Low-Mounted Detergent Module With Pumped Anti-Clog Washer Feed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treating apparatuses are inconvenient due to the elevated position of the detergent storage unit, requiring users to lift detergents to a high location, and are prone to detergent clogging in the supply flow channel.
Innovation Solution
A laundry treating apparatus with a detergent supply module positioned at a lower level, utilizing a detergent supply conduit and pump to efficiently deliver detergent to the tub, and a water supply unit to rinse the conduit, preventing clogging and ensuring consistent detergent delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the detergent storage unit is positioned at the upper portion of the laundry treating apparatus, then the detergent can be stored in a compact space, but the user experiences inconvenience when introducing detergent due to the high position
Solution Approach 1:
The patent inverts the conventional detergent storage position from the upper portion to the lower portion of the laundry treating apparatus. The detergent storage unit is now located at the lower front side, allowing users to easily introduce detergent without lifting, while the detergent is automatically supplied upward to the tub through a supply conduit and pump mechanism.
2Device complexity
If the detergent storage unit is positioned at the upper portion, then the structure is compact, but detergent may clog in the supply flow channel due to gravity
Solution Approach 1:
The patent replaces the gravity-dependent detergent flow mechanism with an active pumping system. A detergent supply pump is installed to actively pump detergent from the lower storage unit through the supply conduit to the tub, ensuring reliable detergent delivery regardless of the inverted storage position and preventing clogging issues.
Solution Approach 2:
The patent utilizes hydraulic principles by employing a pump to create controlled fluid flow of detergent through the supply conduit. The pump generates the necessary pressure to move detergent upward from the lower storage position to the tub, ensuring consistent and clog-free delivery.
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 lowered detergent storage position reduces user inconvenience, facilitates easy detergent supply, and prevents flow channel clogging, ensuring a constant detergent amount is delivered during washing.
Implementation Method 1
a detergent pump provided to the detergent supply conduit to move the liquid detergent in the container to the tub
Implementation Method 2
a water supply unit to supply washing water to the tub and to rinse the detergent supply module using the washing water supplied to the tub
