examples will all assume that at least one first sewage inlet 110 is located on the longitudinal side of the housing 100. In order to achieve the purpose of making the first sewage inlet 110 movable and adjustable in the vertical direction along the liquid surface of the water tank 8, at least the lower end of the first sewage inlet 110 is provided.

[0097] In one design, the vertical position of the machine body relative to the wall 81 of the loading tank can be specifically set to be adjustable, and the first adjustment mechanism can drive the vertical translation of the machine body. Based on this:

[0098] In one specific embodiment, the water tank cleaning base station 1 further includes a slide rail 411 and a chute 412. One of the slide rail 411 and the chute 412 is installed on the tank wall 81 to be installed, and the other is installed on the outer wall of the unit. The slide rail 411 extends vertically, and the chute 412 is slidably connected to the slide rail 411 so that the lower end of the first sewage inlet 110 can be adjusted vertically during its sliding process. The chute 412 and the slide rail 411 can be configured in pairs, one or more. When the chute 412 and the slide rail 411 are configured in pairs, each pair of chute 412 and slide rail 411 can be arranged sequentially at intervals along the transverse direction of the housing 100, and specifically, they can be staggered vertically along the housing 100 to improve the stability of the movement of the housing 100 on the tank wall 81 to be installed. Furthermore, the slide rail 411 or slide groove 412 installed on the machine body is offset from the first sewage inlet 110 and / or the first drain outlet 120. In this way, it can be ensured that the arrangement of the slide rail 411 and slide groove 412 will not affect the sewage inlet process of the first sewage inlet 110, nor will it affect the drainage process of the first drain outlet.

[0099] Alternatively, in another specific embodiment, the water tank cleaning base station 1 further includes a rack and a gear. One of the rack and gear is installed on the tank wall 81 to be installed, and the other is installed on the outer wall of the unit. The rack extends vertically, and the gear is slidably connected to the rack so that the lower end of the first sewage inlet 110 can be adjusted vertically during its sliding process. The gear and rack can be configured in pairs, one or more. When the gear and rack are configured in pairs, each pair of gears and racks can be arranged sequentially at intervals along the transverse direction of the housing 100, and specifically, they can be staggered vertically along the housing 100 to improve the stability of the movement of the housing 100 on the tank wall 81 to be installed. Furthermore, the rack or gear installed on the unit is staggered from the first sewage inlet 110 and / or the first drain outlet 120. Of course, the gear and rack can also be replaced with, for example, a combination of a lead screw and nut, without limitation.

[0100] In another design, the position of the machine body relative to the tank wall 81 can be fixed or adjustable. Simultaneously, at least the lower edge of the first inlet 110 can be adjusted vertically relative to the housing 100, and the first adjustment mechanism can drive the vertical translation of at least the lower edge of the first inlet 110. Based on this:

[0101] In one specific embodiment, if the housing further includes a cover 150 as described above, a first through hole may be provided on one longitudinal side wall of the housing 100; and the cover 150 may be positioned below the first through hole and be movable upwards to at least partially cover the opening of the first through hole. The opening of the first through hole not covered by the cover 150 constitutes a first sewage inlet 110, and the upper edge of the cover 150 constitutes the lower edge of the first sewage inlet 110; a first adjusting mechanism is drivenly connected to the cover 150. When the cover 150 moves downwards, the lower edge of the first sewage inlet 110 moves downwards, and simultaneously, the opening cross-sectional area of ​​the first sewage inlet 110 increases; conversely, when the cover 150 moves upwards, the lower edge of the first sewage inlet 110 moves upwards, and simultaneously, the opening cross-sectional area of ​​the first sewage inlet 110 decreases. The movement of the cover 150 relative to the housing 100 is not limited and may include, but is not limited to, translation or flipping.

[0102] Furthermore, when the cover 150 moves vertically relative to the housing 100, to ensure smooth movement of the cover 150, a guide groove extending vertically can be provided on one of the cover 150 and the housing 100, and a guide protrusion that slides or rolls with the guide groove. In a further embodiment, the guide groove may include a first groove segment, a second groove segment, and a third groove segment connected sequentially from bottom to top. At least the depth of the second groove segment can be set to gradually decrease from bottom to top, so that when the guide protrusion moves with the second groove segment, it can move upward while moving longitudinally away from the side wall where the first through hole is located. This helps to maximize the total opening cross-sectional area of ​​the first sewage inlet 110 while the lower end of the first sewage inlet 110 moves upward along with the cover 150, thus avoiding affecting the sewage flow rate at the first sewage inlet 110. In addition, the depth of at least the third groove segment can be set to gradually increase from bottom to top, so that when the guide protrusion is in active cooperation with the third groove segment, it can move upward and approach the side wall where the first through hole is located in the longitudinal direction. When the cover 150 completely covers the first through hole, it ensures that the cover 150 is also completely in contact with the side wall where the first through hole is located in the longitudinal direction, thereby enhancing the sealing effect of the cover 150 on the first sewage inlet 110.

[0103] To improve the efficiency of allowing floating debris to enter the first flow channel 130, in one embodiment, the machine body further includes a rotating module disposed within the first flow channel 130 and adjacent to the first inlet 110. The rotating module includes rotatable blades 620 and a power component drivenly connected to the blades 620. During the rotatable process of the blades 620, floating debris at the first inlet 110 is driven into the first flow channel 130. The blades 620 can be disposed independently, or further, the rotating module also includes a roller 610, which is rotatably mounted on the housing 100 about a laterally extending axis, and the blades 620 protrude radially outward from the roller 610.

[0104] Therefore, in another specific embodiment where at least the lower edge of the first sewage inlet 110 can move up and down, at least the roller shaft 610 in the aforementioned rotating module is movably arranged in the vertical direction, so that the roller shaft 610 can directly constitute the aforementioned cover 150. At this time, when the roller shaft 610 moves downward, it is equivalent to the lower edge of the first sewage inlet 110 moving downward, and at the same time, the opening cross-sectional area of ​​the first sewage inlet 110 increases; conversely, when the roller shaft 610 moves upward, it is equivalent to the lower edge of the first sewage inlet 110 moving upward, and at the same time, the opening cross-sectional area of ​​the first sewage inlet 110 decreases. Since the blades 620 at the roller 610 move synchronously with the roller 610, the relative position between the blades 620 and the first sewage inlet 110 defined by the roller 610 and the first through hole remains basically constant, no matter where the roller 610 moves relative to the housing 100. This ensures that the driving effect of the blades 620 on the floating sewage passing through the first sewage inlet 110 remains basically consistent during the tumbling process.

[0105] The design of the first adjustment mechanism in any of the above embodiments is not limited, and can be, but is not limited to, a driver such as a motor or a linear cylinder. Alternatively, it can be a combination of a driver and a transmission assembly. Or it can be based on, for example, a buoyancy sensor or a floating mechanism. It can also be combined with, for example, a liquid level sensor or a water pressure sensor.

[0106] When the driver is a motor or similar device providing rotary output, the transmission assembly can convert the rotary output of the motor into a linear output of the housing 100 / cover 150 / roller 610. During the conversion process, adjustments such as speed and direction can be made as needed, specifically, but not limited to, a rack and pinion mechanism or a lead screw and nut mechanism. Alternatively, when the driver is a linear cylinder or similar device providing linear output, the transmission assembly can convert the linear output of the linear cylinder into a rotary output of the linear output of the housing 100 / cover 150 / roller 610. During the conversion process, adjustments such as speed and direction can be made as needed. The first adjustment mechanism can also be, for example, a float 420. The float 420 is connected to the housing 100 / cover 150 / roller 610. When the average density of the float 420 remains constant, the float 420 can cause the housing 100 / cover 150 / roller 610 to float according to the liquid in the current water tank 8, so that the position of the lower edge of the first sewage inlet 110 remains constant. However, when the average density of the float 420 is adjustable, the float 420 can drive the housing 100 / cover 150 / roller 610 to move up and down within the current water tank 8, so that the position of the lower edge of the first sewage inlet 110 can be flexibly adjusted.

[0107] In another specific embodiment, when a first through hole is provided on one longitudinal side wall of the housing 100 as described above, the housing also includes a mounting frame and an elastic connector. The mounting frame is made of float material 420 and is movably mounted within the first through hole at least vertically, with the frame area defining a first sewage inlet 110. The elastic connector is sealed between the wall of the first through hole and the outer wall of the mounting frame. The first adjustment mechanism includes a counterweight connected to the mounting frame, and the weight of the counterweight is adjustable.

[0108] Specifically, the mounting frame can be plate-shaped or rod-shaped and only located at the lower edge of the first through hole; the elastic connector connects the mounting frame and the lower edge of the first through hole. Alternatively, the mounting frame can be L-shaped, U-shaped, or U-shaped and extend to any one or at least two edges of the first through hole other than the lower edge; the elastic connector is adapted to the shape of the mounting frame. The mounting frame is made of float 420 material, which is any material with a density less than that of the liquid in the pool 8 that can float on the liquid surface or be suspended in the pool 8, including but not limited to foam, wood, and airbags. The purpose of the elastic connector is twofold: first, to seal the connection between the mounting frame and the edge of the corresponding first through hole; and second, to allow sufficient freedom of movement for the vertical movement of the mounting frame. Therefore, the elasticity of the elastic connector can be directly defined by the elastic material. Examples of elastic materials include rubber and silicone. Alternatively, the elasticity of the elastic connector can be defined by a proprietary structure. Examples of proprietary structures include foldable and unfoldable multi-layered folding structures.

[0109] The floating effect of the mounting frame relative to the liquid can be set to be fixed, so that when the housing 100 is installed on the wall 81 of the pool to be installed, the mounting frame directly adapts to the liquid in the pool 8 and floats on the liquid surface, forming a first sewage inlet 110 with a basically constant opening cross-sectional area. Alternatively, the floating effect of the mounting frame relative to the liquid can be set to be adjustable, specifically through the aforementioned counterweight. When the counterweight is connected and fixed to the mounting frame as a whole, by changing its cavity size, overall volume, shape, etc., the average density of the counterweight and the mounting frame as a whole can be changed, ultimately achieving the purpose of adjusting the vertical position of the lower edge of the first sewage inlet 110.

[0110] Based on one or more of the above embodiments, the first drain outlet 120 can be specifically set on one or both sides of the transverse side of the housing 100. Specifically, one or at least two first drain outlets 120 located on the same transverse side of the housing 100 can be provided. It can be understood that when the first sewage inlet 110 is set on one longitudinal side of the housing 100, it mainly focuses on cleaning floating debris located on the longitudinal front side of the housing 100. The areas on both sides of the housing 100, especially the area located on the longitudinal rear side of the first sewage inlet 110, constitute a cleaning blind zone for the first sewage inlet 110. Floating debris in this cleaning blind zone is not easily cleaned directly by the first sewage inlet 110. This design, by setting the first drain outlet 120 in this cleaning blind zone, utilizes the water flow discharged from the first drain outlet 120 to carry the floating debris in the cleaning blind zone to the first sewage inlet 110.

[0111] Generally, the included angle D between the orientations of the first drain outlet 120 and the first sewage inlet 110 is not limited, as long as the purpose of the above-mentioned water flow discharged from the first drain outlet 120 is achieved, which can carry the floating dirt in the cleaning blind area to the first sewage inlet 110, is within the protection scope of this design.

[0112] Furthermore, in one embodiment, the angle D between the orientations of the first sewage inlet 110 and the first drain outlet 120 can be set to be less than 90°. By utilizing the pressure of the water flow discharged outward from the first drain outlet 120, the floating dirt in the cleaning blind spot can be driven to gradually move towards the longitudinal front side of the first sewage inlet 110, thereby making it easier for the floating dirt to be sucked up by the first sewage inlet 110.

[0113] Alternatively, in one embodiment, when installing the machine body onto the wall of the tank to be cleaned, the wall can be specifically selected such that a reflective surface is formed on the side of the first drain outlet 120 away from the first inlet outlet 110. The reflective surface ensures that even when the angle D between the orientations of the first inlet outlet 110 and the first drain outlet 120 is not less than 90°, causing the water discharged from the first drain outlet 120 to flow away from the first inlet outlet 110, the reflective surface can reverse the water flow, causing it to flow towards the first inlet outlet 110. This achieves the purpose of gradually moving the floating debris in the cleaning blind spot towards the longitudinal front side of the first inlet outlet 110. It can be understood that when the first inlet outlet 110 is located on the longitudinal side of the housing 100, and the first drain outlet 120 is located on at least one transverse side of the housing 100, the other longitudinal side of the housing 100 can be installed on the side wall of the pool. In this case, the side wall of the pool both constitutes the aforementioned wall to be cleaned and directly defines the reflective surface.

[0114] Alternatively, in one embodiment, the water tank floating debris cleaning base station 1 further includes a reflector plate, which protrudes from the first drain outlet 120 on the side away from the first sewage inlet 110, and the surface of the reflector plate constitutes a reflective surface. Specifically, when the first sewage inlet 110 is located on the longitudinal side of the housing 100 as described above, and the first drain outlet 120 is located on at least one transverse side of the housing 100, the reflector plate can extend transversely and protrude from the first drain outlet 120 on the longitudinal side away from the first sewage inlet 110.

[0115] It should be noted that, for ease of understanding, in the following embodiments, the angle D between the orientations of the first sewage inlet 110 and the first drainage outlet 120 is less than 90° as an example.

[0116] In view of the above, in order to facilitate the smooth entry of floating debris into the first flow channel 130, the opening orientation of the first inlet 110 is generally set to remain constant. The opening orientation of the first outlet 120 can be set to remain fixed or adjustable as needed. Specifically, when the opening orientation of the first outlet 120 is adjustable, the water tank cleaning base station 1 may further include a second adjustment mechanism. This second adjustment mechanism can be used to adjust the opening orientation of the first outlet 120, thereby correspondingly adjusting the flow direction of the water discharged through the first outlet 120, and ultimately controlling the flow direction of the floating debris located in the aforementioned cleaning blind zone, carried by the water discharged from the first outlet 120. This ensures that the floating debris in each part of the cleaning blind zone can flow along a relatively reasonable path towards the first inlet 110.

[0117] Furthermore, the cross-sectional area of ​​the first drain outlet 120 can be set to be constant or adjustable according to actual needs. Specifically, when the cross-sectional area of ​​the first drain outlet 120 is adjustable, the second adjustment mechanism can also be used to adjust the cross-sectional area of ​​the first drain outlet 120, correspondingly adjusting the flow rate of water discharged through the first drain outlet 120, and consequently adjusting the water pressure. When the water pressure is higher, it can cause floating debris in the aforementioned blind cleaning area to flow more quickly towards the longitudinal front of the first sewage inlet 110; conversely, when the water pressure is lower, it can cause floating debris in the aforementioned blind cleaning area to flow more slowly towards the longitudinal front of the first sewage inlet 110.

[0118] Furthermore, the flow rate of the water discharged through the first drain outlet 120 can be set to a constant value or adjustable as needed. Specifically, when the flow rate of the water discharged through the first drain outlet 120 is adjustable, the second adjustment mechanism can also be used to adjust the flow rate of the water discharged through the first drain outlet 120. It should be noted that the second adjustment mechanism can be configured to directly adjust the flow rate of the water discharged through the first drain outlet 120, or it can be configured to indirectly adjust the flow rate of the water discharged through the first drain outlet 120 by adjusting the operating parameters of the pump body 200. When the flow rate of the water discharged through the first drain outlet 120 is adjustable, the pressure of the water discharged through the first drain outlet 120 is adjusted accordingly. Similarly, when the water pressure is high, the floating debris in the aforementioned blind cleaning area can be moved more quickly towards the longitudinal front of the first sewage inlet 110; conversely, when the water pressure is low, the floating debris in the aforementioned blind cleaning area can be moved more slowly towards the longitudinal front of the first sewage inlet 110.

[0119] As can be understood from the above, when at least two first drain outlets 120 are provided, each first drain outlet 120 can be located on both sides of the first sewage inlet 110, so that each first drain outlet 120 can respectively act on the cleaning blind spots on both sides of the first sewage inlet 110. When more than two first drain outlets 120 are provided, then at least two first drain outlets 120 may be arranged on the same side of the first sewage inlet 110.

[0120] Specifically, the first drain outlets 120 located on the same transverse side of the first sewage inlet 110 can be arranged sequentially at intervals along the longitudinal direction:

[0121] In one embodiment, the second adjustment mechanism can be used to adjust the first drain outlets 120 located on the same side to gradually deflect towards the side where the first sewage inlet 110 is located. That is, the angle between the orientation of the first drain outlet 120 furthest from the first sewage inlet 110 along the longitudinal direction is relatively the largest; the angle between the orientation of the second furthest from the first sewage inlet 110 along the longitudinal direction is relatively the second largest... the angle between the orientation of the second furthest from the first sewage inlet 110 along the longitudinal direction is relatively the second smallest; and the angle between the orientation of the first drain outlet 120 closest to the first sewage inlet 110 along the longitudinal direction is relatively the smallest.

[0122] And / or in one embodiment, the second adjustment mechanism is used to adjust the opening cross-sectional area of ​​each of the first drain outlets 120 located on the same side to gradually increase in the direction away from the first sewage inlet 110. That is, the opening cross-sectional area of ​​the first drain outlet 120 furthest from the first sewage inlet 110 along the longitudinal direction is relatively the largest; the opening cross-sectional area of ​​the first drain outlet 120 furthest from the first sewage inlet 110 along the longitudinal direction is the second largest... the opening cross-sectional area of ​​the first drain outlet 120 closest to the first sewage inlet 110 along the longitudinal direction is the second smallest; and the opening cross-sectional area of ​​the first drain outlet 120 closest to the first sewage inlet 110 along the longitudinal direction is relatively the smallest.

[0123] And / or in one embodiment, the second adjusting mechanism is used to adjust the flow velocity of each of the first drain outlets 120 located on the same side to gradually increase in the direction away from the first sewage inlet 110. That is, the flow velocity of the first drain outlet 120 furthest from the first sewage inlet 110 along the longitudinal direction is relatively the largest; the flow velocity of the first drain outlet 120 furthest from the first sewage inlet 110 along the longitudinal direction is the second largest... the flow velocity of the first drain outlet 120 closest to the first sewage inlet 110 along the longitudinal direction is the second smallest; and the flow velocity of the first drain outlet 120 closest to the first sewage inlet 110 along the longitudinal direction is relatively the smallest.

[0124] In this way, the water discharged from each of the first drain outlets 120 on the same transverse side of the first sewage inlet 110 can radially and almost completely cover the entire cleaning blind area on the same side. Moreover, the further away the water is from the first sewage inlet 110, the greater the flow rate and / or water pressure, which can gradually push the floating debris furthest from the first sewage inlet 110 toward the first sewage inlet 110. This helps the floating debris to enter the first sewage inlet 110 in an orderly and batch-wise manner, which can not only improve cleaning efficiency, but also avoid blockage at the first sewage inlet 110 to a certain extent.

[0125] Furthermore, specifically, the first drain outlets 120 located on the same horizontal side of the first sewage inlet 110 can also be arranged sequentially at intervals in the vertical direction:

[0126] In one embodiment, the second adjustment mechanism can be used to adjust the gradual deflection of each of the first drain outlets 120 located on the same side from bottom to top. That is, the opening of the lowest first drain outlet 120 faces downward and has the largest angle with the horizontal plane; the opening of the second lowest first drain outlet 120 faces downward and has the second largest angle with the horizontal plane... the opening of the second highest first drain outlet 120 faces slightly downward and has the second smallest angle with the horizontal plane; the opening of the highest first drain outlet 120 is basically flush with the horizontal plane. In this way, the water flow discharged from the lowest first drain outlet 120 can lift the sediment or suspended sediment to the top, and then gradually carry it to float on the liquid surface. Finally, it is carried by the water flow discharged from the highest first drain outlet 120 towards the first sewage inlet 110, where it is sucked up and cleaned.

[0127] Of course, the opening cross-sectional area and / or flow velocity of the first drain outlet 120 can also be adjusted according to actual needs, which will not be elaborated here. Moreover, according to actual needs, in a specific application, the first drain outlets 120 located on the same side of the first sewage inlet 110 can be arranged sequentially at intervals along the longitudinal direction or sequentially along the vertical direction.

[0128] It should be noted that the specific structural composition of the second regulating mechanism to achieve the above purpose can be specifically set according to the specific structural composition of the first drain outlet 120:

[0129] For example, in one embodiment, the transverse shell wall of the housing 100 is provided with the first drain outlet 120. The first drain outlet 120 has a proximal edge along the longitudinal direction near the first sewage inlet 110 and a distal edge away from the first sewage inlet 110. The housing also includes a guide plate 510, which protrudes from the outer side of the housing 100 and has one end edge rotatably connected to the distal edge, so as to have a first stroke that drives the other end edge to flip in the direction near the proximal edge and a second stroke that flips in the direction away from the proximal edge. The second adjustment mechanism is drivenly connected to the guide plate 510. The guide plate 510 can be provided as one, and one end edge of the guide plate 510 is rotatably connected to the distal edge of the first drain outlet 120; or the guide plate 510 can be provided as two, and one end edge of the guide plate 510 is rotatably connected to the distal edge of the first drain outlet 120, while one end edge of the other guide plate 510 is rotatably connected to the proximal edge of the first drain outlet 120, and the two guide plates 510 rotate substantially synchronously. During its rotation, the guide plate 510 can guide the water flow discharged through the first drain outlet 120 to the desired direction, thereby changing the direction of the water flow, which is equivalent to changing the orientation of the first drain outlet 120.

[0130] It is understandable that, since the first sewage inlet 110 is located on the longitudinal front side of the first drain outlet 120, when the guide plate 510 makes its first stroke, it can bring the floating dirt in the cleaning blind area to the first sewage inlet 110. However, conversely, when the guide plate 510 makes its second stroke, it may carry away the floating dirt around the first sewage inlet 110. Therefore, in a practical application, if the water tank uses the cleaning base station 1 to operate in the liquid surface cleaning mode, the guide plate 510 can be specifically set to make only one first stroke at a preset speed under the drive of the second adjustment mechanism and not make a second stroke. This ensures that in the entire liquid surface cleaning mode, the guide plate 510 will not make a second stroke and carry away the floating dirt in the opposite direction, thus affecting the cleaning effect of the floating dirt.

[0131] In another practical application, if the water tank is operating in the liquid level cleaning mode using the cleaning base station 1, and the second adjustment mechanism needs to drive the guide plate 510 to repeatedly switch between the first and second strokes:

[0132] In one design, a guide plate 510 may be rotatably mounted on the housing 100 about an axis extending along the proximal or distal edge of the first drain outlet 120. The guide plate 510 rotates for a first stroke on the outside of the housing 100 and for a second stroke on the inside of the housing 100 (e.g., at the drain channel section), so that the guide plate 510 does not carry away the floating dirt at the first inlet 110 in the opposite direction during the second stroke.

[0133] Alternatively, in one design, the guide plate 510 has a clearance hole 511 extending along its thickness direction; the machine body also includes a one-way opening and closing structure 512, which is located at the clearance hole 511. The clearance hole 511 is closed during the first stroke of the guide plate 510 and opened during the second stroke. Thus, during the first stroke, the one-way opening and closing structure 512 closes the clearance hole 511, allowing the guide plate 510 to form sufficient contact surface with the water in the pool 8, generating sufficient water pressure to move floating debris towards the first inlet 110. During the second stroke, the one-way opening structure 512 opens the clearance hole 511, reducing the contact area between the guide plate 510 and the water in the pool 8, generating less water pressure to move floating debris away from the first inlet 110, thereby significantly reducing the adverse effects on the suction of floating debris from the first inlet 110.

[0134] Specifically, one or at least two clearance holes 511 may be formed on the guide plate 510. When one clearance hole 511 is formed, the opening cross-sectional area of ​​the clearance hole 511 is at least sufficient to achieve the above-mentioned purpose. When at least two clearance holes 511 are formed, the clearance holes 511 may be distributed on the guide plate 510.

[0135] The specific form of the one-way opening and closing structure 512 is not limited. For example, in one embodiment, the clearance hole 511 can be set as a conical hole, and the diameter of the conical hole gradually decreases in the direction away from the first sewage inlet 110. The one-way opening and closing structure 512 is arranged in a block shape at the clearance hole 511. When the guide plate 510 performs the first stroke, the one-way opening and closing structure 512 is driven to cooperate with the smaller diameter section of the clearance hole 511 to achieve the purpose of blocking the clearance hole 511. Conversely, when the guide plate 510 performs the second stroke, the one-way opening and closing structure 512 is driven to cooperate with the larger diameter section of the clearance hole 511, maintaining a distance and forming a gap with the larger diameter section to achieve the purpose of opening the clearance hole 511.

[0136] Alternatively, in one embodiment, the one-way opening and closing structure 512 is plate-shaped and disposed on the side of the guide plate 510 near the proximal edge, and is movable in the direction of approaching and moving away from the guide plate 510; wherein, the plate area of ​​the one-way opening and closing structure 512 is larger than the radial cross-sectional area of ​​the clearance hole 511. Thus, when the guide plate 510 performs its first stroke, the one-way opening and closing structure 512 is driven to conform to the guide plate 510 because its plate surface is larger than the clearance hole 511, thereby covering the clearance hole 511; conversely, when the guide plate 510 performs its second stroke, the one-way opening and closing structure 512 is driven to flip away from the guide plate 510, thereby opening the clearance hole 511.

[0137] The aforementioned one-way opening and closing structure 512 requires no additional power mechanism. It achieves switching between open and closed states solely through the relative force between the water flow in the pool 8 and the guide plate 510. Alternatively, in other applications, a power mechanism can be added to the one-way opening and closing structure 512, which can intelligently and automatically drive and control the structure.

[0138] Given the above embodiments, the design of the second adjustment mechanism is not limited and can be, but is not limited to, a driver such as a motor or a linear cylinder. Alternatively, it can be a combination of a driver and a transmission assembly. When the driver is a motor or similar device providing rotary output, the transmission assembly can convert the motor's rotary output into the rotational output of the guide plate 510, and adjust the speed and direction as needed during the conversion process. Specifically, it can be, but is not limited to, a gear set or a worm gear mechanism. Alternatively, when the driver is a linear cylinder or similar device providing linear output, the transmission assembly can convert the linear output of the linear cylinder into the rotary output of the guide plate 510, and adjust the speed and direction as needed during the conversion process. Specifically, it can be, but is not limited to, a rack and pinion mechanism or a lead screw and nut mechanism.

[0139] In another embodiment, the housing 100 has a first sewage inlet 110 on one longitudinal side of its housing wall, and at least one second through hole 140 on each of its two transverse side housing walls. The housing also includes at least two connecting pipes 520, each connecting pipe 520 correspondingly connecting to each second through hole 140 and a drainage channel section. The second through hole 140 or the pipe opening of the connecting pipe 520 near the second through hole 140 constitutes a first drain outlet 120.

[0140] The second through hole 140 allows for the limiting installation of the connecting pipe 520. Specifically, the opening of the connecting pipe 520 can be substantially flush with the opening of the second through hole 140, or the opening of the connecting pipe 520 can be located inside the opening of the second through hole 140, or the opening of the connecting pipe 520 can extend outside the opening of the second through hole 140.

[0141] The opening of the connecting pipe 520 can directly form the first drain outlet 120. In this case, the opening of the connecting pipe 520 can be a flat opening or an oblique opening, which helps to maximize the opening cross-sectional area of ​​the first drain outlet 120 based on the limited diameter of the connecting pipe 520.

[0142] Based on the above, the machine body also includes an adjustable nozzle 530, which is connected to the inlet of the connecting pipe 520, so that the inlet of the connecting pipe 520 indirectly forms the first drain outlet 120 through the adjustable nozzle 530. The opening orientation and / or opening cross-sectional area of ​​the adjustable nozzle 530 can be adjusted, and it also constitutes a second adjustment mechanism. Since the connecting pipe 520 is connected to the drain channel section, the pump body 200 also acts on the water flow flowing at the connecting pipe 520, so that the flow rate of the water at the connecting pipe 520 can be adjusted. At this time, if the pump body 200 can independently achieve the adjustment of the working parameters, then the pump body 200 also constitutes the second adjustment mechanism; or if the pump body 200 needs to use an external control device to achieve the adjustment of the working parameters, then the second adjustment mechanism can serve as a control device. Furthermore, the second adjustment mechanism may also include an angle recognition device, which is used to identify the water outlet angle of the adjustable nozzle 530 to facilitate better control of the opening orientation of the first drain outlet 120. Angle recognition devices can be, but are not limited to, Hall sensors, collision-triggered limit switches, etc.

[0143] Alternatively, based on the above embodiments, at least a portion of each connecting pipe 520 is further configured to bend radially; the second adjusting mechanism is driven to connect to at least one side wall of the connecting pipe 520 to drive the connecting pipe 520 to bend radially. When the connecting pipe 520 bends laterally, the opening orientation of its pipe opening, i.e., the opening of the first drain outlet 120, can be changed.

[0144] The design of the second adjustment mechanism for driving the connecting tube 520 to bend laterally is not limited. For example, the second adjustment mechanism may include a traction member and a winding device. One end of the traction member is connected to the side wall of the connecting tube 520, and the other end is movably wound around the winding device. The winding device has a winding state and a release state under the drive of a driver such as a motor. When in the winding state, the traction member can pull the side wall of the connecting tube 520 to bend the connecting tube 520 to the corresponding side; conversely, when in the release state, the traction member releases the pull on the side wall of the connecting tube 520, so that the connecting tube 520 returns to its original position.

[0145] It should be noted that the aforementioned connecting pipe 520 can be configured to be flexible along one longitudinal side, or it can be configured to be flexible along both longitudinal sides respectively. And / or, the aforementioned connecting pipe 520 can be configured to be flexible upwards or downwards.

[0146] Furthermore, in one embodiment, the machine body also includes at least two regulating valves, each corresponding to one of the connecting pipes 520, to independently adjust the opening degree at its location within each connecting pipe 520. The regulating valves constitute a second regulating mechanism, which can adjust the opening degree at its location within the connecting pipe 520, ultimately helping to adjust the opening cross-sectional area of ​​the first drain outlet 120.

[0147] Furthermore, it can be understood that when the filter structure 300 is located at the first flow channel 130, if the filter structure 300 is plate-shaped, it can be radially separated along the first flow channel 130, thereby dividing the first flow channel 130 into a sewage inlet section and a drainage section. If the filter structure 300 defines a separate filter chamber, for example, if the filter structure 300 is frame-shaped, then that filter chamber directly constitutes the sewage inlet section.

[0148] The aforementioned first flow channel 130 and filter structure 300 can be configured as one or more. Alternatively, the inlet flow channel section and / or outlet flow channel section in the same first flow channel 130 can be configured as one or at least two according to actual needs.

[0149] The inlet flow channel section can be located at least partially below the first inlet 110, so that when floating debris is carried into the inlet flow channel section, it will remain below the first inlet 110 under the action of water pressure and gravity. This ensures that when the pump body 200 stops running, the floating debris trapped in the inlet flow channel section will not accumulate at the first inlet 110 or leak outward from the first inlet 110.

[0150] And / or, the flow channel section connecting the sewage inlet section to the first sewage inlet 110 is narrowed. That is, the radial cross-sectional area of ​​the flow channel section near the first sewage inlet 110 is smaller than the opening cross-sectional area of ​​the first sewage inlet 110 and the radial cross-sectional area of ​​the remaining flow channel section, so that floating sewage can enter the sewage inlet section more smoothly through the first sewage inlet 110, but is easily blocked and limited by the narrowed section when flowing from the sewage inlet section to the first sewage inlet 110.

[0151] In view of the above, in one embodiment, at least a portion of the blades 620 in the rotating module is hollowed out along its thickness direction, equivalent to forming a screen. Thus, when the blades 620 are rotated by the roller 610, they can primarily carry floating debris more quickly into the first flow channel 130, reducing disturbance to the water flow to a certain extent. And / or in one embodiment, multiple blades 620 are sequentially arranged along the circumference of the roller 610, and each blade 620 can extend elongatedly along the axial direction of the roller 610, specifically, it can be straight or spiral. When multiple blades 620 are sequentially arranged along the circumference of the roller 610, floating debris can be continuously grasped and carried away, improving the cleaning efficiency of floating debris. And / or in one embodiment, at least the free section of the blades 620 is made of an elastic deformable material. The elastic deformable material can be, but is not limited to, rubber. When at least the free section of the blade 620 is made of an elastically deformable material, it may elongate under centrifugal force during the rotation of the blade 620, increasing the contact area between the blade 620 and floating debris. Furthermore, by making the free section of the blade 620 into an elastically deformable material, even if a collision occurs between the free section of the blade 620 and surrounding components, it will be a flexible collision, avoiding structural damage.

[0152] Of course, the necessary components installed at the housing 100 mentioned above may include, but are not limited to, one or more of the following: power supply module, control device, detection module, human-machine interaction module, etc.

[0153] The power supply module can adopt any power supply form, including but not limited to wireless charging modules, solar charging modules, and energy storage modules, which helps to save electricity and protect the environment, and can support the long-term use of the water tank cleaning base station 1. The wireless charging module can be integrated between the water tank cleaning base station 1 and an external power source, or between the cleaning robot 7 and the water tank cleaning base station 1, reducing manual operation and increasing ease of use.

[0154] The detection module is located within the machine body and is used to detect environmental parameters at the machine's location. This allows the control device to control the associated first and / or second adjustment mechanisms based on these environmental parameters. Specifically, the detection module may include a water quality detection module, a temperature detection module, and a water quality adjustment module. The water quality detection module and the water quality adjustment module can be used in conjunction. The water quality detection module detects the parameters of the water in the current water tank 8. Then, based on the detected parameter values, when the control device determines that the water in the water tank 8 does not meet the standards, it controls the corresponding water quality adjustment module to adjust the water quality, for example, by releasing a water quality adjustment reagent or using ultraviolet light for sterilization.

[0155] The human-machine interface module includes an input module. The input module is located on the main body and is used to input numerical values, which are then used by the control device to control the operation of the associated first and / or second adjustment mechanisms. The input module can be configured as needed, for example, to input a voice recognition module and a display control module; at least one of these can be selected. This establishes communication and interaction between the user and the water tank cleaning base station 1. For example, the user can trigger commands via voice or touch to interact with the water tank cleaning base station 1; the user can also input specific values ​​of relevant parameters based on the input module. Of course, the water tank cleaning base station 1 can also achieve preset abnormal alarms through the human-machine interface module, or the user can view relevant information about the water tank 8 in real time via a display screen, making the use of the water tank cleaning base station 1 more intelligent and user-friendly.

[0156] Furthermore, based on one or more of the above embodiments, the pool cleaning system, in addition to the pool cleaning base station 1, also includes a cleaning robot 7. The cleaning robot 7 includes a housing forming a second inlet 710, a second outlet 720, and a second flow channel 730 connecting the second inlet 710 and the second outlet 720. The cleaning robot 7 also includes a dust box 740, which is equivalent to the aforementioned filter structure 300, and is capable of trapping solid waste entering the second flow channel 730 through the second inlet 710 within the dust box 740.

[0157] The cleaning robot 7 and the pool cleaning base station 1 have at least two states: a separated state and a docked state. In the separated state, the pool cleaning robot 7 can work independently, for example, moving within the pool 8 along a preset trajectory and cleaning debris such as from the pool walls during its movement. In the docked state, the pool cleaning base station 1 can perform operations on the cleaning robot 7, such as charging and automatically emptying the dustbin 740. The cleaning robot 7 can flexibly switch between the separated and docked states under the control of the control device.

[0158] Therefore, in a further embodiment, the cleaning robot 7 also includes a docking section, and the cleaning base station 1 for the water tank includes a connecting section. When in a separated state, the connecting section and the docking section are separated; conversely, when in a docking state, the connecting section and the docking section are connected. There are various specific designs for the connecting section and the docking section, and they can be configured as structures distinct from the first flow channel 130 and the second flow channel 730. Alternatively, they can be directly composed of the first flow channel 130 and the second flow channel 730.

[0159] It should be noted that, in order to ensure that the above-mentioned water tank cleaning base station 1 can better operate in the liquid surface cleaning mode for floating dirt, in a further embodiment, the first sewage inlet 110 can be staggered from the cleaning robot 7 when the cleaning robot 7 and the water tank cleaning base station 1 are docked. This ensures that no part of the cleaning robot 7 will obstruct the first sewage inlet 110 and / or the first drain outlet 120, thereby ensuring the functional independence and efficiency of the water tank cleaning base station 1 when operating in the liquid surface cleaning mode.

[0160] Specifically, when the cleaning base station 1 for the water tank is installed to the side wall of the water tank, at least a portion of the first sewage inlet 110 is exposed above the liquid surface of the water tank and is located above the connection portion. This ensures that the cleaning robot 7 does not obstruct the first sewage inlet 110. Furthermore, when the cleaning robot 7 docks with the cleaning base station 1 for the water tank, the cleaning robot 7 is positioned below the liquid surface of the water tank, so that the cleaning robot 7 also does not obstruct the path of floating debris entering the first sewage inlet 110.

[0161] In the above embodiments, the cleaning base station 1 in the pool is generally used alone to remove floating debris from the liquid surface. Based on this, in a further embodiment, the cleaning base station 1 in the pool can take the lead, while the cleaning robot 7 assists in cleaning the floating debris from the liquid surface.

[0162] Specifically, the pool cleaning system includes a pool cleaning base station 1, a cleaning robot 7, a power unit, and a control device. The pool cleaning base station is provided with a first flow channel; the cleaning robot 1 is provided with a second flow channel 130; the power unit can selectively act on the first flow channel 130 and / or the second flow channel 730; the control device is electrically connected to the pool cleaning base station 1, the cleaning robot 7, and the power unit respectively, so that under the control of the control device, the pool cleaning system has a first liquid surface cleaning mode when the upstream end of the first flow channel 130 is in communication with the liquid surface, a second liquid surface cleaning mode when the upstream end of the second flow channel 730 is in communication with the liquid surface, and an underwater cleaning mode when the upstream end of the second flow channel 730 is in communication with the underwater surface.

[0163] It should be noted that the power component can be the pump body 200 installed in the water tank cleaning base station 1 as described above, the power mechanism installed in the cleaning robot 7, or other power mechanisms installed independently of the water tank cleaning base station 1 and the cleaning robot 7.

[0164] And / or in another embodiment, when the cleaning robot 7 and the pool cleaning base station 1 are docked, the second flow channel 730 is connected to the first flow channel 130, and the connection between the second flow channel 730 and the first flow channel 130 is at least upstream of the sewage inlet flow channel section. By setting the second flow channel 730 to be connected to the first flow channel 130, and specifically setting the sewage inlet flow channel section and the second drain outlet 720 of the second flow channel 730 to be connected, on the one hand, the pump body 200 in the pool cleaning base station 1 can be used to collect the dirt collected in the second flow channel 730 (i.e., the dirt in the dust box 740) into the sewage inlet flow channel section; on the other hand, the pump body 200 in the pool cleaning base station 1 can also be used to clean the second sewage inlet 710 at the same time, thereby improving cleaning efficiency and optimizing cleaning effect.

[0165] In one embodiment, when the cleaning robot 7 docks with the pool cleaning base station 1, the second flow channel 730 is connected to the first flow channel 130, and the opening orientation and / or opening cross-sectional area of ​​the second inlet 710 and the first inlet 110 are different. This allows both the second inlet 710 and the first inlet 110 to clean floating debris, as described above. Furthermore, because the opening orientation and / or opening cross-sectional area of ​​the first inlet 110 and the second inlet 710 are different, the cleaning operation performed via the first inlet 110 produces different cleaning effects than the cleaning operation performed via the second inlet 710, thereby helping to improve the diversity and comprehensiveness of the pool cleaning system's cleaning capabilities within the pool 8.

[0166] In one embodiment, the upper end of the cleaning robot 7 is provided with a plate, which has multiple sieve holes, each sieve hole penetrating the plate along the walking direction of the cleaning robot 7. Thus, when the water tank cleaning base station 1 is operating in liquid surface cleaning mode and the cleaning robot 7 is in a separated state and independently operating its own related working mode, the cleaning robot 7 can move within the water tank 8, for example, by returning to the water tank cleaning base station 1, and the plate can carry floating debris far from the water tank cleaning base station 1 closer to the first sewage inlet 110.

[0167] Furthermore, based on one or more of the above embodiments, the control device in the water tank cleaning base station 1 / water tank cleaning system of the hardware operating environment involved in the embodiments of the present invention may include: a processor, such as a central processing unit (CPU), a communication bus, a user interface, a network interface, and a memory. The communication bus is used to realize the connection and communication between these components. The user interface may include a display screen, an input unit such as a keyboard, and optionally, a standard wired interface or a wireless interface. The network interface may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk storage device. The memory may also optionally be a storage device independent of the aforementioned processor.

[0168] The memory, as a storage medium, may include an operating system, a network communication module, a user interface module, and a control program for a water tank cleaning system.

[0169] In the aforementioned control device, the network interface is primarily used for data communication with the network server; the user interface is primarily used for data interaction with the user; the processor and memory in the control device of this invention can be located within the control device itself. The control device can be installed in the water tank cleaning base station 1 / water tank cleaning system. The control device uses the processor to call the control program for the water tank cleaning system stored in the memory and executes the control method for the water tank cleaning system provided in this embodiment of the invention.

[0170] This invention provides a control method for a water tank cleaning system. It is understood that this control method for the water tank cleaning system can be based on the water tank cleaning base station 1 and / or the water tank cleaning system described in any of the above embodiments.

[0171] Please refer to the following for details. Figure 9 , Figure 9 This is a flowchart illustrating the first embodiment of a control method for a water tank cleaning system according to the present invention.

[0172] Specifically, the control methods for the water tank cleaning system include:

[0173] Step S100: Upon receiving the liquid surface cleaning instruction, obtain the target spacing and target water discharge plan;

[0174] In this embodiment, the user can manually trigger the liquid surface cleaning command through the above-mentioned input module; or the liquid surface cleaning command can be automatically triggered by establishing the interrelationship between the liquid surface cleaning command and other working modes of the pool cleaning system, the installation status of the pool cleaning system, the running time of the pool cleaning system, etc. through pre-compiled programs.

[0175] When a surface cleaning command is triggered, the control device operates in surface cleaning mode. In this mode, the control device first needs to determine the target spacing and target effluent scheme based on the current water tank 8. The target spacing refers to the distance between the lower edge of the first inlet 110 and the current water surface of the water tank 8, which adjusts the liquid level difference formed at the first inlet 110 based on the current water tank 8, thereby affecting the suction intensity of the floating debris entering the first inlet 110. The target effluent scheme can be, but is not limited to, the opening orientation, opening cross-sectional area, and / or flow velocity of the first outlet 120, which adjusts the flow rate and / or water pressure of the water discharged through the first outlet 120, thereby affecting whether the floating debris in the cleaning blind zone of the first inlet 110 can flow more quickly and completely to the first inlet 110.

[0176] It is understood that the target spacing and / or target water discharge scheme can be constant, fixed values. In this case, the target spacing and / or target water discharge scheme are generated by default from a preset program associated with the liquid level cleaning command. That is, the control device, for example, has pre-stored relevant target spacing and / or target water discharge scheme information in its memory, and then when the liquid level cleaning command is triggered and executed, this information is retrieved and used directly.

[0177] Alternatively, the target spacing and / or target effluent scheme are set to values ​​that can be adjusted within a certain range depending on the specific conditions of the pool 8 to be cleaned:

[0178] In one embodiment, the water tank cleaning base station 1 also includes an input module, which generates the target spacing and / or target water discharge scheme. The user visually observes the specific condition of the water tank 8 to be cleaned and, based on experience, roughly determines the values ​​of the target spacing and / or target water discharge scheme. This value is then input through the input module, allowing the control device to generate the corresponding target spacing and / or target water discharge scheme, which is ultimately executed by the first and / or second adjustment mechanisms.

[0179] Alternatively, in another embodiment, the water tank cleaning base station 1 further includes a detection module, which is used to detect the position parameters of the unit relative to the water tank 8 and / or the parameters of the floating dirt at the liquid surface in the water tank 8; the steps of obtaining the target spacing and the target water discharge scheme include:

[0180] Step S110: Control the detection module to start running and obtain the actual values ​​of environmental parameters;

[0181] Step S120: Query the preset database to obtain the target spacing and target water discharge scheme that are associated with the actual values.

[0182] In this embodiment, the detection module is mainly used to sense the position parameters of the machine body relative to the water tank 8 and / or the state parameters of the floating dirt on the surface of the liquid in the water tank 8.

[0183] The positional parameters of the robot body relative to the pool 8 can include, but are not limited to, the specific installation position of the robot body on the pool wall 81 to be installed, the height of the liquid level in the pool 8 relative to the robot body, and the condition of the pool wall adjacent to the side wall to be installed. Correspondingly, the detection module can be, but is not limited to, photoelectric sensors, image recognition sensors, and ranging devices. By clarifying the positional information of the robot body relative to the side wall to be installed, and the quantity, orientation, and distance of the pool walls adjacent to the side wall to be installed, a three-dimensional model of the current pool 8 can be roughly constructed. This allows for the calculation and determination of, for example, the orientation and size of the cleaning blind spot related to the first sewage inlet 110, and also assists in creating the optimal walking path for the cleaning robot 7. Clarifying the height of the liquid level in the pool 8 relative to the robot body helps in calculating the actual distance, that is, the distance between the lower edge of the first sewage inlet 110 and the current liquid level of the pool 8.

[0184] The state parameters of the floating debris on the surface of the water tank 8 can include, but are not limited to, the approximate quantity, distribution, and type of the floating debris. Correspondingly, the detection module can be, but is not limited to, an image recognition sensor, a water quality detection module, or a photoelectric sensor. Once the state parameters of the floating debris on the surface of the water tank 8 are determined, the difficulty of cleaning the floating debris in the water tank 8 can be roughly estimated, and a targeted cleaning strategy can be developed. This provides reference data for adjusting the position of the lower edge of the first inlet 110 and the opening orientation / cross-sectional area / flow velocity of the first outlet 120. Furthermore, it provides sufficiently accurate measurement data for the operation of the water quality adjustment module.

[0185] Step S200: Control the first adjustment mechanism to adjust the position of the lower edge of the first sewage inlet 110 according to the target spacing;

[0186] In this embodiment, once the target spacing is determined, the control device can adjust the position of the lower edge of the first sewage inlet 110 according to the target spacing. Specifically:

[0187] When the machine body can move up and down relative to the tank wall 81 as described above, the first adjusting mechanism can be controlled to move the machine body up or down, thereby adjusting the position of the lower edge of the first sewage inlet 110. When the cover 150 / roller 610 / mounting frame / counterweight is provided as described above, the first adjusting mechanism can be controlled to move the cover 150 / roller 610 / mounting frame / counterweight up or down, thereby adjusting the position of the lower edge of the first sewage inlet 110.

[0188] Step S300: Control the second regulating mechanism to adjust the opening orientation and / or opening cross-sectional area of ​​the first drain outlet 120 according to the target water discharge scheme;

[0189] In one design scheme, the second adjustment mechanism can adjust the first drain outlet 120 to a target state according to the target water discharge scheme, that is, adjust the opening orientation, opening cross-sectional area and / or flow velocity of the first drain outlet 120 to a target value, and then complete the adjustment operation.

[0190] Based on this, when at least two first drain outlets 120 are provided on the same side of the first sewage inlet 110, and each first drain outlet 120 is arranged sequentially at intervals along the longitudinal direction, the second adjustment mechanism can adjust the openings of each first drain outlet 120 located on the same side to gradually deflect towards the first sewage inlet 110; and / or adjust the cross-sectional area of ​​the openings of each first drain outlet 120 located on the same side to gradually increase in the direction away from the first sewage inlet 110; and / or adjust the flow velocity at each first drain outlet 120 located on the same side to gradually increase in the direction away from the first sewage inlet 110. In this way, the water flow discharged outward through each first drain outlet 120 in a radial pattern can almost cover the entire cleaning blind area on the side of the first sewage inlet 110, and through the gradually changing water flow pressure, floating dirt farther away from the first sewage inlet 110 can be gradually driven towards the first sewage inlet 110.

[0191] In another design, the second adjustment mechanism can adjust the first drain outlet 120 to switch back and forth between the first target state and the second target state according to the target water discharge scheme. That is, after adjusting the opening orientation, opening cross-sectional area and / or flow velocity of the first drain outlet 120 from the first target value to different second target values, it switches back to the first target value and so on, repeating this cycle at least once until the adjustment operation is finally completed.

[0192] Based on this, regardless of whether there is one or at least two first drain outlets 120 on the same side of the first sewage inlet 110, specifically, the second adjustment mechanism can adjust the angle D between the opening orientation of the first drain outlet 120 and the opening orientation of the first sewage inlet 110 from large to gradually decrease, forming a dynamic water flow. Furthermore, the second adjustment mechanism can also adjust the opening cross-sectional area of ​​the first drain outlet 120 to gradually decrease, and / or adjust the flow velocity of the first drain outlet 120 to gradually decrease... and so on, repeating this cycle at least once.

[0193] Step S400: Before, simultaneously with, or after the first sewage inlet 110 and the first drainage outlet 120 are adjusted into place, control the pump body 200 to start operation.

[0194] In this embodiment, the adjustment process of the first regulating mechanism for the first sewage inlet 110 is generally completed before or simultaneously with the start-up of the pump body 200. The adjustment process of the second regulating mechanism for the first sewage outlet 120 can be completed before, simultaneously with, or after the start-up of the pump body 200.

[0195] Furthermore, when the machine body also includes a rotating module as described above, the power component can be started before or simultaneously with the step of controlling the pump body 200 to drive the blades 620 to rotate, thereby achieving the purpose of driving the floating dirt at the first inlet 110 into the first flow channel 130 faster and more completely.

[0196] Furthermore, when cleaning robot 7 is used as an aid to clean floating debris on the liquid surface, as described above:

[0197] In one embodiment, the control method for the water tank cleaning system includes:

[0198] Step A100: Obtain the current operating mode of the cleaning robot 7;

[0199] Step A200: When confirming that the working mode is within the range of the first preset mode, confirm whether to activate the first liquid surface cleaning mode;

[0200] Step A300: If so, control the power components and water tank to operate using the cleaning base station 1.

[0201] In this embodiment, when it is confirmed that the cleaning robot 7 is in operation, certain working modes of the cleaning robot 7 can be specifically associated with the situation where the water tank cleaning base station 1 needs to run the first liquid surface cleaning mode. This effectively combines the operation of the cleaning robot 7 with the cleaning of floating dirt on the liquid surface by the water tank cleaning base station 1.

[0202] First, it is necessary to select the working mode that the cleaning robot 7 needs to associate with the first liquid surface cleaning mode of the pool cleaning base station 1, that is, to construct the first preset mode range. The first preset mode range can be set by the system default of the whole machine or defined by the user. For example, when the cleaning robot 7 also has a charging mode and a dirt collection mode after being in the above docking state, the first preset mode range can specifically include, but is not limited to, one or more of the underwater cleaning mode, charging mode, and dirt collection mode. The charging mode is to charge the cleaning robot 7 with the help of the pool cleaning base station 1; the dirt collection mode is to clean the dirt in the dust box of the cleaning robot 7 with the help of the pool cleaning base station 1. That is, when it is confirmed that the cleaning robot 7 is currently running the underwater cleaning mode, charging mode, or dirt collection mode, the control device can automatically control the pool cleaning base station 1 to run the first liquid surface cleaning mode.

[0203] Of course, after step A200 above, the following also includes:

[0204] Step A400: When it is confirmed that the working mode is within the range of the second preset mode, the first liquid surface cleaning mode is deactivated.

[0205] It is understandable that when it is confirmed that the cleaning robot 7 is in operation, certain working modes of the cleaning robot 7 can be specifically associated with the situation where the pool cleaning base station 1 cannot operate the first liquid surface cleaning mode. This means that the operation of the cleaning robot 7 and the cleaning of floating debris on the liquid surface by the pool cleaning base station 1 can be reasonably staggered. Similarly, it is first necessary to select the working modes in which the cleaning robot 7 needs to operate in sequence with the first liquid surface cleaning mode of the pool cleaning base station 1, that is, to construct a second preset mode range. The second preset mode range can be set by the system default or defined by the user. For example, the aforementioned second preset mode range may include, but is not limited to, the second liquid surface cleaning mode. That is, when it is confirmed that the cleaning robot 7 is currently operating in the second liquid surface cleaning mode, the control device can automatically control the pool cleaning base station 1 to deactivate the first liquid surface cleaning mode.

[0206] Furthermore, in another embodiment, the control method for the pool cleaning system includes:

[0207] Step B100: Upon receiving the first liquid level cleaning instruction, obtain the target path;

[0208] Step B200: Control the cleaning robot 7 to walk along the target path, and during the walking process, control the second drain outlet 720 of the cleaning robot 7 to face the first sewage inlet 110.

[0209] In this embodiment, when the first liquid surface cleaning command is received as described above, the pool cleaning base station 1 operates according to steps S100 to S400 as described above. Simultaneously or in advance, the control device acquires the target path. This target path can be manually confirmed by the user through an input mode, it can be the system default, or it can be generated by the pool cleaning system after constructing the model of the current pool 8 through the various detection modules described above.

[0210] Once the target path is confirmed, the control device controls the cleaning robot 7 to move along the target path. During movement, the cleaning robot 7 can operate its own relevant working mode (either a second liquid surface cleaning mode or an underwater cleaning mode), such as cleaning the side walls and bottom walls of the pool 8; or the cleaning robot 7 can not operate its own working mode, but only be used to assist the first liquid surface cleaning mode operated by the pool cleaning base station 1. During this process, it is ensured that at least one second drain outlet 720 of the cleaning robot 7 always faces the first sewage inlet 110. With the force of the water flow discharged from the second drain outlet 720, floating dirt around the cleaning robot 7 is carried towards the first sewage inlet 110, making it easier for it to be sucked up and cleaned by the first sewage inlet 110. Correspondingly, the control device can adjust the opening orientation, opening cross-sectional area, and / or flow rate of the second drain outlet 720.

[0211] Furthermore, when the cleaning robot 7 is used to assist in cleaning floating debris on the liquid surface as described above, and the cleaning robot 7 is equipped with a plate, in a further embodiment, if the cleaning robot 7 moves towards the cleaning base station 1 of the pool, the control device can also control the cleaning robot 7 to move the floating debris in the distance towards the first sewage inlet 110 through the plate during its movement, thereby further improving the cleaning efficiency and cleaning quality of the first sewage inlet 110 for floating debris on the liquid surface.

[0212] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
