[0001] The present application claims priority from the Chinese patent application entitled “Pool Robot” and application number 2023102690674, filed with the Chinese Patent Office on March 20, 2023, which is incorporated in full by reference into the present application. Technical field

[0002] The present application relates to the technical field of pool equipment, in particular a pool robot. Technical background

[0003] The pool robot is an automated device designed for use in pools and can independently perform tasks such as cleaning the pool, thus saving users time and enjoying great popularity.

[0004] Since pool robots operate in water, there are two common problems with current pool robots that significantly impact the user experience and have long remained unresolved. First, when the pool robot is in the water, a large amount of water accumulates inside it, making it difficult to remove. Second, the water inside the pool robot must be drained after it is removed, but the drainage rate is relatively slow. Disclosure of registration

[0005] The purpose of this application is to specify a pool robot designed to increase the drainage speed when the pool robot emerges from the water, thereby quickly reducing the weight of the pool robot and improving the user experience.

[0006] To solve this problem, the application proposes the following design: a pool robot, which includes the following: a housing which is provided on its lower surface with a first water outlet opening, wherein a receiving chamber is provided on the housing, a dirt box arranged in the receiving chamber, the receiving chamber being provided with a second water outlet opening on its side wall; and a water retention plate which is partially connected to a side of the side wall of the receiving chamber facing away from the dirt box, wherein the water retention plate is arranged to cover the second water outlet opening and, when the pool robot is in the water, to close it; wherein the water retention plate (300) is opened while the pool robot leaves the water, so that the water in the dirt box flows out through the second water outlet opening and exits the housing through the first water outlet opening.

[0007] Optionally, the water retention plate is made of a flexible, waterproof material.

[0008] Optionally, the water retention plate, under the influence of water pressure, rests against the outer side wall of the second water outlet opening, both inside and outside the water outlet, thus sealing the second water outlet opening when the pool robot is in the water. However, when the pool robot leaves the water, the water retention plate is located below the debris box, so that the debris box, due to its gravity, presses against the water retention plate, thereby opening it.

[0009] The water retention plate optionally includes the following: a base body arranged to cover the second water outlet opening; and a rotating shaft which is arranged between the side wall and the base body and is located above the second water outlet opening, wherein the base body is rotatably connected to the rotating shaft.

[0010] Optionally, the surface area of ​​the water retention plate facing the second water outlet opening is larger than the area of ​​the second water outlet opening, with a circumferential edge of the water retention plate being partially connected to the side wall.

[0011] Optionally, the second water outlet opening is located near the lower surface of the housing.

[0012] The pool robot also optionally includes the following: a filter element that is located on one of the inner walls of the dirt box associated with the second water outlet opening.

[0013] Optionally, the area of ​​the first water outlet opening is 2000 mm². 2 up to 6000 mm 2 .

[0014] The pool robot also optionally includes the following: a handle located at the front end of the housing, whereby when the handle is raised, the side wall provided with the second water outlet tilts.

[0015] Optionally, the first water outlet opening is located near the lowest point of the housing when the handle is raised.

[0016] Optionally, when the handle is raised, the lower surface of the housing forms an angle of 45° to 75° with the horizontal plane.

[0017] Optionally, when the handle is raised, the first water outlet is located below the second water outlet.

[0018] Optionally, the dirt box is equipped with a liquid inlet and a liquid outlet, and the pool robot further includes the following: A filter drive assembly by means of which the pool robot can be driven to draw water from the pool, so that water enters the dirt box through the liquid inlet opening, whereby after filtration through the dirt box, waste remains in the dirt box, while the filtered water exits through the liquid outlet opening.

[0019] Optionally, the first water outlet opening is present multiple times, with the multiple first water outlet openings arranged in an array.

[0020] Optionally, the second water outlet opening is present multiple times, with the multiple second water outlet openings arranged in an array.

[0021] Furthermore, a pool robot is offered which includes the following: a housing which is provided on its lower surface with a first water outlet opening, wherein a receiving chamber is provided on the housing, a dirt box arranged in the receiving chamber, the receiving chamber being provided with a second water outlet opening on its side wall; and A water retention plate, partially connected to a side of the receiving chamber's side wall facing away from the dirt box, wherein the water retention plate is arranged to cover the second water outlet opening and, when the water pressure inside the second water outlet opening is greater than the water pressure outside the housing, rests against a side of the side wall facing away from the dirt box; whereas the water retention plate opens when the water pressure inside the second water outlet opening is less than the water pressure outside the housing, so that the dirt box, by its gravity, causes the water retention plate to detach from the side wall at the point where it is not connected to the side wall, creating a gap so that water can escape rapidly through the gap.

[0022] Furthermore, a pool robot is offered which includes the following: a housing which is provided on its lower surface with a first water outlet opening, wherein a receiving chamber is provided on the housing, a dirt box arranged in the receiving chamber, the receiving chamber being provided with a second water outlet opening on its side wall; and a water retention plate partially connected to a side of the side wall of the receiving chamber facing away from the dirt box, wherein the water retention plate is arranged to cover the second water outlet opening in order to be able to close or release the second water outlet opening; wherein the water retention plate opens when the side wall tilts due to the movement of the pool robot, so that the water in the dirt box flows out through the second water outlet opening and exits the housing through the first water outlet opening.

[0027] In the description of the present embodiment, the terms "top," "bottom," "left," "right," etc., are used in relation to the representation in the respective figure, solely to facilitate the description and simplify operation. In other words, these terms neither implicitly nor explicitly refer to the positioning, design, and operation of the device or element in question in a predetermined position, so that there is no limitation of the present application in this respect either. Furthermore, the terms "first" and "second" are used only for differentiation and have no special meaning.

[0028] As in Fig. 1, Fig. 2, Fig. 3 to Fig. Figure 4 illustrates this embodiment of a pool robot designed for operation in a pool. Currently, common pool robots are primarily used for cleaning the floor and walls of pools. The pool robot comprises a housing 100 and a debris box 200, the housing 100 having a receiving chamber 120 in which the debris box 200 is located. It is understood that the pool robot further comprises a filter drive assembly 500, and that the debris box 200 is provided with a liquid inlet and a liquid outlet.With the help of the filter drive assembly 500, the pool robot can be driven to draw water from the pool, so that water enters the dirt box 200 through the liquid inlet opening, whereby after filtration by the dirt box 200, waste remains in the dirt box 200, while the clean liquid exits through the liquid outlet opening.

[0029] When the pool robot is operating in the water, water enters the housing 100 through various gaps, resulting in a significant amount of water remaining inside the robot. When users attempt to remove the robot, the weight of the water inside the housing makes it so heavy that lifting the robot body requires considerable effort. Furthermore, due to the slow drainage rate of the housing 100, it takes a considerable amount of time to completely remove all the water after the robot body is lifted out of the water, which is time-consuming and could negatively impact the user experience.

[0030] As in Fig. 1 and Fig. As shown in Figure 2, in the present embodiment, the housing 100 is provided on its lower surface with a first water outlet opening 110, so that the water in the housing 100 can quickly escape through the first water outlet opening 110 when the pool robot emerges from the water (i.e., leaves the water surface) or after it has surfaced. Furthermore, the receiving chamber 120 is provided on its side wall with a second water outlet opening 130. The pool robot also includes a water retention plate 300, which is partially (i.e.,(only a part thereof) is connected to a side of the side wall of the receiving chamber 120 facing away from the dirt box 200, the water retention plate 300 being arranged to cover the second water outlet opening 130 and, when the pool robot is in the water, to close it to prevent water from entering the dirt box 200 through the second water outlet opening 130 and thus impairing the efficiency of the pool robot. When the pool robot emerges from the water (i.e., while leaving the water surface) or after it has emerged, the water retention plate 300 opens, allowing the water in the dirt box 200 to drain through the second water outlet opening 130 and exit the housing 100 through the first water outlet opening 110.This allows for rapid drainage of the dirt box 200, thus accelerating the drainage process when the pool robot emerges from the water. This quickly reduces the robot's weight and improves the user experience. During the immersion process, water enters the housing 100 through the first water outlet opening 110, rapidly increasing the robot's weight. This enables quick immersion and increases the efficiency of the immersion process.

[0031] Optionally, the water retention plate 300 is made of a flexible, waterproof material. Under the influence of water pressure, the water retention plate 300 rests against the outer side wall of the second water outlet opening 130, both inside and outside the pool robot, to prevent water from draining from the dirt box 200 through the second water outlet opening 130 and from water entering from the outside through the second water outlet opening 130. When the pool robot emerges from the water, the water outside the dirt box 200 quickly exits through the first water outlet opening 110, reducing the pressure outside the dirt box 200. As a result, the dirt box 200, under its own weight, causes the water retention plate 300 to detach from the side wall at the point where it is not connected, creating a gap through which water can quickly escape.The water retention plate 300 can selectively close the second water outlet opening 130 without additional drive force, which reduces costs and simplifies the assembly of the pool robot.

[0032] In another embodiment, the water retention plate 300 comprises a base body and a rotating shaft, the base body being arranged to cover the second water outlet opening 130. The rotating shaft is located between the side wall and the base body and is situated above the second water outlet opening 130. The base body is rotatably connected to the rotating shaft so that, when the pool robot emerges from the water, the base body rotates due to the weight of the water, thus exposing the second water outlet opening 130. It should be noted that the term "above" here refers to the side of the pool robot facing away from the bottom when the pool robot is on the bottom.

[0033] Optionally, the surface area of ​​the water retention plate 300 facing the second water outlet opening 130 is larger than the surface area of ​​the second water outlet opening 130, in order to completely cover the second water outlet opening 130. Optionally, a circumferential edge of the water retention plate 300 is partially connected to the side wall. That is, the circumferential edge of the water retention plate 300 is only partially connected to the side wall, so that water can escape from the debris box 200 at the point where the water retention plate 300 is not connected to the side wall after the pool robot has emerged from the water. In particular, such a connection between the circumferential edge of the water retention plate 300 and the side wall can refer to each edge of the water retention plate 300 being partially connected to the side wall.Thus, when the pool robot is underwater, the water pressure outside the side wall prevents the water in the debris box 200 from escaping through the second water outlet 130. As soon as the pool robot leaves the water surface, the water pressure outside the water retention plate 300 disappears. Now, the water pressure inside the debris box 200 causes the water retention plate 300 to detach from the side wall at the point where it is not connected to it, allowing the water in the debris box 200 to drain through the second water outlet 130. It is understood that the circumferential edge of the water retention plate 300 can also be connected to the side wall in sections as follows: the water retention plate 300 is connected to the side wall at least at one edge, with this edge encompassing at least the upper edge of the water retention plate 300 facing away from the bottom.This allows the edges of the water retention plate 300, which are not connected to the side wall, to detach from this side wall when the pool robot emerges from the water, in order to release the second water outlet opening 130, which enables fast and efficient drainage.

[0034] The second water outlet opening 130 is located further on, as in Fig. 1 and Fig. 2 shown, near the lower surface of the housing 100, which allows the water in the dirt box 200 to be drained and the residual water to be reduced.

[0035] Optionally, the first water outlet opening 110 is present multiple times, with the multiple first water outlet openings 110 arranged in an array, while the second water outlet opening 130 is present multiple times, with the multiple second water outlet openings 130 arranged in an array, which helps to increase the drainage area and ensure stability during the drainage process. Optionally, the first water outlet opening 110 and the second water outlet opening 130 are designed in a circular or grid-like form.

[0036] Optionally, the pool robot can also include a filter element that is located on one of the inner walls of the dirt box 200 associated with the second water outlet opening 130, in order to prevent waste from escaping from the dirt box 200 during the drainage process.

[0037] Optionally, the area of ​​the first water outlet opening is 110 x 2000 mm². 2up to 6000 mm 2 , which allows for sufficient surface area for drainage and thus greater efficiency in the drainage process.

[0038] As in Fig. 2 and Fig. As shown in Figure 3, the pool robot also includes a handle 400 located at the front end of the housing 100, which the user can use to hold it. When the handle 400 is raised, the side wall, which is equipped with the second water outlet 130, tilts. It should be noted that the front end is the end that is at the front when the pool robot is moving. This causes the water in the debris box 200 to drain out through the second water outlet 130 under the influence of gravity, thus enabling an efficient drainage process. Furthermore, the amount of water drained can be increased so that no residual water remains in the debris box 200.

[0039] To ensure that the water can completely drain from the housing 100, the interior of the pool robot has no right-angled corners or dead zones to prevent residual water from remaining and not draining completely. Optionally, when the handle 400 is raised, the lower surface of the housing 100 forms an angle of 45° to 75° with the horizontal plane, allowing water to drain naturally under the influence of gravity, thus increasing the amount of water removed. In the present embodiment, when the handle 400 is raised, the lower surface of the housing 100 forms an angle of 45° with the horizontal plane.

[0040] In the present embodiment, the first water outlet opening 110 is located near the lowest point of the housing 100 when the handle 400 is raised. When the user lifts the pool robot using the handle 400, water flows downwards under the influence of gravity. Therefore, the first water outlet opening 110 can contribute to less residual water in the housing and a higher proportion of the drained water if it is located near the lowest point of the housing 100 when the user holds the handle.

[0041] As in Fig.As shown in Figure 4, both the dirt box 200 and the intake chamber 120 are provided with a water inlet opening 140 on their side wall, located near the upper surface of the housing 100. During the immersion process of the pool robot, water from outside the housing 100 can enter the dirt box 200 through the water inlet opening 140, rapidly increasing the weight of the pool robot. This enables quick immersion and further increases the efficiency of the immersion process of the pool robot.

[0042] Optionally, the water inlet opening 140 is designed in a grid shape, so that it has a large open area and thus improves the efficiency of the immersion process.

[0043] It is understood that the filter drive assembly 500 is located at least partially outside the water inlet opening 140, so that when the pool robot is operating in the water, the filter drive assembly 500 causes water and debris to enter the dirt box 200 through the liquid inlet opening. After filtration by the dirt box 200, the debris remains in the dirt box 200, while the water is drained through the liquid outlet opening and the water inlet opening 140 to the filter drive assembly 500 and then exits the housing 100 along a predetermined path.

[0044] It should be noted that the principles, features, and advantages of the present application have been presented and described so far. Those skilled in the art will understand that the embodiments described above do not constitute a limitation of the present application, but merely serve to illustrate its principles.
