Pool Robot Gravity-Driven Drainage for Rapid Water Evacuation

The patent implements preliminary drainage action by providing drainage holes in the housing that are positioned to drain water automatically when the robot is tilted during extraction. The drainage holes are arranged at specific locations (front surface, side surface, rear surface) that enable water to flow out before the user fully removes the robot from the pool, reducing the weight the user must handle.

The patent uses the housing structure itself as an intermediary drainage system. The housing includes multiple drainage holes that serve as intermediaries between the internal water-filled cavity and the external environment. These holes allow water to escape through the housing walls when tilted, mediating the transition from water-filled to drained state during extraction.

The patent segments the drainage function by providing multiple drainage holes distributed across different surfaces of the housing (front surface, side surface, rear surface). This segmentation of the drainage pathway into multiple parallel outlets significantly increases the total drainage cross-sectional area, enabling water to drain simultaneously through multiple locations rather than a single point, thereby accelerating the drainage process.

The patent utilizes the spatial dimension by positioning drainage holes on multiple surfaces (front, side, rear) of the housing rather than concentrating them on a single surface. This multi-dimensional arrangement of drainage openings allows water to escape from various directions simultaneously when the robot is tilted, maximizing the use of gravitational force and dramatically improving drainage efficiency.
