Retractable Vapor Guide for Flush-Mounted Extractor Hoods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Extractor hoods with motorized or spring-loaded vapor deflectors are visually unappealing when retracted, as they protrude and disrupt the uniform appearance of kitchen units, especially when installed in wall cabinets.
Innovation Solution
An extractor hood device with a displacement device comprising a motor, prestressing device, and coupling mechanism that allows the vapor guide to be automatically extended and retracted vertically and horizontally, enabling it to be hidden within the housing or behind a front panel, with optional manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the vapor guide device is made extendable to provide a large suction area, then the fume extraction efficiency is improved, but the device protrudes and disrupts the uniform appearance of kitchen units when retracted
Solution Approach 1:
The vapor guide device is designed to be dynamically extendable and retractable. During cooking operations, the vapor guide extends forward to provide a large suction area for effective fume extraction. When not in use, it retracts to maintain a flush appearance with the kitchen cabinet front panel, thus resolving the contradiction between functional area and aesthetic appearance.
Solution Approach 2:
The vapor guide device is nested within the housing structure when retracted. The guide can be stored inside the cabinet body or integrated into the housing, allowing it to disappear from view when not needed, while being readily deployable when cooking requires active fume extraction.
2Productivity
If the vapor guide device is positioned closely above the cooking area for effective vapor capture, then the fume extraction efficiency is improved, but the device cannot be concealed when not in use
Solution Approach 1:
The vapor guide device employs dynamic positioning capabilities, allowing it to move between a retracted state (concealed within the housing) and an extended state (positioned closely above the cooking area). This dynamic behavior enables the system to achieve high fume extraction efficiency when needed while maintaining a clean, concealed appearance during non-operational periods.
3Productivity
If the vapor guide device is made fixed and large-area, then the suction performance is improved, but the device is visually unappealing and protrudes below the furniture body
Solution Approach 1:
Rather than using a fixed large-area vapor guide that permanently protrudes, the invention employs a dynamic guide that can extend to provide large suction area during cooking operations and then retract to maintain visual appeal. This dynamic approach allows the system to achieve high suction performance when needed without the penalty of permanent visual disruption to the kitchen unit's appearance.
