Dishwasher Suction Unit to Reduce Moisture Damage to Furniture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Household dishwashers often release hot, moisture-laden air or steam during the drying cycle, which can damage surrounding furniture and expose users to unpleasant conditions, leading to the need for additional protection measures like steam protection plates or foils.
Innovation Solution
A suction device is integrated into the dishwasher to capture steam and air escaping from the loading opening, redirecting it away from the environment, thereby reducing moisture impact on adjacent furniture and protecting users from rising steam and odors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hot air and steam are vacuumed up and released into the open air during drying, then drying efficiency is improved, but moisture exposure to environment and furniture increases causing damage
Solution Approach 1:
A suction device is introduced as an intermediary component between the washing container and the environment. This device captures steam and moisture-laden air at the loading opening and redirects it through a suction duct away from surrounding furniture, thereby mediating the harmful moisture exposure while preserving drying efficiency
Solution Approach 2:
The harmful factor (steam and moisture-laden air) is extracted from the environment by capturing it at the loading opening with the suction device. The suction device actively removes the moisture-containing air stream before it can contact and damage surrounding furniture
2Object-affected harmful factors
If steam protection plates or foils are installed on furniture to prevent damage, then furniture protection is improved, but device complexity and installation requirements increase
Solution Approach 1:
The harmful moisture-laden air that would normally damage furniture is converted into a controllable air stream. The suction device captures this harmful air and redirects it through a controlled path (suction duct) to a safe discharge location, transforming the harmful exposure into a managed airflow that no longer damages surrounding furniture
Solution Approach 2:
The suction device serves as an intermediary system that eliminates the need for additional protective measures on furniture. By capturing and redirecting the moisture-laden air at its source, the system protects furniture without requiring steam protection plates or foils to be installed
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
The suction device effectively prevents condensation and precipitation on nearby furniture, keeping the environment dry and reducing exposure to hot steam and odors, eliminating the need for additional protection measures.
Implementation Method 1
at least one suction device (28) is provided for extracting steam and/or air escaping from the loading opening (27)
