Drawer Microwave Oven Flow Directing Assembly Vapor Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In drawer-type microwave ovens, the slide rails and driving motor are prone to damage due to high-temperature water vapor generated during heating, leading to reduced operational lifespan.
Innovation Solution
A flow directing assembly is integrated to divert high-temperature water vapor away from the slide rails and driving motor, using air outlets and guide covers to direct vapor discharge outside the oven, reducing erosion and ensuring long-term normal operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the slide rails and driving motor are disposed in the space between the side wall of the cooking cavity and the side wall of housing of the cooker body, then the control system can precisely control the driving motor and drive the slide rails to move accurately, but the slide rails and the driving motor are prone to damage due to high-temperature water vapor erosion after long-term operation
Solution Approach 1:
The patent divides the internal space into two distinct regions: a first spacing region where high-temperature water vapor is discharged, and a second spacing region where the slide rails and driving motor are located. This spatial segmentation prevents the harmful vapor from contacting the mechanical components, resolving the contradiction between control precision and operational reliability.
Solution Approach 2:
The patent extracts the driving motor from the high-temperature vapor environment by placing it in the second spacing region, separated from the first spacing region where vapor is discharged. This extraction protects the motor from thermal erosion while maintaining its control functionality, thus improving operational reliability without sacrificing control precision.
2Object-generated harmful factors
If the high-temperature water vapor is discharged into the space between the side wall of the cooking cavity and the side wall of housing of the cooker body, then the vapor can be vented outside, but the vapor will erode the slide rails and driving motor leading to damage
Solution Approach 1:
The patent segments the vapor discharge path from the mechanical component area by creating separate spacing regions. The first spacing region handles vapor discharge while the second spacing region houses the protected components, effectively separating the harmful vapor flow from vulnerable parts.
Solution Approach 2:
The patent introduces an intermediary structure (the separated spacing regions and associated discharge channels) that mediates between the vapor source and the external environment, preventing direct contact between hot vapor and the slide rails and driving motor while still allowing vapor to be vented outside.
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 prevents damage to the slide rails and driving motor by redirecting high-temperature vapor, allowing for prolonged, uninterrupted operation of the microwave oven.
Implementation Method 1
a flow directing assembly, an air inlet end of the flow directing assembly being in communication with the air outlet mesh, and an air outlet end of the flow directing assembly being arranged at a bottom of the first spacing region
Data Source
AI summary
The present disclosure relates to a drawer-type microwave oven including a cooker body, a door, a front plate, a first slide rail, a second slide rail, a driving motor and a flow directing assembly. An air inlet end of the flow directing assembly is in communication with an air outlet mesh, and an air outlet end of the flow directing assembly is arranged at the bottom of a first spacing region. When the above drawer-type microwave oven works, the high-temperature water vapor inside the cooking cavity is discharged into the flow directing assembly through the air outlet mesh, and is directed and discharged to the bottom of the first spacing region by the flow directing assembly, and then flows along a bottom of the cooking cavity, and is discharged to the outside of the cooker body through a front side air outlet hole.
