Sewage system for a sanitary arrangement and sanitary arrangement

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention is an intelligent wastewater system for sanitary installations—especially showers—that uses an ultrasonic transmitter and receiver as a non-intrusive sensor to monitor the flow and presence of wastewater in pipes. This system can control a wastewater pump more precisely, detecting the water level and the presence of air bubbles via ultrasonic transmission, enabling optimal and energy-efficient pump operation. The design is suitable for retrofitting existing installations without extensive modifications, as the sensors can be clamped onto the exterior of existing pipes or integrated into new piping sections.

Use CasesContent extracted from patent full text and abstract with AI.

• Retrofitting barrier-free, low-floor showers in buildings without sufficient drainage slope.
• Equipping sanitary installations in mobile homes, RVs, boats, or older buildings where gravity drainage is insufficient.
• Accurately controlling pumps in bathtubs, sinks, washing machine drains, or toilet installations.
• Preventing water backup or overflows by intelligent real-time control of pumps based on actual waste water flow and air content.
• Implementing maintenance-free and long-lasting monitoring of wastewater systems without the sensor coming into contact with contaminated water.
• Smart-home integration for water usage monitoring and status reporting from bathrooms or utility rooms.

BenefitsContent extracted from patent full text and abstract with AI.

• Enables installation of showers and sanitary fixtures where traditional gravity wastewater drainage is not feasible (e.g., renovations, mobile units).
• Allows for energy-efficient and quiet operation of wastewater pumps by adjusting pump speed based on real-time water/air detection.
• Reduces the risk of blockages, overflows, and water damage due to improperly controlled wastewater flows.
• Sensors are mounted outside the pipe, avoiding contact with wastewater and preventing corrosion, fouling, and reducing maintenance needs.
• Easy to retrofit or implement in existing and new systems (clamp-on or modular design), minimizing disruption and installation time.
• Accurate measurement allows for reliable detection of water, air, and foam, improving the user experience (e.g., constant drainage during showers).
• Supports smart automation and can be adapted for a range of sanitary installations beyond just showers.

Patent Abstract

The invention relates to a waste water system for a sanitary arrangement, in particular for a shower arrangement, wherein the waste water system has an ultrasonic transmitter and an ultrasonic receiver, which together form a waste water sensor, wherein the waste water system can further comprise additional components such as a waste water pump and/or a pump control. The invention also relates to a sanitary arrangement, in particular a shower arrangement, having such a waste water system.
