Centrifugal Juicer Pulp Bin Structure for Cleaner Residue Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centrifugal juicers face difficulties in conveniently and efficiently collecting and removing pulp residues, which tend to adhere to internal surfaces due to their formation and the formation of vortices during operation, leading to inefficient residue collection and frequent cleaning.
Innovation Solution
A centrifugal juicer design featuring a removable container with a letterbox-like aperture and filler aperture, positioned to encourage pulp collection, and a sliding mechanism for easy installation and removal, along with a safety interlock to ensure proper operation only when the container is in place, effectively guiding pulp into the container and minimizing re-circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a rigid container is used to collect pulp, then the pulp-handling capacity is limited and requires frequent removal/emptying, but using a collapsible container increases capacity and reduces frequency of removal
Solution Approach 1:
The container is designed to be collapsible rather than rigid, allowing it to dynamically change volume as it fills with pulp. This dynamic structure increases the effective pulp-handling capacity while maintaining ease of removal and emptying, as the container can be easily collapsed for storage and re-expanded for use.
2Productivity
If pulp residues are allowed to collect in the working zone, then the collection efficiency is poor and internal surfaces become coated, but implementing a collection system increases device complexity
Solution Approach 1:
The collection system is segmented into a removable container that can be easily detached from the main juicing assembly. This segmentation allows the collection function to be separated from the juicing function, reducing the complexity of the integrated system while improving pulp collection efficiency through dedicated collection space.
Solution Approach 2:
The pulp collection container is designed to be completely removable from the juicer body, extracting the collection function as a separate component. This extraction simplifies the overall device by allowing the collection system to be independently managed, cleaned, and replaced without affecting the main juicing mechanism.
3Ease of operation
If the container is made removable for easy cleaning, then the installation and removal convenience is improved, but the risk of improper installation affecting operation increases
Solution Approach 1:
A safety interlock mechanism provides feedback to indicate whether the container is properly installed before allowing the juicer to operate. This feedback system maintains reliability by preventing operation with improper installation while preserving the ease of removable installation and removal for cleaning purposes.
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 design allows for the efficient collection of over 90% of pulp residues in the removable container, reducing the need for frequent cleaning and maintaining the juicer's internal surfaces free from unwanted pulp, enhancing user convenience and operational efficiency.
Implementation Method 1
The cutter plate, and usually also the filter member, are spun sufficiently rapidly to separate the juice from pulp residues, comprising mainly fibrous bulk matter; the juice passing through the apertures in the frusto-conical wall for collection and dispensing and the pulp residues being blocked by the filter member and generally thrown upwardly and outwardly therefrom.

AI summary
The invention provides a centrifugal juicer with a removable container, or bin, for collection of the unwanted pulp generated by the juicing process. A macerator is located in a working zone of the juicer, and the pulp is thrown upwardly and outwardly away from the macerator, and exits through a letterbox-like aperture which aligns with a filler aperture in the bin when the bin is placed correctly for operation of the juicer. The bin is slidably movable towards and away from the juicer and is open-topped; the bin being covered during operation by a roof member which extends outwardly from the juicer. The bin is provided with an upper bridging member, above the filler aperture; the bridging member having a surface adapted to slide in contact with, or closely adjacent, the underside of the roof, thereby to wipe pulp deposits from the roof when the bin is slid away from the juicer for removal.
