Toilet Suction System for Rapid Odor Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bathroom ventilation systems are inadequate for quickly removing odors and humidity, often requiring manual operation, leading to discomfort and inefficiency, and previous solutions have been structurally invasive, aesthetically poor, and economically unviable.
Innovation Solution
A suction system for bathrooms that automatically extracts odors and humidity from the toilet flushing pipe and the room, featuring a centrifugal extractor connected to a draining mechanism that eliminates water residues, allowing for efficient odor removal and integration into existing plumbing systems, with a flow diverter and sensors for optimized operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional extractor is used to ventilate the bathroom, then air can be drawn from the room, but the time needed to extract enough air is considerable and organic odors cannot be rapidly removed
Solution Approach 1:
The invention extracts organic odors directly from the toilet bowl using a suction system with a nozzle positioned near the bowl, separating the odor extraction function from general room ventilation. This allows rapid removal of odors at their source without waiting for complete air exchange in the room.
Solution Approach 2:
The patent uses water from the flushing pipe as an intermediary medium to carry organic odors from the toilet bowl to the extractor. The water flow picks up odors and transports them through a channel to the suction system, enabling rapid odor removal independent of room air exchange time.
2Object-affected harmful factors
If windows and doors are opened for ventilation, then bad odors and humidity can be eliminated, but the temperature of the room decreases in winter and increases in summer causing physical discomfort and economic waste
Solution Approach 1:
The invention extracts harmful factors (odors and humidity) directly from their sources using localized suction systems - odors from the toilet bowl and humidity from strategic positions in the room. This eliminates the need for opening windows and doors for ventilation, thereby maintaining stable room temperature and avoiding thermal discomfort.
3Ease of operation
If extractor means are provided on the ceiling or wall controlled manually by light switch, then air can be drawn from the room, but the system is not ideal for solving bad odor problems and requires considerable time
Solution Approach 1:
The invention implements automated control where sensors detect the presence of users and automatically activate the appropriate extraction systems. The system serves itself by detecting conditions (user presence, odor levels, humidity) and activating without manual intervention, improving both ease of operation and extraction efficiency.
Solution Approach 2:
The patent incorporates sensors that provide feedback about room conditions (presence detection, odor detection, humidity levels) to the control system. This feedback mechanism allows the system to automatically adjust operation to match actual needs, improving productivity while maintaining simple operation through automation.
4Productivity
If suction systems are designed with complex structural shapes to extract odors from toilet bowl, then odor extraction may be improved, but the systems become structurally invasive, aesthetically poor, and difficult to install and maintain
Solution Approach 1:
The invention divides the suction system into separate functional modules: an extractor unit, a control unit, and a drainage integration component. This segmentation allows each component to be optimized independently and installed separately, reducing overall structural invasiveness while maintaining extraction capability.
Solution Approach 2:
The patent designs the suction system to serve multiple functions: extracting odors from the toilet bowl, extracting humidity from the room, and integrating with existing drainage systems. This multi-functionality reduces the need for separate systems and complex installations, simplifying both structure and maintenance while maintaining high productivity.

AI summary
A suction system which comprises extractor means (11) which are functionally connected in input to a flushing pipe (12) of a flusher of a toilet bowl (14) and in output to a space located outside the room in which the bowl (14) is provided. The extractor means (11) comprise a box-like container (21, 121 ), which is provided with an inspection cover (22) and inside which there is a compartment (23) for accommodating an extractor (24) in which the intake port (25) is connected to the flushing pipe (12, 112) of the flusher and the discharge port (26) is connected to a pipe (15) for connection to the space outside the room (for example the wastewater drain or vent stacks) or other vents; electrical and electronic means (42) for supplying power and managing the system are provided within the box-like container (21, 121).
