Laundry treatment agent dispensing assembly for use in laundry treatment device, and laundry treatment device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clothing treatment devices, such as washing machines, have inconvenient detergent dispensing systems that require significant user effort, leading to a poor user experience due to the large volume of detergent boxes and the resulting operational difficulties.
Innovation Solution
A clothing treatment agent dispensing assembly with a split structure, featuring a storage container and a dispensing container connected via a liquid guiding tube, where the dispensing container is slidably connected to the body, and a sealing member is used to prevent leakage and facilitate easy operation, including a telescopic tube to ensure smooth movement and a push switch for locking and unlocking the dispensing container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the detergent box volume is increased to provide sufficient detergent capacity, then the detergent storage capacity is improved, but the user effort required to pull and push the detergent box increases significantly
Solution Approach 1:
The detergent dispensing system is divided into two separate containers: a storage container that remains fixed in the body and a dispensing container that is slidably connected and can be easily removed. The storage container holds the bulk detergent supply while the dispensing container is positioned for user access. This segmentation allows the large-capacity storage container to remain stationary (avoiding user effort issues) while the smaller dispensing container can be easily handled by users.
Solution Approach 2:
The dispensing container is extracted as a separate, independently movable component from the storage container. By taking out the dispensing function into a separate container that can be slid in and out, the system allows users to access and operate only the lightweight dispensing container rather than having to handle the entire large-volume detergent box.
2Ease of operation
If the detergent box is made compact to improve ease of operation, then the user effort is reduced, but the detergent storage capacity decreases
Solution Approach 1:
The dispensing container is designed to nest within or alongside the storage container structure. The dispensing container can be positioned within the overall detergent dispensing assembly, allowing efficient space utilization. This nesting arrangement enables the system to maintain a compact footprint while providing both sufficient storage capacity in the fixed container and easy access to the dispensing container.
3Reliability
If the liquid guiding tube is made long to connect the dispensing container and storage container when the dispensing container is removed, then the liquid flow path is maintained, but the risk of the tube coming out of the storage container increases
Solution Approach 1:
The liquid guiding tube is pre-configured with sufficient length and proper routing to maintain connection between the dispensing container and storage container throughout the dispensing container's movement range. The tube is designed in advance to accommodate the sliding motion, ensuring liquid flow continuity is maintained without requiring additional length that would cause tangling or disconnection issues.

AI summary
A laundry treatment agent dispensing assembly for use in a laundry treatment device, and a laundry treatment device including a body; the laundry treatment agent dispensing assembly includes a storage container fixed to the body, a dispensing container slidably connected to the body, and a liquid guiding cannula; one end of the liquid guiding cannula is communicated with the dispensing container, and the other end of the liquid guiding cannula is inserted into the storage container; the length of the liquid guiding cannula is set so that the other end of the liquid guiding cannula does not go out of the storage container when the dispensing container moves away from the storage container; when a laundry treatment agent is added, it is only needed to pull the dispensing container from the body, and the liquid guiding cannula enables the dispensing container to be communicated with the storage container.
