         10 . The humidifier of  claim 9 ,
 wherein the guide rim includes a fastening rib that is provided at a lower end of the inner peripheral wall,   wherein the guide cover includes:
 a border wall that is spaced outwardly from an outer circumference of the guide plate and is coupled to the guide rim; and 
 a fastening stopper that is defined at an upper end of the border wall, and wherein the fastening rib is detachably coupled to the fastening stopper. 
   
     
     
         11 . The humidifier of  claim 1 , further comprising:
 a case having an open upper side; and   wherein a humidifying device that receives the water from the water tank and generates the humidified air is disposed inside the case, and   wherein the water tank is disposed above the humidifying device, and a discharge flow path through which humidified air flows is defined between the case and the water tank.   
     
     
         12 . The humidifier of  claim 11 ,
 wherein the water tank cover includes:
 a guide rim that is disposed above the upper end of the water tank extends along at least a portion of the circumference of the upper end of the water tank; and 
 a guide cover that is coupled to the guide rim and covers the upper side of the water storage space, 
   wherein the guide rim includes a guide slope surface inclined downward toward a center of the guide cover, and   wherein an outer circumference of the guide slope surface is positioned further outward in a horizontal direction relative to the upper end of the water tank.   
     
     
         13 . The humidifier of  claim 12 ,
 wherein the case includes:
 an outer shell that is spaced horizontally outward from the water tank; and 
 an inner shell that is disposed inside the outer shell and that accommodates the water tank, 
   wherein the discharge flow path includes:
 a first discharge flow path that is defined between the water tank and the inner shell and through which the humidified air flows; and 
 a second discharge flow path that is defined between the inner shell and the outer shell, and 
   wherein the outer circumference of the guide slope surface is positioned further inward in the horizontal direction relative to an upper end of the inner shell.   
     
     
         14 . The humidifier of  claim 13 , wherein the inner shell has a shell inlet through which the humidified air is received from the humidifying device.
