Sterilizing water which has introduced through the inlet 122 formed at the upper end of the body part 120 flows along the hollow part 121 and then is discharged through the outlet 123.
  • the hollow part 121 extends in a lengthwise direction from the upper portion of the body part 120 to the lower portion of the body part 120, and the outlet 123 extends in a radial direction from the lower portion of the body part 120 so as to be fluid-connected with the hollow part 121. Accordingly, the sterilizing water flows from the upper portion to the lower portion of the hollow part 121 and then is discharged in the radial direction.
  • a plurality of outlets 123 may be formed along the lower circumference of the body part 120, and in the present exemplary embodiment illustrated in the drawings, two outlets 123 are disposed in a facing manner.

  • the protruding part 124 has a diameter larger than the part the outlet 123 is formed on.
  • the protruding part 124 in a cylindrical shape has a recessed bottom surface to form a vortex production chamber 130 together with the nozzle part 140.
  • a guide groove 125 is formed at a side wall of the protruding part 124 to allow sterilizing water which has been discharged through the outlet 123 to be introduced therein.
  • the guide groove 125 starting from the side wall of the protruding part 124, extends to the interior of the protruding part 124, and is formed to point toward a position deviating from the center of the protruding part 124.
  • This configuration aims to providing a rotational force to the sterilizing water introduced along the guide groove 125 to thus produce a vortex.
  • the guide groove 125 is formed such that its width narrows toward the interior from the side wall. Accordingly, the sterilizing water introduced into the vortex production chamber 130 along the guide groove 125 can flow at a high pressure and at high speed to produce a strong vortex.
  • a plurality of guide grooves 125 may be formed, and in the present exemplary embodiment illustrated in the drawings, two guide grooves 125 are formed in a facing manner.
  • a bracket 126 is installed on the body part 120 and coupled to a front portion of the main body 30 of the bidet apparatus with a screw or the like.

  • An inner side of the bottom of the nozzle part 140 forms the vortex production chamber 130 together with the recessed portion of the protruding part 124.
  • An outer portion of the bottom of the nozzle part 140 may be formed to be tapered such that the thickness increases as it goes away from the dispensing hole 141.
  • the reason for forming the tapered outer portion of bottom of the nozzle part 140 is due to the fact that the length (B) of the dispensing hole 141 needs to be short in order to increase a dispensing angle for dispensing sterilizing water (to be described) and, in this case, if the thickness of the entire bottom of the nozzle part 140 is as small as to be equal to the length (B) of the dispensing hole 141, the rigidity of the bottom of the nozzle part 140 weakens, so the length (B) of the dispensing hole 141 remains short while the thickness of the outer portion of the bottom of the nozzle part 140 increases toward the outer side.
  • Sterilizing water introduced through the inlet 122 at the upper end of the body part 120 passes along the hollow part 121 and is then discharged in the radial direction of the body part 120 through the outlet 123 provided at the lower portion of the body part 120.
  • the sterilizing water which has been discharged through the outlet 123 is introduced into the vortex production chamber 130 along the guide grooves 125 of the protruding part 124 formed at the lowermost portion of the body part 120.
  • the guide groove 125 is formed to extend in a direction other than towards the center of the vortex production chamber 130 from the side wall of the vortex production chamber 130, so the sterilizing water introduced along the guide groove 125 forms a rotating vortex centered on the center of the vortex production chamber 130.
  • the sterilizing water flowing along the guide grooves 125 can flow at a high pressure and at a high speed to form a strong vortex.
  • the plurality of guide grooves 125 are disposed to face each other, vortexes are produced from two places, complementing each other.
  • the sterilizing water with the vortexes produced in the vortex production chamber 130 is externally discharged through the dispensing hole 141 disposed at the center of the bottom of the nozzle part 140. At this time, the externally discharged sterilizing water, namely, the vortex-formed sterilizing water, passes through the dispensing hole 141 at a high pressure, to become fine particles being sprayed to the outer side.
  • the sterilizing water when the sterilizing water is sprayed in the form of fine particles with a large surface area, the sterilizing water can be brought into contact with a larger area of the inner wall of the toilet, having the advantage of enhancing the sterilizing effect even with the small quantity of sterilizing water.
  • the single sterilizing water dispensing apparatus 100 in order to spray the sterilizing water to the entire surface of the inner wall of the toilet 10 by using the single sterilizing water dispensing apparatus 100, it is required to properly set a dispensing angle and a dispensing speed of the sterilizing water dispensed from the dispensing hole 141. Namely, as the dispensing angle widens and the dispensing speed becomes high, sterilizing water can be dispensed widely, and if the dispensing angle is small, the dispensing range is reduced to perform partial dispensing, while if the dispensing speed is low, the dispensed sterilizing water could not extend for a desirable distance (i.e., it could not reach sufficiently far).
  • the dispensing angle and dispensing speed of sterilizing water needs to be increased so that the sterilizing water can be dispensed to the entire surface of the inner wall of the toilet 10, for which the sterilizing water dispensing apparatus 100 must be thus optimally designed.
  • the inventors of the present invention found through an experimentation that the height (A) of the vortex production chamber 130, the length (B) of the dispensing hole 141, the diameter (C) of the dispensing hole 141, and the width (D) of the guide groove 125 are parameters affecting the dispensing angle and the dispensing speed.
  • the first case shows the largest dispensing angle and the highest dispensing speed.
  • the second case when the diameter (C) of the dispensing hole 141 was increased, the dispensing angle was reduced and the dispensing speed was lowered.
  • the third case when the height (A) of the vortex production chamber 130 was increased, the dispensing angle was reduced and the dispensing speed was lowered.
  • the fourth to sixth cases when the length (B) of the dispensing hole 141 was increased, the dispensing angle was further reduced and the dispensing speed was further lowered. Consequently, it should be noted that as the parameters A, B, and C are reduced, the dispensing angle and the dispensing speed are increased, establishing inverse proportional relationships.
  • the inventor of the present invention conducted actual experimentation, the results of which are shown in the table below:
  • the dispensing angle is 100 degrees or greater and the dispensing range is 90% or greater of the inner wall of the toilet, until when A is 0.3 mm or smaller, while if A is 0.5 mm, the dispensing angle is 20 degrees or lower and the dispensing range is smaller than 10%.

  • the diameter (C) of the dispensing hole 141 must be 1.5 mm or smaller
  • the width (D) of the guide groove 125 must be 0.7 mm or smaller.
  • the dispensing angle can be increased by reducing the parameters, but in consideration of molding limitations and costs, the fabrication of a dispensing hole with the parameters A, B, C, and D of 0.1 mm or smaller is not easy, and if realized, there is not a great deal of difference in its effects.
  • the above experimental results can be obtained when the pressure of sterilizing water within the vortex production chamber 130 is 1.2 kg/cm 2 or greater. That is, such large dispensing angle and dispensing range as in the experimental results cannot be obtained at a lower pressure.
