Abstract
An automatic extraction device may include a displacement measuring unit for measuring the distance to a container by transmitting a measurement signal and then generating the measurement value which corresponds to the distance to the container; a control unit for outputting a water extraction signal if the measurement value is included within the predetermined target distance range and if the measurement value is not changed during the predetermined reference time; and a water extraction cock for supplying fluid to the container by opening a water extraction valve if the water discharge signal is input.
Claims10
An automatic extraction device comprising:
- a displacement measuring unit configured to transmit a measurement signal to measure a distance to a container and generate a measurement value corresponding to a distance to the container;
- a control unit configured to output a water extraction signal when the generated measurement value corresponds to a distance within a preset target distance range and is not changed for a preset reference period of time;
- a user recognition unit configured to generate a recognition signal upon receiving the water extraction signal;
- and
- a water extraction cock configured to open a water extraction valve to supply fluid to the container,
- wherein the preset target distance range is set by applying a preset error range to a distance from the displacement measuring unit to the water extraction cock,
- wherein, when a preset recognition period of time has lapsed after generating the recognition signal, an opening signal for opening the water extraction valve is input to the water extraction valve of the water extraction cock to start supplying fluid, and
- wherein, after the water extraction signal is output, when the measurement value is increased by more than a preset variation, the control unit outputs a water extraction stop signal to stop the supply of the fluid to the container.
A method for controlling automatic extraction, the method comprising:
- transmitting, by a displacement measuring unit, a measurement signal by a displacement sensor to measure a distance to a container;
- generating a measurement value corresponding to the distance to the container;
- outputting a water extraction signal, by a control unit, when the measurement value corresponds to a distance within a preset target distance range and is not changed for a preset reference period of time;
- and
- opening a water extraction valve to supply fluid to the container when the water extraction signal is output,
- wherein the preset target distance range is set by applying a preset error range to a distance from the displacement measuring unit to the water extraction valve, and
- wherein, after the water extraction signal is output, when the measurement value is increased by more than a preset variation, outputting a water extraction stop signal to stop the supply of the fluid to the container, by the control unit.
An automatic extraction device comprising:
- a displacement measuring unit configured to transmit a measurement signal to measure a distance to a container and generate a measurement value based on the measured distance;
- a valve configured to supply fluid to the container;
- and
- a control unit configured to:
- when the measurement value corresponds to a distance within a preset target distance range and when the measurement value does not change for a preset reference period of time, output a water extraction signal to control the valve to supply a fluid to the container, and
- after the water extraction signal is output, when the measurement value is increased by more than a preset variation, output a water extraction stop signal to stop the supply of the fluid to the container,
- wherein the preset target distance range is set by applying a preset error range to a distance from the displacement measuring unit to the valve.
