Pressure Flushing System with Segmented Water and Gas Chambers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure flushing systems for toilets have large volume and inconvenient installation due to integrated water and air chambers, which occupy significant space and complicate installation.
Innovation Solution
The system divides the pressure water tank into two independent containers, a water chamber and a water-gas mixing chamber, with a communicating member to compress and store gas, allowing for efficient water discharge and pressure relief, and includes a manual control valve for energy savings and overpressure protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the water chamber and air chamber of the pressure water tank are integrated, then the structure is compact, but the volume is large and installation is inconvenient
Solution Approach 1:
The pressure water tank is divided into a water chamber (first container) and an air chamber (second container) that are structurally separate but functionally connected through a communicating member. This segmentation allows each chamber to be optimized independently and reduces the overall volume compared to a fully integrated design.
Solution Approach 2:
The communicating member extends into the interior of the second container, with its second end positioned near the bottom part of the second container. This nested arrangement allows the communicating member to occupy space within the air chamber without increasing the external dimensions of the pressure water tank.
2Power
If the pressure water tank is placed in a ceramic space behind the seat, then the flushing effect is strong, but the installation space is encroached and installation becomes inconvenient
Solution Approach 1:
By segmenting the pressure water tank into separate water and air chambers, the overall volume is reduced, allowing the tank to fit into the limited ceramic space behind the toilet seat without encroaching on the installation space of other components.
Solution Approach 2:
The communicating member extends vertically into the air chamber, utilizing the vertical dimension to establish communication between chambers without requiring additional horizontal space, thus preserving installation space in the ceramic compartment.
3Power
If a large amount of water is used for flushing, then the flushing effect is achieved, but water consumption increases
Solution Approach 1:
The system utilizes pneumatic pressure from compressed air in the air chamber to force water through the drain, creating a strong flushing effect without requiring a large volume of water. The pressure energy from the compressed gas replaces the need for gravitational potential energy from elevated water storage.
Solution Approach 2:
The system changes the energy parameter from gravitational potential energy (height-based) to pressure energy (compression-based). By compressing air to high pressure, the system achieves strong flushing force with reduced water quantity, as the pressure differential drives rapid water discharge.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces the overall volume, facilitates flexible and convenient installation, and enhances the flushing efficiency while providing energy savings and overpressure protection, making it suitable for toilets with small volume requirements.
Implementation Method 1
Gas in the first container and the second container is gradually compressed and stored in an upper part of the second container during a water intake process
Implementation Method 2
the pressure energy accumulated by the compressed gas in the pressure water tank is used to make the water in the pressure water tank generate a strong flushing force when released
Implementation Method 3
Water flows into the first container from the first water inlet, and the water from the first container flows into the second container through the communicating member
Implementation Method 4
The pressure flushing system further comprises a drain valve which is arranged in the first container to open or close the drain
Implementation Method 5
The overpressure protection assembly is arranged relative to the pressure relief hole and closes the pressure relief hole, and opens the pressure relief hole when pressure of the water inlet cavity is greater than a preset value
