Humidifier Light Source Isolation to Reduce Condensation Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional upward discharge type large-capacity humidifiers face issues with lamp damage due to water spillage and condensation from humidified air, posing safety risks and durability concerns.
Innovation Solution
The design includes a middle tray to capture and redirect spilled water, isolating the light source from the discharge flow path and using a light diffuser to prevent moisture ingress, while the light source is positioned outside the inner shell to avoid direct exposure to humidified air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the lamp is positioned in the middle of the water tank to provide illumination, then the lighting function is achieved, but the lamp is exposed to water spillage and condensation causing damage and safety risks
Solution Approach 1:
The lamp is extracted from the water tank interior and repositioned on the outer circumferential surface of the main body. This separation removes the lamp from the harmful environment of water spillage and condensation while preserving its illumination function through the light transmitting plate.
Solution Approach 2:
The light transmitting plate serves as an intermediary element that allows light to pass through from the lamp positioned outside the water tank to illuminate the interior space. This mediator enables the lighting function while maintaining physical separation between the lamp and water.
2Illumination intensity
If the lamp is exposed to humidified air flow to provide ambient lighting, then the aesthetic effect is enhanced, but condensation forms on the lamp causing damage
Solution Approach 1:
The lamp is extracted from the humidified air flow path and positioned outside the main body. This eliminates direct exposure to condensation-forming conditions while the light transmitting plate maintains the aesthetic ambient lighting effect by allowing light to diffuse through the housing.
3Illumination intensity
If the lamp is positioned inside the water tank for illumination, then the lighting function is achieved, but water spillage causes short circuits posing safety risks
Solution Approach 1:
The lamp is extracted from the water tank interior and repositioned on the outer circumferential surface. This physical separation eliminates the risk of water contact causing short circuits while the light transmitting plate ensures the lighting function remains effective for the water tank area.

AI summary
A humidifier may include a case; a humidifying device which is disposed inside the case, and generates humidified air; and a light source which is disposed inside the case, and emits light, wherein the case includes an inner shell which is disposed above the humidifying device, and in which a first discharge flow path through which the humidified air flows is formed, wherein the light source is disposed outside the inner shell.
