[0034] The existing window cleaning machine's drive unit suffers from low heat dissipation efficiency.

[0035] 1. When a window cleaning machine moves on heavily soiled glass, the high coefficient of friction on the glass surface necessitates an increased operating current from the drive unit to overcome this friction and propel the machine. This increased current, coupled with the existing structure's inability to meet the heat dissipation requirements of the drive unit, can lead to overheating, resulting in shutdowns, malfunctions, or burnout.

[0036] 2. Window cleaning machines operate on glass using negative pressure, resulting in limited airflow through the drive unit. Prolonged operation or exposure to direct sunlight can cause the drive unit to overheat. The existing structure cannot adequately meet the heat dissipation requirements of the drive unit, thus increasing the risk of overload.

[0037] The window cleaning machine proposed in this application can achieve efficient heat dissipation of the drive unit.

[0038] Example

[0039] See Figures 1-3 In this embodiment, a window cleaning machine 10 is proposed, including a liquid storage device 100 for storing cleaning fluid and a drive device 200 for driving the window cleaning machine 10 to move. It should be noted that, for easier observation of the internal structure of the window cleaning machine 10, Figure 1-3 The top cover of the window cleaning machine 10 is not shown in either of the images.

[0040] The cleaning solution includes water or a mixture of water and cleaning agent. The drive unit 200 includes a motor.

[0041] At least a portion of the liquid storage device 100 is disposed on the drive device 200, allowing the cleaning fluid to flow through the drive device 200. When the window cleaning machine 10 is running, the cleaning fluid stored in the liquid storage device 100 flows through the drive device 200 to cool the drive device 200, thereby preventing overheating and ensuring normal and stable operation. Liquid cooling enables efficient heat dissipation from the drive device 200.

[0042] The volume of the liquid storage device 100 can be set as needed. In some embodiments, a larger volume liquid storage device 100 can be installed, thereby storing more cleaning fluid and reducing the frequency of cleaning fluid addition.

[0043] The drive unit 200 is used to drive the window cleaning machine 10 to move so that the cleaning fluid sloshes and flows through the liquid storage device 100 on the drive unit 200.

[0044] Specifically, when the window cleaning machine 10 is running, in order to dissipate heat from the drive unit 200, the drive unit 200 drives the window cleaning machine 10 to move on the glass. During this process, the movement of the window cleaning machine 10 causes the flowing cleaning fluid to slosh, thereby causing the cleaning fluid to slosh and flow through the liquid storage device 100 on the drive unit 200.

[0045] Agitation disrupts the laminar flow of the cleaning fluid, creating turbulence. This increases the contact efficiency between the cleaning fluid and the inner wall of the storage device 100, improving heat transfer rate and enhancing heat dissipation efficiency and effectiveness. Furthermore, agitation prevents the cleaning fluid from stagnating or adhering in localized areas, ensuring that the heat absorbed by the cleaning fluid is carried away with its flow, thus avoiding localized overheating.

[0046] Alternatively, the cleaning fluid in the storage device 100 can be driven to flow by a water pump.

[0047] The window cleaning machine 10 can move in the following ways: linear movement, rotational movement, and swinging movement.

[0048] Reference Figure 4 When the window cleaning machine 10 moves in the direction indicated by arrow A and moves from position W1 to position W2, the window cleaning machine 10 is in a linear movement state.

[0049] Reference Figure 5 When the window cleaning machine 10 moves in the direction shown by arrow B and moves from position W3 to position W4, the window cleaning machine 10 is in a rotating movement state.

[0050] Reference Figure 6 When the window cleaning machine 10 moves sequentially in the directions indicated by arrows C and D, and moves from position W5 through position W6 to position W7, the window cleaning machine 10 is in a swinging movement state.

[0051] When the window cleaning machine 10 moves in an oscillating motion, the cleaning fluid agitates more, resulting in better cooling of the drive unit 200.

[0052] In this embodiment, the window cleaning machine 10 includes a spraying device 300. The spraying device 300 is used to spray cleaning liquid. The specific structure of the spraying device 300 can refer to existing designs and will not be described in detail here.

[0053] The spray device 300 is connected to the liquid storage device 100 so that the air pressure inside the spray device 300 and the liquid storage device 100 is maintained within a preset air pressure range.

[0054] The spray device 300 is connected to the liquid storage device 100, forming a communicating vessel. This allows the entire assembly of the spray device 300 and the liquid storage device 100 to store more cleaning fluid and maintain the internal pressure within a preset range. When the spray device 300 is operating, the cleaning fluid stored in the window cleaning machine 10 continuously decreases. Because the internal pressure of the spray device 300 and the liquid storage device 100 remains within the preset range, negative pressure is avoided, preventing the spray device 300 from spraying cleaning fluid. This ensures that cleaning fluid can always be sprayed through the spray device 300.

[0055] When the window cleaning machine 10 is running, the spray device 300 is located below the liquid storage device 100, which is used to provide spray power for the spray device 300 under its own gravity.

[0056] Reference Figures 3-6 In this embodiment, there are two spray devices 300, positioned on either side of the window cleaning machine 10 in the width direction. When the window cleaning machine 10 runs in any direction, at least one of the spray devices 300 sprays cleaning liquid in the direction of operation. Figure 3 In this configuration, the width of the window cleaning machine 10 aligns with the horizontal direction. Alternatively, a single spray device 300 can be included, depending on specific requirements.

[0057] There are two drive units 200. When the window cleaning machine 10 is running, one drive unit 200 is located above the corresponding spray device 300, and the other drive unit 200 is located below the corresponding spray device 300.

[0058] When the window cleaning machine 10 moves, the cleaning fluid sloshes, causing it to flow between the spray device 300 and the drive device 200 adjacent to the spray device 300, thereby improving heat dissipation efficiency.

[0059] The liquid storage device 100 forms a circulation loop inside the window cleaning machine 10, allowing the cleaning fluid to circulate through the drive unit 200. This allows the cleaning fluid in the storage device 100 to absorb the heat generated by the drive unit 200, thereby reducing the temperature of the drive unit 200. Figure 3 As shown, in one embodiment, the cleaning fluid in the storage device 100 flows in the direction indicated by the arrow in the figure.

[0060] like Figure 3As shown, in this embodiment, the window cleaning machine 10 also includes a circuit board 400, and at least a portion of the liquid storage device 100 is disposed on the circuit board 400 so that the cleaning liquid flows through the circuit board 400. The pipe portion of the liquid storage device 100 can be attached to the circuit board 400, so that when the cleaning liquid flows through the circuit board 400, it can carry away the heat generated by the circuit board 400, thereby cooling the circuit board 400.

[0061] like Figure 2 and Figure 3 As shown, the liquid storage device 100 includes a first part 110 and a second part 120. The first part 110 is disposed on the drive device 200, and the second part 120 is disposed inside the window cleaning machine 10.

[0062] The first part 110 includes a hollow housing. The first part 110 corresponds one-to-one with the drive device 200. The shape of the first part 110 corresponds to the corresponding drive device 200, wherein the first part 110 can be attached to the outer surface of the drive device 200, thereby increasing the contact area and improving heat dissipation efficiency. In some embodiments, a thermally conductive pad or thermally conductive silicone or other thermally conductive medium can be disposed between the first part 110 and the drive device 200, thereby filling the gap between the first part 110 and the drive device 200, thereby improving thermal conductivity.

[0063] The second part 120 includes pipes and water tanks, etc. In some embodiments, the second part 120 may be a flexible hose or a rigid pipe; in other embodiments, the second part 120 may also be a combination of flexible hoses and rigid pipes, for example, flexible hoses in some parts and rigid pipes in some parts.

[0064] The liquid storage device 100 also includes a liquid storage tank 130. The volume and capacity of the liquid storage tank 130 are larger than those of the first part 110. When adding cleaning fluid, the cleaning fluid is poured into the liquid storage tank 130 through the inlet on the liquid storage tank 130. The first part 110, the second part 120, and the liquid storage tank 130 are connected. By setting up the liquid storage tank 130, the storage capacity of the cleaning fluid is increased, the frequency of adding cleaning fluid is reduced, and more heat generated from the drive device 200 and the circuit board 400 can be absorbed, thus improving the heat dissipation effect.

[0065] like Figure 7 and Figure 8 As shown, in this embodiment, the first part 110 includes a water inlet 111 and a water outlet 112. The water inlet 111 and the water outlet 112 are located at the two ends of the first part 110 that are furthest apart, so as to increase the flow path of the cleaning fluid in the window cleaning machine 10, thereby improving the heat dissipation area and efficiency. Figure 7 and Figure 8 The middle arrow indicates the flow direction of the cleaning fluid inside the first part 110.

[0066] In this embodiment, the window cleaning machine 10 also includes a water pump, which is used to drive the cleaning fluid to flow. The water pump is connected to the liquid storage device 100, and the installation position of the water pump can be set according to the internal space of the window cleaning machine 10.
