The injection hole 141 is preferably located in a range of 50 mm or less from the distance (D) from the center of the width direction of the nozzle assembly (60). If the distance (D) is greater than 50mm because the injection hole 141 is biased to one side because the sterilizing water can not be uniformly applied to the inner wall of the toilet bowl (10). On the other hand, the injection hole 141 may not be disposed within the half-width length of the nozzle assembly 50 from the center of the width direction of the nozzle assembly 60. This is because the injection hole 141 may not be disposed on the nozzle assembly 50. Since the width direction of the nozzle assembly 60 is typically 36 mm, the injection hole 141 is located in a range of 18 mm or more and 50 mm or less from the width direction center of the nozzle assembly 60.

The injection hole 141 of the sterilizing water spraying device 100 may be disposed to be inclined toward the front of the toilet bowl 10 directly below. Sterilization water can be uniformly sprayed on the entire inner wall of the toilet bowl 10 by directing the injection hole 141 located at the rear of the toilet bowl 10, the size of the conventional toilet bowl 10 and the sterilization water injection Considering the mounting position of the device 100, it is preferably installed inclined at an angle of 10 degrees or more and 45 degrees or less forward, and more preferably installed at an angle of 25 degrees.

3 is an exploded perspective view of the sterilizing water injection device 100 according to an embodiment of the present invention, Figures 4a and 4b is a side cross-sectional view of the sterilizing water injection device 100, Figure 5 is a view of the sterilizing water injection device 100 Bottom view of the body part.

3 to 5, the sterilizing water spraying apparatus 100 includes a body portion 120 and a nozzle portion 140.

Body portion 120 is provided with a hollow portion 121 through which the sterilizing water can flow, the inlet 122 is formed at the top, the outlet 123 is formed at the bottom, the inlet of the top of the body portion 120 The sterilized water introduced through the 122 is discharged through the outlet 123 via the hollow part 121.

The hollow part 121 extends in the longitudinal direction from the top to the bottom of the body portion 120, the outlet 123 extends in the radial direction from the bottom of the body portion 120 in fluid communication with the hollow portion 121. Therefore, the sterilizing water flows from the upper portion to the lower portion of the hollow portion 121 and is discharged in the radial direction. A plurality of outlets 123 may be formed along the circumference of the lower portion of the body part 120. In the illustrated example, two outlets 123 are disposed to face each other.

Below the outlet 123 is disposed, that is, the lower end of the body portion 120 is formed with a protrusion 124 having a larger diameter than the portion where the outlet 123 is disposed. The protruding portion 124 has a cylindrical shape, and a bottom thereof is concave to form the vortex generating chamber 130 together with the nozzle portion 140. Guide grooves 125 are formed on the sidewalls of the protrusions 124 so that the sterilized water discharged through the outlet 123 may be introduced. The guide groove 125 starting at the side wall of the protrusion 124 extends into the protrusion 124, which is formed to face away from the center of the protrusion 124. This is to give a rotational force to the sterilized water flowing along the guide groove 125 to form a vortex. Guide groove 125 is formed to be narrower from the side wall toward the inside. Therefore, the sterilizing water introduced into the vortex generating chamber 130 along the guide groove 125 may flow at high pressure and high speed to form a strong vortex. A plurality of guide grooves 125 may be formed. In the illustrated example, two guide grooves 125 are formed to face each other.

On the other hand, the bracket 120 is installed on the body portion 120 may be coupled to the front of the bidet device 20 with a screw or the like.

The nozzle unit 140 is a member coupled to the lower portion of the body portion 120 and is formed in a cylindrical shape. The injection hole 141 is formed at the center of the bottom surface of the nozzle unit 140. The inside of the bottom surface of the nozzle unit 140 forms the vortex generating chamber 130 together with the recessed portion of the protrusion 124. The outside of the bottom surface of the nozzle unit 140 may be formed in a tapered shape in which the thickness becomes thicker as it moves away from the injection hole 141. Forming the tapered shape outside the bottom of the nozzle unit 140 is required to shorten the length B of the injection hole 141 in order to increase the injection angle of the sterilizing water (to be described later), If the thickness of the entire bottom surface of the nozzle unit 140 is reduced to be the same as the length B of the hole 141, there is a problem that the rigidity of the bottom surface of the nozzle unit 140 is weakened, so that the length B of the injection hole 141 is reduced. Is shorter but thicker toward the outside.

Referring to the operation method of the sterilizing water injection device 100 configured as described above are as follows.

The sterilizing water introduced through the inlet 122 at the top of the body 120 is discharged in the radial direction of the body 120 through the outlet 123 provided in the lower portion of the body 120 through the hollow 121. . The sterilized water discharged through the outlet 123 is introduced into the vortex generating chamber 130 along the guide groove 125 of the protrusion 124 provided at the lower end of the body 120. Since the guide groove 125 is formed to extend in a direction other than the center of the vortex generating chamber 130 on the side wall of the vortex generating chamber 130, the sterilizing water introduced along the guide groove 125 is the vortex generating chamber 130. To form a vortex that rotates about its center. In particular, since the guide groove 125 becomes narrower toward the inside, the sterilizing water flowing along the guide groove 125 flows at a high pressure and a high speed to form a strong vortex, and the plurality of guide grooves 125 are disposed to face each other. As a result, vortices occur in two places and complement each other. The sterile water in which the vortex is generated in the vortex generating chamber 130 is discharged to the outside through the injection hole 141 disposed at the center of the bottom surface of the nozzle unit 140. At this time, since the sterilizing water discharged to the outside is the sterilized water in which the vortex is formed passes through the injection hole 141 at high pressure, the sterilizing water is sprayed to the outside as fine particles.

As such, when the sterilizing water is sprayed in the form of fine particles having a large surface area, the area in which the sterilizing water contacts the inner wall of the toilet becomes large, so that the sterilizing effect can be improved even in a small amount.

On the other hand, in order to spray the sterilizing water to the entire inner wall of the toilet bowl 10 with one sterilizing water spraying device 100, it is necessary to set the spray angle and the spraying speed of the sterilizing water sprayed from the spray hole 141 appropriately. . That is, the larger the spray angle and the spraying speed, the wider the sterilizing water can be sprayed.The smaller the spraying angle is, the smaller the spraying range is, the local spraying is made. Because.

Therefore, it is necessary to increase the spray angle and the spraying speed of the sterilizing water so that the sterilizing water can be sprayed on the entire inner wall of the toilet bowl 10, for this purpose, an optimal design for the sterilizing water spraying device 100 should be made. The present inventors experiment through the height (A) of the vortex generating chamber 130, the length (B) of the injection hole 141, the diameter (C) of the injection hole 141, and the width (D) of the guide groove 125 ) Is a parameter that affects the spray angle and the spray speed.

In order to find out the effect of these parameters on the injection angle and injection speed, the inventors carried out flow analysis simulations on various parameter values. The results are as follows.

A (mm) B (mm) C (mm) D (mm) Spray angle (degrees) Injection speed (m / s) One 0.2 0.2 One 0.5 140 5.562 2 0.2 0.2 1.2 0.5 120 5.128 3 0.3 0.2 One 0.5 100 4.483 4 0.3 0.6 One 0.5 90 4.163 5 0.2 0.6 1.2 0.5 70 3.213 6 0.2 0.6 One 0.5 - 2.110

Referring to the table above, in case of No. 1, the injection angle and injection speed are the largest, in case of No. 2, C is increased and the injection angle and injection speed are decreased, and in case of No. 3, the injection angle and injection speed is decreased. In the case of 4 to 6, when B was increased, it was found that the injection angle and the spraying speed were smaller. Therefore, it can be seen theoretically that the smaller the parameters A, B, and C, the inverse relationship between the injection angle and the injection speed becomes larger.

Based on the result that the injection angle and the injection speed are inversely proportional to the values of the parameters, the inventors actually determine the upper limit of parameters for the injection angle and the injection speed to be above a predetermined value (eg, the injection angle is 100 degrees or more). The experiment was conducted, and the following is a table of the results.

A (mm) B (mm) C (mm) D (mm) Spray angle Injection range One 0.1 0.1 One 0.5 More than 140 degrees More than 99% 2 0.2 0.2 One 0.5 More than 100 degrees over 90 3 0.3 0.2 One 0.5 More than 100 degrees over 90 4 0.5 0.2 One 0.5 20 degrees or less Less than 10% 5 0.5 0.1 1.2 0.5 20 degrees or less Less than 10% 6 0.2 0.3 One 0.5 More than 100 degrees over 90 7 0.2 0.5 One 0.5 20 degrees or less Less than 10% 8 0.2 One One 0.5 An ideal stream Less than 10% 9 0.5 One One 0.5 An ideal stream Less than 10% 10 0.2 One 1.2 0.5 An ideal stream Less than 10% 11 0.5 One 1.2 0.5 20 degrees or less Less than 10% 12 0.2 0.2 1.2 0.5 More than 100 degrees over 90 13 0.2 0.2 1.5 0.5 More than 100 degrees over 90 14 0.2 0.2 1.7 0.5 20 degrees or less Less than 10% 15 0.2 0.2 One 0.7 More than 100 degrees over 90 16 0.2 0.2 One One 20 degrees or less 0% 17 0.2 0.2 1.2 One 20 degrees or less Less than 10% 18 0.5 0.2 One One 20 degrees or less 0% 19 0.5 0.1 1.2 One 20 degrees or less Less than 10% 20 0.2 One 1.2 One 20 degrees or less Less than 10%

Referring to Nos. 2 to 4 of the above table, when B, C, and D are the same, the spray angle is 100 degrees or more and the spraying range is 90% or more of the inner wall of the toilet until A is 0.3 mm or less, but A is 0.5 mm. It can be seen that the spray angle is less than 20 degrees and the spray range is less than 10%. Therefore, A must be 0.3 mm or less in order to have an injection angle of 100 degrees or more and an injection range of 90% or more.

Referring to Nos. 2, 6 and 8 of the above table, when A, C, and D are the same, the injection angle is 100 degrees or more and the spraying range is 90% or more until B is 0.3 mm or less, but B is 0.5 mm or more. It can be seen that the spray angle is less than 20 degrees and the spray range is less than 10%. Therefore, B must be 0.3 mm or less in order to have an injection angle of 100 degrees or more and an injection range of 90% or more.

Referring to Nos. 2, 12 and 14 of the above table, when A, B, and D are the same, the spray angle is 100 degrees or more and the spraying range is 90% or more until C is 1.5 mm or less, but C is 1.7 mm. It can be seen that the spray angle is less than 20 degrees and the spray range is less than 10%. Therefore, C must be 1.5 mm or less in order to have an injection angle of 100 degrees or more and an injection range of 90% or more.

Referring to Nos. 2, 15, and 16 of the above table, when A, B, and C are the same, the spray angle is 100 degrees or more and the spraying range is 90% or more until D is 0.7 mm or less, but D is 1 mm. It can be seen that the injection angle is less than 20 degrees. Therefore, D must be 0.7 mm or less in order to have an injection angle of 100 degrees or more and an injection range of 90% or more.

Referring to No. 1 of the above table, it can be seen that when A, B, C, and D are the smallest, the injection angle is 140 degrees or more and the injection range is 99%. However, the remaining 5 times, 9 to 11, 17 to 20 are all when the at least one of A, B, C, D exceeds the range, the spray angle is 20 degrees or less and the spray range is less than 10% . For reference, in the spray angles in the above table, the abnormal water flow is a case where water is twisted and sprayed, and the spraying range is very small.

In summary, the height A of the vortex generating chamber 130 is 0.3 mm or less and the length B of the injection hole 141 is set so that the spray angle is 100 degrees or more and the spraying range is 90% or more. 0.3 mm or less, diameter C of the injection hole 141 should be 1.5 mm or less, and width D of the guide groove 125 should be 0.7 mm or less.

On the other hand, the smaller the parameters, the larger the injection angle, but considering the actual molding limit and cost, it is difficult to produce less than 0.1 mm, even if possible, the difference in effect is not large. Also, the larger the spray angle, the better, but cannot exceed 180 degrees.

In addition, the above experimental results appear when the pressure of the sterilizing water in the vortex generation chamber 130 is more than 1.2 kg / cm ² , when the pressure is less than that, the large injection angle and the injection range as shown in the experimental results do not come out. In this way, in order to maintain the pressure of the sterilizing water in the vortex generating chamber 130 above a predetermined value, it is preferable to design the size of the injection hole 141 smaller than the size of the inlet 122. However, if the pressure of the sterilizing water is excessively high, there is a risk of breakage of the components, so it is preferable that the pressure of the sterilizing water is not more than 5 kg / cm ² .

6 is a block diagram of a water supply system of the sterilizing water injection device 100 according to an embodiment of the present invention.

The process of spraying the sterilizing water spraying device 100 in the form of spray is as described above.

When cleaning the nozzle tip, you do not need to install a separate pump, but only a small amount of sterilizing water should be flowed through the nozzle tip at the original water pressure. Spray. However, as described above, since the sterilizing water spraying apparatus 100 according to the present invention sprays sterilizing water in the form of fine particles, only a small amount of sterilizing water (for example, about 50 ml) is required to sterilize the entire inner wall of the toilet. Therefore, a low capacity pump is sufficient, for example, a low noise high head diaphragm type pump can be applied.

As such, when supplying sterilizing water by applying pressure to the sterilizing water spraying device 100 instantaneously, the sterilizing water passing through the sterilizing water spraying device 100 may be sprayed into particles having a fine size through the spray hole 141. have.

The sterilizing water generating apparatus 200 may use an electrode module that generates sterilizing substance (mixed oxide: MO) from water itself by using an electric force and a ruthenium oxide catalytic electrode. Since generating sterilized water by the electrode method is a well-known matter, a detailed description thereof will be omitted.

The reactant addition device 220 may be connected to an inflow side of the sterilizing water generating device 200. The reactant adding device 220 may increase the amount of the sterilizing material generated by the sterilizing water generating device 200 by adding the reactant to the water flowing into the sterilizing water generating device 200. The reactant may be NaCl in the solid state.
