Solution Overview
Problem
Conventional range hoods with electrostatic absorption apparatuses pose hidden dangers due to high-voltage direct current power supply wires, which can be shorted or contact humans, leading to safety risks.
Innovation Solution
The range hood design eliminates the need for a high-voltage direct current power supply wire by integrating the high-voltage power supply module as a partial wall of the accommodation cavity, allowing for easy insertion connection between the electrostatic absorption apparatus and the power supply module, with a plug-and-socket system and insulation isolation walls to reduce creepage phenomena, and using a mains or low-voltage direct current power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a high-voltage direct current power supply wire is used to connect the power supply module and the electrostatic absorption apparatus, then power can be transmitted, but safety risks arise from potential shorting or direct contact with human body
Solution Approach 1:
The patent combines the power supply module and the electrostatic absorption apparatus into a single integrated unit. The power supply module is directly mounted on the housing structure, and the electrostatic absorption apparatus is positioned adjacent to it, eliminating the need for external high-voltage wiring. This merging of components resolves the safety issue by removing the exposed power supply wire while maintaining the necessary electrical connection through integrated terminals.
2Reliability
If the high-voltage power supply module and electrostatic absorption apparatus are integrated, then safety is improved and structure is compacted, but insertion connection complexity increases
Solution Approach 1:
The patent segments the electrostatic absorption apparatus into a removable module that can be independently installed and maintained. The apparatus includes a housing with an opening that allows it to be inserted into the range hood structure and connected to the power supply module through mating terminals. This segmentation enables easy installation and removal while ensuring safe electrical connection through the integrated terminal design.
