a first connection pipe which sends water stored in the heating water tank to the humidifying water tank; a second connection pipe which is connected such that humidified air generated in the heating water tank and the humidified air generated in the humidified water tank flow; and an exhaust pipe which discharges the humidified air existing inside the humidifying water tank to the outside. ## Claims ### Claim 1 A humidifier comprising: a heating water tank which heats water; a humidifying water tank which is connected to the heating water tank, and generates humidified air by using water supplied from the heating water tank; a first connection pipe which sends water stored in the heating water tank to the humidifying water tank; a second connection pipe which is connected such that humidified air generated in the heating water tank flow into the humidified water tank; and an exhaust pipe which discharges the humidified air existing inside the humidifying water tank to the outside. ### Claim 2 (depends on 1) The humidifier of claim 1, wherein the first connection pipe and the second connection pipe are each arranged to be vertically spaced apart. ### Claim 3 (depends on 1) The humidifier of claim 1, wherein a length of the first connection pipe is formed to be longer than a length of the second connection pipe. ### Claim 4 (depends on 1) The humidifier of claim 1, wherein in the second connection pipe, a first end hole is formed at one end connected to the heating water tank, and a second end hole is formed at the other end connected to the humidifying water tank, wherein the second end hole is disposed in an upper side of the first end hole. ### Claim 5 (depends on 4) The humidifier of claim 4, wherein the first end hole is opened in an up-down direction on an upper surface of the humidifying water tank. ### Claim 6 (depends on 1) The humidifier of claim 1, wherein the exhaust pipe extends downward from an upper surface of the humidifying water tank, wherein a lower hole opened in an up-down direction is formed at a lower end of the exhaust pipe. ### Claim 7 (depends on 6) The humidifier of claim 6, wherein a middle hole opened in a direction facing the second connection pipe is formed in one side of a circumferential surface of the exhaust pipe. ### Claim 8 (depends on 7) The humidifier of claim 7, a groove, which is recessed upwardly in a direction in which the second connection pipe is disposed, is formed at a lower end of peripheral wall of the exhaust pipe. ### Claim 9 (depends on 1) The humidifier of claim 1, wherein a floating valve, which controls water levels of the heating water tank and the humidifying water tank, is disposed in the heating water tank, wherein the first connection pipe is disposed at a location lower than an area where the floating valve moves, wherein the second connection pipe is disposed at a location higher than the area where the floating valve moves. ### Claim 10 (depends on 1) The humidifier of claim 1, wherein an air supply pipe, which supplies air flowing by a blower into the humidifying water tank, is disposed in one side of the humidifying water tank. ### Claim 11 (depends on 10) The humidifier of claim 10, wherein the exhaust pipe is disposed between the air supply pipe and the first connection pipe. ### Claim 12 (depends on 1) The humidifier of claim 1, wherein on a perimeter wall of the exhaust duct, a groove is formed from a lower end of peripheral wall to the upper side, and the groove is disposed in a direction facing each of the second connector and the air supply duct, respectively. ### Claim 13 (depends on 10) The humidifier of claim 10, wherein a supply pipe outlet of the air supply pipe is opened toward a circumferential surface of the exhaust pipe. ### Claim 14 A humidifier comprising: a water tank which stores water; a heating water tank which is disposed in a lower side of the water tank, and forms a heating chamber for heating water supplied from the water tank; a humidifying water tank which is disposed in a lower side of the water tank, and forms a humidifying chamber that generates humidified air by using water supplied from the heating water tank; a first connection pipe which sends water stored in the heating water tank to the humidifying water tank; a second connection pipe which is connected such that humidified air generated in the heating water tank flow into the humidified water tank; and an exhaust pipe which discharges water vapor generated in the heating water tank or the humidified air generated in the humidifying water tank to the lower side of the water tank. ### Claim 15 (depends on 14) The humidifier of claim 14, further comprising a discharge guider spaced apart from an outer circumference of the water tank, wherein an annular discharge passage through which the humidified air discharged from the exhaust pipe flows is formed between the discharge guider and the water tank. ### Claim 16 (depends on 15) The humidifier of claim 15, wherein the discharge guider comprises: an inner guider disposed to be spaced apart from the outer circumference of the water tank; and a lower guide wall which is disposed in a lower side of the inner guider, and forms an inclined surface toward the exhaust pipe. ### Claim 17 A humidifier comprising: a heating water tank which heats water; a humidifying water tank which is connected to the heating water tank, and generates humidified air by using water supplied from the heating water tank; a first connection pipe which sends water stored in the heating water tank to the humidifying water tank; a second connection pipe which extends from each of the heating water tank and the humidifying water tank so that humidified air generated in the heating water tank and the humidified air generated in the humidified water tank flow; and an exhaust pipe which discharges humidified air generated in the heating water tank or the humidified air generated in the humidifying water tank, wherein the exhaust pipe is connected to the second connection pipe. ### Claim 18 (depends on 17) The humidifier of claim 17, wherein a height of the second connection pipe increases as it moves away from each of the humidifying water tank and the heating water tank. ### Claim 19 (depends on 17) The humidifier of claim 17, wherein the second connection pipe is located at an uppermost end in a point of being connected to the exhaust pipe. ### Claim 20 A humidifier comprising: a heating water tank which heats water; a humidifying water tank which is connected to the heating water tank, and generates humidified air by using water supplied from the heating water tank; a first connection pipe which sends water stored in the heating water tank to the humidifying water tank; a second connection pipe which is connected such that humidified air generated in the humidified water tank flow into the heating water tank; and an exhaust pipe which discharges the humidified air existing inside the heating water tank to the outside.
