As described above, the sanitary washing device 1 according to the present embodiment includes the second pipe 22 and the third pipe 24 supplied from the toilet sanitizer discharge port 30 of the sanitizer nozzle 6 toward the toilet 5. And the fourth pipe 26, the water source W and the buttocks washing nozzle 3 are communicated, and the water supplied from the first pipe 20 connected to the water source W is heated by the hot water generator 25. A passage for supplying the warm water to the butt washing nozzle 3, that is, a washing passage 34 is provided. Furthermore, the sanitary washing device 1 of the present embodiment has a fifth pipe 27 and a sixth pipe 28, and communicates the water source W and the sterilization nozzle 6 and is connected to the water source W.

The other end opening of the sterilization passage 35, that is, the other end opening of the sixth pipe 28 is communicated with the sterilization nozzle 6.

  Next, explanation will be given on the adjustment of the amount of the sterilizing component supplied to at least one of the buttocks washing nozzle 3 and the toilet 5. As described above, the sterilizing solution generator 4 in FIG. 4 brings the sterilizing agent into water by bringing the sterilizing agent disposed in the case 32 into contact with the water supplied from the water supply port 31 into the case 32. Dissolve in. Thereby, the disinfection component melt | dissolved from the disinfection agent is contained in water, and a disinfection liquid is produced | generated. At this time, depending on the temperature of the water in contact with the disinfectant, the speed at which the disinfectant dissolves in water (hereinafter referred to as dissolution rate) and the limit amount of the disinfecting component dissolved in water (hereinafter referred to as solubility). Is different. The disinfectant of the present embodiment elutes silver ions as a disinfecting component. The higher the temperature of the contacted water, the faster the dissolution rate (easy to dissolve), and the lower the temperature of the contacted water, the dissolution rate. Is slow (hard to dissolve). Furthermore, this disinfectant increases the solubility of silver ions, which are disinfecting components that dissolve in water, as the temperature of the contacted water increases, and the solubility of silver ions that dissolve in water decreases as the temperature of the contacted water decreases. Has the property of lowering.

  Therefore, even if the amount of the sterilizing liquid supplied to the buttocks cleaning nozzle 3 and the toilet bowl 5 is the same amount, depending on the temperature of the water in the sterilizing liquid generating apparatus 4, The amount of the sterilization component contained in the supplied sterilization solution is different.

  The temperature of water in contact with the disinfectant disposed in the case 32 of the disinfectant generating device 4 will be described. The temperature of the water in contact with the disinfectant is substantially the same as the temperature in the main body 7 where the case 32 is disposed. The temperature in the main body 7 is the ambient temperature of the sanitary washing device 1 having the main body 7. In this embodiment, the temperature around the seating surface 16 of the toilet seat 2 in FIG. The ambient temperature is defined as the ambient temperature To of the seating surface), and the ambient temperature To of the seating surface is substantially the same as the room temperature in the room where the sanitary washing device 1 is disposed. Therefore, the temperature of the water in contact with the disinfectant is the room temperature in the room where the sanitary washing device 1 is disposed. Therefore, the higher the room temperature, the easier the disinfectant dissolves in water, and the amount of silver ions that are disinfecting components contained in water increases. On the other hand, the lower the room temperature, the more difficult the disinfectant dissolves in water, and the amount of silver ions contained in water decreases.

  Below, the acquisition method of the temperature information which concerns on ambient temperature To (henceforth room temperature) of the seating surface of the toilet seat 2 by the control apparatus 8 is demonstrated. In the present embodiment, the temperature information related to the ambient temperature To of the seating surface of the toilet seat 2 is calculated by the control device 8 as the heat dissipation amount, which is the amount of heat radiated from the seating surface 16 in the toilet seat 2 heated by the toilet seat heater 14. Obtained at. Note that this temperature information acquisition method is known, for example, from Japanese Patent No. 5754193, and detailed description thereof is omitted.

The heat radiation amount Q (heat radiation amount) radiated from the seating surface 16 of the toilet seat 2 varies depending on the ambient temperature To of the seating surface. Here, the heat dissipation amount Q decreases as the ambient temperature To of the seating surface increases, and the heat dissipation amount Q increases as the room temperature decreases. In this embodiment, in order to simplify the calculation of the heat dissipation amount Q, as shown in FIG. 2, the ambient temperature To of the seating surface, the temperature Ts of the seating surface, and the back surface temperature Tb of the back surface 17 of the seating surface 16 The temperature difference (Tb−Ts) between the back surface temperature Tb of the back surface 17 of the toilet seat 2 and the seating surface temperature Ts is defined as a heat dissipation amount Q (a heat dissipation amount Q = Tb−Ts). The relationship between the ambient temperature To of the seating surface and the heat radiation amount Q between the seating surface temperature Ts is a linear proportional relationship as shown in FIG. The heat dissipation amount Q in the present embodiment decreases from Q ₀ to Q ₄₀ when the ambient temperature To of the seating surface increases from 0 ° C. to 40 ° C. The correlation between the ambient temperature To of the seating surface and the heat release amount Q is calculated in advance by a preliminary experiment, and the result calculated in this preliminary experiment is stored in the control device 8 as a heat release amount map.

  As described above, since the heat radiation amount Q from the seating surface 16 varies depending on the ambient temperature To of the seating surface, the heat radiation amount Q is large when the ambient temperature To of the seating surface is low as in winter, so FIG. As shown, the temperature Ts of the seating surface of the toilet seat 2 and the back surface temperature Tb of the back surface 17 of the seating surface 16 are likely to decrease. On the other hand, when the ambient temperature To of the seating surface is high, the temperature drop of the seating surface temperature Ts of the toilet seat 2 and the back surface temperature Tb of the back surface 17 of the seating surface 16 becomes moderate as shown in FIG.

  The toilet seat heater 14 is controlled by a control device. The controller 8 controls the back surface temperature Tb of the back surface 17 of the seating surface 16 to be the desired back surface temperature Tba of the back surface 17 of the seating surface 16. The desired temperature Tba on the back surface takes into account the ambient temperature To of the seating surface. When the control device 8 determines that the back surface temperature Tb of the back surface 17 of the seating surface 16 has decreased from the back surface desired temperature Tba of the back surface 17 of the seating surface 16 to a predetermined temperature, switching is performed so that power is supplied to the toilet seat heater 14. The circuit 18 is controlled to be in an ON state. When the control device 8 determines that the back surface temperature Tb of the back surface 17 of the seating surface 16 has reached the desired back surface temperature Tba of the back surface 17 of the seating surface 16, the control device 8 controls the switching circuit 18 to be in an OFF state to the toilet seat heater 14. Shut off the power supply. At this time, the ON state time is Δt.

As described above, when the ambient temperature To of the seating surface is low as in winter, the temperature Ts of the seating surface of the toilet seat 2 and the back surface temperature Tb of the back surface 17 of the seating surface 16 are likely to decrease, that is, the heat dissipation amount Q increases. The control device 8 performs control so that a large amount of power is supplied from the AC power source 19 to the toilet seat heater 14. In the present embodiment, in order to supply a large amount of power from the AC power source 19 to the toilet seat heater 14, as shown in FIG. 6A, the time during which the switching circuit 18 is in the ON state is lengthened, that is, control is performed. The device 8 performs control so as to shorten the time t _OFF (hereinafter, the off time t _OFF ) in which the switching circuit 18 is in the OFF state. On the other hand, when the ambient temperature To of the seating surface is high, such as in summer, the heat radiation amount Q decreases, so that less power is supplied from the AC power source 19 to the toilet seat heater 14 than when the ambient temperature To is low. Therefore, the control device 8 controls to shorten the time during which the switching circuit 18 is in the ON state, that is, to increase the off time t _OFF during which the switching circuit 18 is in the OFF state.

Therefore, the off time t _OFF in which the switching circuit 18 is in the OFF state within a predetermined time varies depending on the ambient temperature To of the seating surface, and therefore, based on the off time t _{OFF in} which the switching circuit 18 is in the OFF state, Temperature information related to the ambient temperature To of the seating surface can be acquired.

A temperature map showing the correlation between the _OFF time t _OFF when the switching circuit 18 is in the OFF state and the ambient temperature To of the seating surface is calculated in advance in a preliminary experiment and stored in the control device 8. In the preliminary experiment for calculating the temperature map in the present embodiment, the ambient temperature To of the seating surface of the toilet seat 2 is changed from 0 ° C. to 40 ° C. at intervals of 1 ° C., and for each ambient temperature To, a predetermined time t ₀ to t the switching circuit 18 in the same length of time until ₁ calculates the oFF time t _oFF was oFF state, and the ambient temperature of the seating surface and the off-time t _oFF switching circuit 18 is oFF state Is obtained.

  In this way, the control device 8 includes a heat dissipation amount map and a temperature map calculated by a preliminary experiment. The ambient temperature To of the seating surface of the toilet seat 2 is acquired based on the heat dissipation amount Q, which is the amount of heat radiated from the seating surface 16 of the toilet seat 2 heated by the toilet seat heater 14, and based on the ambient temperature of the seating surface, The amount of the sterilizing component supplied to the butt washing nozzle 3 and the toilet 5 is adjusted. In the present embodiment, the control device 8 changes the amount of water supplied to the sterilizing liquid generating device 4 by changing the opening time of the main valve 21, and thereby the sterilizing liquid generating device 4 uses it for butt washing. The amount of the sterilizing solution supplied to the nozzle 3 and the toilet 5 can be changed, that is, the main valve 21 adjusts the amount of the sterilizing component supplied to the buttocks cleaning nozzle 3 and the toilet 5.

  More specifically, when the ambient temperature To of the seating surface is high, the temperature of the water supplied to the sterilization liquid generating device 4 is also high, so that the amount of the sterilization component contained in the generated sterilization liquid is The control device 8 reduces the amount of the sterilization liquid supplied from the sterilization nozzle 6 to the buttocks washing nozzle 3 and the toilet 5 by shortening the opening time of the main valve 21. On the other hand, when the ambient temperature To of the seating surface is low, the temperature of the water is also low and the sterilization component contained in the sterilization solution is small. Therefore, the control device 8 can be removed by increasing the opening time of the main valve 21. The fungus nozzle 6 increases the amount of disinfectant supplied to the buttocks washing nozzle 3 and the toilet 5. In the present embodiment, by changing the supplied amount, the amount of the sterilizing component supplied to the buttocks washing nozzle 3 and the toilet 5 is adjusted to a substantially constant amount regardless of the ambient temperature. This constant amount is an appropriate amount necessary for sterilization of the buttocks washing nozzle 3 and the toilet 5.

  By adopting such a configuration, the amount of the sterilizing component supplied to at least one of the buttocks washing nozzle 3 and the toilet 5 can be adjusted. Therefore, variation in the sterilization effect can be suppressed as compared with the conventional case. Thereby, the cleanliness of the buttocks cleaning nozzle 3 and the toilet 5 can be improved.

  Further, the sanitary washing apparatus 1 adjusts the amount of the sterilizing component supplied to the buttocks washing nozzle 3 and the toilet 5 to a substantially constant amount, so that the buttocks washing nozzle 3 is not affected by the ambient temperature. And toilet 5 can be sterilized. Moreover, by making this fixed amount an appropriate amount necessary for sterilization of the buttocks washing nozzle 3 and the toilet bowl 5, not only the cleanliness of the buttocks washing nozzle 3 and the toilet bowl 5 is improved. Excess consumption of the disinfectant can be suppressed.

  In addition, the sanitary washing device 1 acquires the ambient temperature To of the seating surface as temperature information based on the heat dissipation amount Q that is the amount of heat radiated from the seating surface 16 of the toilet seat 2 heated by the toilet seat heater 14. A temperature detection device 15 that detects the back surface temperature Tb of the back surface 17 of the seating surface only needs to be provided, and a detector such as a temperature sensor for detecting the ambient temperature To of the seating surface becomes unnecessary. Therefore, it is possible to make the sanitary washing device 1 have a simpler configuration and suppress an increase in cost.

  In the above-described embodiment, the sanitary washing device 1 is configured to include the buttocks cleaning nozzle 3 as a cleaning means. However, the present invention is not particularly limited thereto. For example, in addition to the buttocks cleaning nozzle 3 as a cleaning means. In addition, a bidet cleaning nozzle for cleaning a female local area may be provided. In this case, the supply of hot water to the buttocks cleaning nozzle 3 and the bidet cleaning nozzle can be selectively switched by the switching valve.

  Further, when the sanitary washing device 1 includes the bidet washing nozzle as described above, a bidet sanitizing liquid supply port for discharging the sanitizing liquid to the bidet washing nozzle is added to the sanitizing nozzle 6. May be. Alternatively, a sterilization nozzle 6 for discharging a sterilization liquid to the bidet cleaning nozzle may be added. Thereby, the nozzle for bidet washing can be sterilized.

  Moreover, although it is set as the structure by which both the buttocks washing nozzle 3 and the toilet bowl 5 are disinfected by supplying the disinfection liquid from the disinfection nozzle 6, it is not limited to this, For example, it is sufficient if at least one of the buttocks cleaning nozzle 3 and the toilet 5 is sterilized.

  Moreover, although the structure of the water circuit of this embodiment is made into FIG. 3, another structure may be sufficient. For example, although the sterilization liquid production | generation apparatus 4 is set as the structure supplied with water, it is good also as a structure supplied with warm water. With such a configuration, the sterilization nozzle 6 supplies the sterilization solution to the butt washing nozzle 3 and the toilet 5 and the warm water generation device 25 supplies the sterilization solution generation device 4 with the warm water. Disinfecting components are contained in warm water. And the warm water (warm sanitizing liquid) which the sanitizing component contains becomes warm, and the temperature of the warm sanitizing liquid decreases with the passage of time to a temperature substantially equal to room temperature. Considering the difference between the amount of the sterilizing component in the sterilizing solution generated with warm water and the amount of the sterilizing component in the sterilizing solution generated with water, the sterilizing solution is supplied to the butt washing nozzle 3 and the toilet 5. If the amount of the sterilizing solution supplied to the buttocks washing nozzle 3 and the toilet 5 is adjusted so that the amount of the sterilizing component becomes an appropriate amount, the same effect as in the present embodiment can be obtained.

  The timing for supplying the sterilizing solution to the buttocks cleaning nozzle 3 and the toilet 5 may be immediately after the user uses the buttocks cleaning nozzle 3. Further, the operation unit 10 is provided with a sterilization switch for starting and stopping sterilization, and when the user operates the sterilization switch, the sterilization liquid is supplied to the buttocks washing nozzle 3 and the toilet 5. It is good.

  In the present embodiment, the opening / closing time of the main valve 21 is adjusted. However, the timing for supplying the sterilizing liquid to the buttocks washing nozzle 3 and the toilet 5 is set to 4 according to the ambient temperature To of the seating surface. You may adjust every predetermined time interval like every hour or every 8 hours. Moreover, the time interval may be set according to the four seasons. For example, it is preferable to set every 8 hours in spring and autumn, every 4 hours at intervals shorter than spring and autumn in summer, and 12 hours at intervals longer than spring and autumn in winter. According to this, the dispersion | variation in the disinfection effect can be suppressed by suppressing the influence of the temperature by four seasons. At this time, for example, the control device 8 may have a timer function for counting the date and time, and determine the four seasons from the date and time information.

  Moreover, in this embodiment, it was set as the structure which adjusts the quantity of the disinfection component supplied to the nozzle 3 for buttocks washing | cleaning and the toilet bowl 5 by adjusting the opening-and-closing time of the main valve 21, but it is not the main valve 21 and others. A configuration that is adjusted according to the configuration may be used. Thus, it is not limited to adjustment by the opening / closing time of a valve, What is necessary is just to be able to adjust the quantity of the disinfection component supplied to the nozzle 3 for buttocks washing | cleaning and the toilet bowl 5. FIG.

  Further, in the present embodiment, the room temperature is calculated based on the heat radiation amount Q from the seating surface 16 of the toilet seat 2, but it may be configured to include an outside air temperature detecting means such as a sensor for measuring the room temperature. Further, the heat release amount Q is not limited to the calculation method performed in the present embodiment, and may be obtained by other methods or calculation methods.

  Further, the case 32 is transparent, but may be translucent if the disinfectant inside the case 32 can be visually recognized, and may not be transparent or translucent if the internal disinfectant is not required to be visually recognized. Also good. Further, the shape of the case 32 may be another shape.

  Moreover, you may add not only the component mentioned above to the sanitary washing apparatus 1, but a component as needed. For example, a flow rate adjusting device for adjusting the flow rate of hot water ejected from the buttocks cleaning nozzle 3 or the bidet cleaning nozzle may be provided. Further, the sterilization nozzle 6 may be configured integrally with the sterilization liquid generation device 4 or may not include the sterilization liquid generation device 6 and may be directly sterilized from the sterilization liquid generation device 4 to the sterilization target. You may disinfect by supplying liquid. The number of sterilization nozzles 6 is not limited to one, and the sterilization nozzle 6 may be provided for each sterilization target. Moreover, although silver ion was illustrated as a disinfection component, another metal ion etc. may be sufficient as a disinfection component if it has disinfection property.

  As described above, the specific configuration described in the above embodiment is merely an example of the present invention, and the present invention is not limited to such a specific configuration, and departs from the gist of the present invention.
