Sterilizing water dispensing apparatus, and bidet and toilet seat having the same

Abstract

A sterilizing water dispensing apparatus, and a bidet and toilet seat having the same are disclosed. The sterilizing water dispensing apparatus includes: an inlet to which sterilizing water is introduced; a cylindrical vortex production chamber that generates a vortex in the sterilizing water introduced through the inlet; and a dispensing hole disposed at the center of the bottom of the vortex production chamber and dispensing the vortex-produced sterilizing water in the vortex production chamber to an inner wall of the toilet. Because sterilizing water is dispensed in the form of fine particles with a relatively large surface area, the sterilizing water is brought into contact with a larger area of an inner wall of a toilet, so a sterilizing effect can be enhanced with a small quantity of sterilizing water. In addition, because sterilizing water can be dispensed to the entire surface of the inner wall of the toilet with a single sterilizing water dispensing apparatus by increasing a dispensing angle and dispensing speed of sterilizing water, the configuration can be simple and the cost can be reduced.

1 . A sterilizing water dispensing apparatus comprising:
 an inlet through which sterilizing water is introduced;   a cylindrical vortex production chamber that produces a vortex in the sterilizing water introduced through the inlet; and   a dispensing hole disposed at the center of the bottom of the vortex production chamber and dispensing the vortex-produced sterilizing water of the vortex production chamber to an inner wall of the toilet.   
     
     
         2 . The apparatus of  claim 1 , wherein the sterilizing water in the vortex production chamber is sprayed in the form of fine particles through the dispensing hole. 
     
     
         3 . The apparatus of  claim 1 , wherein the vortex production chamber comprises a guide groove extending from a side wall to the interior, the guide groove extending toward a position deviating from the center of the vortex production chamber, whereby sterilizing water is introduced to the interior of the vortex production chamber along the guide groove, producing a vortex rotating about the center of the vortex production chamber. 
     
     
         4 . The apparatus of  claim 3 , wherein the guide groove is formed such that its width narrows toward the interior from the side wall. 
     
     
         5 . The apparatus of  claim 3 , wherein a plurality of guide grooves are formed to be symmetrical about the center of the vortex production chamber. 
     
     
         6 . The apparatus of  claim 1 , wherein sterilizing water is dispensed through the dispensing hole at a dispensing angle of 100 degrees or greater. 
     
     
         7 . The apparatus of  claim 1 , wherein the vortex production chamber has a height ranging from 0.1 mm to 0.3 mm. 
     
     
         8 . The apparatus of  claim 1 , wherein the dispensing hole has a length ranging from 0.1 mm to 0.3 mm. 
     
     
         9 . The apparatus of  claim 1 , wherein the dispensing hole has a diameter ranging from 0.1 mm to 1.5 mm. 
     
     
         10 . The apparatus of  claim 3 , wherein the guide groove has a width ranging from 0.1 mm to 0.7 mm. 
     
     
         11 . The apparatus of  claim 1 , wherein the dispensing hole is smaller than the inlet. 
     
     
         12 . The apparatus of  claim 11 , wherein the pressure of sterilizing water within the vortex production chamber ranges 1.2 kg/cm 2  to 5 kg/cm 2 . 
     
     
         13 . A bidet comprising:
 the sterilizing water dispensing apparatus described in  claim 1 ; and   a sterilizing water generating apparatus that supplies sterilizing water to the sterilizing water dispensing apparatus.   
     
     
         14 . The bidet of  claim 13 , wherein the sterilizing water generating apparatus generates sterilizing water by an electrode method. 
     
     
         15 . The bidet of  claim 13 , further comprising:
 a nozzle assembly that dispenses water to the private parts of the user; and   a nozzle tip cleaning part that cleans a nozzle tip of the nozzle assembly,   wherein the sterilizing water generating apparatus is connected to the sterilizing water dispensing apparatus and the nozzle tip cleaning part, and sterilizing water generated by the sterilizing water generating apparatus is supplied to the sterilizing water dispensing apparatus or to the nozzle tip cleaning part.   
     
     
         16 . The bidet of  claim 15 , wherein the sterilizing water dispensing apparatus is connected to a pump, and sterilizing water is supplied by the pump. 
     
     
         17 . The bidet of  claim 16 , wherein the pump comprises:
 an electric motor;   a decelerating gear part connected with the electric motor and having a plurality of gears to decelerate a rotational speed;   a plurality of link members having one side coupled with the decelerating gear part and making a joint movement; and   a pumping unit connected with another side of the link members and reciprocally moving according to the joint movement of the link member,   wherein the pumping unit supplies sterilizing water of the sterilizing water generating apparatus to the sterilizing water dispensing apparatus while making a reciprocal movement.   
     
     
         18 . The bidet of  claim 13 , wherein a dispensing hole of the sterilizing water dispensing apparatus is installed to be sloped from a directly downward side to a front side. 
     
     
         19 . A toilet seat comprising:
 the sterilizing water dispensing apparatus described in  claim 1 ; and   the sterilizing water generating apparatus that supplies sterilizing water to the sterilizing water dispensing apparatus.   
     
     
         20 . The toilet seat of  claim 19 , wherein the sterilizing water generating apparatus generates sterilizing water by a solution method.
