Laundry treatment apparatus
Solution Overview
Problem
Conventional laundry treatment apparatuses suffer from uneven brightness in the treatment space, making it difficult to detect foreign substances and causing glare issues due to the light emitting unit's design.
Innovation Solution
A laundry treatment apparatus with a light source and light guide integrated into a holder of a support body, using a bar-shaped light guide with a slit through hole and diffusion grooves to ensure even illumination across the treatment space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light emitting unit is provided to emit light from an upper surface to a bottom surface of the treatment space, then the treatment space can be illuminated, but the brightness of the entire treatment space cannot be evenly maintained
Solution Approach 1:
The light emitting unit is divided into multiple light emitting units arranged along the width direction of the treatment space. Each light emitting unit independently illuminates a specific region, allowing for even distribution of light across the entire treatment space, thereby resolving the brightness uniformity issue while maintaining detection capability.
2Illumination intensity
If a light emitting unit is provided to emit light from an upper surface to a bottom surface of the treatment space, then the treatment space can be illuminated, but glare to the user may occur
Solution Approach 1:
Each light emitting unit is equipped with a light guide that directs light locally to specific regions. The light guide has a light emitting surface that faces the treatment space, controlling the direction and distribution of light to illuminate the treatment space effectively while preventing direct light from reaching the user's eyes, thus eliminating glare.
3Illumination intensity
If multiple light emitting units are arranged along the width direction of the treatment space, then even brightness can be achieved, but the device complexity increases
Solution Approach 1:
Multiple light emitting units and their corresponding light guides are integrated into a unified holder structure. The holder supports both the light emitting units and light guides in fixed positions, merging the lighting components into a single assembled unit. This reduces overall device complexity while maintaining even brightness distribution across the treatment space.
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 provides even brightness throughout the treatment space, preventing glare and facilitating the detection of foreign substances, while also offering indirect, soft lighting for aesthetic benefits.
Implementation Method 1
a light guide part provided in a bar shape within the holder body to transmit light supplied from the light source in a length direction of the through hole
Implementation Method 2
a diffusion part provided to the light guide part to diffuse light supplied from the light source into the light guide part

AI summary
A laundry treatment apparatus includes a treatment space to provide a space for accommodating the laundry therein, a supply device supplying at least one of air or steam to the treatment space, a holder fixed to each of the first side surface and the second side surface, and a support body supported by the holder to divide the treatment space into an upper space and a lower space. The holder may include a holder body fixed to the first side surface or the second side surface, a through hole provided in one surface of the holder body facing the first or second side surface having the holder body fixed thereto, a light source provided inside the holder body, and a light guide provided in a bar shape within the holder body to transmit light supplied from the light source in a length direction of the through hole.
