Efficient Heat Transfer in Surface Cleaning Devices
Here’s PatSnap Eureka !
Summary
Problems
Conventional surface cleaning devices, such as carpet extractors, often inefficiently heat and maintain cleaning fluids, leading to suboptimal cleaning performance and fluid temperature regulation.
Innovation solutions
A portable surface cleaning apparatus with a motor/fan assembly that generates airflow to transfer heat from heated air to the cleaning fluid, utilizing a duct with an undulating profile for enhanced heat exchange, allowing for effective heating and temperature regulation of the cleaning fluid.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If conventional heating methods are used for cleaning fluid, then heating can be achieved, but energy efficiency is poor and temperature regulation is suboptimal
Why choose this principle:
The patent converts the waste heat generated by the motor/fan assembly into a useful heating source for the cleaning fluid. The motor/fan assembly generates heat as a byproduct of operation, which would otherwise be wasted, but the patent captures this heat through the heat exchange duct and uses it to heat the cleaning fluid in the supply tank, thereby converting a harmful waste product into a beneficial resource.
Principle concept:
If conventional heating methods are used for cleaning fluid, then heating can be achieved, but energy efficiency is poor and temperature regulation is suboptimal
Why choose this principle:
The system uses its own operational byproducts (heated air from motor/fan operation) to serve its own heating needs. The motor/fan assembly and supply tank work together in a self-sufficient manner where the heat generated during normal operation automatically heats the cleaning fluid without requiring external heating equipment or additional energy input.

Abstract
A cleaning apparatus for a floor surface comprises a fluid delivery system having a supply tank for storing cleaning fluid and a fluid distributor for delivering the cleaning fluid to a surface to be cleaned. An air pathway is provided in the cleaning apparatus for removing heated air from the motor. In operation, heat from the heated air is transferred to the cleaning fluid in the supply tank.
