Solution Overview
Problem
Conventional clothes washing methods in electric appliances are inefficient in terms of energy consumption and washing time, as they cannot be adapted to different load sizes, leading to suboptimal heating and washing performance.
Innovation Solution
A method that detects the mass of the load and selectively executes either a first heating washing mode, where water is heated with a washing heating tube, or a second heating washing mode, where the wetted load is heated with hot air, optimizing energy use and washing efficiency based on load size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a conventional washing heating mode with a washing heating tube is used to heat water for washing, then the washing process can be completed, but the heating energy consumption is high and the washing time is long when the load mass is small
Solution Approach 1:
The patent changes the heating parameter by switching between two different heating modes (water heating mode and air heating mode) based on the detected load mass. When load mass is small, air heating mode is used with lower energy consumption; when load mass is large, water heating mode is used. This dynamic parameter adjustment resolves the contradiction between energy consumption and washing efficiency.
Solution Approach 2:
The patent implements a dynamic heating system that automatically adjusts the heating mode based on real-time load mass detection. The control unit switches between heating modes dynamically, making the system adaptable to different washing scenarios and resolving the fixed inefficiency of conventional single-mode heating systems.
2Adaptability or versatility
If a single washing heating mode is used for all loads, then the device structure is simple, but the system cannot be adapted to different application scenarios leading to lower washing efficiency
Solution Approach 1:
The patent makes the heating system multi-functional by equipping it with two heating modes (water heating and air heating) that can serve different load sizes. The same heating system structure performs different functions based on the selected mode, achieving universality without requiring completely separate systems for different scenarios.
Solution Approach 2:
The patent incorporates a feedback mechanism where the control unit detects load mass and automatically selects the appropriate heating mode. This closed-loop feedback system allows the heating mode to adapt to actual washing needs, improving versatility while keeping the control logic manageable and the overall system complexity acceptable.
3Temperature
If water is heated using a washing heating tube for small loads, then sufficient heating is achieved, but the energy consumption is unnecessarily high
Solution Approach 1:
The patent changes the heating parameter by selecting air heating mode instead of water heating mode when load mass is small. Air heating requires less energy to reach the necessary temperature for effective washing, thus maintaining heating effectiveness while reducing energy consumption for small loads.
Solution Approach 2:
The patent applies partial heating action by using air heating (less intensive) for small loads where full water heating would be excessive. This partial action approach provides sufficient heating for the actual need without the excessive energy consumption of heating large volumes of water for small loads.
