[0032] In order to describe in detail the technical content, the achieved objectives and the effects of the present invention, the following is described in conjunction with the embodiments and with reference to the accompanying drawings.

[0033] A pool robot includes a body 1, a driving system, and a cleaning system and a diving system 5 disposed in the body 1. The driving system is disposed at the bottom of the body 1, and the driving system is used to drive the body 1 to move on the water surface or at the bottom of the pool.

[0034] Wherein, when the body 1 is put into the pool water, the diving system 5 controls the body 1 to float on the water surface of the pool or sink to the bottom of the pool; when the body 1 floats on the water surface of the pool, the cleaning system cleans the floating objects on the water surface of the pool; when the body 1 sinks to the bottom of the pool, the cleaning system cleans the sediment at the bottom of the pool.

[0035] The working principle of the present invention is briefly described as follows: When the pool robot provided by the present invention is actually used, the operator puts the pool robot into the pool water. The pool robot is controlled by a driving system to move on the pool surface or at the bottom of the pool. And the pool robot changes its buoyancy in the water through a diving system 5, so as to control the main body 1 to float on the pool surface or sink to the bottom of the pool. And when the pool robot floats on the pool surface, the pool robot can be used to clean and filter the floating objects on the pool surface through its cleaning system; when the pool robot sinks to the bottom of the pool, the pool robot cleans the sediment at the bottom of the pool through its cleaning system.

[0036] As can be seen from the above description, the beneficial effects of the present invention are as follows: This pool robot can not only float on the pool surface to clean the floating objects on the pool surface, but also sink to the bottom of the pool to clean the sediment at the bottom of the pool. Compared with the existing surface pool robots or pool wall robots, the pool robot provided by the present invention can meet the cleaning requirements of both the pool surface and the pool bottom at the same time, and the functions of this pool robot are more practical and rich.

[0037] Furthermore, the diving system 5 includes a water tank 6 and a drainage pump 8. The water inlet end of the drainage pump 8 is connected to the water tank 6 in a through manner, and the water outlet end of the drainage pump 8 is connected to the outside of the main body 1 in a through manner.

[0038] In some preferred embodiments of the present invention, a check valve is provided on the drainage pump. Among them, when the main body 1 needs to dive from the pool surface to the bottom for operation, the diving system 5 controls the water tank to be filled with water. Specifically, a hatch can be provided on the water tank, and the hatch is connected to the outside of the main body 1 in a through manner. And when the main body 1 floats on the water surface, the hatch is submerged below the water surface. Then when the diving system 5 needs to fill water, it controls the hatch to open, and water will pour into the water tank from the hatch; when the water tank is filled with water, the overall weight of the main body 1 increases, the overall buoyancy of the main body 1 in the water decreases, and the main body 1 sinks to the bottom of the pool under the action of the decreasing buoyancy; when the main body 1 needs to float from the bottom of the pool to the water surface, the drainage pump discharges the water inside the water tank. At this time, the overall weight of the main body 1 decreases, the overall buoyancy of the main body 1 in the water increases, and the main body 1 floats to the water surface under the action of the increasing buoyancy.

[0039] Furthermore, the water tank 6 and the drainage pump are arranged at the middle position of the bottom of the main body 1.

[0040] As can be seen from the above description, arranging the water tank 6 and the drainage pump at the middle position of the bottom of the main body 1 is more beneficial for the main body 1 to maintain the balance of the fuselage and avoid the fuselage of the main body 1 from tilting due to uneven weights on both sides.

[0041] In some other preferred embodiments of the present invention, the water tanks 6 and the drainage pumps may also be provided on both opposite sides of the body 1.

[0042] As can be seen from the above description, in practical applications, the diving system 5 may specifically include two water tanks 6 and two drainage pumps. Among them, each water tank 6 is correspondingly provided with a drainage pump and is respectively arranged on the opposite sides of the body 1. When the body 1 is in the water of the swimming pool, the body 1 can adjust the balance of its fuselage through the water tanks 6 and the drainage pumps on both sides of it.

[0043] Of course, in some preferred embodiments, according to specific usage requirements, the diving system 5 may also be provided with multiple water tanks 6, and each water tank 6 is correspondingly provided with a drainage pump to meet the diving and floating requirements of the pool cleaning robot in different working environments.

[0044] Furthermore, the diving system 5 further includes a water inlet pump 7, an air inlet valve 9 and an air outlet valve 10. The drainage pump 8 and the water inlet pump 7 are arranged at the bottom of the water tank. The water inlet end of the water inlet pump 7 is connected to the outside of the body 1 in a penetrating manner, and the water outlet end of the water inlet pump 7 is connected to the water tank 6 in a penetrating manner. The air inlet valve 9 and the air outlet valve 10 are arranged at the top of the water tank 6. The air inlet of the air inlet valve 9 is connected to the outside of the body 1 in a penetrating manner, the air outlet of the air inlet valve 9 is connected to the water tank 6 in a penetrating manner, the air inlet of the air outlet valve 10 is connected to the water tank 6 in a penetrating manner, and the air outlet of the air outlet valve 10 is connected to the outside of the body 1 in a penetrating manner.

[0045] In some other preferred embodiments of the present invention, the diving system 5 injects the water in the swimming pool into the water tank 6 through the water inlet pump 7, the drainage pump 8 discharges the water in the water tank 6, the air inlet valve 9 injects air into the water tank 6, and the air outlet valve 10 discharges the air in the water tank 6;

[0046] In practical applications, when the pool robot needs to sink from the water surface of the swimming pool to the bottom, the water inlet pump 7 injects the water in the swimming pool into the water tank 6, and the air outlet valve 10 discharges the air inside the water tank 6, thereby increasing the overall weight of the body 1. The buoyancy of the body 1 in the water decreases, and the body 1 sinks to the bottom of the swimming pool; when the pool robot needs to float from the bottom of the swimming pool to the water surface, the drainage pump 8 discharges the water in the water tank 6. The overall weight of the body 1 decreases as the water in the water tank 6 decreases, and the buoyancy of the body 1 in the water increases as its weight decreases, and the body 1 floats to the water surface;

[0047] To improve the working efficiency of the drainage pump 8 and the water inlet pump 7, the drainage pump 8 and the water inlet pump 7 can be arranged at the bottom of the water tank 6; when the drainage pump 8 discharges the water in the water tank 6, the operation of the drainage pump 8 and the water flow discharged by it generate an upward power on the main body 1, making the pool robot float to the water surface more quickly. When the pool robot floats to the water surface, the air intake valve 9 automatically opens under the action of air pressure and injects air into the water tank 6, enabling the main body 1 to obtain a better floating effect.

[0048] Furthermore, the diving system 5 further includes a water separation detection module, and the water separation detection module is arranged on the main body 1.

[0049] In some preferred embodiments of the present invention, the water separation detection module is arranged at the top of the main body 1. When the main body 1 floats to the water surface, the water detection module detects that the top of the main body 1 is not in contact with the water body. At this time, the main control system 12 of the main body 1 can determine that the main body 1 is currently floating on the water surface and can correspondingly control the main body 1 to adjust its own balance and float and move on the water surface.

[0050] Furthermore, the drive system includes a motor, rollers 2 and / or a crawler, and the drive end of the motor is connected to the rollers 2 and / or the crawler.

[0051] In some preferred embodiments of the present invention, the drive system controls the rollers 2 to rotate through the motor, so that when the main body 1 is at the bottom of the pool, the main body 1 can move autonomously on the bottom of the pool through the rollers 2.

[0052] Of course, in some other preferred embodiments of the present invention, the drive system controls the crawler to rotate through the motor, so that when the main body 1 is at the bottom of the pool, the crawler drives the main body 1 to move autonomously on the bottom of the pool.

[0053] In addition, in some preferred embodiments, in order to enhance the movement ability of the pool cleaning robot, the operator can sleeved a crawler on the rollers 2 to make the main body 1 move more smoothly in the water.

[0054] Furthermore, the drive system further includes a bottom contact sensing module, and the bottom contact sensing module is arranged at the bottom of the main body 1.

[0055] As can be seen from the above description, the bottom contact sensing module is used to sense whether the bottom of the main body 1 is in contact with the bottom of the pool. When the bottom contact sensing module senses and detects that the main body 1 is in contact with the bottom of the pool, the main control system 12 of the pool robot will control the drive module to work.

[0056] Further, the cleaning system includes a first recovery bin 11, a first water inlet 13 and a first water outlet. The first recovery bin 11 is disposed in the main body 1. The first water inlet 13 is opened on the main body 1, and the first water outlet is opened on the side wall and / or the bottom of the main body 1. The first recovery bin 11 is respectively and communicatively connected to the first water inlet 13 and the first water outlet.

[0057] As can be seen from the above description, as Figure 1 shown, in some preferred embodiments of the present invention, the first recovery bin 11 is disposed inside the main body 1, and the main body 1 is provided with a first water inlet 13 and a first water outlet that are respectively and communicatively connected to the first recovery bin 11. When the cleaning system is cleaning, the water in the swimming pool is injected into the first recovery bin 11 from the first water inlet 13. The first recovery bin 11 filters solids such as sundries and garbage in the water, and discharges the filtered water from the first water outlet.

[0058] Among them, in some preferred embodiments of the present invention, the side wall of the first recovery bin 11 is mesh-shaped. After the water and solid sundries enter the first recovery bin 11 from the first water inlet 13, the water directly flows out from the mesh holes, and the solid sundries are intercepted by the mesh-shaped side wall of the first recovery bin 11 and remain in the first recovery bin 11.

[0059] In some other preferred embodiments of the present invention, the side wall of the first recovery bin 11 is a solid plate, and the first water outlet is mesh-shaped. At this time, the solid sundries are intercepted by the first water outlet.

[0060] Among them, if the first water outlet is opened on the side wall of the main body 1, when the first drain port drains water to the outside of the main body 1, the water flow formed by the drainage of the first drain port can generate a certain thrust on the main body 1, thereby helping the main body 1 to move in the water; if the first water outlet is opened at the bottom of the main body 1, when the main body 1 is in a floating state on the water surface, the first water outlet drains water downward at the bottom of the main body 1. At this time, the water flow formed by the drainage of the first water outlet can generate a certain upward thrust on the main body 1, so that the main body 1 can float better on the water surface. Of course, in some preferred embodiments of the present invention, the operator can open the first water outlet on the side wall and the bottom of the main body 1 respectively.

[0061] In addition, the operator can set the first water outlet on the side wall or the bottom of the main body 1, or can set the first water outlet on the side wall and the bottom of the main body 1 respectively.

[0062] Further, the cleaning system includes a first recovery bin 14, a first water inlet 15 and a filtering through hole. The first recovery bin 14 is disposed on the main body 1. The first water inlet 15 is provided on one side of the first recovery bin 14 close to the forward direction, and the first recovery bin 15 is provided with the filtering through hole along its circumference.

[0063] As described above, as Figure 5 shown, in some other preferred embodiments of the present invention, the first recovery bin 14 is provided outside the main body 1, and a first water inlet 15 and a filtering through hole are provided on the first recovery bin 14. When the pool robot floats on the water surface, water and floating objects enter the first recovery bin 14 from the first water inlet 15, the water is discharged through the filtering through hole on the first recovery bin 14, and the floating objects are intercepted in the first recovery bin 14 by the filtering through hole.

[0064] Furthermore, the cleaning system further includes a roller 3 and a plurality of scraping blades 4. The plurality of scraping blades 3 are provided on the roller 4, and the roller 4 is provided in the first water inlet.

[0065] In some preferred embodiments of the present invention, the cleaning system further includes a roller 3 motor, and the roller 3 motor drives the roller 3 to rotate. The scraping blades 4 on the roller 3 can drive the floating objects to enter the first recovery bin from the first water inlet during the rotation process, and the scraping blades 4 stir the water surface during the rolling process of the roller 3, and drive the main body 1 to produce a moving effect on the water surface.

[0066] Of course, in some other alternative embodiments of the present invention, the first water inlet 13 can be provided on one side of the main body 1 close to the forward direction, and the main body 1 can be driven to move on the water surface by setting mechanisms such as a propulsion device. Then, even if the roller 3 is not provided with a roller 3 motor, the roller 3 will rotate under the action of the scraping blades 4 and the water flow, and drive the floating objects on the pool water surface to enter the first recovery bin 11 from the first water inlet 13.

[0067] Furthermore, the cleaning system further includes a second water inlet, and the second water inlet is provided at the bottom of the main body or the first recovery bin.

[0068] As described above, in order to further improve the cleaning effect of the pool robot on the bottom of the pool, a second water inlet is provided at the bottom of the main body or the first recovery bin. The second water inlet is closer to the bottom of the pool. Therefore, the sediment at the bottom of the pool can enter the first recovery bin from the second water inlet, and the cleaning system has a better cleaning effect on the sediment at the bottom of the pool.

[0069] Among them, as Figure 1 shown, when the first recovery bin 11 is provided inside the main body 1, the second water inlet is provided at the bottom of the main body 1, and the second water inlet is connected to the first recovery bin 11 in a through manner;

[0070] As Figure 5 shown, when the first recovery bin 14 is provided outside the main body 1, the second water inlet is provided at the bottom of the first recovery bin 14.

[0071] In some preferred embodiments of the present invention, for the convenience of controlling the first water inlet and the second water inlet during actual application, a first water inlet valve may be provided on the first water inlet, and a second water inlet valve may be provided on the second water inlet, so as to control the opening or closing of the first water inlet by using the first water inlet valve and control the opening or closing of the second water inlet by using the second water inlet valve.

[0072] Further, the cleaning system further includes a second recovery bin, a third water inlet, and a second water outlet. The second water outlet is provided on the side wall and / or the top of the body 1, the third water inlet is opened at the bottom of the body 1, and the second water outlet, the third water inlet and the second recovery bin are respectively connected through.

[0073] In some preferred embodiments of the present invention, the cleaning system includes an independent first recovery bin 11 and a second recovery bin, so that the cleaning system has two independent recovery channels. The first recovery channel is: the first water inlet 13 - the first recovery bin 11 - the first water outlet; the second recovery channel is: the third water inlet - the second recovery bin - the second water outlet; by setting two independent recovery channels, the risk that the recovery channel is blocked and the pool cannot be effectively cleaned can be reduced accordingly.

[0074] Among them, when the second water outlet is provided on the side wall of the body, the body can obtain a corresponding thrust during the process of draining water to the outside of the body through the second water outlet, which is more beneficial to the movement of the body in the water; when the second water outlet is provided on the top of the body, when the body is in the state of sinking to the bottom of the pool, the second water outlet drains water upward at the top of the pool, and the drainage water flow of the second water outlet generates a downward acting force on the body, so that the body 1 moves more closely to the bottom of the pool; of course, in some preferred embodiments of the present invention, the operator can respectively open the second water outlet on the side wall and the top of the body.

[0075] The present invention also discloses a method for cleaning a pool robot, which is applied to the above-mentioned pool robot and includes the following steps:

[0076] Place the pool robot on the water surface of the pool and control the pool robot to execute the water surface cleaning mode or the bottom cleaning mode;

[0077] When the pool robot executes the water surface cleaning mode, the diving system 5 controls the body 1 to float on the water surface of the pool, and the cleaning system cleans the floating objects floating on the water surface of the pool;

[0078] When the pool robot executes the bottom cleaning mode, the diving system 5 controls the body 1 to sink to the bottom of the pool, and the cleaning system cleans the sediment at the bottom of the pool.

[0079] Further, the diving system 5 controls the main body 1 to float on the pool water surface, and the cleaning system cleans the floating objects on the pool water surface. Specifically: the air inlet valve 9 of the diving system 5 is opened, and the water tank 6 is filled with air; the main body 1 moves on the water surface, and the water in the pool flows into the first recovery bin 11 from the first water inlet 13. The first recovery bin 11 filters the floating objects on the pool water surface and discharges the water from the first water outlet.

[0080] Further, when the pool robot executes the bottom cleaning mode, the diving system 5 controls the main body 1 to sink to the bottom of the pool, and the cleaning system cleans the sediment at the bottom of the pool. Specifically: the air outlet valve 10 and the water inlet pump 7 of the diving system 5 are opened, the air in the water tank 6 is discharged through the air outlet valve 10, the water inlet pump 7 injects water into the water tank 6, and the main body 1 sinks to the bottom of the pool; the water in the pool flows into the first recovery bin 11 from the second water inlet, and the first recovery bin 11 filters the sediment at the bottom of the pool and discharges the water from the first water outlet.
