a water supply pipe which is disposed in the lower side of the water tank, and supplies the water supplied from the water tank to the humidifying water tank; and an inner guider disposed spaced apart from an outer circumference of the water tank, wherein a discharge passage through which the humidified air generated in the humidifying water tank flows is formed between the water tank and the inner guide, wherein the inner guider comprises a bottom wall which has a first bottom hole, and a second bottom hole. ## Claims ### Claim 1 A humidifier, comprising: a water tank for storing water; a humidifying water tank which is disposed in a lower side of the water tank, and generates humidified air by using water supplied to the water tank; a water supply pipe which is disposed in the lower side of the water tank, and supplies the water supplied from the water tank to the humidifying water tank; and an inner guider disposed spaced apart from an outer circumference of the water tank, wherein a discharge passage through which the humidified air generated in the humidifying water tank flows is formed between the water tank and the inner guide, wherein the inner guider comprises a bottom wall which has a first bottom hole that is disposed in the lower side of the water tank and communicates the humidifying water tank and the discharge passage, and a second bottom hole in which at least a portion of the water tank and the water supply pipe is disposed, wherein the bottom wall forms an inclined surface so that the first bottom hole is located lower than the second bottom hole. ### Claim 2 (depends on 1) The humidifier of claim 1, wherein the bottom wall comprises a first pipe protruding downward from an outer circumference of the first bottom hole, and a second pipe protruding upward from an outer circumference of the second bottom hole. ### Claim 3 (depends on 2) The humidifier of claim 2, wherein an exhaust pipe is formed in the humidifying water tank to send the humidified air generated in the humidifying water tank to the discharge passage, wherein the first pipe is disposed to be inserted into the exhaust pipe. ### Claim 4 (depends on 1) The humidifier of claim 1, wherein an area of the first bottom hole is formed to be smaller than an area of a lower surface of the water tank. ### Claim 5 (depends on 1) The humidifier of claim 1, wherein the second bottom hole is disposed in a center of the bottom wall, and the first bottom hole is disposed to be radially spaced from the second bottom hole. ### Claim 6 (depends on 1) The humidifier of claim 1, wherein in the bottom wall, an inclination angle formed between a surface extending from the first bottom hole in a direction in which the second bottom hole is disposed and a virtual horizontal line is formed to be smaller than an inclination angle formed between a surface extending from the first bottom hole in an opposite direction in which the second bottom hole is disposed and a virtual horizontal line. ### Claim 7 (depends on 1) The humidifier of claim 1, wherein the first bottom hole and the second bottom hole are open toward a lower surface of the water tank. ### Claim 8 (depends on 1) The humidifier of claim 1, wherein the water tank comprises an inner water tank which stores water, and an outer water tank which is disposed around an outer circumference of the inner water tank and fixes a disposition of the inner water tank, wherein the inner water tank penetrates the outer water tank and is connected to the water supply pipe. ### Claim 9 (depends on 8) The humidifier of claim 8, wherein the outer water tank comprises a barrier protruding outward in a radial direction at a lower end of the outer water tank. ### Claim 10 (depends on 9) The humidifier of claim 9, wherein a length of the barrier protruding in the radial direction from the lower end of the outer water tank is formed to be different depending on a distance spaced apart from the first bottom hole. ### Claim 11 (depends on 8) The humidifier of claim 8, wherein the outer water tank comprises a plurality of fixing protrusions protruding downward to fix the outer water tank to the inner guider. ### Claim 12 (depends on 11) The humidifier of claim 11, wherein a plurality of fixing protrusion grooves into which the plurality of fixing protrusions are inserted are formed in the bottom wall. ### Claim 13 (depends on 10) The humidifier of claim 10, wherein a through-hole is formed in a lower surface of the outer water tank, wherein a lower portion of the inner water tank is disposed to penetrate the through-hole. ### Claim 14 (depends on 13) The humidifier of claim 13, wherein the through-hole is disposed in an upper side of the second bottom hole, wherein a second pipe protruding upward along an outer circumference of the second bottom hole is disposed on the bottom wall, wherein a diameter of an inner circumferential surface of the through-hole is formed larger than a diameter of an outer circumferential surface of the second pipe. ### Claim 15 (depends on 14) The humidifier of claim 14, wherein an upper end of the second pipe is disposed in contact with a lower side of the inner water tank. ### Claim 16 (depends on 14) The humidifier of claim 14, wherein the inner water tank comprises: an inner housing which forms a space for storing water therein and has a tank hole formed in a lower portion; a cap disposed to open and close the tank hole; and a tank connector extending downward around the tank hole, wherein the tank connector is disposed to be inserted into an interior of the second pipe. ### Claim 17 A humidifier, comprising: a water tank for storing water; a heating water tank which is disposed in a lower side of the water tank, and heats water received from the water tank; a humidifying water tank which is disposed in a lower side of the water tank, and generates humidified air by receiving the water heated in the heating water tank; and an inner guider disposed spaced apart from an outer circumference of the water tank, wherein a discharge passage through which the humidified air generated in the humidifying water tank flows is formed between the water tank and the inner guide, wherein the inner guider comprises a bottom wall which has a first bottom hole that is disposed in the lower side of the water tank and communicates the humidifying water tank with the discharge passage, wherein the humidifying water tank comprises an exhaust pipe extending downward from an upper portion of the humidifying water tank to communicate an interior of the humidifying water tank with the discharge passage, wherein the exhaust pipe is disposed in a lower side of the first bottom hole. ### Claim 18 (depends on 17) The humidifier of claim 17, further comprising: a first connection pipe which supplies the water heated in the heating water tank to the humidifying water tank; and a second connection pipe which is disposed to be spaced upward from the first connection pipe and connects the heating water tank and the humidifying water tank, wherein the second connection pipe is opened toward a circumferential surface of the exhaust pipe. ### Claim 19 (depends on 18) The humidifier of claim 18, wherein the exhaust pipe protrudes lower than the second connection pipe. ### Claim 20 (depends on 18) The humidifier of claim 18, wherein a middle hole opened toward the second connection pipe is formed in the circumferential surface of the exhaust pipe.
