[0030] See also Figures 1 to 3 , Figure 1 This is a schematic diagram of the three-dimensional structure of an embodiment of the pool cleaning robot of the present application; Figure 2 This is a schematic diagram of the three-dimensional structure of another embodiment of the pool cleaning robot of the present application; Figure 3 This is a schematic diagram of the bottom structure of another embodiment of the pool cleaning robot of the present application.

[0031] One embodiment of the present application provides a pool cleaning robot 10. The pool cleaning robot 10 includes a robot body 11, a cleaning assembly 12, and a moving mechanism 13. The cleaning assembly 12 includes at least a flow channel, a filter assembly, a sewage suction port 121, and a water spray assembly 122. The moving mechanism 13 is disposed on the robot body 11 and is used to drive the robot body 11 to move. The water spray assembly 122 is disposed on the robot body 11. The water spray assembly 122 is used to spray water toward the area to be cleaned, thereby at least flushing the area to be cleaned or guiding at least some of the garbage in the area to be cleaned to the working area of ​​the sewage suction port 121.

[0032] As can be seen from the above structure, the robot body 11 can be used to provide a certain support for the cleaning component 12 and the moving mechanism 13. The cleaning component 12 can be used to clean the area to be cleaned. Normally, the cleaning component 12 includes at least a flow channel (not shown in the figure), a filter component (not shown in the figure), a sewage suction port 121 and a water spray component 122. Specifically, in the process of the pool cleaning robot 10 cleaning the area to be cleaned, the sewage suction port 121 can suck in the sewage in the area to be cleaned, and filter out the garbage in the sewage through the filter component, and the filtered water can be discharged from the robot body 11 through the flow channel, thereby achieving the cleaning of the area to be cleaned. It can be understood that the water in the flow channel can be discharged through the set drain port on the robot body 11, or it can flow to the water spray component 122 to be sprayed out through the water spray component 122. The water spray assembly 122 can spray water toward the area to be cleaned. On the one hand, the impact of the water flow can flush and clean the area to be cleaned. On the other hand, due to the limitations of the pool cleaning robot 10's own structure and the position limitations of the sewage suction port 121, the pool cleaning robot 10 may not be able to clean garbage in specific areas such as the corners of the pool. Therefore, the water sprayed by the water spray assembly 122 drives the garbage that was originally unable to be cleaned to move, allowing the pool cleaning robot 10 to clean the garbage, thereby increasing the cleaning range of the pool cleaning robot 10 and further improving the cleaning efficiency of the pool cleaning robot 10. It is understandable that the water of the water spray assembly 122 can come from the aforementioned flow channel, or other components in the robot body 11, or can be extracted from the outside of the robot body 11, which is not limited here.

[0033] The mobile mechanism 13 can drive the robot body 11 to move within the pool, such as on the water surface, in the water, or at the bottom of the pool. The mobile mechanism 13 can realize the movable cleaning of the pool cleaning robot 10. The area to be cleaned can be any area within the pool. Specifically, the area to be cleaned can include at least one of the water area between the robot body 11 and the pool wall and the pool wall. Alternatively, the area to be cleaned also includes the working area of ​​the sewage suction port 121, wherein the working area of ​​the sewage suction port 121 is the coverage area of ​​the sewage suction port 121, or the radiation area extending to the sewage suction port 121 due to the suction force generated by the suction component in the robot 10, where the suction port 121 can produce a cleaning effect.

[0034] The mobile mechanism 13 may include at least one of a travel assembly and a pusher. The travel assembly may be a track, roller, or the like. When the mobile mechanism 13 includes a travel assembly, the mobile mechanism 13 may also include a power source, such as a motor, to drive the travel assembly. Specifically, when the pool cleaning robot 10 moves across the bottom of the pool, the power source may drive the travel assembly to enable the pool cleaning robot 10 to move across the pool bottom. Optionally, the pool wall includes pool wall corners, a bottom wall, and pool sidewalls. Pool wall corners include corners between the bottom wall and sidewalls, as well as corners between adjacent sidewalls.

[0035] It should be noted that the sewage suction port 121 can be set at the bottom of the robot body 11, or the sewage suction port 121 can also be set at the front side, top, etc. of the robot body 11. When the sewage suction port 121 is set at the bottom of the robot body 11, at this time, the sewage suction port 121 can be specifically set at a position near the front side of the bottom of the robot body 11. By setting the sewage suction port 121 at a position near the front side of the bottom of the robot body 11, or setting it at the front side of the robot body 11, or setting the sewage suction port 121 at the top of the robot body 11, at this time, the distance between the area to be cleaned and the sewage suction port 121 can be shortened, so that the garbage in the area to be cleaned can be quickly sucked into the sewage suction port 121, thereby improving the overall cleaning efficiency.

[0036] In one embodiment of the present application, the water spray assembly 122 is provided with one or more nozzles 123 to spray water through the nozzles 123. Specifically, the nozzles 123 of the water spray assembly 122 can be provided at the edge of the robot body 11. The nozzles 123 spray water toward the side or front of the robot body 11.

[0037] The water flow ejected from the nozzle 123 can drive the garbage to move by at least one of forming disturbances, pool wall reflection, water flow guidance, etc., and then bring the garbage to the area that the pool cleaning robot 10 can clean. For example, the area that the pool cleaning robot 10 can clean includes the working area of ​​the sewage suction port 121, so that the sewage suction port 121 can suck the garbage into the sewage suction port 121.

[0038] In one embodiment, when the pool cleaning robot 10 approaches the edge of the pool, for example, when the pool cleaning robot 10 moves along the edge of the pool via the moving mechanism 13, at least one nozzle 123 sprays water toward the pool wall (for example, by spraying water toward the side or front of the robot body 11 so that the water is sprayed toward the pool wall). Thus, the nozzle 123 sprays water toward the pool wall to flush the pool wall, and the reflection of the water by the pool wall pushes garbage on the pool wall and garbage between the pool wall and the robot body 11 toward the pool cleaning robot 10, allowing the pool cleaning robot 10 to suck the garbage through the sewage suction port 121, thereby improving overall cleaning efficiency. Furthermore, when the nozzle 123 sprays water toward the pool wall, the disturbance created by the water sprayed by the nozzle 123 can also have a certain gathering effect on the garbage, further facilitating the suction of the garbage by the sewage suction port 121, thereby improving cleaning efficiency. Therefore, the nozzle 123 sprays water toward the pool wall, which can not only flush and clean the pool wall, but also gather the garbage, gathering at least part of the garbage to the working area of ​​the sewage suction port 121, thereby improving the overall cleaning efficiency.

[0039] In another specific embodiment, when the pool cleaning robot 10 is located in the pool, for example, when the pool cleaning robot 10 moves in the pool through the moving mechanism 13, at least one nozzle 123 can spray water to the side and / or front of the robot body 11. At this time, the nozzle 123 sprays water to form a disturbance, so that the garbage can be brought into the working area of ​​the sewage suction port 121. For example, when the pool cleaning robot 10 moves in the pool, the working area of ​​the sewage suction port 121 can be the area on the moving path of the pool cleaning robot 10 that can be covered by the suction force of the sewage suction port 121. The nozzle 123 can spray water in front of the robot body 11 to form a disturbance of the water body, and push at least part of the garbage originally outside the working area of ​​the sewage suction port 121 that is affected by the disturbance to the working area of ​​the sewage suction port 121, so that the sewage suction port 121 can suck in the garbage, expand the cleaning range of the pool cleaning robot 10, and thus improve the overall cleaning efficiency.

[0040] Optionally, when the water flow at the nozzle 123 forms a disturbance to drive the garbage closer to the working area of ​​the sewage suction port 121, the pool cleaning robot 10 further includes a water retaining structure 14. The water retaining structure 14 is arranged on the water flow path of the jetting water flow. At this time, on the one hand, the water retaining structure 14 can block the part of the jetting water flow with a faster flow rate to prevent the garbage from being pushed away from the pool cleaning robot 10 by this part of the water flow, thereby causing some garbage to be unable to be sucked into the sewage suction port 121; on the other hand, the water retaining structure 14 can change the flow direction of the jetting water flow to form a water flow disturbance suitable for gathering floating garbage outside the cleaning range of the sewage suction port 121 into the cleaning range. Therefore, the provision of the water retaining structure 14 can improve the cleaning effect of garbage on and near the travel path of the pool cleaning robot 10, thereby improving the user's cleaning experience.

[0041] In another embodiment, the nozzle 123 of the water spray assembly 122 can spray water toward the sewage suction port 121, thereby guiding the waste into the working area of ​​the sewage suction port 121. For example, the nozzle 123 of the water spray assembly 122 can be disposed on the exterior of the robot body 11, with the sewage suction port 121 located at the front of the robot body 11. When the nozzle 123 is in operation, the nozzle 123 is directed toward the sewage suction port 121 to spray water toward the sewage suction port 121. The water sprayed from the nozzle 123 can gather the waste, thereby concentrating it within the working area of ​​the sewage suction port 121. The distance between the gathered waste and the sewage suction port 121 is shortened, making waste suction by the sewage suction port 121 more labor-saving, efficient, and quick. Furthermore, the water can push waste originally outside the working area of ​​the sewage suction port 121 into the working area of ​​the sewage suction port 121, thereby expanding the cleaning range of the pool cleaning robot 10 and improving overall waste suction efficiency.

[0042] In one embodiment, the position of the nozzle 123 may include a first position and a second position. The nozzle 123 moves between the first position and the second position. For example, the nozzle 123 can rotate between the first position and the second position around an axis in a specific direction, such as a horizontal direction, a vertical direction, etc. The first position is the position where the nozzle 123 sprays water toward the sewage suction port 121, that is, when the nozzle 123 needs to spray water toward the sewage suction port 121, it moves to the first position to spray water. The second position is a position different from the first position. For example, when the nozzle 123 can rotate in the vertical direction, if the first position is above the robot body 11, the second position may be below the robot body 11. For details, please refer to Figures 4 and 5For example, the nozzle 123 can rotate horizontally around the robot body 11, with the first position being away from the robot body 11 and the second position being close to the robot body 11. When the nozzle 123 does not need to spray water toward the sewage suction port 121, the nozzle 123 is located in the second position. When the nozzle 123 needs to spray water toward the sewage suction port 121, the nozzle 123 rotates to the first position so that the nozzle 123 faces the sewage suction port 121 and sprays water toward the sewage suction port 121. At this time, the water sprayed by the nozzle 123 can have a certain gathering effect on the garbage, thereby gathering the garbage into the working area of ​​the sewage suction port 121, so that the sewage suction port 121 can absorb the garbage. In addition, the nozzle 123 can be movably arranged. For example, the nozzle 123 can be recovered to the robot body 11 when the nozzle 123 is not working, so as to avoid the nozzle 123 interfering with the work of the pool cleaning robot 10 when it is not needed to work; when the nozzle 123 needs to spray water in other directions besides the suction port 121, the nozzle 123 can be moved to the second position and spray water, without the need to set up multiple nozzles 123.

[0043] In a specific embodiment, the water spray assembly 122 may include a water spray member 124 and a power unit (not shown in the figure). Among them, the nozzle 123 is provided on the water spray member 124. The power unit is used to drive the nozzle 123 of the water spray member 124 to spray water. It can be a device originally provided on the pool cleaning robot 10, such as a main water pump, etc., or it can be a newly added device, such as a newly added water pump, plunger pump, diaphragm pump, etc. The power unit is used to provide power for the nozzle 123 to spray water. A single nozzle 123 can correspond to a single power unit, or multiple nozzles 123 can correspond to the same power unit. The water spray member 124 can be a water spray rod, or it can be other forms. The form of the water spray member 124 is not limited here.

[0044] Optionally, the above-mentioned water spraying member 124 can be one or more. Each water spraying member 124 is provided with one or more nozzles 123. Among them, different water spraying members 124 can work simultaneously or individually, and different nozzles 123 on the same water spraying member 124 can also work simultaneously or individually. In the specific scenario of using the nozzle 123 to clean the area to be cleaned, it is necessary to consider the current position and orientation of the nozzle 123 to see whether it can spray water to the area to be cleaned. Therefore, it is necessary to perform corresponding operations before the water spray cleaning so that the working nozzle 123 can spray water to the area to be cleaned. The specific operation can be to move / rotate the nozzle 123 to be worked, or select the nozzle 123 with the corresponding position and orientation from the multiple nozzles 123 of the water spraying member 124 as the nozzle 123 to be worked, or select the water spraying member 124 with the corresponding position and orientation of the nozzle 123 from the multiple water spraying members 124, so that the nozzle 123 with the corresponding position and orientation on the water spraying member 124 is used as the nozzle 123 to be worked.

[0045] Specifically, when there is only one water spraying member 124, the current posture capable of cleaning the area to be cleaned is set as the target posture, which may include a target orientation and / or a target position, the target position being, for example, the distance from the bottom of the pool, or the distance from the robot body 11. The posture of the nozzle 123 on the water spraying member 124 can be adjusted, for example, it can be rotated to adjust the orientation and / or can be moved along a set direction (such as a direction close to or away from the bottom of the pool, a direction close to or away from the robot body 11) to adjust the target position. In one example, the nozzle 123 on the water spraying member is rotatable, and the pool cleaning robot 10 further includes an adjustment mechanism (not shown in the figure), which rotates the nozzle 123 of the water spraying member 124 through the adjustment mechanism so that the orientation of the nozzle 123 is the target orientation. In another example, the nozzle 123 on the water spraying member 124 is not rotatable. Since the relative position between the nozzle 123 and the robot body 11 is fixed, the position of the nozzle 123 can be changed by adjusting the angle of the robot body 11, thereby adjusting the direction of the nozzle 123 to the target direction. For example, if the target direction of the nozzle 123 is parallel to the water surface, the nozzle 123 is set at the side edge of the robot body 11 and faces the front and upper part of the robot body 11, then the angle of the robot body 11 can be adjusted so that the head of the pool cleaning robot 10 is facing downward and the tail is tilted, thereby adjusting the direction of the nozzle 123 to the target direction. The target direction can be determined by the posture of the pool cleaning robot 10. For example, the pool cleaning robot 10 includes a first posture and a second posture. The first posture includes a surface posture, which requires the nozzle 123 to be able to guide garbage near the waterline of the pool wall or the corner of the adjacent pool wall to the cleaning path of the pool cleaning robot 10 as much as possible when spraying water in the target direction; the second posture includes an underwater posture, which requires the nozzle 123 to be able to clean or guide garbage near the pool bottom or pool wall or the junction of the pool bottom and pool wall when spraying water in the target direction. For the first posture, the currently working nozzle 123 is required to be set at a position on the robot body 11 close to the water surface; for the second posture, the currently working nozzle 123 is required to be set on the robot body 11 and facing the pool bottom or pool wall, or tilted toward the junction of the pool bottom and pool wall.

[0046] When there are multiple water spraying components 124, the nozzles 123 on each water spraying component 124 have different postures. The postures may include orientation and / or position, such as the distance from the pool bottom or the distance from the robot body 11. In one example, at least one water spraying component 124 can be selected for operation based on the posture of the pool cleaning robot 10. For example, a target orientation can be determined based on the posture of the pool cleaning robot 10, and the nozzle 123 with the target orientation can be selected for operation. The relationship between the target orientation and the posture of the pool cleaning robot 10 can be as described in the example above. For another example, a target position can be determined based on the posture of the pool cleaning robot 10, and the nozzle 123 located at the target position can be selected for operation. Specifically, the multiple water spraying components 124 can be arranged on both sides or on a single side of the robot body 11. For example, the multiple water spraying components 124 can be arranged on the left and right sides of the robot body 11, with at least one water spraying component 124 on each side, and the nozzles 123 of the water spraying components 124 on both sides have different orientations. For another example, the multiple water spraying members 124 are all located on the same side of the robot body 11, such as the front or right side, and the nozzles 123 on the multiple water spraying members 124 are all oriented in different directions. Thus, the water spraying member 124 with the nozzle 123 that matches the posture of the pool cleaning robot 10 can be selected for water spraying.

[0047] In a specific application scenario, two water spraying parts 124 are provided on both sides of the pool cleaning robot 10. The two water spraying parts 124 on each side are an upper water spraying part and a lower water spraying part. Correspondingly, the nozzle 123 of the upper water spraying part is an upper nozzle, and the nozzle 123 of the lower water spraying part is a lower nozzle. The upper nozzle and the lower nozzle are oriented directly forward or have a certain outward angle with respect to the forward direction. For example, when the pool cleaning robot 10 is in a surface posture, the upper nozzles on both sides are selected to work to clean the pool wall at the waterline. When the pool cleaning robot 10 is in an underwater posture, the lower nozzles on both sides are selected to work to clean the bottom wall of the pool.

[0048] Alternatively, the power unit may be a propeller (not shown in the figure). For example, the propeller may be set as a single propeller, and the single propeller may be connected to any water spraying member 124 respectively; the propeller may also be set as a multi-propeller, such as a dual propeller, and the dual propeller may be connected to the corresponding side water spraying member 124 respectively, or only the predetermined side propeller of the dual propeller may be connected to the water spraying member 124. The propeller is reversed, and thus the water flow can be delivered to the front side of the robot body 11, so that the water flow can be ejected from the nozzle 123 of the water spraying member 124. In a specific application scenario, the propeller may also be the propeller in the moving mechanism 13, that is, the propeller is also used to drive the robot body 11 to move. When the robot body 11 needs to adjust the direction of movement, the rotation direction of the propeller on the side away from the wall can be adjusted, for example, from reverse rotation to forward rotation, and the direction of the robot can be adjusted. Optionally, in order to prevent the pool cleaning robot 10 from moving backward due to the reversal of the propeller, other power units, such as the main water pump, travel components and other power devices, can be retained, and the power of the propeller reversal can be adjusted so that the forward propulsion force of other power units is greater than or equal to the propulsion force of the propeller flipping, thereby allowing the pool cleaning robot 10 to move forward or stay in place, reducing the impact on the work of the pool cleaning robot 10.

[0049] Optionally, the power unit may also be a pump body for driving the pool cleaning robot to float or sink. Figures 1 to 6 , Figure 6 It is a schematic diagram of the internal structure of a pool cleaning robot according to an embodiment of the present application.

[0050] The pool cleaning robot 10 also includes a float chamber 15 and a pump body 16. The float chamber 15 may be at least partially located within the robot body 11. The pump body 16 is disposed within the robot body 11 and is used to extract water from the float chamber 15 or to draw water into the float chamber 15. When the pump body 16 draws water from the float chamber 15, the amount of water in the float chamber 15 decreases and the amount of air increases, thereby reducing the weight of the pool cleaning robot 10 and allowing it to float upward. When the pump body 16 draws water into the float chamber 15, the amount of water in the float chamber 15 increases and the amount of air decreases, thereby increasing the weight of the pool cleaning robot 10 and allowing it to sink downward. The pool cleaning robot 10 can also control the speed and height of its ascent / descent by controlling the amount of water drawn in or drawn in.

[0051] In this embodiment, the power unit is a pump body 16. The robot body 11 is provided with a drain port 111, and the pump body 16 is connected to the drain port 111. The robot body 11 also includes a control valve 112. The pump body 16 is connected to the drain port 111 and the control valve 112. The control valve 112 is also connected to the water spray assembly 122 and the float chamber 15. Thus, when the pool cleaning robot 10 is in the pool and the drain port 111 of the pool cleaning robot 10 is located below the waterline of the pool, when the water spray assembly 122 needs to work, the control valve 112 can control the drain port 111 to be connected with the water spray assembly 122, and the pump body 16 sucks external water from the drain port 111 and sprays water through the nozzle 123 of the water spray assembly 122; when the pool cleaning robot 10 needs to adjust its posture, the control valve 112 can control the drain port 111 to be connected with the float chamber 15, and the pump body 16 sucks external water from the drain port 111 into the float chamber 15 to achieve sinking, or draws out the water in the float chamber 15 through the drain port 111 to achieve floating.

[0052] Specifically, when the pool cleaning robot 10 is in a water surface posture to clean the water surface, the control valve 112 opens the communication channel between the nozzle 123 and the drain port 111, and closes the communication channel between the float chamber 15 and the drain port 111. The pump body 16 sucks external water from the drain port 111 and sprays water through the nozzle 123 of the water spray assembly 122 to clean the area to be cleaned on the water surface.

[0053] When the pool cleaning robot 10 needs to clean the water in the water, the control valve 112 closes the communication channel between the nozzle 123 and the drain port 111, opens the communication channel between the float chamber 15 and the drain port 111, and the pump body 16 draws external water from the drain port 111 into the float chamber 15, so that the buoyancy of the pool cleaning robot 10 is less than the gravity, and the pool cleaning robot 10 sinks into the water to switch to an underwater posture. When the pool cleaning robot 10 sinks to a target location in the water, such as the bottom of the pool or a specific height in the water, the control valve 112 opens the communication channel between the nozzle 123 and the drain port 111, closes or maintains the communication channel between the float chamber 15 and the drain port 111, and the pump body 16 draws external water from the drain port 111 and sprays water through the nozzle 123 of the water spray assembly 122 to clean the area to be cleaned in the water, such as the bottom wall or side wall of the pool.

[0054] When the pool cleaning robot 10 needs to switch back to the water surface posture, the control valve 112 closes the communication channel between the nozzle 123 and the drain port 111, opens the communication channel between the float chamber 15 and the drain port 111, and the pump body 16 discharges the water in the float chamber 15 from the drain port 111, so that the buoyancy currently exerted on the pool cleaning robot 10 is greater than the gravity it is subjected to, and then floats to the water surface to switch to the water surface posture.

[0055] It can be understood that the control valve 112 serves as a communication control component between the nozzle 123, the drain port 111 and the float chamber 15. It can not only control the communication between the nozzle 123 or the float chamber 15 and the drain port 111, but also control the communication between the nozzle 123 and the float chamber 15, so that the pump body 16 can spray the water in the float chamber 15 out of the nozzle 123, so the operation of the nozzle 123 can also be realized. However, at this time, the gravity of the pool cleaning robot 10 becomes smaller due to the reduction in the amount of water in the float chamber 15, so the position of the pool cleaning robot 10 may change, such as floating up, due to the change in the total force acting on the pool cleaning robot 10.

[0056] In another specific embodiment, the pool cleaning robot 10 also includes the float chamber 15 and pump body 16 described above, with the pump body 16 serving as the power unit. However, the robot body 11 does not include the control valve 112. Instead, the float chamber 15 is directly connected to the nozzle 123 of the water spray assembly 122. When the nozzle 123 is activated, the pump body 16 pumps water out of the float chamber 15 and sprays it out of the nozzle 123. It will be appreciated that, as described above, a decrease in the amount of water in the float chamber 15 may cause the position of the pool cleaning robot 10 to change, such as causing it to float upward. Therefore, if the position of the pool cleaning robot 10 is not desired, the pump body 16 or another pump body can also draw external water from the drainage port of the robot body 11 into the float chamber 15 to maintain a relatively small amount of water in the float chamber 15.

[0057] Therefore, by reusing the pump body 16 that controls the floating and sinking of the pool cleaning robot 10 as the power source for the nozzle 123 to spray water, there is no need to set up additional power mechanisms to make the nozzle 123 of the water spraying part 124 spray water, thereby effectively saving the number of structural parts and reducing production costs, and at the same time, it can also effectively reduce the overall volume of the pool cleaning robot 10.

[0058] It should be noted that, in the embodiment of the present application, the pump body 16 is a peristaltic pump. Of course, in some other embodiments, the pump body 16 may also adopt other power structures, which is not limited here.

[0059] Optionally, the water surface posture can be a water surface cleaning posture. In a specific embodiment, when the pool cleaning robot 10 is in the water surface cleaning posture, at least the currently active nozzle 123 is required to be located at a position of the robot body 11 close to the water surface. At this time, the water flow ejected through the nozzle 123 can then be used to clean the water surface and the pool wall at the waterline. At the same time, the pool cleaning robot 10 can also move forward on the water surface under the action of the moving mechanism 13, thereby enabling the pool cleaning robot 10 to achieve mobile cleaning of the water surface.

[0060] Furthermore, the underwater posture can be an underwater cleaning posture or an underwater cleaning posture. In one specific embodiment, the pool cleaning robot 10 is in an underwater cleaning posture, that is, the pool cleaning robot 10 is in a cleaning posture at a specific height in the water. At this time, at least one nozzle 123 currently in operation is provided on the robot body 11 and is oriented toward the pool bottom. In this case, water is ejected through the nozzle 123 to clean fine impurities at a specific height in the water and to clean the pool sidewalls at a specific height. When the pool cleaning robot 10 is in the underwater cleaning posture, at least one nozzle 123 currently in operation is provided on the robot body 11 and is oriented toward the pool bottom. Water can be ejected through the nozzle 123 to clean the pool bottom wall and the corners between the pool bottom wall and the sidewalls. The movement of the pool cleaning robot 10 in the water and underwater can be achieved by the mobile mechanism 13, thereby enabling the mobile cleaning of the pool cleaning robot 10. The moving mechanisms 13 corresponding to the pool cleaning robot 10 moving in the first posture and the second posture may be the same or different.

[0061] The following describes the workflow of the pool cleaning robot 10 performing cleaning operations: First, the pool cleaning robot 10 receives a cleaning instruction, wherein the cleaning instruction includes controlling the pool cleaning robot 10 to be in a first posture or a second posture. At this time, the user can send the cleaning instruction via a remote control to determine the posture of the pool cleaning robot 10, or can control it via an electronic device such as a mobile phone, or operate the pool cleaning robot 10 through buttons on the robot itself. Of course, other methods are also possible for control.

[0062] Secondly, the pool cleaning robot 10 controls its mobile structure to drive the robot body 11 to move to the area to be cleaned to perform cleaning work according to the cleaning instruction, and controls the operation of the water spray component 122 according to the posture of the pool cleaning robot. That is, when the pool cleaning robot 10 is in a first posture, at least the nozzle 123 provided on the robot body 11 near the water surface is controlled to spray water, at this time, the water surface and the corners between the water surface and the side walls of the pool can be cleaned. When the pool cleaning robot 10 is in a second posture, at least the nozzle 123 provided on the robot body 11 and directed toward the pool bottom is controlled to spray water, at this time, the bottom wall of the pool and the corners between the bottom wall and the side walls of the pool can be cleaned.

[0063] It should be noted that, whether the pool cleaning robot 10 is in the first posture or the second posture, the pool cleaning robot 10 can clean the area to be cleaned according to a predetermined route, wherein the predetermined route can be an I-shaped, or a U-shaped, etc., which is not limited here. In addition, when the pool cleaning robot 10 cleans according to the predetermined route, its cleaning times can be a preset cleaning times, that is, the pool cleaning robot 10 cleans the predetermined cleaning times according to the predetermined route. The preset number of times can be 2 times, 3 times, or 5 times, which is not limited here. By having the pool cleaning robot 10 clean the predetermined cleaning times according to the predetermined route, at this time, on the one hand, the overall cleaning efficiency can be improved, and on the other hand, the uniformity of cleaning the water surface or the side walls of the pool and the bottom wall of the pool can also be improved.

[0064] Of course, in some other embodiments, the pool cleaning robot 10 may not need to clean according to a predetermined route and for a predetermined number of times, which is not limited here.

[0065] By controlling the pool cleaning robot 10 of the present application, the pool cleaning robot 10 can clean specific areas that are restricted by its own structure and the position of the sewage suction port 121, such as garbage in the corners of the pool, regardless of whether it is in the first posture or the second posture. This can greatly expand the overall cleaning range and thus improve the overall cleaning efficiency. In addition, different directions of the nozzle 123 can be set according to different postures, thereby improving the targeted cleaning of the pool cleaning robot 10 and improving the cleaning effect. The control method is simple, the user is easy to operate, and the user experience is also better.
