Solution Overview
Problem
Conventional humidifiers face issues with cleanliness due to stagnant water, contamination from fine dust, and inefficient air mixing, leading to unsanitary and overheated humidified air.
Innovation Solution
A humidifier design that separates and combines humidification and cleaning flow paths, optimizes air mixing, and incorporates a heating flow path to improve air heating and humidification efficiency, while minimizing flow resistance and guiding air in a specific direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a monolithic flow path is used for humidified air, then the structure is simple, but the air cleanliness is poor due to mixing with stagnant water vapor
Solution Approach 1:
The flow path is divided into separate segments: a first flow path for clean air intake and a second flow path for water vapor removal. This segmentation prevents mixing between clean air and stagnant water vapor, improving air cleanliness while maintaining structural simplicity through functional separation.
2Temperature
If the heater operates continuously, then the temperature control is stable, but the energy consumption is excessive
Solution Approach 1:
The heater operates periodically rather than continuously, with control logic that adjusts heating cycles based on detected temperature and humidity levels. This periodic operation maintains stable temperature control while significantly reducing energy consumption compared to continuous operation.
3Object-affected harmful factors
If separate humidification and heating flow paths are used, then the air cleanliness is improved, but the device complexity increases
Solution Approach 1:
The separate humidification and heating flow paths are merged into a unified discharge flow path that combines clean air and heated air before discharge. This merging approach maintains the cleanliness benefits of separate paths while reducing overall device complexity through flow path integration.
4Device complexity
If a single flow path is used for air discharge, then the device structure is simple, but the mixing of humidified air and clean air is inefficient
Solution Approach 1:
The flow paths are arranged in different spatial dimensions and directions, with the first flow path introducing clean air from one direction and the second flow path introducing humidified air from another direction. This multi-dimensional arrangement enhances mixing efficiency while maintaining a simple overall device structure.

AI summary
The present disclosure relates to a humidifier. A humidifier according to one aspect of the present disclosure includes: an outer case with an intake opening; a discharge opening that opens to the outside of the outer case; an inner case spaced inward from the outer case; a fan disposed inside the outer case; a humidification assembly disposed inside the inner case and positioned downstream from the fan, that includes a humidification device internally having a space; a air flow path formed between the outer case and the inner case, that extends toward the discharge opening; and an inlet that branches off from the air flow path and allows a space between the outer case and the inner case and the internal space of the humidification device to communicate with each other. Thus, part of blown air can be admitted into the humidification device and then sprayed.
