Self-cleaning device for condensate drainage pipe of central air conditioner

Abstract

The invention belongs to the technical field of air conditioner drainage, and specifically discloses a self-cleaning device for a condensate drainage pipe of a central air conditioner. The self-cleaning device includes a water source, an air-conditioning condensate main drainage pipe and an automatic washing assembly arranged at the front end of the main drainage pipe, and further includes a solenoid valve arranged on the main drainage pipe. The automatic washing assembly includes a controller, a refrigerant supply pipe temperature sensing probe and a refrigerant return pipe temperature sensing probe, wherein the refrigerant supply pipe temperature sensing probe and the refrigerant return pipe temperature sensing probe are electrically connected with the controller. The solenoid valve is electrically connected with the controller. The self-cleaning device has the advantages of being simple in structure and preventing clogging.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning drainage, and in particular relates to a self-cleaning device for a central air-conditioning condensate drainage pipe. Background technique [0002] At present, the central air conditioner does not have a reliable condensate drainage system, and only relies on the natural discharge of the slope. When the ambient air dust is relatively large, the dust passes through the fan and adheres to the surface cooler. When the air conditioner is in the cooling state, the dust drips with the condensate to the water receiving tray, and then collected into the condensate pipe, due to the reduced flow rate in the main condensate pipe, dust and debris settle at the bottom of the pipe, coupled with the high ambient temperature, they will ferment into gelatinous objects in the pipe, thus blocking the condensation Water leakage caused by water drainage pipes, dripping wet the ceiling, causing the ceiling to...

[0002] At present, the central air conditioner does not have a reliable condensate drainage system, and only relies on the natural discharge of the slope. When the ambient air dust is relatively large, the dust passes through the fan and adheres to the surface cooler. When the air conditioner is in the cooling state, the dust drips with the condensate to the water receiving tray, and then collected into the condensate pipe, due to the reduced flow rate in the main condensate pipe, dust and debris settle at the bottom of the pipe, coupled with the high ambient temperature, they will ferment into gelatinous objects in the pipe, thus blocking the condensation Water leakage caused by water drainage pipes, dripping wet the ceiling, causing the ceiling to become moldy and black, and more seriously, it will cause water damage to the items below, electrical leakage and other secondary disasters
