Fixed Dishwasher Nozzle Assembly for Clog-Resistant Joint Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dish washing machines with fixed nozzle assemblies in linear jet structures face challenges in minimizing the introduction of foreign substances due to the design of the nozzle assembly, leading to potential clogging and reduced efficiency.
Innovation Solution
The dish washing machine incorporates a guide rib and nozzle support rib in the nozzle assembly to prevent foreign substances from entering the internal space, with a specific configuration that includes inclined surfaces and a predetermined interval to ensure effective washing water flow and discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the nozzle assembly uses a simple combined structure of nozzle front cover and nozzle body, then the device complexity is reduced and ease of manufacture is improved, but foreign substances can be introduced into the combining portion leading to clogging and reduced reliability
Solution Approach 1:
The guide rib is provided in advance on the nozzle front cover to prevent foreign substances from entering the combining portion between the nozzle front cover and nozzle body. This preliminary protective structure is built into the design before assembly, proactively preventing clogging issues rather than addressing them after they occur.
Solution Approach 2:
The guide rib acts as an intermediary protective element between the external environment and the internal combining portion of the nozzle assembly. It mediates by guiding washing water flow while blocking foreign substances, allowing water to pass through while preventing contaminants from entering the critical combining area.
2Reliability
If the nozzle front cover is combined closely with the nozzle body to prevent foreign substance entry, then reliability is improved, but washing water flow may be restricted and productivity is reduced
Solution Approach 1:
The guide rib provides localized protection at the combining portion where foreign substance entry is most likely to occur. Rather than requiring complete sealing or tight combination of the entire nozzle front cover and nozzle body, the protective function is concentrated locally at the critical combining area, allowing water flow to remain unrestricted in other areas.
Solution Approach 2:
The guide rib structure is pre-configured on the nozzle front cover to create a protective barrier before assembly. This preliminary structure prevents foreign substances from reaching the combining portion while maintaining adequate spacing for water flow, eliminating the need for tight combinations that would restrict productivity.
3Reliability
If the nozzle assembly is designed with foreign substance prevention features like guide ribs, then reliability is improved, but device complexity increases and ease of manufacture deteriorates
Solution Approach 1:
The guide rib on the nozzle front cover serves multiple functions simultaneously: it guides the flow of washing water, prevents foreign substances from entering the combining portion, and maintains structural integrity. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while still improving reliability.

AI summary
There is provided a dish washing machine, including a main body; a washing tank provided inside the main body; and a fixed nozzle assembly fixed in one side of the washing tank and configured to jet washing water, wherein the fixed nozzle assembly includes, a nozzle body having a jet nozzle configured to jet washing water; and a nozzle front cover combined with a front surface of the nozzle body, and wherein the nozzle front cover and/or the nozzle body include corresponding ribs to cover a combining portion between the nozzle front cover and the nozzle body to minimize a foreign substance from being introduced into the combining portion of the nozzle front cover and the nozzle body. According to such a configuration, it is possible to minimize contaminants from accumulating in the fixed nozzle assembly.
