Dishwasher providing notification for replacing filter and method of providing a notification for replacing a filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwashers do not provide intuitive notifications for replacing air filters based on time of use or number of uses, making it difficult for users to know when the filter needs replacement.
Innovation Solution
A dishwasher system that includes a notification mechanism to alert users when the air filter needs replacement, based on accumulated operation time or number of uses, and optionally communicates this information to a mobile device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter state is merely displayed as in related art, then the device complexity is reduced, but the user cannot intuitively know when the filter needs replacement
Solution Approach 1:
The system implements feedback by monitoring filter usage through operation time accumulation and usage count tracking, then providing notifications when replacement thresholds are reached. This closes the information loop between filter degradation and user awareness, solving the problem of users not intuitively knowing when replacement is needed.
Solution Approach 2:
The system performs preliminary actions by tracking and accumulating filter usage data before the filter actually degrades to a non-functional state. Notifications are issued in advance based on predetermined time or usage thresholds, allowing users to replace filters proactively before performance deterioration occurs.
2Loss of time
If filter replacement notifications are not transmitted to mobile terminals as in related art, then the device complexity is reduced, but the user cannot receive timely notifications
Solution Approach 1:
The system uses a communication device as an intermediary to transmit filter replacement notifications from the dishwasher to the user's mobile terminal. This mediator enables timely remote notification without requiring complex direct connection mechanisms, bridging the gap between the appliance and the user effectively.
Solution Approach 2:
The communication system provides feedback by delivering real-time notifications to users' mobile devices when filter replacement is needed. This extends the feedback mechanism beyond the appliance display to the user's personal device, ensuring timely awareness and action.
3Measurement precision
If the dishwasher does not track operation time and usage count, then the device complexity is reduced, but the filter replacement timing cannot be determined accurately
Solution Approach 1:
The system performs preliminary tracking of operation time and usage count throughout the filter's service life. By continuously accumulating this data before replacement is needed, the system establishes an accurate baseline for determining when the filter has reached its effective lifespan, enabling precise replacement timing decisions.
Solution Approach 2:
The monitoring system provides continuous feedback on filter usage through time tracking and usage counting. This data feedback mechanism enables the system to accurately determine filter replacement timing by comparing accumulated usage against predetermined thresholds, ensuring replacements occur at optimal intervals.

AI summary
The present disclosure relates to a dishwasher and a method for providing a notification for replacing a filter. To this end, the dishwasher according to the present disclosure can continue to accumulate operation time of an air blowing fan of the dishwasher, and when total accumulative operation time is predetermined time or greater, can output a notification for replacing a filter through a display or a speaker, making it possible to determine the timing of the replacement of the filter accurately.
