Dehumidifying kit, drying apparatus comprising same, and method for operating dehumidifying mode of drying apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drying apparatuses face challenges in efficiently dehumidifying external air when the door is open, as dry air discharged from the exhaust port can be sucked back into the suction port, reducing dehumidification performance.
Innovation Solution
A dehumidifying kit is installed on the drying apparatus, which partitions the opening part and inner space to create separate air flow paths for external air suction and dry air discharge, preventing dry air from mixing with moist external air and enhancing dehumidification efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the door of the drying apparatus is opened to dehumidify external air, then the external air dehumidification function is enabled, but dry air discharged from the exhaust port is sucked back into the suction port, lowering dehumidification performance
Solution Approach 1:
The opening part is divided into two distinct regions: an opening inlet for external air intake and an opening outlet for dry air discharge. This segmentation prevents the mixing of moist external air with discharged dry air, ensuring that the suction port only draws in fresh moist air for dehumidification while the exhaust port releases dry air to the outside, thereby maintaining high dehumidification performance
Solution Approach 2:
A partition wall is introduced as an intermediary structure within the opening part to physically separate the air intake and discharge paths. The partition wall creates distinct flow channels that guide external air toward the suction port and direct discharged dry air toward the exhaust port, preventing recirculation and ensuring efficient dehumidification operation
2Productivity
If a separate exhaust port and flow path switching means are added to prevent dry air recirculation, then dehumidification performance is improved, but device complexity increases
Solution Approach 1:
The partition wall integrates multiple functions into a single structure: it separates the opening part into inlet and outlet regions, guides airflow patterns, and prevents dry air recirculation all at once. This merging eliminates the need for separate flow path switching dampers or additional exhaust ports, achieving high dehumidification performance while maintaining simple device structure
Solution Approach 2:
The partition wall serves multiple purposes simultaneously: it acts as a physical barrier to separate air streams, a flow guide to direct air movement, and a structural element that maintains pressure differentials. This multi-functionality allows the system to achieve effective dehumidification without adding complex flow path switching mechanisms

Function Achieved in This Case
The dehumidifying kit effectively prevents dry air recirculation, improving the external air dehumidification performance of the drying apparatus and ensuring efficient moisture removal from external air.
Implementation Method 1
an opening part of the drying apparatus is partitioned as an opening inlet and an opening outlet, an inner space of the drying apparatus is partitioned as an external air suction flow path from the opening inlet to the suction port and a dry air discharge flow path from the exhaust port to the opening outlet
