Detergent Box Slanted Surface and Check Valve for Complete Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drum-type washing machines face issues with detergent leakage due to low coupling force between the detergent box and pump, incomplete detergent discharge, and difficulty in cleaning the detergent box, which affects convenience and efficiency.
Innovation Solution
The design includes a detergent box with a through-hole at its lowermost position, a check valve for one-way detergent flow, and a removable configuration to enhance coupling force and sealing performance, allowing complete detergent discharge and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detergent box is integrally provided with a check valve, then the sealing structure is complete, but the detergent box cannot be easily cleaned
Solution Approach 1:
The check valve is designed as a separable component that can be removed from the detergent box, allowing the box to be disassembled for cleaning while maintaining sealing performance when assembled
2Reliability
If the detergent box has a sealing structure at the detergent supply port, then detergent leakage is prevented, but the elastic member is separated due to elastic force during vibration
Solution Approach 1:
The sealing member is designed to dynamically adapt to vibrations and movements during washing operations, maintaining sealing contact through flexible material properties and geometric design that accommodates elastic deformation
3Device complexity
If the detergent pump has low coupling force with the detergent box, then the structure is simple, but detergent leaks through the gap between them
Solution Approach 1:
A flexible sealing ring is installed at the coupling interface between the detergent pump and detergent box, creating a deformable seal that maintains contact under varying conditions and prevents detergent leakage through the gap
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
This solution increases the coupling force between the detergent box and pump, ensures complete detergent discharge, and facilitates easy cleaning of the detergent box, improving user convenience and operational efficiency.
Implementation Method 1
a check valve for one-way detergent flow
Implementation Method 2
a through-hole formed in a rear side of the body to allow the detergent to flow out therethrough, and wherein the body includes a lower surface including a first slanted surface, the first slanted surface being slanted downwards from a front side of the body toward the rear side of the body

AI summary
A laundry treatment apparatus is disclosed. The laundry treatment apparatus includes a cabinet, a tub disposed in the cabinet to provide a washing space, a drum rotatably disposed in the tub to receive laundry placed therein, a detergent pump for supplying detergent to the tub, and a detergent box removably mounted to the detergent pump and configured to contain the detergent. The detergent box includes a body for providing a space containing the detergent and a through-hole formed in a rear side of the body to allow the detergent to flow out therethrough. The body includes a lower surface including a first slanted surface, which is slanted downwards from a front side of the body toward the rear side of the body. The through-hole is located at the lowermost position of the body.
