Solution Overview
Problem
Existing air-conditioning systems face challenges in efficiently managing water accumulation, particularly during rainy weather, which can lead to prolonged operation of the water pump, reduced service life, and degraded user experience due to mixing of rainwater with impurities.
Innovation Solution
A drainage control method and apparatus for air-conditioning devices that utilize water level switches to control the operation of drainage and spray pumps. The method involves transferring water from an outdoor tank to an indoor tank during non-rainy conditions and discharging it during rainy weather, thereby reducing pump operation time and extending its lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the water pump operates continuously to discharge accumulated water, then the water discharge function is ensured, but the service life of the water pump is reduced and user experience is degraded
Solution Approach 1:
The system performs preliminary action by storing rainwater in the outdoor water storage tank before it mixes with impurities. The water level switches detect rainwater accumulation in advance, triggering the drainage pump to transfer water to the indoor tank before contamination occurs, thus preventing the need for prolonged pump operation later
Solution Approach 2:
The indoor water storage tank serves as an intermediary between the outdoor environment and the water pump. By transferring rainwater to this intermediate storage location, the system isolates the pump from direct exposure to rainwater and impurities, reducing wear and extending service life
2Productivity
If the water pump operates for a long time during rainy weather, then rainwater is discharged, but impurities mix with rainwater causing damage to the water pump
Solution Approach 1:
The system segments the water discharge function into two independent pathways: (1) The drainage pump transfers rainwater from the outdoor tank to the indoor tank, and (2) The spray pump discharges water from the indoor tank to the outdoor environment. This segmentation allows rainwater to be separated from impurities at different stages, preventing contamination damage to the pumps
3Duration of action of moving object
If the drainage pump transfers water from outdoor tank to indoor tank, then pump operation time is reduced, but system complexity increases
Solution Approach 1:
The indoor water storage tank serves multiple functions: (1) Receiving rainwater from the outdoor tank via the drainage pump, (2) Storing water for later discharge by the spray pump, and (3) Acting as a buffer to reduce the operational frequency of both pumps. This multi-functionality justifies the added system complexity by providing significant operational benefits

AI summary
An air conditioner, a drainage control method and apparatus therefor, and a computer-readable storage medium are provided. An outdoor water storage tank of the air conditioner has a first outdoor water level switch and a second outdoor water level switch. An indoor water storage tank of the air conditioner has a first indoor water level switch. The drainage control method includes controlling, in response to the first indoor water level switch not being triggered and the first outdoor water level switch or the second outdoor water level switch being triggered, a drainage pump to operate, to discharge water in the outdoor water storage tank into the indoor water storage tank for water storage. The method further includes determining that rainy weather occurs, and controlling a spray pump to operate to discharge water in the indoor water storage tank to an outdoor environment.
