Description

Technical Field

[0001] This application relates to the field of swimming pool cleaning machine technology, and in particular to a fully automatic swimming pool cleaning machine with an irregularly shaped water outlet. Background Technology

[0002] A pool cleaning machine is a device that cleans the bottom of a pool and the surface of the pool to remove dirt and grime. The motor is installed in the casing, and an impeller is located at the end of the motor's output shaft. When the pool cleaning machine is placed in the pool and the motor is turned on, it drives the impeller to rotate. The rotation of the impeller generates thrust. Because there are two motors, the robot can be controlled to move forward or backward underwater. Existing pool cleaning machines use two types of pumps: axial flow pumps and centrifugal pumps. Axial flow pumps offer high power, occupy less space, and increase the space for collecting debris in the inlet chamber below the filter.

[0003] In existing technologies, to improve the grip of pool cleaning machines, the water outlet is angled upwards, with the angle between the outlet and the horizontal plane greater than 0°. However, in existing technologies, the upwardly angled water outlet is used in pool cleaning machines equipped with centrifugal pumps. The upwardly angled water outlet cannot be directly applied to pool cleaning machines with axial flow pumps because the water flow from the impeller is parallel to the horizontal plane. The water flow is subject to resistance from the upwardly angled outlet pipe, resulting in significant kinetic energy loss and a substantial reduction in the forward speed of the pool cleaning machine. Summary of the Invention

[0004] To improve the grip of the fully automatic pool cleaning machine with an axial flow pump in this application while ensuring its forward speed, this application provides a fully automatic pool cleaning machine with an irregularly shaped water outlet, employing the following technical solution:

[0005] An automatic swimming pool cleaning machine with an irregularly shaped water outlet includes a power unit and a water outlet unit. The power unit includes a motor and an impeller, with the impeller fixedly installed at the end of the motor's output shaft. The water outlet unit comprises a cylindrical tube, a transition tube, and an outlet pipe connected in sequence. The impeller is located inside the cylindrical tube, and the axis of the cylindrical tube is collinear with the axis of the output shaft. The transition tube includes a transition surface, and the angle between the transition surface and the cross-section of the cylindrical tube is an acute angle. The outlet pipe includes an upper water outlet surface, a lower water outlet surface, and a side water outlet surface. The lower water outlet surface is connected to the transition surface and is planar. When the automatic swimming pool cleaning machine moves along the bottom of the pool, the lower water outlet surface is parallel to the bottom of the pool, and the side of the upper water outlet surface furthest from the impeller is closer to the impeller than the side of the lower water outlet surface furthest from the impeller.

[0006] The transition surface is S-shaped, and the part of the transition surface that connects to the outlet pipe is an arc surface. Angle 2 between the part of the transition surface that connects to the outlet pipe and the cross-section of the cylindrical pipe is an acute angle. Angle 3 between the part of the transition surface that connects to the cylindrical pipe and the cross-section of the cylindrical pipe is an acute angle. Angle 2 is greater than angle 1, and angle 3 is greater than angle 1. The area of ​​the cross-section of the outlet pipe parallel to the cross-section of the cylindrical pipe is greater than or equal to the cross-sectional area of ​​the cylindrical pipe.

[0007] The lower water outlet surface is symmetrical with respect to the orthographic projection of the output shaft on the lower water outlet surface. The transition surface is symmetrical with respect to the orthographic projection of the output shaft on the transition surface.

[0008] The outlet pipe also includes an upper outlet surface and a side outlet surface, and the distance between the two side outlet surfaces is greater than the diameter of the cylindrical pipe.

[0009] The main body of the motor is installed in the casing of the fully automatic swimming pool cleaning machine. The output shaft of the motor extends out of the casing, and the end of the output shaft is away from the main body of the motor. The water outlet is fixedly installed on one side of the casing.

[0010] The upper housing of the fully automatic swimming pool cleaning machine is equipped with a fixing hole. The inner surface of the fixing hole has the same shape as the outer surface of the outlet pipe, and the inner surface of the fixing hole fits into the outer surface of the outlet pipe.

[0011] The upper shell includes a main shell and an end shell, which are detachably fixedly connected. A fixing hole is formed between one side of the main shell and one side of the end shell.

[0012] A positioning block is provided on the outer surface of the outlet pipe, and the side of the end shell closest to the chassis abuts against the positioning block.

[0013] The ring cover of the pool cleaning machine is fixedly installed on the side of the upper housing away from the machine casing, and the ring cover is fastened to the lower housing of the pool cleaning machine.

[0014] The outer surface of the outlet pipe on the side away from the impeller is located on the arc surface of the outer surface of the upper housing of the fully automatic pool cleaning machine.

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

[0016] 1. By means of the design in this application, the grip of the fully automatic pool cleaning machine with axial flow pump in this application is improved while the kinetic energy loss is minimized, thus ensuring the forward speed of the fully automatic pool cleaning machine; 2. When the water flows through the part where the transition surface connects to the cylindrical pipe, and when the water flows through the part where the transition surface connects to the cylindrical pipe, the forward speed of the fully automatic pool cleaning machine is prevented from decreasing too much, thus ensuring the forward speed of the fully automatic pool cleaning machine.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-13 This application will be described in further detail.

[0032] As shown in the attached diagram of the instruction manual. Figure 1-8 As shown, a fully automatic swimming pool cleaning machine with an irregularly shaped water outlet includes a power unit 2 and a water outlet 3. The power unit 2 includes a motor 19 and an impeller 6. The impeller 6 is fixedly installed at the end of the output shaft 7 of the motor 19. The water outlet 3 includes a cylindrical tube 13, a transition tube 14 and an outlet pipe connected in sequence. The impeller 6 is located inside the cylindrical tube 13, and the axis of the cylindrical tube 13 is collinear with the axis of the output shaft 7. The transition tube 14 includes a transition surface 11, and the angle α1 between the transition surface 11 and the cross-section of the cylindrical tube 13 is an acute angle. The outlet pipe includes an upper water outlet surface 15, a lower water outlet surface 16 and a side water outlet surface 18. The lower water outlet surface 16 is connected to the transition surface 11 and is a plane. When the fully automatic swimming pool cleaning machine moves on the bottom of the pool, the lower water outlet surface 16 is parallel to the bottom of the pool, and the side of the upper water outlet surface 15 away from the impeller 6 is closer to the impeller 6 than the side of the lower water outlet surface 16 away from the impeller 6.

[0033] In existing technologies, to improve the grip of pool cleaning machines, the entire outlet section is angled upwards, with the angle between the outlet section and the horizontal plane of the pool bottom greater than 0°. However, in existing technologies, the angled upward-facing outlet section is used in pool cleaning machines equipped with centrifugal pumps. An angled upward-facing outlet section cannot be directly applied to pool cleaning machines equipped with axial flow pumps because the water flow direction from the impeller in an axial flow pump is parallel to the pool bottom. If water flows into a completely angled upward-facing outlet section, the resistance from the angled section will result in significant kinetic energy loss, greatly reducing the forward speed of the pool cleaning machine and consequently, significantly decreasing cleaning efficiency.

[0034] To improve the grip of the fully automatic pool cleaning machine with an axial flow pump in this application while minimizing kinetic energy loss, an irregularly shaped water outlet section is utilized. The water outlet section 3 includes a cylindrical pipe 13, a transition pipe 14, and an outlet pipe connected in sequence. The angle α1 between the transition surface 11 and the cross-section of the cylindrical pipe 13 is an acute angle. The water flowing out of the transition pipe 14 is divided into two parts: the first part flows along the transition surface 11, and the second part flows without flowing along the transition surface 11. When the fully automatic pool cleaning machine is running at the bottom of the pool, the water flowing out from the impeller passes through the transition pipe 14. The first part of the water flow is tilted upward by the action of the transition surface 11. At the same time, the water flow exerts a downward force on the transition surface 11, which improves the grip of the fully automatic pool cleaning machine. The side of the upper water outlet 15 that is away from the impeller 6 is closer to the impeller 6 than the side of the lower water outlet 16 that is away from the impeller 6. This reduces the obstruction of the upper water outlet 15 on the first part of the water flow after the outlet pipe, ensuring that a part of the water flow continues to flow upward from outside the upper water outlet 15 after the outlet pipe. This helps to maintain a downward force exerted on the transition surface 11 by the water flow, thus ensuring the grip of the fully automatic pool cleaning machine.

[0035] The first part of the water flows along the transition surface 11 and then flows out along the lower outlet surface 16. When the fully automatic pool cleaning machine moves on the bottom of the pool, the lower outlet surface 16 is parallel to the bottom of the pool. The first part of the water flows through the transition surface 11 and then flows out along the lower outlet surface 16. It is no longer blocked by the transition surface 11. The resistance of the first part of the water flow is reduced, and the loss of kinetic energy is reduced.

[0036] The second part of the water flow does not flow along the transition surface 11. After the second part of the water flow out of the transition pipe 14 except for the transition surface 11, the second part of the water flow flows out at a higher level than the lower water surface 16 and is not blocked by the transition surface 11. The second part of the water flow is not resisted by the transition surface 11 and there is no loss of kinetic energy.

[0037] Therefore, through the design of this application, the grip of the fully automatic pool cleaning machine with axial flow pump in this application is improved while the loss of kinetic energy is minimized, ensuring the forward speed of the fully automatic pool cleaning machine and improving the overall cleaning efficiency.

[0038] Specifically, the main body of motor 19 is installed in the housing 5 of the fully automatic swimming pool cleaning machine, and the output shaft 7 of motor 19 extends out of housing 5, with the end of the output shaft 7 of motor 19 away from the main body of motor 19.

[0039] As shown in the attached diagram of the instruction manual. Figure 6As shown, the transition surface 11 is S-shaped, and the part of the transition surface 11 that connects to the outlet pipe is an arc surface. The angle α2 between the part of the transition surface 11 that connects to the outlet pipe and the cross-section of the cylindrical pipe 13 is an acute angle. The part of the transition surface 11 that connects to the cylindrical pipe 13 is an arc surface, and the angle α3 between the part of the transition surface 11 that connects to the cylindrical pipe 13 and the cross-section of the cylindrical pipe 13 is an acute angle. Angle α2 is greater than angle α1, and angle α3 is greater than angle α1. The area of ​​the cross-section of the outlet pipe parallel to the cross-section of the cylindrical pipe 13 is greater than or equal to the cross-sectional area of ​​the cylindrical pipe 13.

[0040] In this way, since the direction of water flow from the fully automatic pool cleaning machine is opposite to the direction of its forward movement, when the water flow just passes the part where the transition surface 11 connects to the cylindrical tube 13, the direction of the water flow is not within the cross-section of the cylindrical tube 13, but has a certain angle with the cross-section of the cylindrical tube 13. This angle is acute. Since the angle α3 between the part where the transition surface 11 connects to the cylindrical tube 13 and the cross-section of the cylindrical tube 13 is acute, the angle between the direction of the water flow and the cross-section of the cylindrical tube 13 matches perfectly with α3. When the water flows through the part where the transition surface 11 connects to the cylindrical tube 13, the kinetic energy loss of the water flow is minimized, avoiding an excessive decrease in the forward speed of the fully automatic pool cleaning machine and ensuring the forward speed of the fully automatic pool cleaning machine. Furthermore, when the water flow just passes through the section where the transition surface 11 connects to the cylindrical tube 13, the cross-sectional area through which the fluid passes changes direction, increasing the relative motion of fluid particles and thus increasing viscous internal friction loss. However, since the section where the transition surface 11 connects to the cylindrical tube 13 is an arc surface, the cross-sectional area through which the fluid passes changes direction slowly, reducing viscous internal friction loss and minimizing kinetic energy loss of the water flow. This ensures the forward speed of the fully automatic pool cleaning machine.

[0041] After the water flows through the transition surface 11, the flow direction at the point where the transition surface 11 connects to the outlet pipe forms an acute angle with the cross-section of the cylindrical pipe 13. The angle α2 between the transition surface 11 and the outlet pipe and the cross-section of the cylindrical pipe is also acute. Thus, the angle between the water flow direction and the cross-section of the cylindrical pipe 13 perfectly aligns with α2, minimizing the kinetic energy loss of the water flow at the point where the transition surface 11 connects to the cylindrical pipe 13. This prevents excessive reduction in the forward speed of the automatic pool cleaning machine, ensuring its continued forward speed. Furthermore, immediately after the water flows through the point where the transition surface 11 connects to the outlet pipe, the cross-sectional area changes direction, increasing the relative motion of fluid particles and thus increasing viscous internal friction loss. However, because the transition surface 11 is curved, the cross-sectional area changes direction slowly, reducing viscous internal friction loss and minimizing kinetic energy loss. This further ensures the continued forward speed of the automatic pool cleaning machine.

[0042] The area of ​​the cross section of the outlet pipe parallel to the cross section of the cylindrical pipe 13 is greater than or equal to the cross-sectional area of ​​the cylindrical pipe 13. Thus, the cross-sectional area of ​​the water flow passing through the outlet pipe is greater than or equal to the cross-sectional area of ​​the water flow passing through the cylindrical pipe 13. This ensures that the cross-sectional area of ​​the second part of the water flow is large enough, and more of the second part of the water flow is not subject to the resistance of the transition surface 11, so there is no loss of kinetic energy.

[0043] As shown in the attached diagram of the instruction manual. Figure 3-8 As shown, the lower water outlet surface 16 is symmetrical with respect to the orthographic projection of the output shaft 7 on the lower water outlet surface. The transition surface 11 is symmetrical with respect to the orthographic projection of the output shaft 7 on the transition surface 11.

[0044] This makes the force of the water flow propelling the fully automatic pool cleaning machine more even on both sides, resulting in a smoother ride.

[0045] As shown in the attached diagram of the instruction manual. Figure 4 As shown, the outlet pipe also includes an upper water outlet surface 15 and a side water outlet surface 18, and the distance L between the two side water outlet surfaces 18 is greater than the diameter D of the cylindrical pipe 13.

[0046] This increases the width of the water flow cross-section from the outlet pipe, expanding the range of the force exerted by the water flow perpendicular to the propulsion of the fully automatic pool cleaning machine. This makes the force of the water flow in propelling the fully automatic pool cleaning machine more uniform, resulting in a smoother operation of the machine.

[0047] As shown in the attached diagram of the instruction manual. Figure 7 , Figure 8 and 13 As shown, the main body of motor 19 is installed in the housing 5 of the fully automatic swimming pool cleaning machine. The output shaft of motor 19 extends out of housing 5, and the end of the output shaft of motor 19 is away from the main body of motor 19. The water outlet is fixedly installed on one side of housing 5.

[0048] This enhances the stability of the positional relationship between the water outlet and the output shaft 7.

[0049] Specifically, the water outlet is fixedly installed on one side of the casing 5. The casing 5 and the water outlet are fixedly connected by plug-in connection. Mounting posts are provided on both sides of the casing 5. Mounting holes are provided on the side of the water outlet near the casing 5. The mounting posts are inserted into the mounting holes.

[0050] As shown in the attached diagram of the instruction manual. Figure 1 , Figure 7 and Figure 8 As shown, the upper housing of the fully automatic swimming pool cleaning machine is provided with a fixing hole. The inner surface of the fixing hole has the same shape as the outer surface of the outlet pipe, and the inner surface of the fixing hole fits into the outer surface of the outlet pipe.

[0051] This secures the outlet pipe within the upper housing, preventing it from wobbling during operation.

[0052] As shown in the attached diagram of the instruction manual. Figure 1 , Figure 7 , Figure 8-11 As shown, the upper shell includes a main shell 1 and an end shell 4, which are detachably fixedly connected. A fixing hole is formed between one side of the main shell and one side of the end shell 4.

[0053] During the assembly of the fully automatic swimming pool cleaning machine, after the outlet section and the casing 5 are assembled into a whole, the outlet pipe is attached to one side of the main shell 1, and the inner surface of one side of the end shell 4 is attached to the outlet pipe. Then, one side of the main shell 1 and one side of the end shell 4 are fixedly connected. This makes it easier to install the whole assembly of the water outlet section and the casing 5 into the upper shell, and also reduces the size of the entire upper shell in the length direction of the fully automatic swimming pool cleaning machine.

[0054] As shown in the attached diagram of the instruction manual. Figure 7 and Figure 8 As shown, a positioning block 8 is provided on the outer surface of the outlet pipe, and the side of the end shell 4 near the chassis 5 abuts against the positioning block 8.

[0055] This prevents end shell 4 from swaying or shifting relative to the water outlet pipe, thus improving the stability and sealing of the entire upper shell.

[0056] As shown in the attached diagram of the instruction manual. Figure 1 and Figure 12 As shown, the ring cover 10 of the pool cleaning machine is fixedly installed on the side of the upper housing away from the machine casing 5, and the ring cover 10 is fastened to the lower housing 9 of the pool cleaning machine.

[0057] Specifically, wedge-shaped blocks are provided on both sides of the ring cover 10, and protruding blocks corresponding to the wedge-shaped protrusions are provided on both sides of the lower housing 9. The ring cover and the lower housing 9 are fastened together by the wedge-shaped blocks and the protruding blocks.

[0058] As shown in the attached diagram of the instruction manual. Figure 12 As shown, the outer surface of the outlet pipe on the side away from the impeller 6 is located on the arc surface of the outer surface of the upper housing of the fully automatic pool cleaning machine.

[0059] This reduces the resistance of the water outlet pipe to the water flow, preventing excessive energy consumption of the fully automatic pool cleaning machine due to excessive resistance, thus saving electricity and extending the service life of the fully automatic pool cleaning machine.

[0060] The filter screen of the fully automatic pool cleaner is installed inside the lower housing 9 at the top, and a water inlet is provided at the bottom of the lower housing 9. The baffle 17 of the pool cleaner is installed on the outlet pipe. In this way, when water is discharged from one of the outlet pipes of the fully automatic pool cleaner, the baffle 17 of the other outlet pipe covers the outlet of the other outlet pipe to prevent water from entering from the other outlet pipe.

[0061] 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.
