Laundry treating apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry treating apparatuses face inefficiencies in detergent supply, as liquid laundry detergent is not fully dissolved after washing, leading to remaining detergent in the water tank and increased movement distance, requiring additional water supply valves for efficient distribution.
Innovation Solution
A laundry treating apparatus with a detergent supply apparatus that includes a storage container system, a laundry detergent pump, and a water dispenser, where the detergent input pipe directs detergent directly into the tub, reducing movement distance and eliminating the need for additional water supply valves by integrating detergent and water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If laundry detergent is supplied toward a rear portion of the detergent supply apparatus, then a large amount of laundry detergent can be stored in the detergent supply apparatus, but the movement distance of laundry detergent increases causing difficulty in efficiently supplying laundry detergent
Solution Approach 1:
The patent changes the spatial dimension of detergent supply by introducing a vertical water dispenser structure that allows detergent to be supplied downward through multiple levels. The detergent storage container is positioned at the rear, and detergent flows vertically through the water dispenser's water receiving portions and discharge holes, achieving efficient supply despite the rearward storage position.
2Quantity of substance
If laundry detergent is supplied toward a rear portion of the detergent supply apparatus, then a large amount of laundry detergent can be stored, but additional water supply valves are required for adding laundry detergent
Solution Approach 1:
The water dispenser structure serves multiple functions: it supplies water to the tub, receives laundry detergent from the storage container, and discharges the detergent through its water receiving portions and discharge holes. This multi-functional design eliminates the need for separate water supply valves for detergent addition, simplifying the overall valve structure while maintaining the capability to supply large amounts of detergent.
3Ease of operation
If manual detergent input is allowed, then user convenience is improved, but the structure of the detergent supply apparatus becomes more complex
Solution Approach 1:
The patent merges the manual detergent input function with the existing water dispenser structure. The detergent storage container and water dispenser are integrated, with the detergent discharge pipe connecting to the water dispenser's water receiving portions. This integration allows manual detergent input without requiring separate structural components, maintaining simplicity while improving user convenience.
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
Enables efficient automatic supply of detergent to the tub, simplifies the rear structure of the detergent supply apparatus, and enhances user convenience by allowing direct manual input, reducing assembly complexity and facilitating easy removal of storage containers.
Implementation Method 1
a laundry detergent pump provided at a rear portion of the housing to define a movement of laundry detergent stored in the storage container
Implementation Method 2
a water dispenser fixedly provided inside the main body to allow a bottom portion thereof to face an upper portion of the storage container so as to define a movement of water flowing in from the outside

AI summary
The present disclosure relates to a laundry treating apparatus, including a tub provided inside a main body and a drum rotatably provided inside the tub; and a detergent supply apparatus provided to be inserted into or withdrawn from a front surface of the main body, and configured to supply laundry detergent to the tub, wherein the detergent supply apparatus includes a laundry detergent input pipe that allows laundry detergent being moved by the laundry detergent pump to pass through an upper portion of the wash water dispenser so as to flow into the housing through the wash water dispenser.
