Laundry Chemistry Dispenser Nozzles for Bellows Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laundry treating appliances face challenges in efficiently dispensing and managing treating chemistries, particularly in providing uniform distribution and cleaning of the bellows, which can lead to buildup and unpleasant odors.
Innovation Solution
A bulk treating chemistry dispenser with at least two spray nozzles, one for the treating chamber and another for the bellows, ensures effective dispensing and cleaning, allowing for improved user access and convenience by integrating the dispenser with the door assembly and utilizing multiple reservoirs for different chemistries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single spray nozzle is used for dispensing treating chemistry, then the device complexity is reduced, but the uniform distribution of treating chemistry and cleaning effectiveness deteriorates
Solution Approach 1:
The spray nozzle is divided into multiple individual nozzles (first spray nozzle, second spray nozzle, third spray nozzle) positioned at different locations and angles. Each nozzle targets specific areas of the bellows, ensuring comprehensive coverage and uniform distribution of treating chemistry without requiring a complex single-nozzle system
2Ease of operation
If the dispenser is integrated with the door assembly, then user access and convenience are improved, but the device complexity increases
Solution Approach 1:
The bulk treating chemistry dispenser is integrated with the door assembly, combining the functions of door operation and chemistry dispensing into a single unit. This allows users to access and operate the dispenser conveniently through the door interface while maintaining a unified structural design
3Reliability
If multiple spray nozzles are added for bellows cleaning, then the cleaning effectiveness is improved, but the loss of substance increases
Solution Approach 1:
Different spray nozzles are positioned to target specific local areas of the bellows (front surface, inner surface, specific zones). This localized spraying approach ensures effective cleaning of critical areas while minimizing overall treating chemistry consumption by avoiding redundant coverage
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 enhances the user experience by allowing single-door access, efficient dispensing of treating chemistries, and automatic cleaning of the bellows, preventing buildup and odors, thus improving the appliance's operational efficiency and convenience.
Implementation Method 1
a bulk treating chemistry dispenser having a dispenser outlet comprising at least two spray nozzles with a first spray nozzle configured to provide a spray toward the treating chamber and a second spray nozzle configured to provide a spray toward the bellows
Data Source
AI summary
A method of operating a laundry treating appliance comprising a treating chamber located within a cabinet of the laundry treating appliance and accessible by an access opening, a bellows extending between the treating chamber and the access opening and a bulk treating chemistry dispenser having a dispenser outlet comprising at least two spray nozzles with a first spray nozzle configured to provide a spray toward the treating chamber and a second spray nozzle configured to provide a spray toward the bellows. The method comprises spraying a first liquid from the first spray nozzle toward the treating chamber and spraying a second liquid from the second spray nozzle toward the bellows.
