         4 . The humidifier of  claim 3 , wherein the vibration device is disposed on a bottom surface of the water humidifier tank, and a return groove that forms a space at a side of the vibration device is formed at the water humidifier tank, and wherein the second connection tube is connected to the water humidifier tank at a side at which the return groove is formed. 
     
     
         5 . The humidifier of  claim 3 , wherein the water humidifier tank comprises an inflow hole formed in a region connected with the first connection tube, and a return discharge hole formed in a region connected with the second connection tube, and wherein the return discharge hole is formed at a position lower than the inflow hole. 
     
     
         6 . The humidifier of  claim 3 , wherein the second connection tube includes a pump inflow tube that connects the humidifying device and the pump, and a pump discharge tube that connects the heating device and the pump, and wherein the pump is disposed higher than a region in which the second connection tube is connected to the humidifying device and the heating device. 
     
     
         7 . The humidifier of  claim 1 , comprising a drain tube that is disposed on a side of the heating device and drains water in the heating device to the outside. 
     
     
         8 . The humidifier of  claim 7 , wherein the heating device includes:
 a water heater tank that forms a space in which water is stored; and   a heater disposed under the water heater tank and that heats water stored in the water heater tank, and wherein the drain tube is disposed on a side of the water heater tank at which the heater is disposed.   
     
     
         9 . The humidifier of  claim 8 , wherein the heater is spaced apart from an inner circumferential surface of the water heater tank, and a drain hole connected with the drain tube is formed at the water heater tank on the side at which the heater is disposed. 
     
     
         10 . The humidifier of  claim 1 , comprising:
 a blower fan that generates airflow outside of the heating device and the humidifying device; and   an air guide cover that supplies air flowing around the humidifying device into the humidifying device.   
     
     
         11 . The humidifier of  claim 10 , wherein the humidifying device includes a lower extension wall disposed such that air flowing into the humidifying device through the air guide cover flows under the lower extension wall. 
     
     
         12 . The humidifier of  claim 11 , wherein the humidifying device comprises an exhaust hole formed such that humidified air produced in the humidifying device is discharged out of the humidifying device, and an air supply hole formed such that air flowing through the air guide cover flows into the humidifying device, and wherein the lower extension wall is disposed between the exhaust hole and the air supply hole. 
     
     
         13 . The humidifier of  claim 1 , wherein the humidifying device includes an exhaust tube that discharges humidified air produced in the humidifying device outside of the humidifying device. 
     
     
         14 . The humidifier of  claim 13 , further comprising a connecting tube that forms a connecting channel such that humidified air produced in the heating device flows to the humidifying device. 
     
     
         15 . The humidifier of  claim 14 , wherein the connecting tube is connected to a top surface of the heating device, and a first connecting hole through which humidified air produced in the heating device flows into the connecting tube is formed on the top surface of the heating device. 
     
     
         16 . The humidifier of  claim 1 , wherein an inner diameter of the first connection tube is larger than an inner diameter of the second connection tube. 
     
     
         17 . A humidifier, comprising:
 a heating device that heats water;   a humidifying device that is connected with the heating device and produces humidified air using water supplied from the heating device;   a first connection tube that connects the heating device and the humidifying device such that heated water in the heating device is supplied to the humidifying device;   a valve that opens/closes the first connection tube;   an exhaust tube that discharges humidified air produced in the humidifying device outside of the humidifying device; and   a blower fan that supplies air into the humidifying device.
