an inner wall which is disposed inside the outer wall, and receives water from a water tank and sends to an inner space of the outer wall; and a floating valve which is movable in an up-down direction within the inner wall. ## Claims ### Claim 1 A humidifier comprising: an outer wall which forms a space where water is stored; a heater which is disposed in a lower side of the outer wall, and heats water stored inside the outer wall; an inner wall which is disposed inside the outer wall, and receives water from upper side and sends to an inner space of the outer wall; and a floating valve which is movable in an up-down direction within the inner wall. ### Claim 2 (depends on 1) The humidifier of claim 1, wherein a center of the inner wall is spaced apart from a center of the outer wall. ### Claim 3 (depends on 1) The humidifier of claim 1, wherein a central hole, which penetrates the floating valve in the up-down direction, is formed in a center of the floating valve, and a communication hole, which communicates an interior of the inner wall with an interior of the outer wall, is formed in the inner wall, wherein the communication hole is disposed in a lower side of the central hole. ### Claim 4 (depends on 3) The humidifier of claim 3, wherein a size of the communication hole is the same as or larger than a size of the central hole. ### Claim 5 (depends on 1) The humidifier of claim 1, further comprising a plurality of separation ribs that protrude from a circumferential surface of the inner wall to the inside of the inner wall, and are disposed in contact with the floating valve, wherein the plurality of separation ribs are disposed to be spaced apart in a circumferential direction in the inside of the inner wall. ### Claim 6 (depends on 5) The humidifier of claim 5, wherein a guide groove corresponding to the separation rib is formed in an outer circumference of the floating valve. ### Claim 7 (depends on 1) The humidifier of claim 1, further comprising a water supply tank which is disposed in an upper side of the inner wall and forms a water supply hole to supply water to the inner wall. ### Claim 8 (depends on 7) The humidifier of claim 7, wherein the floating valve comprises: a valve body forming a central hole therein; and a valve stopper which is disposed in the central hole and opens and closes the water supply hole. ### Claim 9 (depends on 8) The humidifier of claim 8, wherein a guide protrusion protruding downward is disposed in a lower surface of the water supply tank so as to guide an up-down movement of the valve stopper. ### Claim 10 (depends on 9) The humidifier of claim 9, wherein at least a portion of the guide protrusion is located in the central hole. ### Claim 11 (depends on 10) The humidifier of claim 10, wherein a pair of guide protrusions in which semicircular structures are spaced apart from each other are disposed in the lower surface of the water supply tank, wherein the pair of guide protrusions are spaced apart from each other to form a gap. ### Claim 12 (depends on 11) The humidifier of claim 11, wherein the water supply hole is disposed between a pair of guide protrusions. ### Claim 13 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 heats water stored therein; and a water supply tank which supplies the water stored in the water tank to the heating water tank, wherein the heating water tank comprises: an outer wall which forms a space where water is stored; a heater which is disposed in a lower side of the outer wall, and heats water stored inside the outer wall; an inner wall which is disposed inside the outer wall, and disposed in a lower side of the water supply tank to send water supplied from the water supply tank to the inside of the outer wall; and a floating valve which is movable in an up-down direction within the inner wall. ### Claim 14 (depends on 13) The humidifier of claim 13, wherein the inner wall is disposed to be spaced upward from the heater, wherein a communication hole is formed in the inner wall to communicate between the inside of the inner wall and the inside of the outer wall, and wherein a central hole opened in an up-down direction from an upper side of the communication hole is formed in the floating valve. ### Claim 15 (depends on 14) The humidifier of claim 14, wherein a water supply hole is formed in the water supply tank to supply water to the inner wall, wherein a valve stopper which opens and closes the water supply hole is disposed inside the central hole of the floating valve. ### Claim 16 (depends on 13) The humidifier of claim 13, wherein a lower end of the water supply tank is disposed lower than an upper end of the inner wall. ### Claim 17 A humidifier comprising: a heating water tank wall which forms a space where water is stored therein; a heater which is disposed in a lower side of the heating water tank wall, and heats water stored inside the heating water tank wall; a floating valve which is disposed to be movable in an up-down direction inside the heating water tank wall, and adjusts a level of water stored inside the heating water tank wall; and a connector which has a water supply tank which is disposed in an upper side of the heating water tank wall and supplies water to the inside of the heating water tank wall, and an air flow pipe which discharges a humidified air generated inside the heating water tank wall, wherein the heating water tank wall comprises: an outer wall which forms a space where water is stored; and an inner wall which is disposed inside the outer wall, and receives water from the water supply tank and sends the received water to an inner space of the outer wall, wherein the floating valve is disposed inside the inner wall. ### Claim 18 (depends on 17) The humidifier of claim 17, wherein the connector further comprises a plate disposed in an upper side of the humidifying water tank wall, wherein the water supply tank has a shape concave downward from the plate, wherein the air flow pipe forms a flow path through which air flows upward from the plate. ### Claim 19 (depends on 18) The humidifier of claim 18, wherein in the air flow pipe, a flow pipe inlet opened in an up-down direction is formed so that air inside the outer wall flows to the inside of the air flow pipe, wherein the flow pipe inlet is disposed in an upper side of an area excluding an area where the inner wall is disposed. ### Claim 20 (depends on 18) The humidifier of claim 18, wherein the connector comprises a lower peripheral wall that protrudes downward from the plate so as to face an inner circumferential surface of the outer wall, wherein a sealer is disposed between the lower peripheral wall and the heating water tank.
