Description

Technical Field

[0001] This application relates to the field of pool cleaning machine technology, and in particular to a water outlet structure with optimized steering function and a fully automatic pool cleaning machine. Background Technology

[0002] Existing pool cleaning machines, whether equipped with centrifugal pumps or axial flow pumps, often incorporate a first deflector in the drainage channel to ensure comprehensive pool cleaning and maximize the cleaning area. When the machine turns, the angle between the water-facing side of the first deflector and the flow cross-section in the drainage channel is acute (angle 1), while the angle between the water-repellent side of the first deflector and the flow cross-section in the drainage channel is obtuse (angle 2). Thus, the water, after passing through the power unit and the inlet channel, enters the drainage channel. Guided by the first deflector in the drainage channel, the water flows obliquely to one side of the pool cleaning machine, specifically from the space within the acute angle between the first deflector and the flow cross-section. This causes the pool cleaning machine to turn and expand the cleaning area, for example, by turning in a "Z" shape. This turning and walking technology is present in both pool cleaning machines equipped with centrifugal and axial flow pumps.

[0003] However, there is a problem: whether it is a pool cleaner with a centrifugal pump or a pool cleaner with an axial flow pump, there is often a situation where the steering is malfunctioning, that is, the steering angle of the pool cleaner is extremely small or even zero. An extremely small steering angle of the pool cleaner will increase the time required to clean the pool thoroughly, while a zero steering angle will result in the pool only moving straight even after a long time, and the pool will not be thoroughly cleaned. Summary of the Invention

[0004] To prevent the swimming pool cleaning machine from malfunctioning, this application provides a fully automatic swimming pool cleaning machine with an irregularly shaped water flow channel, employing the following technical solution:

[0005] An optimized water outlet structure with steering function includes an inlet channel, a drain channel, and a steering device. The inlet channel and the drain channel are connected. The steering device includes a first steering plate connected to the drain channel. When the pool cleaning machine turns, the angle between the side of the first steering plate facing the water inlet channel and the cross-section of the water flow in the drain channel is an acute angle, and the angle between the side of the first steering plate away from the water inlet channel and the cross-section of the water flow in the drain channel is an obtuse angle. The device also includes an end face, which is located at the connection between the inlet channel and the drain channel or inside the drain channel. The end face faces the outlet of the drain channel. When the pool cleaning machine turns, the rear side of the first steering plate facing the end face approaches or contacts the end face.

[0006] When the pool cleaning machine turns and moves, the rear side of the first steering plate facing the end face contacts the end face. The way the rear side of the first steering plate facing the end face contacts the end face is that more than half of the rear side of the first steering plate facing the end face is in contact with the end face.

[0007] When the pool cleaning machine turns and moves, the rear side of the first steering plate facing the end face contacts the end face. The way the rear side of the first steering plate facing the end face contacts the end face is that all parts of the rear side of the first steering plate facing the end face are completely in contact with the end face.

[0008] When the pool cleaning machine turns and moves, the first steering plate faces the lower side of the drainage channel and approaches or fits against the drainage channel.

[0009] When the pool cleaning machine turns and moves, the first steering plate faces the upper side of the drainage channel and approaches or fits against the drainage channel.

[0010] The first steering plate is rotatably connected to the drainage channel. When the pool cleaning machine turns and moves, the first steering plate rotates to the rear side of the first steering plate facing the end face, which is close to or in contact with the end face. When the pool cleaning machine moves straight, the first steering plate rotates to the position where the first steering plate is perpendicular to the flow section.

[0011] The steering device also includes a second steering plate, which is parallel to the first steering plate and is connected to the drainage channel.

[0012] The steering device also includes a second steering plate, which is parallel to the first steering plate and is rotatably connected to the drainage channel. When the pool cleaning machine turns and moves, the first steering plate rotates to the rear side of the first steering plate facing the end face, which is close to or in contact with the end face, and the second steering plate is parallel to the first steering plate. When the pool cleaning machine moves straight, the first steering plate rotates to the position where the first steering plate is perpendicular to the flow section, and the second steering plate is parallel to the first steering plate.

[0013] The steering device also includes a linkage block, which has a first linkage hole and a second linkage hole. The steering device also includes a first linkage column and a second linkage column. The first linkage column is fixedly connected to the upper side of the first steering plate facing the drainage channel, and the second linkage column is fixedly connected to the upper side of the second steering plate facing the drainage channel. The first linkage column is inserted into the first linkage hole of the linkage block, and the second linkage column is inserted into the second linkage hole of the linkage block. The first linkage column can rotate in the first linkage hole, and the second linkage column can rotate in the second linkage hole.

[0014] A fully automatic swimming pool cleaning machine includes a power unit and an impeller, and includes a water outlet structure with any of the above-described steering functions optimized.

[0015] In summary, this application includes at least one of the following beneficial effects:

[0016] 1) After discovering the cause of the swimming pool cleaning machine's steering failure, this application adopted some technical measures. The rear side of the first steering plate facing the end face is close to or in contact with the end face. This reduces the gap between the rear side of the first steering plate facing the end face and the end face, reduces the water flow from the space in the obtuse angle between the first steering plate and the flow section, and also reduces the water flow from the rear of the swimming pool cleaning machine in the opposite direction of forward movement. This increases the water flow from the acute angle between the first steering plate and the flow section, making it more conducive for the water flow to flow obliquely to one side of the swimming pool cleaning machine under the guidance of the first steering plate in the drainage channel. This further facilitates the turning and movement of the swimming pool cleaning machine, optimizes the steering function, and improves the swimming pool cleaning machine's ability to thoroughly clean the swimming pool.

[0017] 2) More than half of the rear side of the first steering plate facing the end face is in contact with the end face. There is no gap between the part of the rear side of the first steering plate facing the end face and the end face, which further reduces the gap between the rear side of the first steering plate facing the end face and the end face. This reduces the water flow from the space where the first steering plate and the flow section form an obtuse angle (two). The water flow from the rear of the pool cleaning machine in the opposite direction of forward movement is also reduced. This increases the water flow from the space where the first steering plate and the flow section form an acute angle (one). This makes it easier for the water to flow obliquely to one side of the pool cleaning machine under the guidance of the first steering plate in the drainage channel. This further facilitates the turning and walking of the pool cleaning machine, optimizes the turning function, and improves the ability of the pool cleaning machine to clean the pool comprehensively.

[0018] 3) All parts of the rear side of the first steering plate facing the end face are completely in contact with the end face. There are no gaps between all parts of the rear side of the first steering plate facing the end face and the end face. No water flows out from the space where the first steering plate and the flow section form an obtuse angle (angle 2) in the drainage channel. This further reduces the water flow out from the space where the first steering plate and the flow section form an obtuse angle (angle 2). The water flow out from the rear of the pool cleaning machine in the opposite direction of forward movement is also reduced. This increases the water flow out from the space where the first steering plate and the flow section form an acute angle (angle 1). This makes it easier for the water to flow obliquely to one side of the pool cleaning machine under the guidance of the first steering plate in the drainage channel. This further facilitates the turning and movement of the pool cleaning machine, optimizes the turning function, and improves the pool cleaning machine's ability to thoroughly clean the pool.

[0038] The following is in conjunction with the appendix Figure 1-18 This application will be described in further detail. It should be noted that although only an illustration of a pool cleaning machine with an axial flow pump is provided in this application, the technology described herein is equally applicable to pool cleaning machines with centrifugal pumps.

[0039] like Figure 1-18 A water outlet structure with optimized steering function includes an inlet channel 1, a drain channel 2, and a steering device. The inlet channel 1 and the drain channel 2 are connected. The steering device includes a first steering plate 3 connected in the drain channel 2. When the pool cleaning machine turns, the angle between the water-facing side 4 of the first steering plate 3 facing the inlet channel 1 and the cross-section of the water flow in the drain channel 2 is an acute angle, and the angle between the water-repellent side 6 of the first steering plate 3 away from the inlet channel 1 and the cross-section of the water flow in the drain channel 2 is an obtuse angle. The device also includes an end face 7, which is located at the connection between the inlet channel 1 and the drain channel 2 or inside the drain channel 2. The end face 7 faces the outlet 10 of the drain channel. When the pool cleaning machine turns, the rear side 8 of the first steering plate 3 facing the end face 7 approaches or contacts the end face 7.

[0040] Existing pool cleaning machines, whether equipped with centrifugal pumps or axial flow pumps, often incorporate a first deflector plate 3 in the drainage channel 2 to ensure comprehensive pool cleaning and expand the cleaning area. When the pool cleaning machine turns, the angle between the water-facing side 4 of the first deflector plate 3 facing the inlet channel 1 and the flow section of the water in the drainage channel 2 is acute, while the angle between the water-repellent side 6 of the first deflector plate 3 away from the inlet channel 1 and the flow section of the water in the drainage channel 2 is obtuse. Thus, the water flowing through the power unit 11 and then through the inlet channel 1 enters the drainage channel 2. Guided by the first deflector plate 3 in the drainage channel 2, the water flows obliquely to one side of the pool cleaning machine. That is, the water flowing out from the space within the acute angle between the first deflector plate 3 and the flow section flows obliquely to one side of the pool cleaning machine, allowing the pool cleaning machine to turn and expand the cleaning area, for example, by turning in a "Z" shape. This steering and walking technology is available in pool cleaning machines equipped with centrifugal and axial flow pumps.

[0041] However, there is a problem: whether it is a pool cleaner with a centrifugal pump or a pool cleaner with an axial flow pump, there is often a situation where the steering is malfunctioning, that is, the steering angle of the pool cleaner is extremely small or even zero. An extremely small steering angle of the pool cleaner will increase the time required to clean the pool thoroughly, while a zero steering angle will result in the pool only moving straight even after a long time, and the pool will not be thoroughly cleaned.

[0042] The reason for the above-mentioned swimming pool cleaning machine steering failure was discovered in this application. After multiple tests and analyses, we found that the steering failure was due to a gap between the rear side 8 of the first steering plate 3 facing the end face 7 and the end face 7. A portion of the water flowed out from the space within the obtuse angle between the first steering plate 3 and the flow section. This portion of the water flow was not blocked by the first steering plate 3, and therefore did not flow obliquely to one side of the swimming pool cleaning machine, but instead flowed out towards the outlet 10 in the direction directly behind the forward direction of the swimming pool cleaning machine. This portion of the water flow did not play a role in prompting the swimming pool cleaning machine to turn.

[0043] In this application, "the rear side 8 of the first steering plate 3 facing the end face 7 is close to the end face 7" means that the distance between the rear side 8 of the first steering plate 3 facing the end face 7 and the end face 7 is very small but there is still a gap. "The rear side 8 of the first steering plate 3 facing the end face 7 is in contact with the end face 7" means that there is a contact point between the rear side 8 of the first steering plate 3 facing the end face 7 and the end face 7 without any gap.

[0044] After discovering the cause of the steering failure, some technical measures were taken. The rear side 8 of the first steering plate 3 facing the end face 7 was brought closer to or in contact with the end face 7. This reduced the gap between the rear side 8 of the first steering plate 3 facing the end face 7 and the end face 7, and reduced the water flow from the space in the obtuse angle between the first steering plate 3 and the flow section. The water flow in the direction directly behind the forward direction of the pool cleaning machine was also reduced, while the water flow from the acute angle between the first steering plate 3 and the flow section was increased. This made it easier for the water to flow obliquely to one side of the pool cleaning machine under the guidance of the first steering plate 3 in the drainage channel 2, which further facilitated the turning and walking of the pool cleaning machine, optimized the steering function, and improved the pool cleaning machine's ability to clean the pool comprehensively.

[0045] When the pool cleaning machine turns and moves, the rear side 8 of the first steering plate 3 facing the end face 7 contacts the end face 7. The way the rear side 8 of the first steering plate 3 facing the end face 7 contacts the end face 7 is that more than half of the rear side 8 of the first steering plate 3 facing the end face 7 is in contact with the end face 7.

[0046] "Applies to end face 7" means that the rear side 8 of the first steering plate 3 facing the end face 7 is in contact with the end face 7, and there is no gap between the rear side 8 of the first steering plate 3 facing the end face 7 and the end face 7.

[0047] In this way, there is no gap between the rear side 8 of the first steering plate 3 facing the end face 7 and the end face 7, further reducing the gap between the rear side 8 of the first steering plate 3 facing the end face 7 and the end face 7. This reduces the water flow from the space within the obtuse angle between the first steering plate 3 and the flow section, and also reduces the water flow directly behind the pool cleaner in the opposite direction of its forward movement. It increases the water flow from the acute angle between the first steering plate 3 and the flow section, making it more conducive for the water to flow obliquely to one side of the pool cleaner under the guidance of the first steering plate 3 in the drainage channel 2. This further facilitates the turning and movement of the pool cleaner, optimizes the turning function, and improves the pool cleaner's ability to thoroughly clean the pool.

[0048] When the pool cleaning machine turns and moves, the rear side 8 of the first steering plate 3 facing the end face 7 contacts the end face 7. The way the rear side 8 of the first steering plate 3 facing the end face 7 contacts the end face 7 is that all parts of the rear side 8 of the first steering plate 3 facing the end face 7 are completely in contact with the end face 7.

[0049] "Completely fits the end face 7" means that the rear side 8 of the first steering plate 3 facing the end face 7 is in surface-to-surface contact with the end face 7, and the rear side 8 of the first steering plate 3 facing the end face 7 is tightly pressed against the end face 7 without any gaps.

[0050] In this way, there is no longer any gap between the rear side 8 of the first steering plate 3 facing the end face 7 and the end face 7. The water flow entering the drainage channel 2 from the end face 7 is not allowed to flow out from the space where the first steering plate 3 and the flow section form an obtuse angle. This further reduces the water flow from the space where the first steering plate 3 and the flow section form an obtuse angle. The water flow flowing out from the rear of the pool cleaning machine in the opposite direction of forward movement is also reduced. This increases the water flow from the space where the first steering plate 3 and the flow section form an acute angle. This makes it easier for the water flow to flow obliquely to one side of the pool cleaning machine under the guidance of the first steering plate 3 in the drainage channel 2. This further facilitates the turning and walking of the pool cleaning machine, optimizes the turning function, and improves the ability of the pool cleaning machine to clean the pool comprehensively.

[0051] When the pool cleaning machine turns and moves, the first steering plate 3 faces the lower side 9 of the drainage channel 2 and approaches or fits against the drainage channel 2.

[0052] "Close to the drainage channel 2" means that there is a gap between the lower side 9 of the first steering plate 3 facing the drainage channel 2 and the drainage channel 2, but the gap is very small.

[0053] "Fitting into the drainage channel 2" means that the lower side 9 of the first steering plate 3 facing the drainage channel 2 is in surface-to-surface contact with the drainage channel 2, and there is no gap between the lower side 9 of the first steering plate 3 facing the drainage channel 2 and the drainage channel 2.

[0054] The lower side 9 of the first steering plate 3 facing the drainage channel 2 is close to the drainage channel 2, which reduces the gap between the lower side 9 of the first steering plate 3 facing the drainage channel 2 and the drainage channel 2. This reduces the water flow from the gap between the lower side 9 of the first steering plate 3 facing the drainage channel 2 and the drainage channel 2 into the space where the first steering plate 3 and the flow section form an obtuse angle (two). The water flow towards the rear of the pool cleaning machine in the opposite direction of forward movement is also reduced. This increases the water flow from the gap between the lower side 9 of the first steering plate 3 facing the drainage channel 2 and the drainage channel 2 into the space where the first steering plate 3 and the flow section form an acute angle (one). This makes it easier for the water to flow obliquely to one side of the pool cleaning machine under the guidance of the first steering plate 3 in the drainage channel 2, further improving the turning and movement of the pool cleaning machine, optimizing the turning function, and improving the pool cleaning machine's ability to thoroughly clean the pool.

[0055] The lower side 9 of the first steering plate 3 facing the drainage channel 2 is attached to the drainage channel 2. There is no gap between the lower side 9 of the first steering plate 3 facing the drainage channel 2 and the drainage channel 2. No water flows out from the gap between the lower side 9 of the first steering plate 3 facing the drainage channel 2 and the drainage channel 2 into the space where the first steering plate 3 and the flow section form an obtuse angle. No water flows out directly behind the pool cleaning machine in the opposite direction of its forward movement. This increases the water flow from the gap between the lower side 9 of the first steering plate 3 facing the drainage channel 2 and the drainage channel 2 into the space where the first steering plate 3 and the flow section form an acute angle. This makes it easier for the water to flow obliquely to one side of the pool cleaning machine under the guidance of the first steering plate 3 in the drainage channel 2. This further facilitates the turning and movement of the pool cleaning machine, optimizes the turning function, and improves the pool cleaning machine's ability to thoroughly clean the pool.

[0056] When the pool cleaning machine turns, the upper side 19 of the first steering plate 3 facing the drain channel 2 approaches or adheres to the drain channel 2. "Approaching the drain channel 2" means that there is a small gap between the upper side 19 of the first steering plate 3 and the drain channel 2, but they are not in direct contact. "Adhering to the drain channel 2" means that there is a surface-to-surface contact between the upper side 19 of the first steering plate 3 and the drain channel 2, with no gap between them.

[0057] The upper side 19 of the first steering plate 3 facing the drainage channel 2 is close to the drainage channel 2, which reduces the gap between the upper side 19 of the first steering plate 3 facing the drainage channel 2 and the drainage channel 2. This reduces the water flow from the gap between the upper side 19 of the first steering plate 3 facing the drainage channel 2 and the drainage channel 2 into the space where the first steering plate 3 and the flow section form an obtuse angle (two). The water flow towards the rear of the pool cleaning machine in the opposite direction of forward movement is also reduced. This increases the water flow from the gap between the upper side 19 of the first steering plate 3 facing the drainage channel 2 and the drainage channel 2 into the space where the first steering plate 3 and the flow section form an acute angle (one). This makes it easier for the water to flow obliquely to one side of the pool cleaning machine under the guidance of the first steering plate 3 in the drainage channel 2, further improving the turning and movement of the pool cleaning machine, optimizing the turning function, and improving the pool cleaning machine's ability to thoroughly clean the pool.

[0058] The upper side 19 of the first steering plate 3 facing the drainage channel 2 is attached to the drainage channel 2. There is no gap between the upper side 19 of the first steering plate 3 facing the drainage channel 2 and the drainage channel 2. No water flows out from the gap between the upper side 19 of the first steering plate 3 facing the drainage channel 2 and the drainage channel 2 into the space where the first steering plate 3 and the flow section form an obtuse angle. No water flows out directly behind the swimming pool cleaner in the opposite direction of its forward movement. This increases the water flow from the gap between the upper side 19 of the first steering plate 3 facing the drainage channel 2 and the drainage channel 2 into the space where the first steering plate 3 and the flow section form an acute angle. This makes it easier for the water to flow obliquely to one side of the swimming pool cleaner under the guidance of the first steering plate 3 in the drainage channel 2. This further facilitates the turning and movement of the swimming pool cleaner, optimizes the turning function, and improves the swimming pool cleaner's ability to clean the swimming pool comprehensively.

[0059] The first steering plate 3 is rotatably connected to the drainage channel 2. When the pool cleaning machine turns and moves, the first steering plate 3 rotates to the rear side 8 facing the end face 7, which is close to or in contact with the end face 7. When the pool cleaning machine moves straight, the first steering plate 3 rotates to the point where it is perpendicular to the flow section.

[0060] In this way, the pool cleaning machine has both turning and straight-line movement capabilities, improving its versatility.

[0061] The steering device also includes a second steering plate 5, which is parallel to the first steering plate 3 and is connected to the drainage channel 2.

[0062] In this way, when the pool cleaning machine turns and moves, the second steering plate 5 and the first steering plate 3 increase the flow rate of the pool cleaning machine flowing obliquely to one side, thus improving the cleaning effect.

[0063] The steering device also includes a second steering plate 5, which is parallel to the first steering plate 3. The second steering plate 5 is rotatably connected to the drainage channel 2. When the pool cleaning machine turns and moves, the first steering plate 3 rotates to the rear side 8 facing the end face 7, which is close to or in contact with the end face 7. The second steering plate 5 is parallel to the first steering plate 3. When the pool cleaning machine moves straight, the first steering plate 3 rotates to the point where it is perpendicular to the flow section. The second steering plate 5 is parallel to the first steering plate 3.

[0064] Thus, when the pool cleaning machine turns, the second steering plate 5 and the first steering plate 3 increase the flow rate of water flowing obliquely to one side of the pool cleaning machine, improving the cleaning effect during turning. When the pool cleaning machine travels straight, the second steering plate 5 and the first steering plate 3 increase the flow rate of water flowing directly behind the pool cleaning machine in the opposite direction of its forward movement, improving the cleaning effect during straight-line movement.

[0065] Specifically, the steering device also includes a first insertion post 12 and a second insertion post 13. The first insertion post 12 is fixedly connected to the upper side 19 and lower side 9 of the first steering plate 3 facing the drainage channel 2, and the second insertion post 13 is fixedly connected to the upper side 19 and lower side 9 of the second steering plate 5 facing the drainage channel 2. The first insertion post 12 is inserted into the first insertion hole 14 of the drainage channel 2, and the second insertion post 13 is inserted into the second insertion hole 15 of the drainage channel 2. The first insertion post 12 can rotate in the first insertion hole 14, and the second insertion post 13 can rotate in the second insertion hole 15.

[0066] Specifically, the second insertion post 13, which is connected to the upper side 19 of the second steering plate 5 facing the drainage channel 2, is also connected to an anti-detachment part 16. The anti-detachment part 16 is locked in the second insertion hole 15 to prevent the steering device from falling out of the drainage channel 2.

[0067] Specifically, end face 7 is a plane.

[0068] The steering device also includes a linkage block 17, which has a first linkage hole and a second linkage hole. The steering device also includes a first linkage column 18 and a second linkage column 21. The first linkage column 18 is fixedly connected to the upper side 19 of the first steering plate 3 facing the drainage channel 2, and the second linkage column 21 is fixedly connected to the upper side 19 of the second steering plate 5 facing the drainage channel 2. The first linkage column 18 is inserted into the first linkage hole of the linkage block 17, and the second linkage column 21 is inserted into the second linkage hole of the linkage block 17. The first linkage column 18 can rotate in the first linkage hole, and the second linkage column 21 can rotate in the second linkage hole.

[0069] This design enhances the synchronous movement between the first steering plate 3 and the second steering plate 5, preventing a decrease in the flow rate at the outlet 10 due to asynchronous or non-parallel movements between them. This ensures a consistent water flow rate at the outlet 10 and improves the cleaning efficiency of the pool cleaning machine.

[0070] The steering device also includes a rotating column 22, which is fixed on the second steering plate 5. The drainage channel is also provided with a rotating hole 23. The rotating column 22 rotates in the rotating hole 23, and the rotating column 22 drives the second steering plate 5 to rotate. The second steering plate 5 drives the first steering plate 3 to rotate through the linkage block 17.

[0071] Specifically, the rotating hole 23 is shaped like a cone that is wide at both ends and narrow in the middle. This way, the rotating column 22 is stuck at both ends of the rotating hole 23 and is not easy to loosen. When it is necessary to rotate the second steering plate 5, the rotating column 22 is moved. The rotating column 22 comes out from one end and enters the other end through the middle part. When the rotating column 22 is not moved, the rotating column 22 is stuck at both ends and cannot come out. This enhances the stability of the steering and prevents the first steering plate 3 and the second steering plate 5 from shaking and losing the reversing effect.

[0072] A fully automatic swimming pool cleaning machine includes a power unit 11 and an impeller 20, and includes a water outlet structure with optimized steering function as described above.

[0073] Specifically, the impeller 20 is located inside the water inlet channel 1 and is installed at one end of the output shaft of the power unit 11.

[0074] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
