Dispensing Device Hose Guide Structure for Laundry Machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices in washing machines suffer from hose wear and obstruction issues due to the hose's inability to be fixed within the housing, leading to detergent leakage and poor user experience.
Innovation Solution
A dispensing device with a deformable hose featuring a folding portion that includes guide tubes and limiting portions to guide the hose, enhancing the hose's position and movement, reducing wear, and reducing hose wear and obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a long hose is installed within the housing to connect the dispensing pump and the liquid storage box, then detergent leakage is prevented, but the hose cannot be fixed and suffers severe wear during liquid storage box withdrawal
Solution Approach 1:
The patent uses a flexible hose with a specific structure (including an inner tube and outer tube) to maintain reliability while accommodating movement. The flexible structure allows the hose to bend and extend during liquid storage box withdrawal without breaking, preventing detergent leakage while reducing wear through its inherent flexibility and protective outer layer.
Solution Approach 2:
The patent introduces a guide structure as an intermediary element between the hose and the housing. This guide structure includes guide grooves and guide blocks that constrain the hose's movement path, ensuring it moves in a controlled manner during liquid storage box withdrawal, thereby reducing unnecessary wear while maintaining its leakage-prevention function.
2Ease of operation
If a long hose is installed within the housing to allow liquid storage box withdrawal, then connection is maintained, but the hose hinders withdrawal and cannot be fixed
Solution Approach 1:
The flexible hose design allows the liquid storage box to be withdrawn smoothly without disconnection. The hose's flexibility accommodates the movement while maintaining the fluid connection, making the operation easy without requiring complex rigid piping arrangements.
Solution Approach 2:
The guide structure acts as an intermediary that simplifies the hose arrangement by providing a defined movement path. This reduces the complexity of hose management during withdrawal, as the guide grooves and blocks automatically direct the hose's movement without requiring complex routing or additional fixation mechanisms.

AI summary
The present invention provides a dispensing device, comprising a housing, a side of which is provided with a connector for dispensing detergent, a liquid storage box provided in the housing that can be pulled out and placed from the side, the liquid storage box and the connector being connected via a dispensing pump and a hose, the hose is deformable for taking out the liquid storage box, and a folding portion provided on the hose for guiding its deformation. By providing a folding portion on the hose, the present invention can guide the position and range of motion of the hose between the liquid storage box and the connector, and at the same time, can improve the guidance of the deformation position and deformation amplitude of the hose, thereby improving the controllability of the hose deformation, reducing the obstruction of the hose to the pulling out of the liquid storage box, and at the same time, can reduce the wear on the hose caused by long-term pulling out, thereby improving the user experience and increasing the service life of the hose. The present invention also provides a washing machine equipped with the dispensing device.
