Solution Overview
Problem
Conventional washing and drying machines are limited in operating at high liquid pressures and temperatures, and they cannot perform washing and drying cycles in a minimum time without using a conventional pump.
Innovation Solution
A pneumatic washing and drying machine using compressed air or gas to bring liquid from a reservoir to the washing chamber and then to spray nozzles, allowing for high-pressure and high-temperature operations, with recirculation of the fluid for efficient washing and drying, and utilizing carboys with control systems to manage the flow of liquid and air for optimized cycle times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional water pump is used to send liquid from the liquid reservoir to the washing chamber, then the machine structure is simple and easy to manufacture, but the machine cannot operate at high liquid pressures and temperatures
Solution Approach 1:
The patent applies pneumatic means powered by compressed air to replace the conventional water pump. The compressed air supply system uses pneumatic principles to pressurize and transport liquid from the liquid reservoir through spray nozzles to the washing chamber, enabling high-pressure and high-temperature operations that conventional pumps cannot achieve.
2Productivity
If a conventional water pump is used, then the device structure is simple, but the washing and drying cycle time is extended and cannot be performed in minimum time
Solution Approach 1:
The pneumatic means utilizing compressed air enables rapid pressurization and delivery of liquid to the washing chamber, significantly reducing the time required for washing and drying cycles compared to conventional pump systems.
Solution Approach 2:
The system pre-pressurizes the liquid using compressed air before delivery to the washing chamber, allowing immediate high-pressure spraying when needed, thus reducing cycle time without requiring complex high-pressure pumps.
3Stress or pressure
If compressed air is used to bring liquid to the washing chamber, then high liquid pressures and temperatures can be achieved, but the device complexity increases
Solution Approach 1:
The patent employs a compressed air supply connected to pneumatic means that directly pressurize and deliver liquid through spray nozzles to the washing chamber. This pneumatic-hydraulic system achieves high liquid pressures and temperatures while maintaining relatively simple device architecture compared to conventional high-pressure pump systems.
