Automatic door lock engages when the washing cycle starts, securing the door to prevent pets and children from accessing the drum. During high-speed spin, the inner drum may vibrate. The door lock features a suspended fixed structure and locking design to stabilize the hatch, prevent component loosening due to door movement, and reduce vibration-related stress on the machine frame. The closing process includes obstacle detection and a rebound safety feature that prevents finger pinching when the door encounters obstructions. The door lock and hatch seal tightly to prevent washing water from entering the washer, reducing the risk of electrical short circuits and water damage to internal components. Use scenarios: - Homes with young children or pets: ensures safe operation by keeping the drum securely closed during washing. - Heavily loaded or high-speed wash cycles: stabilization helps maintain reliability by minimizing vibration and protecting the machine structure. - Environments with moisture or splash exposure: robust sealing prevents water ingress to protect electronics and motor components.
