Dishwasher Auto-Open Door Control Using External Air Quality Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dishwashers with auto-open door functions during drying face contamination issues due to foreign substances penetrating from poor indoor air quality, which existing control methods fail to address effectively.
Innovation Solution
A control system integrating an air quality detection device and a mobile device to monitor indoor air quality, allowing users to activate or deactivate the auto-open door function based on set air quality ranges, preventing foreign substances from entering the dishwasher.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the door is opened during drying process, then drying efficiency is improved, but foreign substances may penetrate into the dishwasher and contaminate dishes
Solution Approach 1:
The control device receives air quality information from the detection device and automatically adjusts door opening operations based on real-time air quality feedback. When air quality is poor (high contamination level), the control device limits or prevents door opening during drying, thereby preventing contamination while maintaining drying function. This closed-loop feedback mechanism resolves the contradiction by dynamically adapting door operation to environmental conditions.
Solution Approach 2:
The system uses an air quality detection device (such as an air purifier or air conditioner with sensing capability) already present in the kitchen environment to provide contamination level information. This leverages existing infrastructure to make informed decisions about door operation, enabling the dishwasher to autonomously protect itself from contamination based on environmental conditions.
2Object-affected harmful factors
If air quality detection device is integrated into dishwasher, then contamination prevention is improved, but device complexity increases
Solution Approach 1:
The system utilizes air quality detection devices (air purifiers, air conditioners, or standalone air quality monitors) that are commonly present in kitchen environments for multiple purposes. These devices not only perform their primary air treatment or monitoring function but also provide air quality data to the dishwasher's control device, enabling contamination prevention. This multi-functional approach avoids adding dedicated detection hardware to the dishwasher.
Solution Approach 2:
The control device acts as an intermediary that receives air quality information from external detection devices and translates it into appropriate door operation commands. This mediator approach allows the dishwasher to benefit from external sensing capabilities without directly integrating complex detection hardware, thereby maintaining system simplicity while achieving contamination prevention.

AI summary
A method of controlling a dishwasher according to an embodiment may include linking a dishwasher and an air quality detection device, which is provided outside the dishwasher, with each other, receiving whether to activate an auto open door (AOD) function of the dishwasher, determining whether or not quality of indoor air input from the air quality detection device is within a set range, when the quality of the indoor air deviates from the set range, recommending a user to deactivate AOD of the dishwasher, maintaining or deactivating the AOD function of the dishwasher based on a command input from the user, and washing a washing target.
