1 illustrates a toilet 10 having a sterilizing water spraying device 100 according to an exemplary embodiment of the present invention.

Referring to FIG. 1, a bidet 20 is installed at an upper portion of the toilet 10. The bidet 20 includes a bidet body 30, and the toilet seat 30 is hinged to the toilet seat 40 and the cover 50 to be rotatable. The toilet seat 40 is formed in a ring shape so that the user can sit and see the toilet, there may be a heater for heating the toilet seat 40 to an appropriate temperature. The cover 50 is formed in a shape corresponding to the toilet seat 40 so that the open part of the annular toilet seat 40 can be closed when the toilet seat 10 is not used.

The nozzle assembly 60 and the drying apparatus 70 are installed in the bidet body 30. The nozzle assembly 60 includes an anal cleansing nozzle and a female bidet nozzle. The cleaning nozzle and the bidet nozzle are provided to be movable in the front of the bidet main body 30, respectively. At the front end portions of the cleaning nozzle and the bidet nozzle, nozzle tips each having a discharge port are mounted to spray the washing water.

The drying apparatus 70 includes a blower fan, a blower duct, and a heating device, and may discharge hot air toward the front of the bidet body 30.

The operation unit 80 is installed at one side of the bidet body 30, and the user may control the operation of the bidet 20 through the operation unit 80. That is, when the cleaning button or the bidet button is pressed after the toilet, the cleaning nozzle or the bidet nozzle may move forward to spray the washing water to the user's local part, and after washing, pressing the drying button may cause the warm air to be sprayed onto the local part. You can remove the water.

In front of the bidet body 30, the sterilizing water injection device 100 is further provided. The sterilizing water spraying device 100 is a device for sterilizing the inner wall of the toilet 10 by spraying sterilizing water on the inner wall of the toilet 10 by receiving sterilizing water from the sterilizing water generating device. The sterilizing water spraying device 100 is preferably mounted to the bidet body 30 so that the spray hole is inclined toward the front of the toilet 10 directly below. Sterilizing water can be uniformly sprayed on the entire inner wall of the toilet 10 by directing the injection hole located in the rear of the toilet 10, the size of the conventional toilet 10 and the mounting of the sterilizing water injection device 100 Considering the position, it is preferable to install inclined more than 20 degrees forward. Alternatively, the sterilizing water spraying device 100 may be installed to be movable in the front of the bidet body 30 like the bidet nozzle. In this case, the sterilizing water spraying device 100 may not need to be inclined so that the spraying hole may face the front. On the other hand, the sterilizing water injection device 100 can also be performed by the operation unit 80 to perform the injection operation. That is, a button for disinfecting the toilet is provided on the operation unit 80, and when the user presses the toilet sterilization button, the sterilizing water spraying device 100 may spray sterilizing water.

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

2 to 4, 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 protrusion 124 has a cylindrical shape, and the bottom surface is concave to form the vortex generating chamber 130 together with the nozzle unit 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 body 30 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 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, so that the local spraying is performed. If the spraying speed is small, the sterilizing water sprayed is not extended far. to be.

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 10, the optimal design for the sterilizing water injection device 100 should be made for this purpose. The inventors experimented with 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. It was found that this parameter affects the injection angle and injection 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.

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 .

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

Referring to FIG. 5, the water supply system is configured to distribute the raw water to each component through the flow path control device 300. Raw water may be supplied by a water pipe or a water supply tank 400.

When the user performs the function of washing or bidet, the raw water is supplied to the washing nozzle 62 or the bidet nozzle 64 and the washing water is sprayed through the nozzle.

When the user executes the nozzle tip cleaning function, the raw water becomes sterilized water while passing through the sterilizing water generating device 200 and then is supplied to the nozzle tip cleaning unit 66. The sterilizing water supplied to the nozzle tip cleaner 66 is sprayed onto the nozzle tip to clean the nozzle tip.

When the user executes the toilet sterilization function, the raw water is supplied to the sterilizing water generating device 200 and the raw water is sterilizing water in the sterilizing water generating device 200. When a predetermined amount of time has elapsed and a desired amount of sterilizing water is generated, the pump 240 connected to the sterilizing water generating device 200 is operated to allow the sterilizing water to flow into the sterilizing water spraying device 100. The sterilizing water introduced into the sterilizing water spraying device 100 is sprayed on the inner wall of the toilet 10 to sterilize the toilet 10. 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.

6 shows another form of pump 240. Referring to FIG. 6, the pump 240 is coupled to the electric motor 241 and has a reduction gear unit 242 having a plurality of gears to reduce the rotational speed of the electric motor 241, and the reduction gear unit 242.

The pumping unit 244 may be instantaneously pumped while reciprocating by the link member 243 to supply the sterilizing water of the sterilizing water generating device 200 to the sterilizing water spraying device 100. 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.

The reactant is accommodated in the reactant adding device 220, mixed with water flowing into the reactant adding device 220, and introduced into the sterilizing water generating device 200. In the sterilizing water generating apparatus 200, electricity is applied to water mixed with NaCl to generate HOCl ⁻ or OCl ⁻ ions, which are sterilizing substances. In addition to NaCl, substances such as chlorine series, silver oxide, and iodine series may be introduced into the sterilizing water generating device 200.
