  Such a configuration is the same as the configuration of a sterilization device applied to a general conventional toilet seat device. However, Embodiment 1 of the present invention is such a general toilet seat device in which the ultrasonic spray device 200 is provided in the toilet seat device body. In the ultrasonic spraying apparatus 200, the sterilized water that has passed through the flow valve 150 in the state where the toilet seat cover 300 is closed is made into fine particles 291 using the ultrasonic vibrator 260, and the fine particles 291 are removed. Bacteria water is sprayed on the toilet seat 400 and the toilet 500 side, and the sprayed sanitized water is allowed to flow down downward to wet the toilet seat 400 and the toilet 500, thereby eliminating bacteria.

  In addition, as shown in FIGS. 5 to 7, the ultrasonic spraying apparatus 200 is formed with a water inlet 220 for introducing the sterilized water that has passed through the flow valve on the side surface that is spaced a predetermined distance from the bottom surface 211 of the case 210. Yes. Further, in this ultrasonic spray device 200, a level sensor 230 that senses the level of sterilized water introduced through the water inlet 220 is formed in the case 210, and at a predetermined position on the bottom surface 211 of the case 210, The drainage part 240 which consists of a drainage hole of the diameter of the magnitude | size which drains disinfecting water with the drainage flow rate smaller than the incoming water flow rate introduce | transduced into the part 220 is formed.

  Further, in the ultrasonic spray device 200, an overflow portion 250 for adjusting the flow rate of the introduced sterilized water is formed at a position lower than the position of the water inlet portion 220. In addition, an ultrasonic transducer 260 that converts the sterilized water into fine particles 291 is provided on the bottom surface 211 of the case 210. Furthermore, a fan 270 that sucks and discharges external air is provided on the upper side surface of the case 210, and the air discharged by the fan 270 is guided on the upper side surface of the case 210 and the ultrasonic spray device 200. A guide piece 280 is formed to prevent the sterilized water from flowing to the fan 270 side in the case of falling. In addition, a spray port 290 is formed on the upper side surface of the case 210 for spraying fine particles 291 of sterilized water generated by the ultrasonic vibrator 260 to the toilet seat and toilet side with air guided by the guide piece 280.

Hereinafter, the operation of the sterilization apparatus in the toilet seat apparatus according to Embodiment 1 of the present invention configured as described above will be described in detail.
First, the used water that has passed through the stop cock 110 flows into the sterilized water generator 130 when the solenoid valve 120 is opened. The sterilized water generator 130 generates silver ions, and the generated silver ions are mixed with the used water flowing into the sterilized water generator 130 to generate sterilized water (silver ion water). Then, the generated sterilized water is discharged into the water tank 140 and stored.

  Thereafter, when the user operates the key for local or anal cleaning, the sterilized water (silver ion water) stored in the water tank 140 by the flow valve 150 flows into the anal cleaning unit 160 or the local cleaning unit 170. Then, it is discharged to the corresponding body part of the user, and anal cleaning or local cleaning is performed.

  The operation of the sterilization apparatus in the toilet seat apparatus described above is the operation of the sterilization apparatus in a conventional general toilet seat apparatus. However, in the sterilization apparatus for the toilet seat apparatus according to the present invention, when the toilet seat cover 300 is closed when the toilet seat apparatus is not used, the ultrasonic spray apparatus 200 is automatically activated, and a certain amount of sterilized water is generated. It is comprised so that it may spray on the toilet seat 400 and the toilet bowl 500 side.

  More specifically, the sterilized water (silver ion water) that has passed through the flow valve 150 is introduced into the ultrasonic spray device 200 by the water inlet 220 formed on the side surface that is spaced a predetermined distance from the bottom surface 211 of the case 210. Inflow. Here, the water inlet 220 may be formed as a simple through hole.

  While sterilized water is introduced from the incoming water portion 220 and sterilized water is drained through the drainage portion 240 formed at a predetermined position on the bottom surface 211, in this case, the drainage flow rate is relatively smaller than the incoming water flow rate. Yes. The role of the drainage unit 240 is to drain the sterilized water if it remains in the ultrasonic spraying apparatus 200 after the ultrasonic spraying is finished. That is, when sterilized water is stored in the ultrasonic spray device 200, if the main body of the toilet seat device is shaken by cleaning or the like, the sterilized water in the ultrasonic spray device 200 may flow into the toilet seat device main body. . In such a case, there is a risk of causing a failure of the toilet seat device. For this reason, when the spraying operation is completed, it is necessary to drain all the sterilized water remaining in the ultrasonic spraying apparatus 200. In addition, such a drainage part 240 can be easily implemented only by forming a through hole in the bottom surface 211 as described above.

  On the other hand, when the sterilized water enters the ultrasonic spray device 200, the level sensor 230 detects the level of the sterilized water to be introduced. The overflow unit 250 prevents sterilized water introduced into the ultrasonic spray device 200 from exceeding a certain amount. That is, when the sterilizing water introduced into the ultrasonic spraying device 200 exceeds a certain amount, the excess sterilizing water is allowed to flow to the toilet side through the drain port 251 of the overflow part 250, so that the ultrasonic spraying device 200 is always present. Ensure that the sterilized water stored inside does not exceed a certain amount. At the same time, the level sensor 230 detects the level of the sterilized water to be introduced, and if the sterilized water is filled up to a certain level as a result of the detection, the level sensor 230 generates a sterilized water sensing signal and controls the control means (not shown). ). Next, the control means operates the ultrasonic transducer 260 and operates the fan 270.

  The ultrasonic vibrator 260 turns the sterilized water stored by the ultrasonic vibration operation into the fine particles 291. The fine particles 291 are discharged from the spray port 290 together with the sucked external air by the operation of the fan 270. Thus, the air containing the fine particles 291 discharged by the fan 270 flows downward by the blocking piece 281 and is further turned upward by the guide piece 280. The blocking piece 281 and the guide piece 280 are for preventing the air (wind) discharged by the fan 270 from being blown out directly, reducing the wind speed, and transferring the air. The piece 280 also plays a role of preventing the sterilized water from flowing to the fan 270 or the other side when the toilet seat apparatus body falls down.

  Next, the sterilized water that has become the fine particles 291 through the ultrasonic vibrator 260 is sprayed to the outside through the spray port 290 by the air guided by the guide piece 280. The sprayed sterilized water hits the toilet seat cover 300 and naturally flows down, and wets the toilet seat 400 and the toilet bowl 500, so that the toilet seat 400 and the toilet bowl 500 are sterilized.

However, the following configuration is different. That is, a sterilizing liquid input device 600 is provided between the flow valve 150 and the ultrasonic spray device 200. That is, the sterilizing water is made by introducing the sterilizing liquid into the used water until the used water discharged from the flow valve 150 flows into the ultrasonic spray device 200. In the second embodiment, as in the case of the first embodiment, the ultrasonic spray device 200 uses the ultrasonic vibrator 260 to remove the sterilized water while the toilet seat cover 300 is closed. By forming the fine particles 291 and sterilizing water converted into the fine particles 291 onto the toilet seat 400 and the toilet bowl 500 side, the sprayed sterilized water is allowed to flow down naturally to wet the toilet seat 400 and the toilet bowl 500, and The toilet bowl 500 is sterilized and disinfected.
