Abstract
An automatic pipe clean system for massage bath equipment includes a bathtub, a water-filling pipe, a water-draining pipe, a suction pipe, a pump pipe, a pump connected between the suction pipe and the pump pipe, an automatic water-filling pipe, a water-filling valve and a controller. The controller is configured to: in a cleaning stage: turn on the pump to allow the water to pass and clean the suction pipe and the pump pipe; and in a drying stage: turn on the pump to allow the water to drain out from the suction pipe and the pump pipe; and turn off the pump.
