Description

Technical Field

[0001] This invention relates to the field of water tank cleaning system technology, and specifically to a water tank cleaning system and its self-cleaning method. Background Technology

[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. Existing pool cleaning robots have relatively small filter chambers, resulting in a limited cleaning area. After working for a period of time, the filter screen in the filter box is easily clogged. Once the filter screen is clogged, the cleaning efficiency of the pool cleaning robot is greatly reduced. After the pool cleaning robot finishes cleaning, the user needs to manually remove the filter screen and rinse it, which is time-consuming and laborious. Summary of the Invention

[0003] The main objective of this invention is to propose a water tank cleaning system and its self-cleaning method, which aims to solve the problem of inconvenient manual cleaning of the filter box of traditional water tank cleaning robots.

[0004] To achieve the above objectives, the present invention provides a water tank cleaning system, comprising:

[0005] A base station includes a first housing, a first power component disposed on the first housing, and a first filter structure. The base station has a first sewage inlet, a first drainage outlet, and a first flow channel connecting the first sewage inlet and the first drainage outlet. The first filter structure is disposed within the first flow channel and divides the first flow channel into a first sewage inlet flow channel segment near the first sewage inlet and a first drainage outlet flow channel segment near the first drainage outlet.

[0006] A pool cleaning robot includes a second housing, a second power unit and a second filter structure disposed in the second housing. The pool cleaning robot is provided with a second sewage inlet, a second drain outlet and a second flow channel connecting the second sewage inlet and the second drain outlet. The second filter structure is disposed in the second flow channel and divides the second flow channel into a second sewage inlet flow channel section near the second sewage inlet and a second drain outlet flow channel section near the second drain outlet.

[0007] The water tank cleaning robot docks with the base station, causing the second sewage inlet to be in a docking state that is connected to the first sewage inlet. When in the docking state, the first power component is used to form a suction flow in the first drainage channel section and / or to form a pumping flow in the second drainage channel section, so as to carry the dirt in the second sewage inlet channel section to the first sewage inlet channel section.

[0008] Optionally, the water tank cleaning system further includes a docking pipe, which, when in the docking state, is connected between the first sewage inlet and the second sewage inlet.

[0009] Optionally, the docking pipe has a first channel and a second channel that are independently arranged radially therefrom;

[0010] When in the docking state, the first channel connects the first sewage inlet and the second sewage inlet, the second channel connects the second sewage inlet, and the first power component is used to form a suction flow in the first drainage channel section and a pumping flow in the second channel.

[0011] Optionally, the docking pipe has a first channel and a second channel that are independently arranged radially therefrom; the water tank cleaning system also includes a third power component;

[0012] When in the docking state, the first channel connects the first sewage inlet and the second sewage inlet, the second channel connects the second sewage inlet, the first power component is used to form a suction flow in the first drainage channel section, and the third power component is used to form a pumping flow in the second channel.

[0013] Optionally, when in the docking state, the second channel includes an extension channel section extending into the second sewage inlet section through the second sewage inlet, the channel opening of the extension channel section extending obliquely toward the side wall of the second sewage inlet section.

[0014] Furthermore, to achieve the above objectives, the present invention also provides a self-cleaning method for a pool cleaning system, wherein the pool cleaning system is as described above, and the self-cleaning method of the pool cleaning system includes:

[0015] Upon receiving a self-cleaning command, the system checks whether the first and second inlets are properly connected.

[0016] Once the first and second sewage inlets are confirmed to be connected, the first power unit is started.

[0017] Furthermore, to achieve the above objectives, the present invention also provides a self-cleaning method for a pool cleaning system, wherein the pool cleaning system is as described above, and the self-cleaning method of the pool cleaning system includes:

[0018] Upon receiving a self-cleaning command, the system checks whether the first and second inlets are properly connected.

[0019] When the first sewage inlet and the second sewage inlet are connected, the suction flow is controlled to form in the first drainage channel section and the pumping flow is controlled to form in the second channel.

[0020] Optionally, the suction water flow and the drum water flow are generated simultaneously.

[0021] Optionally, the suction water flow and the drum water flow are generated alternately.

[0022] Optionally, the intensity of the suction water flow is not less than the intensity of the drum water flow.

[0023] Furthermore, to achieve the above objectives, the present invention also provides a pool cleaning system, comprising:

[0024] The base station includes a first housing, a first power component disposed within the first housing, and a first filter structure. The first housing is provided with a first sewage inlet and a first drainage outlet.

[0025] A pool cleaning robot includes a second housing, a second power unit and a second filter structure disposed in the second housing, the second housing being provided with a second inlet and a second outlet;

[0026] The water tank cleaning robot is connected to the base station, the first sewage inlet is connected to the second filter structure, and the first power component draws water and / or the second power component blows water to carry the dirt in the second filter structure into the first filter structure.

[0027] In the technical solution provided by this invention, when the first sewage inlet and the second sewage inlet are connected, the first sewage inlet channel section and the second sewage inlet channel section are connected. At this time, the first power component forms a suction water flow in the first drainage channel section, which allows the sewage in the second sewage inlet channel section to be directly sucked into the first sewage inlet channel section under the drive of the suction water flow. Alternatively, the first power component forms a pumping water flow in the second drainage channel section, which allows the sewage in the second sewage inlet channel section to be directly pushed into the first sewage inlet channel section under the drive of the pumping water flow, thus completing the transfer of sewage from the pool cleaning robot to the base station. This allows for more efficient and convenient cleaning of the second sewage inlet channel section (i.e., the filter box) of the pool cleaning robot without relying on manual operation, which helps to improve the overall quality of the machine.

[0046] Please see Figures 1 to 9This invention provides a pool cleaning system that can be used to clean dirt from pools. The pool can be, but is not limited to, swimming pools, artificial ponds, etc. For ease of understanding, in the following embodiments, the base station 100 and its applied pool cleaning system are described as having two intersecting horizontal, vertical, and vertical directions. The horizontal and vertical directions are two directions approximately perpendicular to the vertical direction on a horizontal plane.

[0047] Specifically, the pool cleaning system provided by the present invention includes a base station 100 and a pool cleaning robot 200. The base station 100 includes a first housing 110, a first power component 130, and a first filter structure 120 disposed on the first housing 110. The first housing 110 has a first inlet 111, a first outlet 112, and a first flow channel 113 connecting the first inlet 111 and the first outlet 112. The first filter structure 120 is disposed within the first flow channel 113 and divides the first flow channel 113 into a first inlet flow channel segment 113a near the first inlet 111 and a first outlet flow channel segment near the first outlet 112. The pool cleaning robot 200 includes a second housing 210, a second power component, and a second filter structure 220 disposed on the second housing 210. The second housing 210 has a second inlet 211, a second outlet 120, and a second outlet 120. The system includes a water inlet 212 and a second flow channel 213 connecting the second sewage inlet 211 and the second drainage outlet 212. A second filter structure 220 is disposed within the second flow channel 213, dividing the second flow channel 213 into a second sewage inlet flow channel section 213a near the second sewage inlet 211 and a second drainage flow channel section near the second drainage outlet 212. The water tank cleaning robot 200 docks with the base station 100, causing the second sewage inlet 211 to be in a docking state that is connected to the first sewage inlet 111. When in the docking state, the first power component 130 is used to form a suction flow in the first drainage flow channel section and / or to form a pumping flow in the second drainage flow channel section, so as to carry the dirt in the second sewage inlet flow channel section 213a to the first sewage inlet flow channel section 113a.

[0048] In the technical solution provided by this invention, when the first sewage inlet 111 and the second sewage inlet 211 are connected, the first sewage inlet channel section 113a and the second sewage inlet channel section 213a are connected. At this time, the first power component 130 forms a suction water flow in the first drainage channel section, which allows the sewage in the second sewage inlet channel section 213a to be directly sucked into the first sewage inlet channel section 113a under the drive of the suction water flow. Alternatively, the first power component 130 forms a pumping water flow in the second drainage channel section, which allows the sewage in the second sewage inlet channel section 213a to be directly pushed into the first sewage inlet channel section 113a under the drive of the pumping water flow, thus completing the transfer of sewage from the pool cleaning robot 200 to the base station 100. This allows for more efficient and convenient cleaning of the second sewage inlet channel section 213a (i.e., the filter box) of the pool cleaning robot 200 without relying on manual operation, which helps to improve the overall quality of the machine.

[0049] Generally, the base station 100 includes a body, which includes a first housing 110 and some necessary components installed on the first housing 110. The first housing 110 is installed on the wall of the pool to be installed. The specific location of the pool wall to be installed is not limited, and it can be, but is not limited to, the bottom wall and / or side wall of the pool.

[0050] The first housing 110 may generally have a first sewage inlet 111, a first drain outlet 112, and a first flow channel 113 connecting the first sewage inlet 111 and the first drain outlet 112. The first sewage inlet 111 and / or the first drain outlet 112 may be directly formed on the first housing 110, or the first sewage inlet 111 and / or the first drain outlet 112 may be defined by forming mounting holes in the first housing 110 and then defining the first sewage inlet 111 and / or the first drain outlet 112 by other components assembled at the mounting holes.

[0051] The machine body also includes a first power component 130 and a first filter structure 120. The first power component 130 is located in the first flow channel 113 to drive external water to enter the first flow channel 113 from the first sewage inlet 111 and then discharge it outward through the first drain outlet 112. The first filter structure 120 is located in the first flow channel 113 to divide the first flow channel 113 into a first sewage inlet flow channel section 113a near the first sewage inlet 111 and a first drainage flow channel section near the first drain outlet 112. The first filter structure 120 is used to trap solids in the water at the first sewage inlet flow channel section 113a. The first filter structure 120 can be configured as one or at least two. When the first filter structure 120 is configured as at least two, each first filter structure 120 can divide one or at least two first sewage inlet flow channel sections 113a within the first flow channel 113. Therefore, when there are at least two first sewage inlet flow channel sections 113a, the filtration area can be increased, and the cleaning efficiency can be improved.

[0052] For example, the first sewage inlet 111 can be directly opened at the first housing 110, and the shell wall of the first housing 110 with the first sewage inlet 111 can be a straight shell wall, an outwardly convex shell wall, or an inwardly concave shell wall.

[0053] The first housing 110 is also provided with a first mounting hole, and the housing also includes a flow channel shell plate and a drain pipe. The flow channel shell plate is installed inside the first housing 110, and the flow channel shell plate is provided with a first through hole and a second through hole. The first through hole is sealed and connected to the first sewage inlet 111; the second through hole is correspondingly provided to the first mounting hole. The drain pipe passes through the first through hole and the first mounting hole in sequence, and is connected to the first power component 130, which is at least partially housed in the flow channel shell wall. When the first sewage inlet 111 is located on one longitudinal side of the first housing 110, the first drain outlet 112 can be located on both transverse sides of the first housing 110, at which time two drain pipes are correspondingly provided, and the two drain pipes are connected to the same first power component 130.

[0054] The first filter structure 120 is built into the flow channel shell plate. In this case, the cavity section within the flow channel shell plate located between the first filter structure 120 and the first through hole constitutes the aforementioned first sewage inlet flow channel section 113a; the cavity section within the flow channel shell plate located between the first filter structure 120 and the second through hole, together with the drain pipe body, constitutes the aforementioned first drainage flow channel section. The first filter structure 120 may be plate-shaped and radially spaced along the first flow channel 113; or the first filter structure 120 may be frame-shaped, enclosing and defining the first sewage inlet flow channel section 113a.

[0055] When the first power unit 130 starts running, a suction water flow is formed at the first flow channel 113. This suction water flow draws water from the water tank outside the first housing 110 into the first flow channel 113 through the first sewage inlet 111, and finally discharges it outward through the first drain outlet 112. During this process, solid waste and other pollutants carried in the water are trapped in the first sewage inlet section 113a by the first filter structure 120, achieving the purpose of sewage collection.

[0056] The specific forms of the second housing 210, second sewage inlet 211, second drain outlet 212, second filter structure 220, and second power component of the pool cleaning robot 200 are not limited. For example, they can be set up in the same way as above, and will not be described in detail here.

[0057] In view of the above, the base station 100 can generally be set to have a constant position relative to the pool wall to be installed; or it can be set to have a position relative to the pool wall to be installed that can be adjusted vertically, horizontally, and / or longitudinally. However, it is understood that when the position of the base station 100 relative to the pool wall to be installed can be adjusted vertically, horizontally, and / or longitudinally, the travel distance of the base station 100 is generally less than that of the pool cleaning robot 200, and / or the degree of freedom of the base station 100 is generally less than that of the pool cleaning robot 200.

[0058] Taking the position of base station 100 relative to the wall of the pool as constant as an example, the pool cleaning robot 200 can move freely within the pool. The pool cleaning system has a docking state where the pool cleaning robot 200 approaches the base station 100, causing the second sewage inlet 211 to align with the first sewage inlet 111, and a separation state where the pool cleaning robot 200 moves away from the base station 100, causing the second sewage inlet 211 to separate from the first sewage inlet 111. In the separation state, generally, the base station 100 can independently operate its preset functions, and the pool cleaning robot 200 can independently operate its preset functions. However, in the docking state, the pool cleaning system has at least a preset self-cleaning mode for the pool cleaning robot 200.

[0059] When the self-cleaning mode is running, since the first sewage inlet 111 and the second sewage inlet 211, that is, the first sewage inlet channel section 113a and the second sewage inlet channel section 213a are connected, at this time, by forming a driving water flow from the second sewage inlet channel section 213a to the first sewage inlet channel section 113a between the pool cleaning robot 200 and the base station 100, the dirt trapped in the second sewage inlet channel section 213a can be driven by the driving water flow to be carried into the first sewage inlet channel section 113a, thereby realizing the cleaning of the dirt in the second sewage inlet channel section 213a.

[0060] It should be noted that the first sewage inlet 111 and / or the second sewage inlet 211 can be set to one or at least two. When the first sewage inlet 111 and the second sewage inlet 211 are each provided with at least two, and when they are in the docking state, at least one set is docked and connected.

[0061] Based on this, the driving water flow can be directly obtained by the first power component 130. At this time, the first power component 130 has a first suction side and a first exhaust side. The first suction side may be connected to the first flow channel 113, and optionally, the first suction side may be connected to the first drainage flow channel section, generating a suction water flow. Under the action of this suction water flow, the water in the second sewage inlet flow channel section 213a is drawn into the first sewage inlet flow channel section 113a. And / or the first exhaust side may be connected to the second flow channel 213, and optionally, the first exhaust side may be connected to the second drainage flow channel section, generating a blasting water flow. Under the action of this blasting water flow, the water in the second sewage inlet flow channel section 213a is blasted into the first sewage inlet flow channel section 113a.

[0062] And / or, the driving water flow can be directly obtained by the second power component. In this case, the second power component has a second suction side and a second exhaust side. The second suction side may be connected to the first flow channel 113, and optionally, the second suction side may be connected to the first drainage flow channel section, generating a suction water flow, and under the action of the suction water flow, the water in the second sewage inlet flow channel section 213a is drawn into the first sewage inlet flow channel section 113a. And / or, the second exhaust side may also be connected to the second flow channel 213, and optionally, the second exhaust side may be connected to the second drainage flow channel section, generating a blowing water flow, and under the action of the blowing water flow, the water in the second sewage inlet flow channel section 213a is blown into the first sewage inlet flow channel section 113a.

[0063] And / or, the driving water flow can be directly obtained by an additionally provided third power unit 400. In this case, the third power unit 400 has a third suction side and a third exhaust side. The third suction side may be connected to the first flow channel 113, and optionally, the third suction side may be connected to the first drainage flow channel section, generating a suction water flow, and under the action of the suction water flow, the water in the second sewage inlet flow channel section 213a is drawn into the first sewage inlet flow channel section 113a. And / or, the third exhaust side may also be connected to the second flow channel 213, and optionally, the third exhaust side may be connected to the second drainage flow channel section, generating a blowing water flow, and under the action of the blowing water flow, the water in the second sewage inlet flow channel section 213a is blown into the first sewage inlet flow channel section 113a.

[0064] Furthermore, during the transfer of contaminants from the second inlet channel section 213a to the first inlet channel section 113a, some contaminants may remain in, for example, the second filter structure 220 within the second inlet channel section 213a. Therefore, in a further embodiment, in addition to generating the driving water flow from the second inlet channel section 213a to the first inlet channel section 113a as described above within the pool cleaning system, a vibrating water flow opposite to the driving water flow can also be generated separately within the second inlet channel section 213a. Driven by this vibrating water flow, contaminants, especially those retained in the second filter structure 220, are reversed and removed from the second filter structure 220, and then carried by the driving water flow to the first inlet channel section 113a, further optimizing the cleaning effect on the contaminants in the second inlet channel section 213a. It should be noted that the vibrating water flow generally only acts within the second flow channel 213 and is not limited to the first flow channel 113, so as to avoid the dirt collected under the drive of the driving water flow being carried out from the first flow channel 113 by the vibrating water flow.

[0065] Based on this, similarly to the above, the vibrating water flow can be the suction water flow generated by the first power component 130, the second power component, and / or the third power component 400 at the second sewage inlet 211, and under the action of this suction water flow, the dirt in the second sewage inlet section 213a near the second drainage section is sucked and driven towards the second sewage inlet 211. And / or, the vibrating water flow can be the surging water flow generated by the first power component 130, the second power component, and / or the third power component 400 at the second drainage section, and under the action of this surging water flow, the dirt in the second sewage inlet section 213a near the second drainage section is surging and driven towards the second sewage inlet 211.

[0066] Of course, another solution to achieve the goal of removing the dirt remaining at the second filter structure 220 is to install the second filter structure 220 in the second flow channel 213 in a vibratory manner, so that when the driving water flow acts on the first sewage inlet section 113a and the second sewage inlet section 213a, it can drive the second filter structure 220 to vibrate in the second flow channel 213, thereby shaking off the dirt at the second filter structure 220.

[0067] Based on one or more of the above embodiments, when in a docking state, the first sewage inlet 111 and the second sewage inlet 211 can be directly docked. At this time, the shell wall forming the first sewage inlet 111 and the shell wall forming the second sewage inlet 211 can be mutually abutting between flat surfaces, or they can be mutually abutting between an outer convex shell wall and an inner concave shell wall.

[0068] Alternatively, the pool cleaning system may also include a docking pipe 300, which, when docked, connects the first inlet 111 and the second inlet 211. It is understood that the docking pipe 300 may be integrally formed with the base station 100 and the pool cleaning robot 200. Alternatively, the docking pipe 300 may be a component independent of the base station 100 and the pool cleaning robot 200, only connecting to the first inlet 111 and the second inlet 211 when docked. In this case, the docking pipe 300 is movable relative to the base station 100 and / or the pool cleaning robot 200. When separated, the docking pipe 300 is separated from the first inlet 111 and / or the second inlet 211 and can be housed within the base station 100 and / or the pool cleaning robot 200. Specifically, for example, the docking pipe 300 may be configured as a telescopic pipe structure, extending when docking is required and retracting when separation is required.

[0069] Furthermore, a sealing structure may be provided between the first sewage inlet 111 and the second sewage inlet 211, between the first sewage inlet 111 and the docking pipe 300, and / or between the second sewage inlet 211 and the docking pipe 300. The sealing structure ensures that when in the docking state, the first sewage inlet 111 and the second sewage inlet 211 can be docked directly or indirectly through the docking pipe 300.

[0070] Based on the above embodiments, when it is necessary to form the aforementioned driving water flow and vibrating water flow, the docking pipe 300 is formed with a first channel 310 and a second channel 320 independently arranged radially. In the docking state, the first channel 310 connects to the first sewage inlet 111 and the second sewage inlet 211 to form a path for the driving water flow; the second channel 320 connects to the second sewage inlet 211 to form a path for the vibrating water flow. As described above, the first power component 130, the second power component, and / or the third power component 400 can be provided according to actual needs.

[0071] Furthermore, in one embodiment, when in the docked state, the second channel 320 includes an extension channel section 321 extending into the second sludge inlet section 213a via the second sludge inlet 211. The opening of the extension channel section 321 extends obliquely toward the sidewall of the second sludge inlet section 213a. The oblique opening of the extension channel section is configured as an angled opening and is inclined toward the sidewall of the second sludge inlet section 213a, so that the vibrating water flow formed through the extension channel section can act directly on the sidewall of the second sludge inlet section 213a, such as the second filter structure 220, with a larger flow rate and / or a larger flow velocity, thereby enabling the vibrating water flow to better remove residual dirt.

[0072] It should be noted that the present invention also provides a pool cleaning system, which specifically includes a base station 100 and a pool cleaning robot 200. The base station 100 and the pool cleaning robot 200 can be specifically configured based on any of the above embodiments. For example, base station 100 includes a first housing 110, a first power component 130 disposed within the first housing 110, and a first filter structure 120. The first housing 110 is provided with a first sewage inlet 111 and a first drain outlet 112. Pool cleaning robot 200 includes a second housing 210, a second power component disposed within the second housing 210, and a second filter structure 220. The second housing 210 is provided with a second sewage inlet 211 and a second drain outlet 212. The pool cleaning robot 200 is connected to base station 100, the first sewage inlet 111 is connected to the second filter structure 220, and the first power component 130 draws water and / or the second power component blows water to carry dirt from the second filter structure 220 into the first filter structure 120. It can be understood that the power source for collecting dirt from the second filter structure 220 into the first filter structure 120 can selectively originate from the first power component 130, the second power component, or both the first power component 130 and the second power component. After the base station 100 and the pool cleaning robot 200 are connected, the dirt in the second filter structure 220 can enter the first filter structure 120 through the second dirt inlet 211 and the first dirt inlet 111. Alternatively, the dirt in the second filter structure 220 can enter the first filter structure 120 through other pre-set openings in the pool cleaning robot 200 and the first dirt inlet 111.

[0073] Of course, the necessary components installed at the first housing 110 mentioned above may include, but are not limited to, one or more of the following: power supply module, control device 500, detection module, human-machine interaction module, etc.

[0074] 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 energy and protect the environment, and can support the long-term use of the base station 100. Among them, the wireless charging module can be integrated between the base station 100 for the pool and an external power source, or between the pool cleaning robot 200 and the base station 100 for the pool, reducing manual operation and increasing ease of use.

[0075] The detection module is located within the machine body and is used to detect environmental parameters at the machine's location. 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 together. The water quality detection module detects the parameters of the water in the current pool, and then the control device 500, based on the detected parameter values, determines that the water in the pool does not meet the standards, and accordingly controls the water quality adjustment module to adjust the water quality, for example, by releasing water quality adjustment reagents or using ultraviolet light for sterilization and disinfection.

[0076] The human-computer interaction module includes an input module. The input module is located on the device and is used to input numerical values. The input module can be configured as needed, for example, to input a voice recognition module or a display / control module; at least one of these can be selected. This establishes communication and interaction between the user and the base station 100. For example, the user can trigger commands via voice or touch to interact with the base station 100 for the water tank. The user can also input specific values ​​for relevant parameters through the input module. Of course, the base station 100 for the water tank can also use the human-computer interaction module to achieve purposes such as preset abnormal alarms, or the user can use a display screen to view relevant information about the water tank in real time, making the use of the base station 100 more intelligent and user-friendly.

[0077] In addition, based on one or more of the above embodiments, please refer to Figure 9 The control device 500 in the base station 100 / water tank cleaning system of the hardware operating environment involved in the embodiments of the present invention may include: a processor 510, such as a central processing unit (CPU), a communication bus 520, a user interface 530, a network interface 540, and a memory 550. The communication bus 520 is used to realize communication between these components. The user interface 530 may include a display screen and an input unit such as a keyboard; optionally, the user interface 530 may also include a standard wired interface or a wireless interface. The network interface 540 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 550 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk storage device. The memory 550 may also optionally be a storage device independent of the aforementioned processor 510.

[0078] The memory 550, which serves as a storage medium, may include an operating system, a network communication module, a user interface 530 module, and a self-cleaning program for a water tank cleaning system.

[0079] In the aforementioned control device 500, the network interface 540 is mainly used for data communication with the network server; the user interface 530 is mainly used for data interaction with the user; the processor 510 and memory 550 in the control device 500 can be located within the control device 500. The control device 500 can be located in the base station 100 / water tank cleaning system. The control device 500 uses the processor 510 to call the self-cleaning program of the water tank cleaning system stored in the memory 550 and executes the self-cleaning method of the water tank cleaning system provided in this embodiment of the invention.

[0080] This invention provides a self-cleaning method for a water tank cleaning system. It is understood that this self-cleaning method can be based on the base station 100 and / or the water tank cleaning system described in any of the above embodiments.

[0081] Please refer to the following for details. Figure 10 , Figure 10 This is a schematic flowchart of a first embodiment of a self-cleaning method for a water tank cleaning system according to the present invention. Specifically, the self-cleaning method of the water tank cleaning system includes:

[0082] Step A100: Upon receiving the self-cleaning command, check whether the first sewage inlet 111 and the second sewage inlet 211 have completed docking;

[0083] Step A200: When it is confirmed that the first sewage inlet 111 and the second sewage inlet 211 have completed docking, control the first power unit 130 to start operation.

[0084] In this embodiment, the user can manually trigger the self-cleaning command of the pool cleaning robot 200 through the above-mentioned input module; or the user can establish the correlation between the self-cleaning command of the pool cleaning robot 200 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, so as to realize the automatic triggering of the self-cleaning command of the pool cleaning robot 200.

[0085] When the self-cleaning command of the pool cleaning robot 200 is triggered, the control device 500 operates the self-cleaning mode of the pool cleaning robot 200 in accordance with the self-cleaning command. In this mode, the first step is to detect whether the first inlet 111 and the second inlet 211 are properly connected. Specifically, sensors can be pre-installed on the body and / or the pool wall to be installed. The sensors can be, but are not limited to, photoelectric sensors, pressure sensors, image recognition sensors, etc. When the sensors are activated, the connection status of the first inlet 111 and the second inlet 211 can be detected. Only when the first inlet 111 and the second inlet 211 are confirmed to be properly connected can the following self-cleaning steps be executed. If it is confirmed that the first inlet 111 and the second inlet 211 are not properly connected, an abnormal status prompt message can be issued to the user based on the above-mentioned prompt module. This abnormal status message allows users to promptly correct the installation status of the first sewage inlet 111 and the second sewage inlet 211, ensuring that the first sewage inlet 111 and the second sewage inlet 211 are properly connected.

[0086] Once the first sewage inlet 111 and the second sewage inlet 211 are properly connected, the first power component 130, the second power component and / or the third power component 400 can be started to operate, so as to generate driving water flow between the first sewage inlet section 113a and the second sewage inlet section 213a, and complete the self-cleaning process.

[0087] Or please refer to the specific details. Figure 11 , Figure 11 This is a schematic flowchart of a first embodiment of a self-cleaning method for a water tank cleaning system according to the present invention. Specifically, the self-cleaning method of the water tank cleaning system includes:

[0088] Step B100: Upon receiving the self-cleaning command, check whether the first sewage inlet 111 and the second sewage inlet 211 have completed docking;

[0089] Step B200: When the first sewage inlet 111 and the second sewage inlet 211 are connected, the suction flow is formed in the first drainage channel section and the pumping flow is formed in the second channel 320, respectively.

[0090] In this embodiment, the same principle applies as in the first embodiment described above:

[0091] Users can manually trigger the self-cleaning command of the pool cleaning robot 200 through the above input module; or they can establish the correlation between the self-cleaning command of the pool cleaning robot 200 and other working modes, installation status, and runtime of the pool cleaning system through pre-compiled programs, so as to realize the automatic triggering of the self-cleaning command of the pool cleaning robot 200.

[0092] When the self-cleaning command of the pool cleaning robot 200 is triggered, the control device 500 operates the self-cleaning mode of the pool cleaning robot 200 in accordance with the self-cleaning command. In this mode, the first step is to detect whether the first inlet 111 and the second inlet 211 are properly connected. Specifically, sensors can be pre-installed on the body and / or the pool wall to be installed. The sensors can be, but are not limited to, photoelectric sensors, pressure sensors, image recognition sensors, etc. When the sensors are activated, the connection status of the first inlet 111 and the second inlet 211 can be detected. Only when the first inlet 111 and the second inlet 211 are confirmed to be properly connected can the following self-cleaning steps be executed. If it is confirmed that the first inlet 111 and the second inlet 211 are not properly connected, an abnormal status prompt message can be issued to the user based on the above-mentioned prompt module. This abnormal status message allows users to promptly correct the installation status of the first sewage inlet 111 and the second sewage inlet 211, ensuring that the first sewage inlet 111 and the second sewage inlet 211 are properly connected.

[0093] Once the first sewage inlet 111 and the second sewage inlet 211 are properly connected, the first power component 130, the second power component, and / or the third power component 400 can be started to operate, thereby generating a driving water flow between the first sewage inlet channel section 113a and the second sewage inlet channel section 213a, and generating a vibrating water flow within the second sewage inlet channel section 213a. Specifically, the driving water flow is, for example, a suction water flow generated at the first drainage channel section; the vibrating water flow is, for example, a surging water flow generated at the second drainage channel section.

[0094] The suction water flow and the blowing water flow can be generated simultaneously, so that in the current state, the driving water flow drives the dirt in the second sewage inlet section 213a into the first sewage inlet section 113a. At the same time, the vibrating water flow drives the dirt remaining on the inner wall of the second sewage inlet section 213a and the second filter structure 220 to fall off and suspend in the second sewage inlet section 213a.

[0095] Alternatively, the suction flow and the pumping flow can be generated alternately, so that the process of the driving water flow propelling the contaminants from the second contaminant inlet section 213a into the first contaminant inlet section 113a, and the process of the vibrating water flow causing the contaminants remaining on the inner wall of the second contaminant inlet section 213a and at the second filter structure 220 to detach and suspend within the second contaminant inlet section 213a, do not occur simultaneously. The suction flow can operate at a first flow rate / first flow rate for a first duration and then stop, followed by the pumping flow operating at a second flow rate / second flow rate for a second duration and then stopping; then switching back to the suction flow operating at the first flow rate / first flow rate for a first duration and then stopping… and so on. In this way, mutual interference between the suction flow and the pumping flow within the second contaminant inlet section 213a can be completely avoided.

[0096] To optimize the self-cleaning effect of the pool cleaning robot 200, a further design can specifically set the intensity of the suction water flow to be no less than the intensity of the drum water flow. That is, specifically set the intensity of the driving water flow to be no less than the intensity of the vibrating water flow. The intensity of the water flow can be, but is not limited to, flow rate, flow velocity, and water pressure.

[0097] 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.
