Humidifier

Abstract

The humidifier of the present disclosure includes: an inner tank that forms a space in which water is held and includes a bottom wall in which a bottom hole is formed; and a connector that passes through the bottom hole and is connected to the inner tank. A bottom hole through which the connector passes is formed on the bottom wall. A first groove spaced apart from the bottom hole in a radial direction and formed in a ring shape, and a plurality of second grooves radially extending so as to intersect the first groove are formed on the bottom wall of the inner tank.

What is claimed is: 
     
         1 . A humidifier comprising:
 an inner tank forming a space for storing water and including a bottom wall having a bottom hole; and   a connector penetrating the bottom hole and connected to the inner tank,   wherein a bottom hole penetrated by the connector is formed on the bottom wall, and   wherein the bottom wall of the inner tank has a first groove spaced apart from the bottom hole in a radial direction and formed in a ring shape, and a plurality of second grooves extending radially to intersect the first groove.   
     
     
         2 . The humidifier of  claim 1 , wherein the first groove and the plurality of second grooves protrude upward on the bottom wall. 
     
     
         3 . The humidifier of  claim 1 , wherein each of the plurality of second grooves is spaced apart from the bottom hole. 
     
     
         4 . The humidifier of  claim 1 , wherein a radial length of each of the plurality of second grooves is formed to be longer than a width of the first groove. 
     
     
         5 . The humidifier of  claim 1 , wherein the plurality of second grooves consist of eight to twelve grooves. 
     
     
         6 . The humidifier of  claim 1 , wherein the bottom wall of the inner tank has a third groove formed around the bottom hole. 
     
     
         7 . The humidifier of  claim 6 , wherein the third groove intersects the plurality of second grooves. 
     
     
         8 . The humidifier of  claim 1 , wherein each of the plurality of second grooves includes a second- 1  groove extending inward in the radial direction from the first groove and a second-2 groove extending outward in the radial direction from the first groove. 
     
     
         9 . The humidifier of  claim 8 , wherein a radial length of the second-1 groove is formed to be longer than a radial length of the second-2 groove. 
     
     
         10 . The humidifier of  claim 1 , wherein the inner tank includes
 a circumferential wall extending upward from an outer circumferential end of the bottom wall, and   an extension wall having a bent shape to connect the circumferential wall and the bottom wall, and   wherein the first groove is placed closer to the outer circumferential end than to an inner circumferential end of the bottom wall.   
     
     
         11 . The humidifier of  claim 1 , wherein a packing is disposed around the bottom hole in the bottom wall. 
     
     
         12 . The humidifier of  claim 11 , wherein the connector includes
 a connector body disposed to penetrate the bottom hole, and   a connector holder disposed outside the inner tank and coupled to the connector body, and   wherein when the connector holder is coupled to the connector body, the packing is in contact with the connector body.   
     
     
         13 . The humidifier of  claim 1 , wherein a handle is disposed at an upper end portion of the inner tank,
 wherein the handle includes a handle fixing portion connected to the inner tank, and a handle bar crossing the handle fixing portion, and   wherein the handle fixing portion is disposed to cover an outer circumference of the inner tank.   
     
     
         14 . The humidifier of  claim 13 , wherein the handle fixing portion includes an outer wall disposed outside the inner tank and an inner wall disposed inside the inner tank, and
 wherein the inner wall is coupled to the inner tank, and the outer wall is disposed to be spaced apart from a circumferential wall of the inner tank.   
     
     
         15 . The humidifier of  claim 14 , wherein a water tank sealer is disposed on an outer circumferential surface of the outer wall, and the water tank sealer protrudes outward from the outer circumferential surface of the outer wall. 
     
     
         16 . A humidifier comprising:
 an inner tank forming a space for storing water and including a bottom wall having a bottom hole; and   a connector penetrating the bottom hole and connected to the inner tank,   wherein a bottom hole penetrated by the connector is formed on the bottom wall,   wherein a groove protruding upward is formed on the bottom wall of the inner tank, and   wherein the groove is formed to be symmetric around the bottom hole in a circumferential direction.   
     
     
         17 . The humidifier of  claim 16 , wherein the groove includes a concave portion and a convex portion are continuously formed.
