Drain cleaner apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air-conditioning systems face challenges in maintaining clean condensate drain lines without manual intervention, leading to potential clogging and system shutdowns due to the buildup of substances like mold, algae, and bacteria.
Innovation Solution
A drain cleaner apparatus that automatically dispenses a cleaning composition into the condensate drain line using a dispenser device actuated by a controller, which includes a timer and network communication interface to manage the dispensation and monitor the cleaning composition level, ensuring regular cleaning without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cleaning intervention is used, then the condensate drain line can be cleaned, but the system requires human intervention and may still experience clogging between cleanings
Solution Approach 1:
The system uses an automatic dispenser device that dispenses cleaning composition into the condensate drain line without human intervention. The dispenser is actuated by a controller on a scheduled basis, allowing the system to clean itself automatically, thereby improving reliability while eliminating the need for manual operation.
Solution Approach 2:
The controller is configured to actuate the dispenser device before clogging occurs, based on predetermined time intervals or operational cycles. This preliminary cleaning action prevents buildup of mold, algae, and bacteria, maintaining drain line cleanliness proactively rather than reactively.
2Ease of operation
If automatic dispenser device is implemented, then manual intervention is eliminated, but the device complexity increases
Solution Approach 1:
The controller serves multiple functions: it tracks operational cycles, determines when cleaning is needed based on predetermined criteria, actuates the dispenser device, and monitors cleaning composition levels. By consolidating these functions into a single controller, the system achieves automatic operation while minimizing the number of separate components, thus managing complexity.
Solution Approach 2:
The dispenser device is integrated with the air handler unit, and the controller combines scheduling, monitoring, and actuation functions. This merging of components and functions reduces the overall system complexity compared to having separate standalone automatic cleaning systems.
3Reliability
If regular cleaning is performed, then clogging is prevented, but cleaning composition is consumed
Solution Approach 1:
The controller monitors the level of cleaning composition in the reservoir and can detect when it needs replenishment. This feedback mechanism allows the system to maintain reliable automatic cleaning operation while tracking consumption, enabling timely refilling before the composition is depleted.
Solution Approach 2:
The dispenser device is configured to dispense predetermined amounts of cleaning composition at scheduled intervals, which may be optimized to use the minimum effective amount needed for prevention rather than continuous or excessive application. This approach prevents clogging while managing consumption rates.

AI summary
An apparatus configured to dispense a cleaner composition includes an apparatus outlet in fluid communication with an exterior of the apparatus, a dispenser device configured to be operated to selectively dispense an amount of the cleaning composition through the apparatus outlet, and a controller configured to operate the dispenser device to cause the amount of the cleaning composition to be dispensed through the apparatus outlet without manual intervention. The apparatus is configured to be electrically connected with a float switch concurrently with dispensing the cleaning composition, and the apparatus is configured to cause at least a portion of an air conditioning system to shut down in response to receiving a signal generated by the float switch.
