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.
Claims20
An automatic pipe clean system for massage bath equipment, comprising:
- a bathtub which includes a water-draining port, a suction port, a water-jet port, and a water level sensor arranged in the bathtub;
- a water-filling pipe which supplies water to the bathtub;
- a water-draining pipe connected to the water-draining port;
- a water-draining valve installed on the water-draining pipe;
- a suction pipe connected between a pump and the suction port;
- a pump pipe connected between the pump and the water-jet port;
- a blower pipe connected between a blower and an air-jet port of the bathtub;
- an automatic water-filling pipe connected between the water-filling pipe and a water-filling port of the bathtub, and automatically supplies water for cleaning;
- a water-filling valve arranged in the automatic water-filling pipe;
- and
- a controller electrically connected to the pump, the blower, the water-draining valve, the water level sensor, and the water-filling valve;
- the controller being configured to:
- in a cleaning function:
- turn on the pump to allow the water to pass and clean the suction pipe and the pump pipe;
- turn on and control the blower to perform an intermittent operation to clean the blower pipe, wherein the intermittent operation is an alternate operation of turning on and turning off the blower and/or the pump;
- in a water-draining function:
- detect the water level of the bathtub by the water level sensor;
- and
- determine:
- if the bathtub has water, then open the water-draining valve to allow the water to drain out from the bathtub through the water-draining pipe;
- if the bathtub has no water, then close the water-draining valve to stop the water from draining out from the bathtub through the water-draining pipe;
- in a drying function:
- turn on the pump to allow the water to drain out from the suction pipe and the pump pipe;
- turn on the blower to blow dry the blower pipe;
- and
- turn off the blower and the pump.
