Upper-Space Heat Pump Layout for Shorter Flue and Faster Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing and drying machines with heat pump mechanisms face challenges in achieving faster air circulation and larger air volume due to longer circulatory ventilation flues, leading to longer drying times and increased power consumption.
Innovation Solution
The design relocates the heat pump device and filter to the upper space within the machine, creating a shorter circulatory ventilation flue and allowing for efficient air regulation, which enhances air circulation and heat exchange efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the heat pump mechanism is disposed in the lower space of the housing, then the structure is stable and components are easily accessible, but the circulatory ventilation flue becomes longer which increases pressure loss and reduces air circulation efficiency
Solution Approach 1:
The patent relocates the heat pump mechanism from the lower space to the upper space of the housing, changing its spatial position to reduce the length of the circulatory ventilation flue. This dimensional repositioning directly addresses the contradiction by shortening the air circulation path while maintaining component accessibility through proper upper space configuration.
2Stability of the object's composition
If the circulatory ventilation flue is made longer to accommodate heat pump in lower space, then structural stability is improved, but pressure loss of dry air increases and drying efficiency decreases
Solution Approach 1:
By moving the heat pump mechanism to the upper space, the patent changes the spatial arrangement to minimize flue length and reduce pressure loss. The upper space configuration maintains structural stability while optimizing the air circulation path for energy efficiency.
3Ease of manufacture
If the heat pump mechanism is placed in the lower space, then installation is simplified, but the circulatory volume of dry air is reduced and drying time increases
Solution Approach 1:
The patent resolves this contradiction by repositioning the heat pump mechanism to the upper space, which shortens the circulatory ventilation flue and increases the circulatory volume of dry air. This spatial change accelerates the drying process while installation procedures for upper space configuration remain straightforward.
