Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In heat pump dishwashers, the accumulation of condensed water in the installation cavity can lead to rust and affect the operation of electrical components, posing a safety hazard.
Innovation Solution
A heat pump dishwasher design that includes a chassis with a liquid collecting groove at the upper side, where the evaporator and compressor are installed. The compressor is positioned to release heat, evaporating the condensed water and preventing long-term accumulation, which reduces corrosion risks and maintains electrical component functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the heat pump system operates in the installation cavity, then heat transmission efficiency is improved, but condensed water accumulates causing rust and safety hazards
Solution Approach 1:
The patent utilizes the waste heat generated by the compressor during heat pump operation to evaporate the condensed water that accumulates in the installation cavity. By positioning the compressor within the installation cavity, the harmful condensed water is converted into a beneficial evaporation process, eliminating rust and safety hazards while maintaining heat transmission efficiency.
2Ease of operation
If the compressor is installed in the installation cavity, then condensed water evaporation is improved, but the compressor may be affected by condensed water
Solution Approach 1:
The patent introduces a heat dissipation component as an intermediary between the compressor and the condensed water. This component serves dual functions: it facilitates heat transfer from the compressor to evaporate condensed water, while simultaneously protecting the compressor from direct contact with condensed water, thus maintaining both evaporation efficiency and compressor reliability.
3Volume of stationary object
If electrical components are installed in the installation cavity, then space utilization is improved, but rust and operational issues occur due to condensed water
Solution Approach 1:
The patent applies the same principle to electrical components: the waste heat from the compressor is used to evaporate condensed water, thereby protecting the electrical components from rust and operational issues. This allows electrical components to be safely installed in the installation cavity, maximizing space utilization while eliminating reliability concerns.
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
The solution effectively collects and evaporates condensed water, preventing corrosion and ensuring the safe operation of electrical components within the heat pump dishwasher.
Implementation Method 1
the compressor is installed at the liquid collecting groove... the compressor is positioned to release heat, evaporating the condensed water
Implementation Method 2
Heat transmission usually occurs when the heat pump dishwasher operates, and the water vapor of the air in the installation cavity will be liquefied into the condensed water during the heat transmission
