Each of the mesh 71 and the mesh 72 corresponds to a filter, and the cassette case 70 corresponds to a disinfectant container.

As shown in FIG. 6, a sterilizing agent 73 is accommodated inside the cassette case 70. This disinfectant 73 refers to an aggregate of a plurality of disinfecting glass composed of a slow-dissolving phosphoric acid-based glass solid solution having a metal element uniformly, and includes a butt cleaning port 50, a bidet cleaning port 52, and a toilet bowl. From each of the cleaning port 53 and the nozzle cleaning port 60, cleaning water having a sterilizing effect is ejected. Each of these sterilization glasses has a larger block shape than the mesh 71 and the mesh 72, and each sterilization glass cannot escape to the outside of the cassette case 70 through the mesh 71 and the mesh 72. The through holes of the butt cleaning port 50, the through holes of the bidet cleaning port 52, the through holes of the toilet cleaning port 53, and the nozzle cleaning port 60 are set to be larger than the diameter of the mesh 71. And larger than the hole diameter of the mesh 72. Each of these sanitizing glasses contains about 3% (wt%) silver oxide, about 27% (wt%) zinc oxide, about 1% (wt%) cobalt oxide, and about 69% (wt%) calcium phosphate. It contains. In general, borosilicate glass mainly composed of SiO ₂ and B ₂ O ₃ and phosphate glass mainly composed of P ₂ O ₅ are known as soluble glass. Phosphoric glass with high slow solubility is used. For this reason, since the antibacterial effect of each sterilization glass lasts for a long period of time, it is possible to prevent the scale (scale) from adhering to the toilet 1 and the hot water heater 41, respectively.

When a toilet seat device equipped with a heating device that raises the temperature of the washing water to increase the washing power is used for a long time, evaporation residue components (scales) such as calcium, magnesium, and silicic acid contained in the tap water are contained in the hot water heater 41. It deposits on each of the surface and the surface of the water temperature sensor 43 and deposits on each of the surface of the hot water heater 41 and the surface of the water temperature sensor 43. When this scale is accumulated, the heating efficiency of the hot water heater 41 is lowered and accurate temperature measurement by the water temperature sensor 43 is disabled, so that the temperature control of the hot water heater 41 cannot be performed normally. When this scale is deposited on the toilet 1, it becomes a cause of exacerbation of dirt, so that dirt further accumulates starting from the scale and it is easy for wrinkles to occur. Become. On the other hand, when the phosphate component contained in each sterilized glass is dissolved in water, chelate structures (Ca ₂ P ₆ O ₁₈ ²⁻ , Mg ₂ P ₆ O ₁₈ ²⁾ for calcium and magnesium in tap water, respectively. ^- ) To increase the water solubility of the calcium component, so that each of calcium carbonate and calcium silicate is prevented from depositing as a scale. Therefore, accurate temperature measurement by the water temperature sensor 43 can be continuously performed over a long period of time, and scales can be prevented from adhering to the toilet bowl 1, so that the cause of wrinkles can be eliminated.

The phosphoric acid component (P ₂ O ₅ ) having solubility in washing water in each sterilized glass has both the effect of maintaining the transparency of the sterilized glass and the effect of removing silver ions in the washing water. Yes. When the concentration of the phosphoric acid component is less than 10 weight percent, the mechanical strength of the sterilized glass cannot be maintained, and when it exceeds 80 weight percent, the mechanical strength of the sterilized glass may be reduced. There is. For this reason, the content of the phosphoric acid component in each sterilized glass is preferably 10 to 80% by weight, and more preferably 30 to 70% by weight.

  When silver ions, which are antibacterial components, are combined with anions in tap water, especially chloride ions and sulfide ions, a salt with a low solubility product is produced, so the solubility is reduced and silver ions, which are antibacterial components, are released into the water. It becomes difficult. For this reason, an effective component may not elute and an antimicrobial effect may fall. On the other hand, the cleaning water in the case 2 has a phosphoric acid component eluted from the antibacterial glass as an anion. For this reason, since the silver ion eluted without forming a hardly soluble salt can be stably maintained in a state having an antibacterial effect, the antibacterial effect is sustained. Therefore, since an effective antibacterial effect can be exhibited even at a relatively low concentration, the cost of the disinfectant 73 can be reduced. At the same time, a blackening phenomenon peculiar to silver ions (a phenomenon in which a substance or the like attached by changing to metallic silver when the silver ions are high in concentration) is reduced.

Silver oxide is eluted as silver ions in the washing water and exhibits antibacterial or antibacterial effects. Cobalt oxide is added as a metal oxide that colors the sterilized glass in blue, and the sterilized glass becomes vivid blue even at a very low content of about 0.01%. Recognition. Specifically, the sterilizing glass may contain 1 to 5 percent by weight of Ag ₂ O and 10 to 90 percent by weight of the phosphate component, and the content of Ag ₂ O is determined according to the necessary antibacterial action. It ’s fine. That is, when Ag ₂ O is 0.1 weight percent or less, the antibacterial glass cannot substantially obtain the antibacterial action, and when Ag ₂ O is 5 weight percent or more, the bacteria removal glass is likely to turn brown. Further, since the production cost becomes high, it is preferable to adjust the content of Ag ₂ O in the sterilized glass within the range of 0.1 weight percent to 5 weight percent. In addition, you may contain about 0 to 50 weight percent of zinc oxide or cerium oxide having antibacterial action. Each of these zinc oxide and cerium oxide is useful for preventing browning of the sterilized glass, and is expected to have an effect of removing microorganisms and fungi that are not in contact with silver ions but suppressing the growth of microorganisms and fungi. it can. However, if the content of each of zinc oxide and cerium oxide exceeds 50 weight percent, the sterilized glass may be discolored. Therefore, the content of each of zinc oxide and cerium oxide should be suppressed to 50 weight percent or less. Is preferred.

  Each sterilizing glass may be either a disk shape having a size of about 10 mm and a thickness of about 5 mm, or a rectangular shape having a corner of about 5 mm square, and its weight is several grams. A total of 200 g of sterilized glass is stored inside the cassette case 70. The size of each of these sterilization glasses can be used in a state in which the concentration of silver ions sufficient to exert antibacterial action in the wash water inside the case 2 can be continued for more than 10 years exceeding the average life of the toilet seat device. In view of the above, it is calculated and optimized based on the dissolution rate of the sterilized glass obtained experimentally. As a result of this calculation, the concentration of silver ions released from the sterilized glass after 10 years is about 90% of the initial concentration, but this concentration has a sufficient antibacterial effect. That is, when the zeolite and apatite are impregnated with silver ions, the dissolution rate changes greatly, but the sterilized glass has the sterilized components uniformly dispersed up to the inside, and the solid solution itself is removed. Since the disinfecting component is released on the basis thereof, the concentration change is extremely small. Moreover, the sterilization glass is formed into a disk shape or a rectangle with a corner cut off. For this reason, it is possible to prevent the sterilized glass from being crushed and leaked by the impact of the washing water pressure. Moreover, in order to suppress that the burr | flash etc. when shape | molding sanitization glass remove | eliminate unnecessarily from sanitization glass, a corner | round may be rounded or it may grind | polish with a barrel.

  Silver ions exhibit an antibacterial effect even at concentrations as low as 1 ppb. This is because the dissolved silver ions are combined with the resin that is the base material of the nozzle 49 for the buttocks, the resin that is the base material of the nozzle 51 for the bidet, and the glass component on the surface of the toilet 1 and are concentrated on the surface. to cause. Each of these adsorptions does not easily drop, and can be maintained in a state where silver ions having a substantially constant concentration are adhered to the surface over a long period of time by constantly washing with water having a sterilizing component. FIG. 7 is a graph showing the correlation between silver ions in the wash water and the number of days elapsed. The solid line in FIG. 7 experimentally obtains the correlation between the silver ions in the washing water and the elapsed days when the toilet seat device is used 20 times a day after storing about 200 g of sterilized glass in the cassette case 70. The arrow indicates the silver ion concentration (1 ppb) at which the sterilization effect can be sufficiently obtained with the washing water. As is apparent from FIG. 7, the effective concentration of silver ions can be maintained even after 10 years.

  Calcium phosphate dissolves very slowly in the wash water, and silver ions elute slowly over a long period of time. For this reason, the antibacterial effect can be maintained without performing maintenance for the user to replace the sanitized glass by selecting each of the necessary amount and the optimum size of the sanitized glass. However, the sterilization glass may be exchanged together with the cassette case 70 when the usage frequency is high and maintenance is required. In this case, if the cassette case 70 is formed of a transparent material so that the sterilization glass inside the cassette case 70 can be confirmed from the outside, and the sterilization glass is colored with cobalt oxide or the like, the presence or absence of the sterilization glass can be easily achieved. Can be confirmed. The colorant has a concentration that does not harm the human body and may be an inorganic pigment or the like. For example, the same effect can be obtained by adding any pigment such as copper oxide, iron oxide, manganese oxide and talc. In particular, when colored with copper oxide, the copper ion itself also has an antibacterial action, so a synergistic effect can be expected.

  8 and 9 are flowcharts showing the operation control program recorded in advance in the ROM 12 of the control circuit 10, and the CPU 11 of the control circuit 10 determines the operation state of the ejection pressure switch 8 in step S1 of FIG. For example, when the user operates the ejection pressure switch 8, the process proceeds from step S <b> 1 to step S <b> 2, and the ejection pressure of the washing water is set according to the operation content of the ejection pressure switch 8. Then, the rotation amount of the opening degree adjusting motor 63 is set according to the setting result of the ejection pressure, and the opening degree of the flow rate adjusting valve 56 is set based on driving the opening degree adjusting motor 63 according to the setting result of the rotation amount. It is set according to the operation content of the ejection pressure switch 8.

  CPU11 will judge the operation state of the water temperature switch 7, if it transfers to step S3 of FIG. For example, when the user operates the water temperature switch 7, the process proceeds from step S <b> 3 to step S <b> 4, and the cleaning water temperature is set according to the operation content of the water temperature switch 7. Then, the output of the hot water heater 41 is set according to the setting result of the water temperature, and the water temperature of the cleaning water is set according to the operation content of the water temperature switch 7 based on the driving of the hot water heater 41 according to the setting result of the output. To do.

  When the CPU 11 proceeds to step S5 in FIG. This step S5 corresponds to a determination means. For example, when the user places a buttocks on the toilet seat 16, the CPU 11 determines that there is a user based on the presence of the presence signal from the presence sensor 21 in step S5. In step S6, it is determined whether the butt switch 4 is turned on or off. In step S8, whether the bidet switch 5 is turned on or off is determined. For example, when the user operates the buttocks switch 4 with the buttocks on the toilet seat 16, the CPU 11 determines that the buttocks switch 4 is turned on in step S6, turns on the buttocks flag in step S7, and proceeds to step S9. . When the user operates the bidet switch 5 with the buttocks on the toilet seat 16, the CPU 11 determines that the bidet switch 5 is turned on in step S8, and proceeds to step S9.

  In step S9, the CPU 11 drives the nozzle motor 54 in the forward direction by the maximum amount recorded in advance in the ROM 12. The maximum amount is a value for moving each of the buttocks nozzle 49 and the bidet nozzle 51 from the retreat position to the advance position. Each of the buttocks nozzle 49 and the bidet nozzle 51 has a nozzle motor 53 in step S9. Is moved from the reverse position to the forward position based on the operation of.

  When the CPU 11 moves each of the buttocks nozzle 49 and the bidet nozzle 51 from the backward position to the forward position in step S9, the CPU 11 determines the setting state of the buttocks flag in step S10. When it is determined in step S10 that the buttocks flag is turned on, the buttocks flag is turned off in step S11, and the switching valve motor 61 is rotated in step S12 to clean the buttocks of the flow rate adjusting valve 56. Open the output port alternatively. When it is determined in step S10 that the bottom flag is turned off, the process proceeds to step S13, and the bidet cleaning output port of the flow rate adjustment valve 56 is selected based on the rotational operation of the switching valve motor 61. To open.

  When the CPU 11 opens the butt cleaning output port or the bidet cleaning output port of the flow rate adjusting valve 56, the CPU 11 sends air to the flow rate adjusting valve 56 based on driving the pump motor 66 in step S14. And it transfers to step S15 and the on-off valve solenoid 33 is open | released. That is, when the user operates the buttocks switch 4, in step S15, warmed wash water containing antibacterial components is sprayed from the buttocks washing port 50 of the buttocks nozzle 49 to the user's anus. When the user operates the bidet switch 5, in step S <b> 15, warmed cleaning water containing an antibacterial component is sprayed from the bidet cleaning port 52 of the bidet nozzle 51 to the user's local area and the bidet nozzle 51. The flushed wash water containing the antibacterial component is sprayed from the toilet flushing port 53 to the toilet 1. This step S15 corresponds to a cleaning process starting means.

  When the CPU 11 opens the on-off valve solenoid 33 in step S15, the CPU 11 determines whether the stop switch 6 is on or off in step S16. For example, when the user operates the stop switch 6, the CPU 11 determines that the stop switch 6 is turned on in step S16, stops the operation of the pump motor 66 in step S17, and closes the on-off valve solenoid 33 in step S18. Stop the flushing operation. This step S18 corresponds to a cleaning process stop means.

  When the CPU 11 closes the on-off valve solenoid 33 in step S18, the butt nozzle 49 and the bidet nozzle 51 are moved from the forward position to the backward position based on driving the nozzle motor 54 in the reverse direction by the maximum amount in step S19. Move to. In step S20, the nozzle cleaning output port of the flow rate adjusting valve 56 is selectively opened based on the rotational operation of the switching valve motor 61. In step S21, the on-off valve solenoid 33 is opened. In the open state of the on-off valve solenoid 33, warmed cleaning water containing antibacterial components is ejected from the nozzle cleaning port 60, and the bottom cleaning port 50 of the buttocks nozzle 49 and the bidet nozzle 51 are cleaned for bidet. Each of the mouths 52 is sprayed with warmed washing water containing an antibacterial component.

  When the CPU 11 opens the on-off valve solenoid 33 in step S21, the timer T is reset to “0” in step S22 of FIG. 9, and the presence or absence of a clock signal is determined in step S23. This clock signal is output from the clock circuit inside the control circuit 10 at a constant time interval. When the CPU 11 determines that there is a clock signal in step S23, the process proceeds to step S24, and the timer T stores the ROM 12 in the timer T. The unit value recorded in advance is added.

  When adding the timer T in step S24, the CPU 11 compares the addition result of the timer T with a nozzle cleaning stop time (for example, 10 seconds) recorded in advance in the ROM 12 in step S25. Here, when it is determined that the addition result of the timer T has reached the nozzle cleaning stop time, the process proceeds to step S26, and the operation of ejecting the cleaning water from the nozzle cleaning port 60 is stopped based on closing the on-off valve solenoid 33. To do.

  When the CPU 11 closes the on-off valve solenoid 33 in step S26, the CPU 11 determines whether or not there is a human signal from the human sensor 21 in step S27. For example, when the user lifts the buttocks from the toilet seat 16 after operating the stop switch 6 and moves out of the detection area of the human sensor 21, the CPU 11 uses the human sensor 21 based on the absence of the human sensor signal in step S27. In step S28, the timer T is reset to "0", and in step S29, the presence or absence of a clock signal is determined. When it is determined that there is a clock signal, the process proceeds to step S30, and a unit value is added to the timer T.

  When adding the timer T in step S30, the CPU 11 compares the addition result of the timer T with a toilet cleaning start time (for example, 10 seconds) recorded in advance in the ROM 12 in step S31. The toilet cleaning start time is such that after the user finishes excretion, the lever of the low tank 22 is operated, and the cleaning water for discharging the excrement is injected from the low tank 22 into the toilet 1. When the CPU 11 determines that the addition result of the timer T has reached the toilet cleaning start time in step S31, the CPU 11 proceeds to step S32 and moves the nozzle motor 54 in the forward direction by the maximum amount. Based on the driving, each of the bottom nozzle 49 and the bidet nozzle 51 is moved from the retracted position to the advanced position. In step S33, the bidet cleaning output port of the flow rate adjusting valve 56 is selectively opened based on the rotational operation of the switching valve motor 61. In step S34, the on-off valve solenoid 33 is opened. In the open state of the on-off valve solenoid 33, warmed wash water containing antibacterial components spouts from the bidet wash port 52 and the toilet flush port 53, respectively, and the toilet 1 is warmed to contain antibacterial components. Wash water is sprayed. This step S34 corresponds to toilet bowl cleaning processing means.

  When the CPU 11 opens the on-off valve solenoid 33 in step S34, the counter N is reset to “0” in step S35, and the nozzle motor 54 is rotated in the reverse direction by a predetermined intermediate amount in the ROM 52 in step S36. This intermediate amount is a value for moving each of the butt nozzle 49 and the bidet nozzle 51 from the forward position to the toilet cleaning limit position, and the toilet cleaning limit position is set behind the forward position and ahead of the backward position. Has been.

  When the CPU 11 moves each of the buttocks nozzle 49 and the bidet nozzle 51 from the forward position to the toilet cleaning limit position in step S36, the CPU 11 rotates the nozzle motor 54 in the positive direction by an intermediate amount in step S37. Each of the butt nozzle 49 and the bidet nozzle 51 is moved from the toilet cleaning limit position to the forward movement position. Then, the process proceeds to step S38, and the round trip value “1” recorded in advance in the ROM 12 is added to the counter N.

  When the CPU 11 adds “1” to the counter N in step S38, the addition result of the counter N is compared with the reciprocation limit number (for example, 3) recorded in advance in the ROM 12 in step S39. Here, when “N <reciprocation limit number” is determined, the process returns to step S36, and each of the buttocks nozzle 49 and the bidet nozzle 51 is reciprocated between the forward position and the toilet cleaning limit position. That is, the toilet cleaning port 53 sprays warmed antibacterial cleaning water on the toilet 1 while reciprocating back and forth.

  When the CPU 11 reciprocates the buttocks nozzle 49 and the bidet nozzle 51 by the reciprocation limit number between the forward position and the toilet cleaning limit position, the CPU 11 determines “N = reciprocation limit number” in step S39. Then, the washing water ejection operation is stopped based on closing the on-off valve solenoid 33 in step S40, and the butt nozzle 49 based on rotating the nozzle motor 54 in the reverse direction by the maximum amount in step S41. Each of the bidet nozzles 51 is moved from the forward position to the backward position.

According to the said Example 1, there exists the following effect.
Since the cleaning water having sterilizing properties was jetted from the nozzle cleaning port 60 to the buttocks cleaning port 50 of the buttocks nozzle 49 and the bidet cleaning port 52 of the bidet nozzle 51, a large-capacity silver electrode was used. It is possible to prevent wrinkles from occurring in each of the buttocks nozzle 49 and the bidet nozzle 51 without doing so. Moreover, since the cleaning water having sterilizing properties was ejected from the nozzle cleaning port 60 in a state in which each of the buttocks nozzle 49 and the bidet nozzle 51 was moved to the retracted position, the outer nozzle 46 and the nozzle cover 47 It is possible to sterilize gaps in which the soot easily accumulates. Further, the disinfectant 73 was stored in the same case 2 as the hot water heater 41. For this reason, since the disinfectant 73 comes into contact with the warmed wash water, the solubility of the disinfectant component of the disinfectant 73 in the wash water is increased. Accordingly, since cleaning water containing a high concentration of the sterilizing component is ejected from the nozzle cleaning port 60 to each of the buttocks cleaning port 50 and the bidet cleaning port 52, the buttocks cleaning port 50 and the bidet cleaning port Each of 52 increases the effect of preventing wrinkles.

  The silver ions released from the disinfectant 73 are generally positively charged, and the positively charged silver ions are attracted to the negative charge of the bacteria, and the electrical balance in the bacteria's cells is disrupted and the bacteria are They die and die to react with the -SH group of the enzyme in the bacteria to eliminate activity. When silver ions are released from the phosphate glass of the disinfectant 73, hydroxyl radicals OH · are generated at the same time, and the bacteria are killed by the oxidative activity action.

  In order to release silver ions from the disinfectant, there is a method of impregnating a porous body such as zeolite or apatite containing silver ions and using ion-substituted silver ions. Since this substance elutes silver ions little by little from the surface, the concentration becomes high immediately after the start of use, but porous materials such as zeolite and apatite are not eluted and do not wear out. The elution rate of the fungal component is slow, and as a result, the elution concentration gradually decreases. Unlike the conventional zeolite and apatite containing silver ions, phosphate ions are present, so silver ions are stably present due to the chelating action. For example, each of the ass nozzle 49 and the bidet nozzle 51 It reacts with the resin used in the resin and the inorganic filler contained in the resin to adsorb silver, so that the sterilization effect is further enhanced and the bacteria on the surface after washing with the adsorbed silver ions It can suppress the growth of and maintain the antibacterial action continuously. Since silver ions released from the disinfectant 73 have a binding action to the glassy substance other than the resin and to the —OH group, for example, a glass glaze on the surface of a toilet bowl made of ceramics. It also binds to the components and can impart an antibacterial action in the same manner as the resin surface described above.

  Each through-hole of the buttocks cleaning port 50, each of the through-holes of the bidet cleaning port 52, each of the through-holes of the toilet cleaning port 53, and the nozzle cleaning port 60 is larger than the hole diameter of the mesh 71 of the cassette case 70. It was set larger than the hole diameter of the mesh 72 of the cassette case 70. For this reason, when the disinfectant 73 escapes from the inside of the cassette case 70, the through holes of the butt cleaning port 50, the through holes of the bidet cleaning port 52, the through holes of the toilet cleaning port 53, and the nozzles. Since the sterilizing agent 73 is discharged from each of the cleaning ports 60, the disinfectant 73 passes through the through holes of the butt cleaning port 50, the through holes of the bidet cleaning port 52 and the through holes of the toilet cleaning port 53. It is possible to prevent troubles in the washing water ejection operation based on clogging of any of the nozzle cleaning ports 60.

  When the user operates the stop switch 6, the toilet squirts flush water into the toilet 1 from the toilet flushing port 53 on the basis that the toilet cleaning start time elapses based on the determination that the user is not present. The cleaning process was started. For this reason, after the user finishes excretion, the lever of the low tank 22 is operated, the washing water for discharging the excrement from the low tank 22 into the toilet 1 is injected, and the flow of the washing water disappears in the toilet 1 Accordingly, since the wash water having antibacterial properties is ejected from the toilet flushing port 53 into the toilet 1, the flushing water jetted from the toilet flushing port 53 into the toilet 1 flows by the washing water from the low tank 22. It will not be done. Therefore, it is possible to prevent odor from being generated in the toilet 1.

  In general, a toilet is formed of ceramic as a base material, and a vitreous glaze is applied to the surface of the toilet. Also, when excrement adheres on the surface of this toilet, miscellaneous germs using this as a nutrient source may grow and odor may be generated. The unpleasant odor of the toilet bowl is attributed to numerous urine splashes on the rim of the toilet bowl that attach when a man uses it while standing in front of the toilet bowl. This was announced by Lion Co., Ltd. at the 2005 Japan Society of Home Economics. In this announcement, the number of bacteria in a place where there was a lot of urine jumps one week after the man used it while standing in front of the toilet. It is also included that many occur. The number of bacteria after one week is about “2000 / cm 2” and the causative bacteria are mainly staphylococcus (S. aureus etc.), and strong odor of ammonia is caused by staphylococcus decomposing urine components. appear. When this urine splash dries, the odor becomes stronger. This unpleasant odor is attributed to the presence of sulfur-containing compounds containing elemental sulfur in the structure of dried urine.

  The bidet nozzle 51 was reciprocated between the forward position and the toilet cleaning limit position when the cleaning water was jetted into the toilet 1 from the toilet cleaning port 53 of the bidet nozzle 51. For this reason, since the washing water is ejected from the toilet cleaning port 53 to a wide area in the toilet 1, the sterilization effect of the toilet 1 is enhanced in the wide range of the toilet 1. Warm water-washed cleaning water containing a disinfecting component was ejected from the butt cleaning port 50 of the butt nozzle 49 and the bidet cleaning port 52 of the bidet nozzle 51. For this reason, since a user's washing object part is washed with warm washing water containing a sterilization ingredient, the sterilization effect of the washing object part is also enhanced.

Since the disinfectant 73 is stored in the case 2 for storing the washing water, a dedicated tank for storing the disinfectant 73 becomes unnecessary. In addition, since the entire flow path is not obstructed, the flow rate does not change over time depending on the degree of solubility of the disinfectant 73. Further, the cleaning water in the case 2 is heated in the case 2 between the first use and the next use. For this reason, since the solubility of the disinfectant 73 is increased, the concentration of the disinfecting component of the cleaning water ejected from the nozzle cleaning port 60 can be maintained at a constant high value.
[Example 2]
FIG. 10 shows the processing contents executed by the CPU 10 of the control circuit 10 in place of FIG. 9. The CPU 11 performs the cleaning of the buttocks cleaning port 50 and the bidet nozzle 51 of the buttocks nozzle 49 in step S26 of FIG. When each cleaning operation of the bidet cleaning port 52 is stopped, it is determined in step S42 whether or not the lever switch is turned on. This lever switch is turned on when the user operates the lever. This lever is operably attached to the low tank 22, and when the lever is operated, washing water for flowing excrement into the toilet 1 is released from the low tank.

When the CPU 11 determines that the lever switch is turned on in step S42, the process proceeds to step S28. That is, when the user flows excrement based on operating the lever of the low tank 22, the toilet bowl cleaning start time (in this case, 5 seconds) passes based on the operation of the lever. The cleaning port 53 moves from the retreat position to the advance position, and sprays warmed antibacterial wash water into the toilet 1 while reciprocating between the advance position and the toilet toilet cleaning limit position. For this reason, since the wash water which has antibacterial property comes to be ejected in the toilet bowl 1 from the toilet flush mouth 53 when the flow of the washing water for discharging excrement in the toilet bowl 1 disappears, the toilet bowl 1 It is possible to prevent the generation of odor.
[Example 3]
As shown in FIG. 11, a disinfectant case 81 is detachably interposed in the hose 59, and a mesh 82 corresponding to a filter is joined to the inside of the disinfectant case 81. The mesh 82 corresponds to a filter, and the mesh 82 has a hole diameter of each through hole of the buttocks cleaning port 50, each of the through holes of the bidet cleaning port 53, and each of the through holes of the toilet cleaning port 53. And the nozzle cleaning port 60 are set smaller than each other.

  The internal space of the disinfectant case 81 is partitioned by a mesh 82 into an upper wash water circulation chamber 83 and a lower disinfectant storage chamber 84. A hose 59 is connected to the wash water circulation chamber 83, a disinfectant 73 is accommodated in the disinfectant storage chamber 84, and the on-off valve 31 is in a state where the flow rate adjustment valve 56 is switched to the nozzle cleaning state. When opened, antibacterial cleaning water is discharged from the nozzle cleaning port 60 through the hose 59 and the disinfectant 73 in the disinfectant case 81 in this order, and the flow control valve 56 is switched to the buttocks cleaning state. When the on-off valve 31 is opened, antibacterial cleaning water is not discharged from the buttocks cleaning port 50, and the on-off valve 31 is opened with the flow rate adjusting valve 56 switched to the bidet cleaning state. Antibacterial cleaning water is not discharged from the bidet cleaning port 52 and the toilet cleaning port 53, respectively.

According to the said Example 3, there exist the following effects.
The hot water heater 41 is warmed and the hot water heater 41 is warmed and the disinfectant 73 imparts antibacterial properties. A hose 58 that supplies unwashed cleaning water to the bidet nozzle 51 and a hose 59 that warms the warm water heater 41 and supplies cleaning water to which the antibacterial agent 73 has antibacterial properties are provided. For this reason, since the wash water which has antibacterial property is supplied only to the nozzle cleaning port 60, the usage-amount of the disinfectant 73 can be reduced. Each of the hose 57 and the hose 58 corresponds to a first water supply channel, and the hose 59 corresponds to a second water supply channel.

The inside of the sterilizing agent case 81 is partitioned into an upper cleaning water circulation chamber 83 and a lower sterilizing agent storage chamber 84, and a hose 59 is connected to the cleaning water circulation chamber 83. 73 was stored. For this reason, the flow path of the wash water is not directly passed to the disinfectant 73 stored in the column shape, but only the components dissolved in the flow path are passed to the flow water. Since it comes in, it can suppress that the disinfectant 73 becomes the pressure loss of flowing water. In addition, when the sterilizing agent 73 becomes small, it is possible to prevent pressure loss from occurring due to the mesh 82 being clogged with the sterilizing agent 73, or to change the amount of running water due to the change in the degree of pressure loss. Since the disinfectant case 81 is detachably provided, the disinfectant 73 can be replenished based on replacing the disinfectant case 81 with a new disinfectant case 81.
[Example 4]
As shown in FIG. 12, a disinfectant case 81 is detachably interposed in the hose 55, and when the on-off valve 31 is opened with the flow rate adjusting valve 56 switched to the nozzle cleaning state, the nozzle cleaning is performed. When the antibacterial cleaning water is discharged from the mouth 60 via the disinfectant 73 in the disinfectant case 81 and the on-off valve 31 is opened with the flow rate adjustment valve 56 switched to the buttocks cleaning state. Antibacterial cleaning water was discharged from the butt cleaning port 50 via the disinfectant 73 in the disinfectant case 81, and the on-off valve 31 was opened with the flow rate adjustment valve 56 switched to the bidet cleaning state. Occasionally, antibacterial cleaning water is discharged from the bidet cleaning port 52 and the toilet cleaning port 53 via the disinfectant 73 in the disinfectant case 81.

According to the said Example 4, there exists the following effect.
A disinfectant case 81 was connected to the downstream side of the case 2 immediately after the case 2. For this reason, since the washing water flows into the sterilizing agent case 81 after being heated by the hot water heater 41, the sterilizing component is easily dissolved from the sterilizing agent 73.

In each of the above Examples 3 to 4, the inside of the disinfectant case 81 is configured to be visually recognizable from the outside by providing a transparent part in a part or all of the disinfectant case 81, The usage status of the disinfectant 73 in the fungus case 81 may be confirmed from the outside. In the case of this configuration, it is preferable to enhance the visual recognizability of the disinfectant 73 by coloring the phosphate glass with a metal such as cobalt or iron.
[Example 5]
A heating unit 90 is connected to the downstream side of the valve mechanism 24 via a hose 23 as shown in FIG. The heating unit 90 is formed by winding a heater wire around the outer peripheral surface of a metal heating tube, and is heated based on the fact that the on-off valve 31 is opened when the bottom switch 4 or the bidet switch 5 is operated. Tap water flows through the pipe, and the heater wire heats the tap water by heating the tap water in the heating pipe. A flow rate adjusting valve 56 is connected to the heating unit 90 via a hose 55. A disinfectant case 81 is detachably interposed in the hose 55, and in a state where the flow rate adjusting valve 56 is switched to the nozzle cleaning state, antibacterial cleaning water is discharged from the nozzle cleaning port 60, and the flow rate adjusting valve is discharged. Antibacterial cleaning water is discharged from the buttocks cleaning port 50 when 56 is switched to the buttocks cleaning state, and when the flow control valve 56 is switched to the bidet cleaning state, the bidet cleaning port 52 and the toilet bowl are used. Antibacterial cleaning water is discharged from each of the cleaning ports 53.

According to the said Example 5, there exist the following effects.
A disinfectant case 81 was connected to the downstream side of the heating unit 90 immediately after the heating unit 90. For this reason, since the washing water flows into the sterilizing agent case 81 after being heated by the heating unit 90, the sterilizing component is easily dissolved from the sterilizing agent 73.

  In each of the first to fifth embodiments, the nozzle cleaning switch is attached to each of the control panel 3 and the remote controller 15, and the nozzle cleaning switch of the control panel 3 or the nozzle cleaning switch of the remote controller 15 is operated. It is good also as a structure which performs a nozzle cleaning course. This nozzle cleaning course is a warmed cleaning having antibacterial properties from the nozzle cleaning port 60 to the buttocks cleaning port 50 and the bidet cleaning port 51 in the retracted state of the buttocks nozzle 49 and the bidet nozzle 51, respectively. It is the content which spouts water.

  In each of the above-mentioned Examples 1 to 5, the sterilized glass expanded in a cubic shape or a plate shape is crushed, and a certain size or larger is stored in the cassette case 70 or the sterilizing agent case 81.
