Method, device, and processor for detecting dirty blockage in the drainage system of an air conditioner indoor unit

Abstract

The invention belongs to the technical field of air conditioners, and discloses a method, device and processor for detecting dirty blockage of the drainage system of an indoor unit of an air conditioner. Detect the water level at and below the highest safe water level of the drip tray and the pressure at the bottom of the drip tray and the water level of the drip tray at this time, multiple water points can be detected; the processor detects the displacement and / or drainage There is a functional relationship between the value of the flow rate, the height of the water level and the pressure value at the bottom of the water receiving tray, which are collected, read, calculated, fed back, processed, and displayed by the processor to detect the degree of dirty blockage of the drainage system. The invention can effectively remind the user to know the degree of dirty blockage of the drainage system of the indoor unit of the air conditioner, and when the degree of dirty blockage exceeds a certain value, the user is warned to shut down and clean in time.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a method, device and processor for detecting dirty blockage in the drainage system of an indoor unit of an air conditioner. Background technique [0002] At present, the air conditioner indoor unit will inhale and / or absorb dust moving in the air during long-term placement after installation and / or during long-term operation. Among the inhaled and / or adsorbed dust, some dust will be adsorbed in the drainage system The long-term accumulation and adsorption of dust on the outer and inner surfaces of the corresponding parts, coupled with the continuous condensed water produced by air conditioning and refrigeration, will cause the dust in the drainage system to form a sediment-shaped solidified substance under the action of bacteria and fungi, which will flow in the drainage system. During the process, the drainage system of the indoor unit of the air conditioner...

AI Technical Summary

Problems solved by technology

[0005] The indoor unit of the air conditioner is placed for a long time after installation and / or during long-term operation. Dust accumulation and adsorption for a long time, coupled with the continuous condensed water produced by the air conditioner refrigeration, cause the drainage system of the indoor unit of the air conditioner to become dirty and blocked, especially , the impact of the drain is the most serious, which in turn leads to poor drainage of the indoor unit of the air conditioner and water leakage

[0006] Moreover, the existing technology cannot detect the degree of dirty blockage of the indoor unit drainage system of the air conditioner.
