Technical Field

[0001] This utility model belongs to the technical field of swimming pool cleaning equipment, specifically relating to a battery pack heat dissipation structure for a swimming pool cleaning robot and the swimming pool cleaning robot itself. Background Technology

[0002] Pool cleaning robots are used to clean swimming pools. Their main working principle is to use an impeller pump to draw water from the pool into the machine body, and then discharge it outward after passing through a filter module.

[0003] Because pool cleaning robots operate in water, the sealing requirements for electrical components are extremely stringent. Currently, the batteries in existing pool cleaning robots are typically fixed directly to the bottom of the robot's casing, with the control panel and sealing structure located on the top. During operation, the batteries generate significant heat when discharging, especially in hot summer water conditions. Poor heat dissipation leads to reduced battery efficiency and lifespan.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0014] In one embodiment, the battery pack is positioned near the bottom of the housing.

[0015] In one embodiment, the pool cleaning robot includes a control board for controlling the impeller pump, the control board being disposed within the sealed housing.

[0016] In one embodiment, the control board is positioned above the battery pack mounting cavity, and there is a gap between the control board and the battery pack.

[0017] In one embodiment, the impeller pump includes an impeller and a motor that is driven to drive the impeller. The motor is suspended inside the sealed housing, and the motor has heat dissipation gaps on its periphery and bottom.

[0032] Example 1

[0033] This embodiment provides a pool cleaning robot for cleaning swimming pools. Figure 1 This is a three-dimensional structural diagram of the pool cleaning robot provided in an embodiment of the present invention. Figure 2 for Figure 1 The diagram shows a longitudinal cross-sectional view of the pool cleaning robot along the front-to-back direction. Figure 3 for Figure 1 The diagram shows a cross-sectional view of the pool cleaning robot along the left-right direction. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 The pool cleaning robot 100 includes a housing 10, an impeller pump 20, a battery pack 30, and a sealed housing 40.

[0034] The outer casing 10 defines a filter chamber 13. An inlet 11 is located at the bottom of the outer casing 10, and a drain 12 is located on the upper side of the outer casing 10. The inlet 11 and drain 12 are connected to the filter chamber 13. An impeller pump 20 is disposed within the outer casing 10 and drives water to flow into the filter chamber 13 through the inlet 11 and out through the drain 12. In a specific embodiment, a filter assembly 70 is also disposed within the filter chamber 13 to filter the water. The filter assembly 70 intercepts particulate impurities in the water to purify it. To facilitate cleaning, the filter assembly 70 is detachably disposed within the filter chamber 13.

[0035] For clarity, please refer to [link / reference]. Figure 2 and 3 The pool cleaning robot is in a horizontal support state. The forward direction of the pool cleaning robot is defined as "forward" and the opposite direction is "backward". The top of the pool cleaning robot is "up" and the opposite direction is "down". With the forward direction as a reference, the left side of the pool cleaning robot is "left" and the right side is "right".

[0036] The pool cleaning robot 100 also includes a walking mechanism 90, which is disposed on the left and right sides of the outer casing 10 and is used to drive the pool cleaning robot 100 to move. Specifically, the walking mechanism 90 includes walking wheels, tracks wound around the walking wheels, and drive motors that drive the walking wheels. The drive motors drive the walking wheels to rotate, thereby driving the tracks to rotate, thus driving the pool cleaning robot to move.

[0037] The pool cleaning robot 100 also includes a cleaning roller brush 80, which is located at the bottom and front of the housing 10. The cleaning roller brush 80 is connected to the drive wheels and rotates synchronously with them. When the pool cleaning robot 100 is in cleaning mode, the drive motor drives the drive wheels and the cleaning roller brush 80 to rotate clockwise (to...). Figure 2(The orientation shown in the drawing is for reference only). The cleaning roller brush 80 contacts the pool wall to clean it. The clockwise rotation of the cleaning roller brush 80 also helps to provide forward driving force for the pool cleaning robot.

[0038] The impeller pump 20 is disposed within the housing 10 along the vertical direction. The impeller pump 20 includes an impeller 21 and a motor 24 driven by the impeller 21. The motor 24 drives the impeller 21 to rotate, thereby driving the pool water to form a cleaning circulation. Specifically, the impeller 21 is located directly above the motor 24 and is fixed on the output shaft of the motor 24. When the motor 24 rotates, the impeller 24 rotates around its axis, and the pool water flows in from the inlet 11, passes through the filter assembly 70 and the impeller 21 in sequence, and is discharged outward from the outlet 12.

[0039] The battery pack 30 provides power to the impeller pump 20. Specifically, a sealing shell 40 is disposed within the outer shell 10, and the battery pack 30 is disposed within the sealing shell 40. More specifically, a battery pack mounting cavity 42 is formed inside the sealing shell 40 to accommodate the battery pack 30, and the battery pack 30 is disposed within the battery pack mounting cavity 42. The bottom of the sealing shell 40 is disposed within the outer shell 10 with a gap, and a bottom isolation cavity 50 is formed between the sealing shell 40 and the bottom wall of the outer shell 10. At least one side of the battery pack mounting cavity 42 has a side isolation cavity 60. When the pool cleaning robot is in water, the bottom and at least one side of the battery pack mounting cavity 42 are immersed in water. That is, the battery pack mounting cavity 42 and the bottom wall of the outer shell 10 are spaced apart, forming a bottom isolation cavity 50 between them, and at least one side wall of the battery pack mounting cavity 42 has a side isolation cavity 60, so that at least one side of the battery pack mounting cavity 42 also has a cavity structure. When the pool cleaning robot is working submerged in water, the bottom and at least one side of the battery pack mounting cavity 42 are in a water environment, which can utilize the pool water to improve the heat dissipation of the battery pack 30 and improve the working efficiency of the battery pack.

[0040] To further ensure the heat dissipation effect of the battery pack, the battery pack mounting cavity 42 has side isolation cavities 60 on the outer side of its circumferential sidewalls. The side isolation cavities 60 and the bottom isolation cavity 50 are interconnected and surround the bottom and sides of the battery pack mounting cavity 42. When the pool cleaning robot is submerged in water, the bottom and circumferential sides of the battery pack mounting cavity 42 are in a water environment, with a large contact area with water, which helps to improve heat dissipation efficiency.

[0041] In a specific embodiment, the battery pack has a thickness dimension, a width dimension, and a length dimension, wherein the thickness dimension is smaller than its width and length dimensions. The length direction of the battery pack 30 is parallel to the left-right direction of the pool cleaning robot 100, the thickness direction of the battery pack 30 is parallel to the up-down direction of the pool cleaning robot 100, and the width direction of the battery pack 30 is parallel to the front-back direction of the pool cleaning robot 100. The battery pack occupies a small height space, which helps to improve the compactness of the pool cleaning robot. For example, the battery pack 30 is rectangular.

[0042] Furthermore, the battery pack 30 is positioned near the bottom wall of the outer casing 10, placing it in a relatively low position within the casing 10 of the pool cleaning robot 100. In water entry scenarios, the lower position allows water to enter first, and in water exit scenarios, the lower position allows water to exit last. This ensures that the battery pack mounting cavity can be quickly submerged in the water environment, guaranteeing effective heat dissipation. Moreover, since battery packs are typically heavy, this lower positioning helps lower the center of gravity of the pool cleaning robot.

[0043] Please pay close attention. Figure 2 The pool cleaning robot 100 includes a control board (not shown) for controlling the impeller pump 20. The sealed housing 40 also includes a control mounting cavity 43, within which the control board is disposed. The control board 20 is electrically connected to the impeller pump 20 and is used to control the operation of the impeller pump 20. The control board 20 is also electrically connected to the roller brush motor and the walking mechanism 90 and is used to control the operation of the roller brush motor and the walking mechanism 90.

[0044] To reduce the thermal impact of the control board's heat on the battery pack 30, in this specific embodiment, the control mounting cavity 43 is positioned higher than the battery pack mounting cavity 42, and the control board is positioned higher than the battery pack mounting cavity. This creates a space between the control board and the battery pack to form a heat dissipation gap, minimizing the mutual thermal interference between the two. Specifically, a protruding post is provided above the battery pack mounting cavity 42, extending upwards to the middle of the control mounting cavity 43, and the control board is fixedly supported on the top of the protruding post.

[0045] The sealing housing 40 also includes a motor mounting cavity 46 for sealing the motor 24 of the impeller pump 20. The motor 24 is suspended within the motor mounting cavity 46, and has cavities on its periphery and bottom. The upper end of the motor 24 is fixed to the upper wall of the motor mounting cavity 46, and the motor 24 has heat dissipation gaps on its periphery and bottom. This design helps to suppress the impact of motor heat generation on the battery pack temperature and also improves the motor's heat dissipation.

[0046] Furthermore, the battery pack 30 is located directly below the motor 24, with a gap between them. This gap reduces the mutual heat exchange between the battery pack 30 and the motor 24. Furthermore, the battery pack mounting cavity 42 and the motor mounting cavity 46 are separated by a partition, sealing them together and further suppressing the mutual heat exchange between the battery pack and the motor. Of course, a partition may not be used between the battery pack and the motor; this is not a limitation.

[0047] Similarly, a partition can be installed between the battery pack and the control board for isolation, or no partition can be installed; there is no restriction here.

[0048] The outer shell 10 includes an upper shell and a lower shell, which are mated and fixed together. Figure 4 A three-dimensional structural diagram of the lower shell of the outer casing 10 is shown. A support structure 14 protrudes upward from the inner side of the lower shell of the outer casing 10 to support the sealing shell 40. There are multiple support structures 14, which are distributed directly below the bottom edge of the sealing shell 40. Each support structure 14 abuts against the bottom and side of the sealing shell 14, thereby achieving support and positioning of the sealing shell 40.

[0049] Figure 5 An enlarged schematic diagram of a support structure 14 is shown. The support structure 14 includes a base 141 and support and limiting ribs 142 disposed on the base 141. The base 141 extends upward from the inner wall of the lower shell, and the support and limiting ribs 142 extend outward from the surface of the base 141. There are multiple support and limiting ribs 142, and the outer edge shape of each support and limiting rib 142 matches the lower outer contour of the sealing shell 40. The support and limiting ribs 142 simultaneously cooperate with the bottom and side walls of the sealing shell 40, so that each support and limiting rib 142 can provide support for the sealing shell 40 and limit it in a certain circumferential direction. Through multiple support structures 14, the bottom support and circumferential limitation of the sealing shell 40 can be achieved. Specifically, the support structure 14 also includes reinforcing ribs 143, which are connected to or integrally formed with the base 141. The support and limiting ribs 142 and the reinforcing ribs 143 are located on opposite sides of the base 141 to increase the strength of the support structure 14. Each support structure 14 has the same structure and is arranged to match the outer contour of the corresponding corner of the sealing shell. Other support structures will not be described in detail.

[0050] In a specific embodiment, the bottom surface of the sealing shell 40 is rectangular, and there are four support structures 14, which are respectively supported at the four corners of the bottom surface of the sealing shell 40. The four support structures 14 support the sealing shell 40 above the lower shell at the four corners, and restrict the horizontal displacement of the sealing shell 40 at the four corners, thus achieving the initial positioning of the sealing shell 40.

[0051] In a specific embodiment, the pool cleaning robot 100 further includes a filter frame 17 for defining the filter chamber 13. The filter frame 17 is integrally formed or fixedly connected to the outer shell 10, and the filter assembly 70 is disposed within the filter frame 17. The upper end of the sealing shell 40 is fixedly connected to the filter frame 17. Thus, the lower end of the sealing shell is supported and circumferentially limited by the support structure, while the upper end is fixed to the filter frame, thereby fixing the sealing shell within the outer shell.

[0052] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
