Abstract
A beverage maker may include a water tank storing water; a water supply pump provided below the water tank to receive water from the water tank, a water supply channel connected to the water supply pump to guide water discharged from the water supply pump, an air removing channel connected to the water supply channel, an air removing valve or cap connected to the air removing channel, and a controller maintaining the water supply pump in an off state when the air removing valve is opened.
Claims20
A beverage maker comprising:
- a tank that stores liquid;
- a pump provided below the tank to pump liquid from the tank;
- a liquid channel connected to the pump and guiding liquid discharged from the pump;
- a gas channel connected to the liquid channel and through which gas from the pump flows;
- a heater that heats liquid in the liquid channel;
- an air pump that injects air into the heated liquid;
- a valve connected to the gas channel to discharge gas from the gas channel;
- and
- a controller maintaining the pump in an off state when the valve is opened,
- wherein the pump is located below a lower end of the tank,
- wherein the valve is located above the pump, the heater, and the air pump, and the valve is located above the lower end of the tank,
- wherein, while the pump is turned off, the controller opens the valve such that liquid from the tank flows down to the pump from the tank, and gas flows from the pump through the valve due to liquid from the tank flowing to the pump,
- wherein, when the valve is opened for a predetermined period of time or more, the controller closes the valve, and
- wherein the controller turns on the pump after the valve is closed.

A beverage maker comprising:
- a first tank that stores liquid;
- a pump provided below the first tank to pump liquid from the first tank;
- a liquid channel connected to the pump and guiding liquid discharged from the pump;
- a gas channel connected to the liquid channel through which gas from the pump flows;
- a valve connected to the gas channel to discharge gas from the gas channel;
- a second tank that receives liquid from the liquid channel to form the beverage;
- a temperature module that adjusts a temperature of liquid in the second tank, the temperature module including a compressor provided below the first tank;
- and
- a controller configured to manage the pump and the valve,
- wherein the pump is located below a lower end of the first tank,
- wherein the valve is located above the pump, the compressor, and the lower end of the first tank,
- wherein the valve is opened while the pump is turned off such that liquid from the tank flows to the pump due to hydraulic pressure, and gas flows from the pump to the valve due to liquid from the tank flowing to the pump,
- wherein after the valve is opened for at least a predetermined period of time, the controller closes the valve and turns on the pump.

A beverage maker comprising:
- a first tower including:
- a tank that stores liquid;
- and
- a pump provided below the tank to receive liquid from the tank;
- a liquid channel that receives liquid discharged from the pump;
- a gas channel connected to the liquid channel to receive gas in the liquid channel;
- a valve that is connected to the gas channel and discharges gas when opened;
- a second tower including a fermenter;
- and
- a material supplier provided between the first tower and the second tower, the material supplier supplying an ingredient to liquid in the liquid channel liquid, and the fermenter receiving liquid containing the ingredient,
- wherein the valve is positioned between the first tower and the second tower, below the material supplier, and higher than a lower end of the tank,
- wherein, before the pump is turned on, the valve opens such that liquid from the tank flows to the pump without operation of the pump, and gas flows to the valve from the pump due to liquid from the tank flowing to the pump, and
- wherein valve closes after being opened for at least a predetermined period of time, and the pump turns on after the valve closes.
