Description

Technical Field

[0001] This application relates to the technical field of automatic cleaning of water tanks, and more particularly to an automatic cleaning device for water tanks. Background Technology

[0002] With the increasing popularity of swimming pools, cleaning them has become a crucial aspect of their use, leading to a growing number of advanced automatic pool cleaning devices.

[0003] Current automatic pool cleaning devices, in addition to underwater and surface cleaning functions, can also clean the pool's sidewalls. These devices can be driven by a water pump to move or maintain their position against the pool's sidewall. For example, when moving along the pool, the pump can guide water from the bottom into the trash can and drain it from the top. The reaction force from the drainage creates a positive pressure on the cleaning device relative to a supporting surface (e.g., the pool wall), providing friction and enabling the device to move and clean along the pool wall. If the trash can becomes clogged, drainage is limited, and the device may slip off the pool wall while attempting to clean. Utility Model Content

[0004] This application addresses the shortcomings of the prior art by providing an automatic water tank cleaning device, comprising: a main body including a drain outlet and a bottom inlet communicating with the drain outlet; a trash basket disposed within the main body; a water pump capable of guiding water flow into the bottom inlet, through the trash basket, and out of the drain outlet for filtration; an opening located at the head of the main body, having a channel structure between the opening and the water pump, wherein water flowing into the channel structure bypasses the trash basket; and an opening / closing structure disposed at the opening, capable of switching between an open state and a closed state to allow the channel structure to communicate with or be separated from the external environment.

[0005] The embodiments described in this application have the following beneficial effects: Through the channel structure of the automatic water tank cleaning device provided in this application, the water pump is in fluid communication with the outside of the automatic water tank cleaning device. In this case, when the automatic water tank cleaning device is running, the drain outlet of the water pump can ensure a stable drainage volume, thereby keeping the automatic water tank cleaning device stable on the side wall of the water tank or stabilizing the posture of the automatic water tank cleaning device.

[0013] The embodiments of this disclosure will now be described with reference to the accompanying drawings. The described embodiments are merely some, not all, of the embodiments described herein. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the protection scope of this application. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0014] This application provides an automatic pool cleaning device. This automatic pool cleaning device is capable of cleaning pools. The pool is, for example, a pool-shaped structure. The pool-shaped structure can be a swimming pool, a water storage tank, a spa pool, a water storage tank, a water storage trough, etc. The automatic pool cleaning device can be a device such as an automatic cleaning device or a pool cleaning robot, capable of cleaning the pool-shaped structure. This application does not limit the specific presentation of the automatic pool cleaning device or the pool-shaped structure, as long as the principle of this application is achieved. In the following description, unless otherwise specified, a robot will be used as an example of the automatic pool cleaning device, and a swimming pool will be used as an example of a pool or pool-shaped structure. In the following description, unless otherwise specified, the terms "pool bottom," "pool bottom surface," and "pool base" all refer to the bottom surface of the swimming pool.

[0015] The robot can operate in three modes when cleaning a pool: bottom cleaning mode, pool wall cleaning mode, and surface cleaning mode. Bottom cleaning mode is the traditional operating mode currently available in automated pool cleaning devices. In this mode, the robot moves along the bottom of the pool to clean it. Pool wall cleaning mode, also known as wall-climbing mode, involves the robot attaching to and moving along the pool wall to clean it.

[0016] In the task of cleaning the pool by the robot, the waterline on the pool wall is usually the focus of the cleaning.

[0017] For example, during the cleaning process, the robot can use a roller brush or similar structure to physically clean the bottom and / or walls of the pool, removing dirt and grime adhering to them. For areas requiring focused cleaning, such as water lines, the robot can use a reciprocating motion to increase cleaning intensity. The robot can use a water pump to draw water from the pool through the suction port and discharge it through the drain port. A filter basket can be installed inside the robot. During the water pumping process, dirt and grime are drawn into and retained in the basket as the water flows through it, thus achieving the purpose of cleaning the pool. In other words, the automatic pool cleaning device includes a filter channel that restricts water flow sequentially through the suction port, the filter basket, and the drain port to remove waste / dirt.

[0018] It is worth noting that when the trash can is clogged, the filter channel does not receive sufficient fluid replenishment, thus creating a negative pressure state and insufficient water pump suction and drainage. With the robot positioned against the side wall of the pool, insufficient water pump suction and drainage will result in insufficient positive pressure between the robot and the side wall, causing the robot to slip off the side wall.

[0019] Furthermore, when the robot emerges from the water, ambient air enters its interior, causing air pockets and resulting in unstable water pump output. For example, after the robot is submerged, it takes some time for the trapped air to dissipate, during which time the water pump's output is inconsistent. This instability in water pump output leads to unstable positive pressure on the robot relative to supporting surfaces (e.g., pool bottom or wall surfaces), making it difficult to adjust the robot to the intended posture.

[0020] For example, the drain outlet of the water pump can be located at the head of the robot, and the direction of drainage can be upward away from the top of the robot (here, "upward" means the direction in which the top of the robot points when the robot is placed on a horizontal surface in a normal posture).

[0021] When the robot cleans the sidewall of the pool by moving back and forth near the waterline, air can easily get mixed into the water flow and enter the water inlet, causing the water pump's drainage volume to be unstable. As mentioned above, when the water pump's drainage volume is unstable, the robot is prone to slipping off the sidewall.

[0022] The following is combined with Figure 1A , Figure 1B and Figure 2 This application provides a detailed description of the automatic water tank cleaning device. Figure 1A This is a structural schematic diagram of the automatic water tank cleaning device of this application from a first angle. Figure 1B This is a second-angle structural schematic diagram of the automatic water tank cleaning device of this application. Figure 2 This is a cross-sectional structural schematic diagram of the automatic water tank cleaning device of this application.

[0023] This application provides an automatic water tank cleaning device 10. For example... Figure 1A , Figure 1B and Figure 2 As shown, the automatic water tank cleaning device 10 includes: a main body 100, including a drain outlet 102 and a bottom water inlet 101 communicating with the drain outlet 102; a trash basket 103 disposed within the main body 100; a water pump 104, which guides water flow from the bottom water inlet 101, through the trash basket 103, and out of the drain outlet 102 for filtration; an opening 105 located at the head of the main body 100, with a channel structure 106 between the opening 105 and the water pump 104, allowing water flow entering the channel structure 106 to bypass the trash basket 103; and an opening / closing structure 107 disposed at the opening 105, which can switch between an open state and a closed state to allow the channel structure 106 to communicate with or be separated from the external environment.

[0024] It is understood that the main body 100 can be a frame for the automatic pool cleaning device 10, housing its various components. The main body 100 can accommodate and provide support and protection for these components. These components may include, for example, a power unit, a filtration unit, a drive unit, and a controller. Based on these different components, the main body 100 can perform basic functions such as movement, filtration, and navigation.

[0025] It should be understood that the above description of the subject 100 is merely exemplary and does not constitute a limitation on the various parameters and functions of the subject 100. Those skilled in the art can select and set the subject 100 according to actual needs, as long as the principle of this application can be achieved.

[0026] It is understandable that the drain outlet 102 can be a part where water flows out from inside the main body 100. It is worth noting that when water is drained through the drain outlet 102, the main body 100 is subjected to a force in the opposite direction to the direction of water discharge.

[0027] It should be understood that the above description of the drain outlet 102 is merely exemplary and does not constitute a limitation on the various parameters and functions of the drain outlet 102. Those skilled in the art can select and set the drain outlet 102 according to actual needs, as long as the principle of this application can be achieved.

[0028] It is understood that the bottom inlet 101 can be a location where water flows into the interior of the main body 100. The bottom inlet 101 can be located at the bottom of the main body 100. The bottom inlet 101 allows water and impurities to enter the filter channel inside the main body 100. It is understood that the filter channel, located inside the main body 100, can be a passage connecting the bottom inlet 101 and the drain outlet 102. The trash basket 103 is located within the filter channel to filter the fluid flowing through it.

[0029] It is understood that the trash can 103 may include a frame and a filter screen disposed on the frame. The trash can 103 is used to filter impurities and dirt from the water flow to purify the water in the pool.

[0030] It should be understood that the above description of the filter channel is merely exemplary and does not constitute a limitation on the filter channel. Those skilled in the art can design the above filter channel according to actual needs, as long as it can achieve the principle of this application.

[0031] During the robot's movement and / or cleaning operations, fluid can enter the filter channel through the bottom inlet 101 and flow along the filter channel to the outlet 102. It should be understood that the fluid can be water or a water-air mixture, and the fluid may contain impurities (e.g., gravel, twigs, leaves, algae, or insects).

[0032] An opening 150 may be provided at the head of the main body 100. For example, the opening 150 may be located on the main body 100, with the opening 105 positioned near the top of the main body 100 when the main body 100 is in a preset posture, so that gas inside the main body 100 can be discharged through the opening 105. It is understood that the head direction of the main body 100 may be the direction of forward movement when the robot moves forward. The opening 150 may have a certain size and shape, which facilitates the flow of water and air through the opening 150 into the channel structure 106.

[0033] A channel structure 106 is provided between the opening 105 and the water pump 104. That is, the channel structure 106 allows the opening 105 to communicate with the water pump 104. In some embodiments, since the trash can 103 is blocked, water flowing through the trash can 103 would prevent the additional water flow from the opening 105 from being discharged smoothly. Therefore, the water flow entering from the channel structure 106 bypasses the trash can 103. For example, when the water pump 104 is located between the trash can 103 and the opening 105, the water flow entering the channel structure 106 from the opening 105 will be directly sucked away by the water pump 104, thus the water flow does not pass through the trash can 103. Alternatively, the trash can 103 is located between the opening 105 and the water pump 104. In this case, the channel structure 106 is configured to allow the water flow to bypass the trash can 103, such as a channel around the trash can 103, so that most of the water flow entering from the opening 105 does not pass through the trash can 103 and is directly sucked away by the water pump 104. Therefore, in the event of a blockage in the trash can 103, water from the external environment can reach the water pump 104 through the opening 105 and the channel structure 106, and be discharged from the drain outlet 102, so as to avoid a reduction in the drainage capacity of the water pump 104 due to the blockage of the trash can 103.

[0034] It should be understood that the above description of the channel structure 106 and opening 105 is merely exemplary and does not constitute a limitation on the channel structure 106 and opening 105. Those skilled in the art can design the above channel structure 106 and opening 105 according to actual needs, as long as the principle of this application can be achieved.

[0035] The opening / closing structure 107 can switch between an open state and a closed state to allow the channel structure 106 to connect with or separate from the external environment. Based on the state of the opening / closing structure 107, the channel structure 106 can connect with or separate from the external environment.

[0036] The states of the opening and closing structure 107 are described in detail below.

[0037] If the opening / closing structure 107 is closed, the channel structure 106 is isolated from the external environment. The robot is in a first predetermined state (e.g., the trash can 103 is not blocked), and water flows into the filter channel through the bottom inlet 101, passes through the trash can 103, and is discharged through the drain outlet 102. The isolation of the channel structure 106 from the external environment prevents water from reaching the drain outlet 102 of the water pump 104 through the opening 105 and the channel structure 106. In this case, the power of the water pump 104 can be better applied to the robot's bottom inlet 101, thereby improving cleaning efficiency.

[0038] If the opening / closing structure 107 is in the open state, the channel structure 106 is connected to the external environment. Water from the external environment flows through the opening 105 and the channel structure 106 to the drain outlet 102 of the water pump 104. This provides a water flow channel for the water pump even if the trash can 103 is blocked, thus ensuring the robot's friction on the pool wall surface and preventing the robot from slipping off. When the automatic cleaning device switches from an exposed state to a submerged state on the pool wall, the opening 105 can be used to expel air from inside the cleaning device, increasing the water inlet rate of the cleaning device.

[0039] The open state of the opening and closing structure 107 is in response to the satisfaction of a predetermined condition.

[0040] Understandably, when the robot is in its first predetermined state, water can enter from the bottom inlet 101, pass through the filter channel, and be discharged from the outlet 102. In this case, the opening / closing structure 107 does not necessarily need to be in the open state.

[0041] For example, in the event of a blockage in the trash can 103 or an unstable drainage rate from the water pump 104, the opening / closing structure 107 can be in an open state to allow the channel structure 106 to communicate with the external environment. That is, the open state of the opening / closing structure 107 is in response to the fulfillment of a predetermined condition.

[0042] The predetermined conditions include: the tilt angle of the main body 100 relative to the horizontal plane; and / or the rotational speed of the water pump 104; and / or the flow rate of the drain outlet 102 or the bottom inlet 101.

[0043] For example, the predetermined condition includes the tilt angle of the main body 100 relative to the horizontal plane. If the tilt angle of the main body 100 relative to the horizontal plane is greater than or equal to the predetermined angle, the predetermined condition is met, and the opening / closing structure 107 is in the open state. For example, the predetermined angle can be 70 degrees. When the robot is cleaning the pool wall, the tilt angle of the main body 100 relative to the horizontal plane is 90 degrees or close to 90 degrees (greater than the predetermined angle). In this case, the opening / closing structure 107 is in the open state, which facilitates the exhaust of air inside the robot through the opening / closing structure 170 from the opening 105. Furthermore, when the robot is on the surface of the pool wall, the open state of the opening / closing structure 107 allows water to flow through the opening 105 and the channel structure 106 to the water pump, thereby preventing the robot from slipping off due to blockage of the trash can.

[0044] For example, the predetermined condition includes the rotational speed of the water pump 104. When the trash can 103 is clogged or the drainage volume of the water pump 104 is unstable, the rotational speed of the water pump 104 becomes abnormal (e.g., the pump's rotational speed is greater than or equal to a predetermined rotational speed threshold). That is, the predetermined condition is met, the opening / closing structure 107 is open, allowing water to flow through the opening 105 and the channel structure 106 to the water pump, thereby preventing the robot from slipping off the pool wall due to the trash can clog. For example, when the trash can 103 is clogged, the drainage volume of the drain outlet 102 decreases, and the rotational speed of the water pump 104 increases. As another example, when air mixed with fluid is discharged from the drain outlet 102, the drainage volume of the drain outlet 102 becomes unstable, and correspondingly, the rotational speed of the water pump 104 also becomes unstable. Whether the rotational speed of the water pump 104 is abnormal can also indicate whether the trash can 103 is clogged and / or whether the drainage volume of the drain outlet 102 is stable.

[0045] For example, the predetermined condition includes the flow rate of the drain outlet 102 or the bottom inlet 101. Blockage of the trash can 103 will cause a reduction in the flow rate of the bottom inlet 101 and / or the drain outlet 102. If the flow rate of the drain outlet 102 or the bottom inlet 101 is less than a predetermined flow rate threshold, the predetermined condition is met, and the opening / closing structure 107 is in the open state, allowing water to flow through the opening 105 and the channel structure 106 to reach the water pump, thereby preventing the robot from slipping off the obstacle course due to blockage of the trash can. The unstable drainage volume of the water pump 104 can be determined based on changes in the flow rate of the bottom inlet 101 and / or the drain outlet 102.

[0046] It should be understood that the above description of the predetermined conditions is merely exemplary and does not constitute a limitation on the predetermined conditions. Those skilled in the art can select and set the above predetermined conditions according to actual needs, as long as the principle of this application can be achieved.

[0047] When the opening and closing structure 107 is in the open state and the automatic pool cleaning device 10 is located on the pool wall, the channel structure 106 is in communication with the external water environment; and / or, when the automatic pool cleaning device 10 is located at the waterline, the channel structure 106 is in communication with the external air environment; and / or, when the automatic pool cleaning device 10 moves downward from the waterline, the air inside the main body 100 can be discharged through the opening 105.

[0048] For example, when the opening and closing structure 107 is in the open state and the automatic cleaning device 10 of the pool is located on the pool wall, the channel structure 106 is in communication with the external water environment.

[0049] If the trash can 103 becomes clogged, a negative pressure forms within the filter channel, resulting in insufficient flow from the filter channel to the drain outlet 102. This could cause the robot to slip on the pool wall or fall off. With the opening 105 below the water surface, water from the external water environment can enter the channel structure 106 through the opening 105, reach the water pump 104, and be discharged from the drain outlet 102 to compensate for the flow rate at the drain outlet 102.

[0050] For example, if the opening / closing structure 107 is in the open state, the channel structure 106 is in communication with the external air environment when the robot is at the waterline. When the robot is at the waterline, the water level inside the main body 100 can be approximately level with the water level in the pool.

[0051] For example, when the automatic cleaning device for the pool is lifted out of the pool and detached from the pool, because the channel structure 106 is connected to the external air environment, the outside air continuously and unobstructedly enters the bottle through the opening, replenishing the space vacated after the liquid flows out in real time. The robot's air pressure is always balanced with the external atmospheric pressure, and no "negative pressure obstruction" is formed, which improves the water discharge rate of the automatic cleaning device for the pool.

[0052] For example, if the portion of the head of the main body 100 above the water surface increases, the buoyancy force on the main body 100 decreases. Correspondingly, the weight of the main body 100 needs to decrease to keep it attached to the pool wall. When the opening / closing structure 107 is open, outside air can enter the main body 100 through the opening 105 and the channel structure 106, facilitating water drainage from the main body 100 and reducing its weight. This allows the main body 100 to be held attached to the pool wall by the combined effects of gravity, buoyancy, support force, and friction.

[0053] For example, during the robot's downward movement along the pool wall, some air needs to be expelled from the main body 100 to reduce buoyancy. With the opening / closing structure 107 open, internal air can be expelled from the main body 100 through the channel structure 106 and the opening 105, reducing buoyancy and facilitating the robot's submersion.

[0054] Understandably, during the process of cleaning the waterline area, the robot can move up and down repeatedly to allow the roller brush to clean the waterline area multiple times. As the robot moves back and forth, the opening and closing structure 107 can be flexibly controlled to switch between open and closed states, thereby facilitating the entry and exit of water and air into and from the robot, ensuring the robot's operational stability and improving its cleaning efficiency.

[0055] For example, when the opening and closing structure 107 is in the open state and the automatic water cleaning device 10 moves downward from the water line, the air inside the main body 100 can be discharged through the opening 105.

[0056] During the process of the robot descending into the water along the side wall of the pool, or during the process of the robot cleaning the pool wall, air may be present inside the main body 100. For example, during the cleaning process, the cleaning components agitate the water flow, causing the water to mix with air and enter the bottom inlet 101. When the opening and closing structure 107 is in the open state, as the main body 100 moves downward from the waterline, the air inside the main body 100 can be discharged through the opening 105 to ensure a stable drainage volume from the drain outlet 102.

[0057] It should be understood that the above description of the channel structure 106 and the external environment is merely exemplary and does not constitute a limitation on the channel structure 106. Those skilled in the art can select and set the channel structure 106 and the external environment according to actual needs, as long as the principle of this application can be achieved.

[0058] The automatic pool cleaning device 10 also includes a controller that can control the opening and closing structure 107 to switch between the open state and the closed state; and / or, the opening 105 is located on the upper side and / or the front side of the main body head.

[0059] The controller is capable of controlling the opening / closing structure 107 to switch between an open state and a closed state. It is understood that the controller can be a microcontroller or other control components. The controller can be integrated inside the main body 100 or it can be a remote controller. The remote controller can remotely control the opening / closing structure 107 via a communication network. For example, when the predetermined conditions are met, the controller sends a signal to the opening / closing structure 107 to control the opening / closing structure 107 to switch between the open state and the closed state.

[0060] It should be understood that the above description of the controller is merely exemplary and does not constitute a limitation on the controller. Those skilled in the art can select and configure the above controller according to actual needs, as long as it can achieve the principle of this application.

[0061] The following is combined Figure 3A and Figure 3B The opening and closing structure 107 is described in detail. Figure 3A This is a schematic diagram of the opening and closing structure of an example of this application (the pivot hinge is located in the first position). Figure 3B This is a schematic diagram of the opening and closing structure of an example of this application (the pivot hinge is located in the second position).

[0062] The opening and closing structure 107 includes a pivot hinge portion 1071 to switch the opening and closing structure 107 between an open state and a closed state.

[0063] For example, the opening / closing structure 107 may include a pivot hinge portion 1071 and a hole. The pivot hinge portion 1071 can block the hole to place the opening / closing structure 107 in a closed state. The pivot hinge portion 1071 can also open the hole to place the opening / closing structure 107 in an open state.

[0064] For example, the pivot hinge 1071 can rotate to switch the opening and closing structure 107 between an open state and a closed state. For instance, when the pivot hinge 1071 is rotated to a first position, the pivot hinge 1071 blocks the hole, putting the opening and closing structure 107 in a closed state. When the pivot hinge 1071 is rotated to a second position, the pivot hinge 1071 opens the hole, putting the opening and closing structure 107 in an open state.

[0065] The opening and closing structure 107 also includes a counterweight 1072, which is located on the side away from the pivot hinge portion 1071.

[0066] For example, the opening and closing structure 107 may further include a counterweight 1072. The counterweight 1072 may be disposed on the side away from the pivot hinge portion 1071. The function of the counterweight 1072 is to adjust the center of gravity of the pivot hinge portion 1071 so that when the main body 100 is in a predetermined posture, the pivot hinge portion 1071 can be quickly rotated to a first position or a second position.

[0067] It should be understood that the above description of the opening and closing structure 107 is merely exemplary and does not constitute a limitation on the opening and closing structure 107. Those skilled in the art can select and set the above opening and closing structure 107 according to actual needs, as long as the principle of this application can be achieved.

[0068] The following is combined Figure 4 The isolation net and cleaning box of the automatic water tank cleaning device of this application are described in detail. Figure 4 This is a schematic diagram of the structure of a cleaning box as an example of this application.

[0069] The automatic cleaning device for the water tank also includes an isolation net 108, which is located at the opening 105 and is used to prevent dirt from entering the channel structure 106 through the opening 105.

[0070] For example, the isolation net 108 can be located at the connection between the opening 105 and the channel structure 106. During the process of water flowing from the external environment into the channel structure 106 through the opening 105, impurities carried in the water are filtered by the isolation net 108. It is worth noting that the mesh size of the isolation net 108 can be set according to actual conditions. For example, if there are a large number of small-volume impurities such as algae in the pool, the isolation net 108 can be set to a larger mesh size.

[0071] It should be understood that the above description of the isolation net 108 is merely exemplary and does not constitute a limitation on the isolation net 108. Those skilled in the art can select and configure the isolation net 108 according to actual needs, as long as the principle of this application can be achieved.

[0072] The automatic water tank cleaning device also includes a cleaning box 109, which is located at the opening 105. The isolation net 108 is located on the side wall or bottom wall of the cleaning box 109 and is set corresponding to the opening 105. The cleaning box 109 is used to collect the filter residue generated after the water flow is filtered by the isolation net 108, or to place disinfectant.

[0073] Exemplarily, the cleaning box 109 may be a box-shaped structure with an opening at the top. In one example, the isolation net 108 is disposed on the side wall of the cleaning box 109. In another example, the isolation net 108 is disposed on the bottom wall of the cleaning box 109. It is worth noting that the isolation net 108 may completely cover the connection between the opening 105 and the channel structure 106, or the isolation net 108 may partially cover the connection between the opening 105 and the channel structure 106.

[0074] Water from the external environment can enter the cleaning box 109 through the upper opening and pass through the isolation net 108 into the channel structure 106. As the water flows through the isolation net 108, impurities mixed in the water are intercepted by the isolation net 108, forming filter residue. This filter residue is collected inside the cleaning box 109 for cleaning.

[0075] The cleaning box 109 can also be used to hold disinfectant. When water flows into the cleaning box 109, the disinfectant can be used to disinfect the water. Additionally, the disinfectant can also disinfect the filter residue to reduce bacterial growth in the filter residue.

[0076] The cleaning box 109 is detachably mounted from the main body 100.

[0077] In some cases, the cleaning box 109 can be detached from the main body 100. For example, when the filter residue in the cleaning box 109 reaches a certain amount, the cleaning box 109 can be removed for cleaning or replacement. As another example, if the isolation mesh 108 is damaged, the cleaning box 109 can be removed for maintenance or replacement. This detachable connection can be specifically configured to be detachable via a snap-fit ​​structure or a magnetic structure, etc.
