Humidifier

A humidifier, comprising:

• a heating water tank which forms a heating chamber for heating water therein;
• a humidifying water tank which is disposed in one side of the heating water tank, is connected to the heating water tank, and generates humidified air by using water supplied from the heating water tank;
• a connection pipe which sends water stored in the heating water tank to the humidifying water tank;
• an air flow pipe which is connected to allow a humidified air generated in the heating water tank and a humidified air generated in the humidifying water tank to flow;
• and
• a floating valve which is disposed to be movable in an up-down direction in the heating water tank, and controls a water level of the heating water tank and a water level of the humidifying water tank, wherein the floating valve is disposed to be movable in an up-down direction between the connection pipe and the air flow pipe.

A humidifier, comprising:

• a water tank for storing water;
• a heating water tank which is disposed below the water tank, and heats water supplied from the water tank;
• a humidifying water tank which is disposed below the water tank, and generates humidified air by using water supplied from the heating water tank;
• a connection pipe which connects the heating water tank and the humidifying water tank so that water stored in the heating water tank flows into the humidifying water tank;
• a floating valve which is disposed in the heating water tank, and controls a water level of the heating water tank;
• and
• an exhaust pipe which discharges the humidified air existing in the humidifying water tank to the outside, wherein a lower end portion of the exhaust pipe is located inside the humidifying water tank, wherein the floating valve maintains a water level of the humidifying water tank at a certain gap below the lower end portion of the exhaust pipe located inside the humidifying water tank.
