Drum-Mounted Reservoir for Controlled Laundry Product Dissolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machines have limited effectiveness in distributing and dissolving laundry products during the wash cycle, leading to poor product dispersion, damage to linen, and inability to control product introduction timing.
Innovation Solution
A washing machine with a liquid recirculation device and a tank fixed inside the drum, where the liquid from the recirculation device flows through the tank to dissolve and distribute products evenly, preventing bath water from entering and allowing controlled product introduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a product box is used in conventional washing machines, then product introduction is simplified, but product dissolution and distribution effectiveness is poor
Solution Approach 1:
A water-soluble sachet acts as an intermediary carrier between the product box and the laundry. The sachet contains the laundry product and is designed to dissolve in the wash water, releasing the product gradually and uniformly throughout the wash cycle, thereby improving dissolution and distribution effectiveness while maintaining ease of operation.
Solution Approach 2:
The invention changes the physical state and solubility parameters of the product delivery system by using a water-soluble sachet material. This parameter change enables the product to transition from a concentrated solid form in the product box to a dissolved state in the wash water, improving distribution effectiveness.
2Manufacturing precision
If receptacles are placed directly in the linen, then product distribution is improved, but product damage to linen occurs and dissolution is poor
Solution Approach 1:
The water-soluble sachet serves as a protective intermediary between the laundry product and the linen. It contains the product during the wash cycle, preventing direct contact between concentrated product and linen that would cause damage, while still enabling uniform distribution through controlled dissolution.
Solution Approach 2:
The sachet is pre-prepared with the laundry product and designed to dissolve at the appropriate time during the wash cycle. This preliminary preparation ensures that the product is released in a controlled manner, improving distribution while preventing premature contact with linen that would cause damage.
3Loss of time
If product is poured directly onto laundry, then immediate product introduction is achieved, but uniform distribution is poor and concentration issues occur
Solution Approach 1:
The water-soluble sachet acts as a controlled-release intermediary that distributes the laundry product uniformly throughout the wash water over time. This prevents the concentration issues and poor distribution associated with direct pouring, while the sachet's dissolution timing can be controlled to introduce the product at the desired moment in the wash cycle.
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
Improves product dissolution and distribution, preventing damage to laundry, allowing for controlled product introduction at desired times, and enhancing washing performance.
Implementation Method 1
said at least one tank encloses at least one product to be introduced into the bath of the washing tank by dissolution with the liquid from the recirculation device
Implementation Method 2
a liquid recirculation device injecting a liquid from said washing tank in the drum by at least one hole made in at least one flange of said drum

AI summary
The washing machine (1) useful to implement a treatment for waterproof cloth pieces, comprises a housing (2) with wash tank (5) enclosing a rotating drum (6), a recirculation system of injecting a liquid from the wash tank in the drum by a hole spared in a flange of the drum, and a reservoir (13) placed at an inside of the drum and fixed on the flange of the drum by two holes of the recirculation system. The reservoir comprises an opening allowing the flow of liquid from the recirculation system. The washing machine (1) useful to implement a treatment for waterproof cloth pieces, comprises a housing (2) with wash tank (5) enclosing a rotating drum (6), a recirculation system of injecting a liquid from the wash tank in the drum by a hole spared in a flange of the drum, and a reservoir (13) placed at an inside of the drum and fixed on the flange of the drum by two holes of the recirculation system. The reservoir comprises an opening allowing the flow of liquid from the recirculation system, an open exit of the wash water to flow the liquid between the wash tub and a wall of the reservoir, a baffle, an elastic enclosure adapting the flange of the drum, and a treating unit. A position of the reservoir is centered around an axis of rotation drum, and the reservoir covers the hole spared in the flange drum and encloses a liquid, gel or powder formed product to be introduced into the bath wash tub by dissolving with the liquid from the recirculation system. The open exit is arranged in the wall of the reservoir next and close to the flange of the drum. A distance between the wall of the open exit and the flange of the drum is 3 mm. The baffle allows to flow the liquid from the recirculation system between an inlet and an exit opening of the reservoir and prevents the fluid circulating within the drum entering the reservoir. The reservoir partly recovers the holes present in the flange of the drum, and the recirculation system is distributed around an axis of rotation of the drum. The product to be introduced into the wash tub is contained in a water-soluble film, where the product is introduced into the wash tub during a rinse wash classic process.
