Systems and methods for filtering microplastics, lint, and other foreign particulates from water or air streams within laundry appliances, often including self-cleaning or blockage detection mechanisms.
Mechanisms for storing, dispensing, and monitoring the delivery of liquid or solid laundry additives (detergents, softeners) into the wash fluid, including diagnostics for ensuring correct operation.
Systems for storing, heating, pumping, and precisely dispensing water or cleaning solutions within domestic appliances or cleaning tools. This includes cartridge-based systems, dissolvable cleaning agents, and controlled fluid delivery for optimal cleaning performance.
Systems and mechanisms that allow autonomous cleaning robots or devices to return to a base station for automated tasks such as mop washing, dustbin emptying, fluid replenishment, or cleaning of tool heads without human intervention.
Appliances or modules designed for specific garment care tasks beyond conventional washing and drying, such as steaming, ironing, or autonomous dry-cleaning processes.
Technologies for monitoring the operational status of laundry appliances, identifying abnormal conditions (e.g., pump blockages, motor issues, external noise), and initiating responsive actions or alerts.
Utilizes sensors and intelligent algorithms to detect laundry load characteristics, operational conditions (e.g., imbalance, resonance, dryness), and dynamically adjust washing or drying cycles for optimal performance and efficiency.
Processes that use strong oxidants, electrochemical methods, sonic waves, or other energy-intensive techniques to break down organic pollutants, disinfect water, or facilitate contaminant separation.
Design features and accessories that improve the installation, storage, usability, and overall user experience of household cleaning appliances and manual tools. This includes mounting brackets, ergonomic handles, and integrated storage solutions.
Innovations in vacuum cleaner components and systems for efficiently separating, compacting, and containing collected dust, dirt, or lint. This often involves multi-stage filtration, cyclonic separation, or specialized disposal mechanisms to improve air quality and ease of maintenance.
Design and material innovations for specific cleaning components or attachments, such as brush rolls, mop pads, scrapers, or multi-functional surface tools. These are often tailored for particular surfaces, debris types, or cleaning tasks to enhance effectiveness.
