Description

  Aspects of the present invention generally relate to a toilet device, and specifically to a toilet device capable of sterilizing a bowl portion of the toilet bowl.

  When cleaning the bowl part of the toilet bowl, for example, using the collected water or chemicals collected as sealed water in the bowl, and rubbing the bowl part with a cleaning brush, the dirt attached to the bowl part is removed. ing. Moreover, in order to further improve the cleanliness and hygiene of the bowl portion of the toilet bowl and to sterilize the bowl portion, there are Western-style toilet devices and toilet devices that irradiate ultraviolet rays toward the bowl portion (Patent Documents 1 and 2). Since ultraviolet rays have a bactericidal effect and an effect of suppressing the growth of bacteria, bacteria, fungi, etc., according to the devices described in Patent Documents 1 and 2, sterilization, antifouling and deodorizing of the bowl portion are prevented. It can be carried out.

  However, generally, since water is collected in the bowl portion, ultraviolet rays are difficult to reach or do not reach the portion (draft portion) below the surface of the water (water surface). This is because ultraviolet rays are absorbed by the stored water. Therefore, it becomes difficult to kill bacteria and microorganisms adhering to the draft portion of the bowl portion, and there is a possibility that a sterilizing effect cannot be obtained in the draft portion of the bowl portion.

FIG. 1 is a schematic cross-sectional view illustrating a toilet device according to a first embodiment of the present invention.
In addition, FIG. 1 is a cross-sectional schematic diagram when the toilet device according to the present embodiment is viewed from the front, and the stored water level (reserved water surface) illustrated in FIG. 1A represents a standby state. In addition, the stored water level (reserved water surface) shown in FIG. 1B represents a state lower than that in the standby state.

  A toilet device 10 according to the present embodiment includes a Western-style seated toilet (hereinafter referred to as “toilet body” for convenience of explanation) 100, a toilet seat 200 disposed on the toilet body 100, and a toilet seat 200 in a closed state. And a local cleaning device 400 installed at the upper rear of the toilet main body 100. The toilet seat 200 and the toilet lid 300 are each pivotally supported so as to be openable and closable with respect to the local cleaning device 400, for example.

  The toilet body 100 has a bowl portion 110 therein. Water (reserved water) 120 is stored at the bottom of the bowl portion 110. The stored water 120 is temporarily stored as sealed water in the lower part of the bowl part 110, so that malodors and pests can be prevented from entering the toilet room through a drain pipe or the like. When the toilet lid 300 is closed, the bowl portion 110 is covered with the toilet lid 300 above.

  Moreover, the toilet device 10 concerning this embodiment is provided with the sterilization water spout 20 which makes sterilization water flow to the bowl part 110, or injects. The sterilizing water spout 20 is provided in the upper part of the toilet body 100, for example. However, the installation position of the sterilizing water spout 20 is not limited to this, and may be provided on the lower surface or the front surface of the local cleaning device 400, the central portion of the toilet body 100 in the vertical direction, or the like. In addition, a spreader, a movable nozzle, or the like may be appropriately provided in the sterilizing water spouting port 20 in order to flow or spray the sterilizing water over the entire bowl portion 110.

  Thus, by flowing or spraying the sterilizing water into the bowl part 110, the cleanliness and hygiene of the bowl part 110 of the toilet body 100 can be further improved, and the bowl part 110 can be sterilized. Furthermore, the bowl part 110 can be soiled and deodorized.

  At this time, as described above, the stored water 120 as sealed water is present in the lower portion of the bowl portion 110. Therefore, even if sterilizing water is allowed to flow into the bowl part 110, the sterilizing action or sterilizing effect may be reduced in the portion of the bowl part 110 below the water level (reserved water surface) of the stored water 120. This is because the stored water 120 is water that is appropriately discharged as water (cleaning water) for cleaning the bowl portion 110 and temporarily stored as sealed water, and the concentration of sterilizing water is diluted by the stored water 120. is there. Therefore, there is a possibility that the portion (draft portion) below the stored water level (water surface) during standby cannot be sterilized.

  Therefore, the toilet apparatus 10 according to the present embodiment can lower the water level of the stored water 120 as compared to the standby time when the sterilizing water is flowed into the bowl portion 110 or sprayed. That is, when the bowl part 110 is sterilized, the toilet apparatus 10 can perform the sterilization preparation process which lowers the surface of the stored water 120 and the sterilization process which sterilizes the bowl part 110. The timing and process time for performing the sterilization preparation process and the sterilization process are controlled by, for example, the control unit 410 built in the local cleaning device 400. The control unit 410 is not limited to being built in the local cleaning device 400, and may be built in the toilet main body 100, for example.

Next, the outline | summary of operation | movement of the toilet device 10 concerning this embodiment is demonstrated, referring drawings.
FIG. 2 is a flowchart showing an outline of the operation of the toilet device according to the present embodiment.

  First, when performing a normal operation such as a standby state (step S101), the control unit 410 determines whether or not a condition for sterilizing the bowl unit 110 is applied (step S103). That is, the control unit 410 determines whether or not a command to start execution of sterilization of the bowl unit 110 has been made (step S103).

  Here, the control unit 410 determines that the condition for sterilizing the bowl unit 110 has been applied (step S103: YES). For example, an operation button provided on an operation device such as a remote controller (not shown) by the user Or when an operation button or the like provided on the local cleaning device 400 or the toilet main body 100 is pressed. Alternatively, the timing of the determination is when the local cleaning device 400 is not used, that is, for example, when a human body detection sensor (not shown) appropriately provided in the local cleaning device 400 does not detect a human body in the toilet room. May be. Alternatively, the timing of the determination may be when the toilet device 10 is not used at night or in the daytime. Alternatively, the timing of the determination may be when the bowl part 110 has been washed a set number of times as appropriate.

  Or the control part 410 may memorize | store the usage frequency of the toilet device 10 by a user, and may learn the time slot | zone with the low usage frequency. According to this, the control unit 410 can determine that the conditions for sterilizing the bowl unit 110 have been applied in a time zone where the frequency of use by the user is low, and can sterilize the bowl unit 110.

  Alternatively, the timing of the determination may be, for example, when “auto power saving” which is one of the power saving modes of the heating toilet seat is operating. The “automatic power saving” is a function in which the control unit 410 stores the frequency of use of the toilet device 10 by the user, learns a time period in which the frequency of use is low, and lowers the temperature of the heating toilet seat or the like. According to this, the control unit 410 can determine that the operation of “automatic power saving” is in a time zone where the user is less frequently used, and can sterilize the bowl unit 110.

  Alternatively, the timing of the determination may be, for example, when “timer power saving”, which is one of the power saving modes of the heating toilet seat, is operating. “Timer power saving” is a function in which the control unit 410 automatically lowers the temperature of the heating toilet seat or the like at a time set by the user according to his / her preference. The user generally sets the time in a time zone where the usage frequency is low. According to this, the control unit 410 can determine that the “timer power saving” is in operation is a time zone in which the user is less frequently used, and can sterilize the bowl unit 110.

  When the controller 410 determines that the conditions for sterilizing the bowl 110 have been applied at various timings as described above (step S103: YES), the controller 410 executes a sterilization preparation process for lowering the surface of the stored water than during standby (step S103). S105). In addition, the detail of operation | movement of a sterilization preparation process is mentioned later. Subsequently, the control unit 410 performs a sterilization process of sterilizing the bowl unit 110 by flowing or spraying sterilizing water to the bowl unit 110 (step S107). On the other hand, when determining that the condition for sterilizing the bowl portion 110 is not applied (step S103: NO), the control unit 410 performs a normal operation such as a standby state (step S101).

  Here, as sterilization water used in a sterilization process, the solution containing hypochlorous acid is mentioned, for example. The solution containing hypochlorous acid is generated by electrolyzing tap water and changing chlorine contained in the tap water to hypochlorous acid. This will be described in detail later. Or as sterilization water used in a sterilization process, the water containing metal ions, such as silver ion and copper ion, is mentioned, for example. Alternatively, for example, water containing electrolytic chlorine, ozone, or the like can be given. Alternatively, a solution containing a bactericidal drug can be mentioned. As described above, the sterilizing water used in the sterilizing step is not particularly limited as long as it has sterilizing properties. In the following description, the case where the sterilizing water used in the sterilization process is a solution containing hypochlorous acid will be described as an example.

  According to the operation of the toilet apparatus 10 according to the present embodiment, when the bowl part 110 is sterilized, that is, when sterilizing water is poured or sprayed on the bowl part 110, the control unit 410 stores the stored water 120. A sterilization preparation process is performed to lower the water level than during standby. Therefore, the toilet device 10 according to the present embodiment can suppress the concentration of the sterilized water from being thinner than the stored water 120, and can sterilize the bowl portion 110 below the stored water surface during standby.

Next, a specific example of the operation of the toilet device 10 according to the present embodiment will be described with reference to the drawings.
FIG. 3 is a block diagram illustrating a main configuration of a toilet device according to a specific example of the present embodiment.
FIG. 4 is a schematic cross-sectional view showing the inside of an electrolytic cell for producing a solution containing hypochlorous acid.

First, the main configuration of the toilet device 10 according to a specific example of the present embodiment will be described.
As shown in FIG. 3, a toilet body function unit 30 is installed behind the toilet body 100. Further, the toilet body 100 includes a bowl portion 110 for receiving filth, a drain trap pipe 112 extending from the bottom of the bowl portion 110, a jet water outlet 111 for performing jet water discharge, and a rim water outlet 114 for performing rim water discharge. Is formed.
The jet spout 111 is formed at the bottom of the bowl portion 110 and is disposed substantially horizontally toward the inlet of the drain trap pipe 112 so as to discharge the wash water toward the drain trap pipe 112. ing.
The rim spout 114 is formed at the upper rear of the bowl portion 110 and discharges cleaning water and sterilizing water along the upper edge of the bowl portion 110. That is, the rim spout 114 functions as the sterilizing water spout 20 described with reference to FIG.

  The drain trap pipe 112 has an inlet 112a, a trap ascending pipe 112b that rises from the inlet 112a, and a trap descending pipe 112c that descends from the trap ascending pipe 112b. The top 112d is between the pipe 112c. A drainage pipe 115 is connected to the lower end of the trap descending pipe 112c of the drainage trap pipe 112.

  The toilet device 10 according to the present embodiment is directly connected to a water supply that supplies cleaning water, and the cleaning water is discharged from the rim spout 114 by the water supply pressure. As for jet water discharge, the wash water stored in the water storage tank 51 built in the toilet body function unit 30 is pressurized by the pressure pump 52 and discharged from the jet water discharge port 111 at a large flow rate. .

The toilet body function unit 30 is provided with a water supply channel 41 through which flush water is supplied from the water supply, and the water supply channel 41 is provided with a diaphragm type electromagnetic on-off valve 42 and a water supply channel switching valve 43. In addition, as shown in FIG. 3, the electromagnetic opening / closing valve 42 and the water supply path switching valve 43 are integrally assembled as the valve unit 40.
Further, on the downstream side of the water supply path switching valve 43, a rim side water supply path 44 for supplying cleaning water to the rim spout 114 and a tank side water supply path 45 for supplying cleaning water to the water storage tank 51 are connected. Has been. Here, the water supply path switching valve 43 can supply cleaning water to both the rim-side water supply path 44 and the tank-side water supply path 45 at the same timing, and can arbitrarily set the ratio of the water supply amount to the rim side and the tank side. It is a change-over valve that can be changed.

  A jet-side water supply channel 53 is connected to the lower portion of the water storage tank 51, and a downstream end of the jet-side water supply channel 53 is connected to a jet water outlet 111. A pressurizing pump 52 is provided in the middle of the jet-side water supply channel 53. The pressurizing pump 52 pressurizes the wash water stored in the water storage tank 51 and discharges it from the jet water outlet 111.

  The jet side water supply path 53 includes an upstream jet side water supply path 53a and a downstream jet side water supply path 53b upstream of the pressurizing pump 52. Here, as shown in FIG. 3, the downstream jet side water supply channel 53 b is formed in a convex shape upward, and the top portion 53 c, which is the highest portion of the convex portion, is jetted from the water storage tank 51. It is the highest portion of the jet-side water supply channel 53 that reaches the water outlet 111.

  In the middle of the rim-side water supply channel 44, an electrolytic cell 60 capable of electrolyzing tap water and generating a solution containing hypochlorous acid is provided. Here, the electrolytic cell 60 will be further described with reference to FIG.

  As shown in FIG. 4, the electrolytic cell 60 has an anode plate 61 and a cathode plate 62 therein, and can electrolyze tap water flowing through the inside by controlling the energization from the control unit 410. Here, since tap water contains chlorine, a chlorine ion is produced | generated by the electrochemical reaction of the chlorine, and it changes to the liquid containing hypochlorous acid. Thus, the tap water supplied from the water supply channel switching valve 43 is electrolyzed in the electrolytic bath 60 to become a solution containing hypochlorous acid, and flows out from the rim water spouting port 114 to the bowl portion 110. Hypochlorous acid functions as a sterilizing component, and the solution containing the hypochlorous acid exhibits acidity, and therefore can efficiently remove or decompose dirt due to ammonia or the like.

Water supplied from the water supply path switching valve 43 preferably flows into the lower part of the electrolytic cell 60, and the outlet from the electrolytic cell 60 to the rim water spouting port 114 is preferably provided at the top of the electrolytic cell 60. Thereby, when water of the electrolytic cell 60 flows out, gas such as O ₂ and H ₂ generated by internal electrolysis can be discharged together with the effluent water. Furthermore, it is desirable that a valve such as a vacuum breaker that is opened to the atmosphere when the pressure inside the electrolytic cell 60 rises is provided at the outlet from the electrolytic cell 60 to the rim spout 114. Thereby, O ₂ and H ₂ gas generated by electrolysis can be discharged into the atmosphere even during outflow.

Next, an operation of lowering the water surface from that during standby (operation of the sterilization preparation process) will be described.
When the toilet device 10 of the present specific example lowers the water storage surface from the standby time, first, the standby water supply path switching valve 43 is neutral in communication with both the rim-side water supply path 44 and the tank-side water supply path 45 during standby. Is in position. Next, when the controller 410 determines that the conditions for sterilizing the bowl part 110 have been applied, that is, a command for starting execution of sterilization of the bowl part 110 has been made during this standby time, rim cleaning (pre-rim cleaning) ) Is started.

  First, the control unit 410 switches the water supply path switching valve 43 to the rim side water supply path 44 to a fully open state (rim side fully open position), supplies cleaning water to the rim water outlet 114, and discharges cleaning water from the rim water outlet 114. To do. The bowl 110 is cleaned by the rim water spouting.

  Next, in order to perform jet water spouting (jet cleaning) after a predetermined time (for example, about 25 seconds) has elapsed, the control unit 410 turns on the pressure pump 52 and the pressure pump 52 causes the water storage tank to be turned on. The cleaning water in 51 is supplied to the jet water outlet 111, and the cleaning water is discharged from the jet water outlet 111.

  At this time, first, the control unit 410 holds the pressurizing pump 52 at a relatively low speed (for example, about 1000 rpm), and is in the vicinity of the top 53c of the jet-side water supply channel 53 (that is, above the reservoir surface of the bowl 110). The air remaining in the portion) is slowly discharged from the jet spout 111. As a result, it is possible to prevent the generation of air discharge sound from the jet water outlet 111 that occurs when the pressurization pump 52 is suddenly started at a high speed.

  Further, when the pressurizing pump 52 is turned on, the control unit 410 switches the water supply path switching valve 43 from the rim side fully open position to the tank side fully open position, and performs tank water supply until the upper end float switch 55 is turned on.

  Next, the control unit 410 rotates the pressure pump 52 at a high speed (for example, about 3500 rpm). Thereby, the pressurizing force by the pressurizing pump 52 is increased, and a large amount of washing water is discharged from the jet water outlet 111. This large amount of washing water flows into the inlet 112a of the drain trap pipe 112, a siphon phenomenon is rapidly caused, and the stored water 120 in the bowl 110 is quickly discharged.

  Next, after the siphon action is activated, the control unit 410 changes the rotation speed of the pressurizing pump 52 to a rotation speed (for example, about 3000 rpm) lower than the rotation speed when the siphon is activated. The state at this time is called a “blow region” or the like, and is a region where the wash water in the bowl portion 110 is continuously discharged to the outside through the drain trap pipe 112 by siphon action.

  Next, the control unit 410 stops the operation of the pressurization pump 52 after a predetermined time (for example, about 1.5 seconds) has elapsed since the pressurization pump 52 is rotated at a high speed. When the pressurizing pump 52 is stopped, the washing water in the trap rising pipe 112b of the drain trap pipe 112 returns to the bowl part 110 as return water (water quantity Q1), and due to the inertial force of the rotating part of the pressurizing pump 52. By the rotation, the wash water in the water storage tank 51 is supplied to the bowl portion 110 (water quantity Q2). Due to the amount of water (Q1 + Q2), the stored water 120 at a predetermined water level is accumulated in the bowl portion 110. However, the water surface of the water 120 at this time is lower than the water surface during standby.

Next, when the upper end float switch 55 is turned on by the tank water supply described above, the control unit 410 closes the electromagnetic on-off valve 42 and stops the tank water supply in order to prevent the overflow of the wash water in the water storage tank 51.
Thus, the water level (reserved water surface) of the stored water 120 of the bowl part 110 becomes a lower water level than at the time of standby.

Next, operation | movement of the toilet device 10 of this example is demonstrated, referring drawings.
FIG. 5 is a time chart showing the operation of the toilet device of this example.
First, when the controller 410 determines that the conditions for sterilizing the bowl 110 have been applied, that is, a command to start the sterilization of the bowl 110 has been made, rim water is discharged (time t1 to t2), and then By performing jet water discharge (time t2 to t3), the water level of the stored water 120 is lowered as compared with the standby time. The operation of this sterilization preparation process (time t1 to t3) is as described above with reference to FIG.

  Note that “rim water discharge ON” shown in FIG. 5 means that water is discharged from the rim water discharge port 114, while “rim water discharge OFF” shown in FIG. It means that water is not discharged from the water outlet 114. Further, “jet water discharge ON” shown in FIG. 5 means that water is discharged from the jet water outlet 111, while “jet water discharge OFF” shown in FIG. It means that water is not discharged from the water outlet 111. The same applies to FIG. 6, FIG. 8 to FIG. 10, and FIG.

  Here, when performing rim water discharge (time t1-t2), the control part 410 has not applied the voltage to the anode plate 61 and the cathode plate 62 of the electrolytic cell 60, as represented to FIG. For this reason, the water discharged from the rim water spouting port 114 at this time does not contain hypochlorous acid. That is, the water discharged from the rim spout 114 at this time is not a solution containing hypochlorous acid (sterile water). However, when the rim water is discharged, the controller 410 may apply voltage to the anode plate 61 and the cathode plate 62 of the electrolytic cell 60 to discharge the sterilizing water from the rim water outlet 114. According to this, in this timing, the bowl part 110 more than a stored water surface can be sterilized.

  Subsequently, the control unit 410 applies a voltage to the anode plate 61 and the cathode plate 62 of the electrolytic cell 60 when the stored water surface of the stored water 120 is lowered from the standby time in the sterilization preparation process (time t1 to t3). And the control part 410 performs rim water discharge (time t3-t4). As a result, a solution (sterilizing water) containing hypochlorous acid flows out from the rim spout 114 to the bowl 110. At this time, since the stored water surface is lower than that during standby, sterilizing water can be attached to the bowl portion 110 below the stored water surface during standby.

  And by performing rim water discharge, the condensate water which restores the stored water 120 as sealing water to the stored water surface at the time of standby can be performed with sterilization water (time t3-t4). In this specific example, the case of condensing with sterilized water has been described as an example, but the present invention is not limited to this. For example, 80% of the standby water 120 is reconstituted with sterilized water, and 20% of the standby 120 water is reconstituted with non-sterile water (tap water). Water may be used. About the ratio of the water quantity of sterilization water and the water (tap water) which is not sterilization water, it can change suitably. According to this, even when the electrolyzer 60 cannot generate sterilized water in an amount corresponding to the stored water 120 during standby in a short time, the condensate is completed by replenishing water that is not sterilized water. be able to.

  According to the operation of the toilet apparatus 10 of this specific example, since the sterilizing water can be attached to the bowl portion 110 below the standby water surface, the bowl portion 110 below the standby water surface can be sterilized. . Moreover, the cleanliness and hygiene of the bowl part 110 below the surface of the stored water during standby can be further improved. Furthermore, it is possible to perform antifouling and deodorization of the bowl portion 110 below the surface of the stored water during standby. Therefore, cleaning of the bowl part 110 can be simplified, or the trouble of cleaning the bowl part 110 can be eliminated. Moreover, since the sterilization of the bowl part 110 is not performed wastefully, energy loss can be suppressed or energy saving can be achieved.

  Here, since the condensate stored water 120 has sterilized water, the bowl portion 110 below the surface of the stored water is immersed in the sterilized water even during standby. Therefore, according to the operation of the toilet device 10 of the present specific example, the sterilizing effect of the bowl portion 110 below the water surface can be further sustained. However, after a predetermined time has elapsed after performing condensate with sterilized water, it may be reconstituted with water (tap water) that is not sterilized water. According to this, the dirt removed by the sterilizing water can be discharged to the outside while draining the stored water 120 having the sterilizing water stored in the drain trap pipe 112.

FIG. 6 is a time chart showing a modification of the operation of the toilet device of this example.
In the operation of this modification, the control unit 410 discharges sterilizing water from the rim water discharge port 114 while performing jet water discharge. That is, in the operation described above with reference to FIG. 5, the control unit 410 discharges the sterilizing water from the rim water spouting port 114 substantially simultaneously with or after the end of the jet water discharging (time t3). Rim water discharge (disinfection water discharge) is started during time (time t3).

  More specifically, first, the operation at time t1 to t3 is the same as the operation of the sterilization preparation step (time t1 to t3) described above with reference to FIG. However, the control unit 410 does not end the jet water discharge at time t3. Then, the control unit 410 applies voltage to the anode plate 61 and the cathode plate 62 of the electrolytic bath 60 and discharges sterilizing water from the rim water spouting port 114 (time t3) before terminating jet water spouting.

  According to this, sterilization water can be made to adhere to the lower part (deep part) of the bowl part 110 rather than the case of the operation | movement mentioned above regarding FIG. This is because sterilizing water can be discharged from the rim water discharge port 114 in a state where the water storage surface of the water storage 120 is lowered.

  More specifically, in the case of the operation described above with reference to FIG. 5, the sterilizing water is discharged after the jet water discharge is completed. Is stored with a predetermined amount of water (Q1 + Q2). On the other hand, in the operation of this modified example, since the sterilizing water is spouted while jetting water, when the sterilizing water is spouted, the water in the bowl part 110 is discharged to the outside through the drain trap pipe 112 by siphon action. Yes. Therefore, in the operation of this modification, the sterilizing water can be attached to the lower part (deep part) of the bowl part 110.

  Subsequently, the control unit 410 ends the jet water discharge after a predetermined time from the start of discharging the sterilizing water from the rim water discharge port 114 (time t4). Subsequently, the control unit 410 ends the discharge of the sterilized water from the rim water discharge port 114 after a predetermined time from the end of the jet water discharge (time t5). Thereby, condensate can be performed by the sterilizing water discharged from the rim water spouting port 114. Even in the operation of this modification, it is not necessary to use all the water to be condensed as sterilizing water.

  According to the operation of this modified example, the sterilizing water can be attached to the lower part of the bowl part 110, so that the lower part of the bowl part 110 can be sterilized. Moreover, the cleanliness and hygiene of the lower part of the bowl part 110 can be further improved. Further, with respect to other effects, the same effects as those described above with reference to FIG. 5 can be obtained.

  In the operation of this modification, the drainage pipe 115 and the bowl part 110 may penetrate to discharge the sterilizing water while performing jet water discharge. That is, so-called “out of seal” may occur. Then, malodor may enter the toilet room from the drain pipe 115. Therefore, when performing the operation of the present modification, it is more preferable that the control unit 410 performs an odor scattering prevention process for preventing odors flowing backward from the drain pipe from scattering outside the bowl portion 110.

  For example, it is more preferable that the control unit 410 activates a “deodorizing unit” appropriately installed in the local cleaning device 400. Alternatively, a pressurizer may be appropriately provided in the local cleaning device 400 or the toilet body 100, and pressure (wind pressure) may be applied toward the drain trap pipe 112 or the drain pipe 115 by the pressurizer. Alternatively, a so-called “air curtain” may be appropriately provided in the local cleaning device 400 or the toilet body 100, and the spread of malodor may be suppressed by the “air curtain”. Alternatively, a lid having a structure such as a check valve may be appropriately provided in the drain trap pipe 112 and the drain pipe 115. Alternatively, for example, silver ions may be generated to decompose malodor.

Next, a toilet device 10 according to another specific example of the present embodiment will be described with reference to the drawings.
FIG. 7 is a block diagram showing a main configuration of a toilet device according to another specific example of the present embodiment.

  In the toilet device 10 of the specific example described above with reference to FIG. 3, the electrolytic cell 60 for generating a solution containing hypochlorous acid (sterilizing water) is provided in the middle of the rim-side water supply channel 44. In the toilet device 10, the electrolytic bath 60 is built in the local cleaning device 400. Moreover, in the toilet device 10 of this specific example, the control unit 410 is built in the local cleaning device 400.

  The branch water supply path 33 branched by the branch fitting 31 provided in the water supply path 41 of the toilet body function unit 30 is branched into a nozzle side water supply path 451 and an electrolytic cell side water supply path 452 inside the local cleaning device 400. ing. In the nozzle side water supply channel 451, a constant flow valve 421 that keeps the flow rate of water constant regardless of the supply water pressure, an electromagnetic valve 422 that opens by energization and selectively switches between downstream water flow and water stop, Is provided.

  A heat exchanger 430 is provided downstream of the electromagnetic valve 422. The heat exchanger 430 includes a heater 431 that is a heating source such as a sheathed heater, for example, and stores and heats water supplied through the upstream solenoid valve 422. When water is supplied through the electromagnetic valve 422, heated water is pushed out from the hot water outlet 432 provided at the top of the heat exchanger 430 and flows out.

  A switching valve 441 and a cleaning nozzle 443 are provided downstream of the heat exchanger 430. The water flowing out of the heat exchanger 430 is switched to one of a plurality of water outlets provided in the cleaning nozzle 443 by the switching valve 441. In addition, when only one water discharge port is provided, the switching valve 441 may not be provided. The washing nozzle 443 can wash water such as a “butt” of a user sitting on the toilet seat by spraying water from a water outlet provided at the tip thereof. Note that the user can change the water flow and temperature of water discharged from the cleaning nozzle 443 according to his / her preference, and adjust the heating amount of the heater 431 by a remote controller (not shown).

  On the other hand, the electrolyzer side water supply channel 452 contains a solenoid valve 424 that is opened by energization and selectively switches between water flow / stop water downstream, and a solution containing hypochlorous acid by electrolyzing tap water. An electrolytic cell 60 that can be generated is provided. The structure of the electrolytic cell 60 is similar to the structure described above with reference to FIG. And the water (tap water) supplied through the electromagnetic valve 424 changes into the liquid (sterilization water) containing hypochlorous acid by the electrochemical reaction of chlorine inside the electrolytic bath 60. The sterilizing water generated in the electrolytic bath 60 is guided to the sterilizing water spout 20 (see FIG. 1) or the rim spout 114 provided as appropriate on the lower surface of the local cleaning device 400 through the electrolytic bath-side water supply channel 452. It is poured out into the bowl part 110. About another structure, it is the same as that of the toilet device 10 of the specific example mentioned above regarding FIG. Further, the operation of lowering the water surface from the standby time (operation of the sterilization preparation process) is the same as the operation of the toilet device 10 of the specific example described above with reference to FIG.

Next, operation | movement of the toilet device 10 of this example is demonstrated, referring drawings.
FIG. 8 is a time chart showing the operation of the toilet device of this example.
First, the operation at time t1 to t3 is the same as the operation of the sterilization preparation step (time t1 to t3) described above with reference to FIG. Thereby, the stored water surface of the stored water 120 of the bowl part 110 can be lowered | hung rather than the time of standby. Subsequently, the control unit 410 applies a voltage to the anode plate 61 and the cathode plate 62 of the electrolytic cell 60, opens the electromagnetic valve 424, and discharges sterilizing water to the bowl unit 110 (time t3 to t4). Thereby, the solution (sterilizing water) containing hypochlorous acid is poured out into the bowl part 110.

  In addition, “sterilized water spouting ON” shown in FIG. 8 means that sterilizing water is being spouted from the sterilizing water spout 20 or the rim spout 114, and on the other hand, it is represented in FIG. “Sterilized water spouting OFF” means that the sterilizing water is not discharged from the sterilizing water spout 20 or the rim spout 114. The same applies to FIGS. 9 and 10 described later.

  And when the solution (sterilization water) containing hypochlorous acid is poured out to the bowl part 110, since the water storage surface is lower than at the time of standby, sterilization water is added to the bowl part 110 below the water storage surface at the time of standby. Can be attached. Thereby, the bowl part 110 below the stored water surface at the time of standby can be sterilized. Moreover, condensate can be performed with the sterilizing water discharged to the bowl part 110 (time t3-t4). Also in the operation of this example, as described above with reference to FIG. Further, with respect to other effects, the same effects as those described above with reference to FIG. 5 can be obtained.

FIG. 9 is a time chart showing a modification of the operation of the toilet device of this example.
First, the operation at time t1 to t3 is the same as the operation of the sterilization preparation step (time t1 to t3) described above with reference to FIG. Thereby, the stored water surface of the stored water 120 of the bowl part 110 can be lowered | hung rather than the time of standby. Subsequently, the control unit 410 performs rim water discharge (time t3 to t4). Thereby, the amount of water corresponding to a part of the stored water 120 during standby can be condensed with water (tap water) that is not sterilized water. Subsequently, the control unit 410 applies voltage to the anode plate 61 and the cathode plate 62 of the electrolytic cell 60, opens the electromagnetic valve 424, and discharges sterilizing water to the bowl unit 110 (time t4 to t5). Thereby, the solution (sterilizing water) containing hypochlorous acid is poured out into the bowl part 110.

  Here, when the solution containing hypochlorous acid (sterilizing water) is poured out into the bowl part 110, the surface of the stored water is lower than that during standby. That is, the amount of water corresponding to a part of the stored water 120 at the time of standby is condensed with water (tap water) that is not sterilized water. Lower than the stored water 120. Therefore, the sterilizing water can be attached to the bowl portion 110 below the surface of the stored water during standby. Further, by opening the electromagnetic valve 424 and discharging the sterilized water to the bowl part 110, the amount of water corresponding to the other part of the stored water 120 during standby can be condensed with the sterilized water. That is, the stored water 120 can be restored to the stored water surface during standby by using sterilized water and water (tap water) that is not sterilized water.

  According to this specific example, even when the electrolyzer 60 cannot generate sterilized water having an amount corresponding to the stored water 120 during standby in a shorter time, water that is not sterilized water is supplied to the drain trap pipe 112. Condensation can be completed by replenishing in advance. Further, with respect to other effects, the same effects as those described above with reference to FIG. 5 can be obtained.

FIG. 10 is a time chart showing another modification of the operation of the toilet device of this example.
In the operation of this modification, the control unit 410 discharges sterilizing water to the bowl unit 110 while performing jet water discharge in the same manner as the operation described above with reference to FIG. That is, in the operation described above with reference to FIGS. 8 and 9, the control unit 410 discharges sterilizing water to the bowl unit 110 substantially simultaneously with or after the end of jet water discharge (time t3). In the jet water discharge (time t2 to t4), water discharge of sterilizing water is started (time t3).

  More specifically, first, the operation at time t1 to t3 is the same as the operation of the sterilization preparation step (time t1 to t3) described above with reference to FIG. Thereby, the stored water surface of the stored water 120 of the bowl part 110 can be lowered | hung rather than the time of standby. However, the control unit 410 does not end the jet water discharge at time t3. Then, the controller 410 applies voltage to the anode plate 61 and the cathode plate 62 of the electrolytic cell 60 before ending the jet water discharge, opens the electromagnetic valve 424, and discharges the sterilizing water to the bowl 110 (time t3). ). According to this, as described above with reference to FIG. 6, the sterilizing water can be attached to a lower portion (deep portion) of the bowl portion 110 than in the case of the operation described above with reference to FIGS. 8 and 9.

  Subsequently, the control unit 410 ends the jet water discharge after a predetermined time from the start of the water discharge of the sterilizing water (time t4). Subsequently, the control unit 410 ends the sterilizing water discharge after a predetermined time from the end of the jet water discharging (time t5). Thereby, condensate can be performed with the sterilizing water discharged to the bowl part 110. Even in the operation of this modification, it is not necessary to use all the water to be condensed as sterilizing water.

  In the operation of this modification, the drainage pipe 115 and the bowl part 110 may penetrate to discharge the sterilizing water while performing jet water discharge. That is, so-called “out of seal” may occur. Therefore, as described above with reference to FIG. 6, when performing the operation of this modification, the control unit 410 performs an odor scatter prevention process for preventing the odor that flows backward from the drain pipe from scattering outside the bowl unit 110. More preferably. Further, with respect to other effects, the same effects as those described above with reference to FIG. 5 can be obtained.

Next, a second embodiment of the present invention will be described with reference to the drawings.
FIG. 11: is a cross-sectional schematic diagram showing the toilet device concerning the 2nd Embodiment of this invention.
In addition, FIG. 11 is a cross-sectional schematic diagram when the toilet device according to the present embodiment is viewed from the front, and the stored water level (reserved water surface) shown in FIG. 11A represents a standby state. In addition, the stored water level (reserved water surface) shown in FIG. 11B represents a state that is lower than that during standby.

  The toilet device 10 described above with reference to FIGS. 1 to 10 includes a sterilizing water spout 20 and a rim spout 114 for flowing or spraying sterilizing water to the bowl portion 110. The toilet device 10 according to the present embodiment includes a bowl The unit 110 includes an ultraviolet irradiator 70 that irradiates ultraviolet rays (UV). The ultraviolet irradiator 70 is provided, for example, on the upper part of the toilet body 100. However, the installation position of the ultraviolet irradiator 70 is not limited to this, and may be provided on the lower surface or the front surface of the local cleaning device 400, the vertical central portion of the toilet body 100, and the like. Moreover, as the ultraviolet irradiation body 70, a light emitting diode (LED: Light Emitting Diode), a black light, a chemical light, a mercury lamp, a xenon lamp etc. are mentioned, for example.

  Ultraviolet rays have a bactericidal effect and an effect of suppressing the growth of bacteria, bacteria, molds and the like. Therefore, by irradiating the bowl part 110 with ultraviolet rays from the ultraviolet irradiation body 70, the cleanliness and hygiene of the bowl part 110 of the toilet body 100 can be further improved, and the bowl part 110 can be sterilized. Furthermore, the bowl part 110 can be soiled and deodorized.

  At this time, since the stored water 120 as sealed water exists at the lower part of the bowl part 110, even if the bowl part 110 is irradiated with ultraviolet rays, the portion of the bowl part 110 below the stored water surface of the stored water 120 is sterilized. There exists a possibility that an effect | action or a bactericidal effect may fall. This is because the ultraviolet light irradiated from the ultraviolet irradiation body 70 is absorbed by the stored water 120. Therefore, there is a possibility that the portion (draft portion) below the water storage surface during standby cannot be sterilized.

  Therefore, when the toilet device 10 according to the present embodiment irradiates from the ultraviolet irradiator 70, the water storage surface of the water storage 120 can be lowered as compared with the standby state. That is, when the bowl unit 110 is sterilized similarly to the toilet device 10 described with reference to FIGS. 1 to 10, the toilet device 10 includes a sterilization preparation step for lowering the water surface of the stored water 120, and the bowl unit 110. A sterilization step of sterilization can be performed. The outline of the other structure and operation is the same as the outline of the structure and operation described with reference to FIGS.

Next, operation | movement of the toilet device 10 of this example is demonstrated, referring drawings.
FIG. 12 is a time chart showing the operation of the toilet device of this example.
First, the operation at time t1 to t3 is the same as the operation of the sterilization preparation step (time t1 to t3) described above with reference to FIG. That is, as described above with reference to FIG. 3, the control unit 410 performs rim water discharge, jet water discharge, and the operation of the pressurizing pump 52 to stop the water storage surface of the water 120 stored in the bowl 110. Can be lowered.

  Subsequently, the controller 410 irradiates the bowl 110 with ultraviolet rays from the ultraviolet irradiator 70 (time t3 to t4). Thereby, the bowl part 110 can be sterilized with ultraviolet rays. At this time, since the stored water surface is lower than that during standby, the bowl 110 below the standby water surface during standby can be irradiated with ultraviolet rays from the ultraviolet irradiation body 70.

  Moreover, when the control part 410 irradiates the bowl part 110 with ultraviolet rays from the ultraviolet irradiation body 70, it is more preferable to close the toilet lid 300 by a toilet lid driving device (not shown) that opens and closes the toilet lid 300. According to this, the bowl part 110 can be sterilized using the ultraviolet rays of the frequency band which has higher sterilization property. That is, since the control unit 410 irradiates ultraviolet rays with the toilet lid 300 closed, even if the bowl unit 110 is irradiated with ultraviolet rays having a higher sterilization frequency band, the human body is not adversely affected.

  Subsequently, when the irradiation of the ultraviolet ray is stopped, the control unit 410 performs rim water discharge (time t4 to t5). Thereby, the condensate which restores the stored water 120 as sealing water to the stored water surface at the time of standby can be performed.

  According to the operation of the toilet device 10 of this specific example, since the ultraviolet ray can be radiated to the bowl portion 110 below the pool surface during standby, the bowl portion 110 below the pool surface during standby can be sterilized. Moreover, the cleanliness and hygiene of the bowl part 110 below the surface of the stored water during standby can be further improved. Furthermore, it is possible to perform antifouling and deodorization of the bowl portion 110 below the surface of the stored water during standby.

  In addition, although the case where ultraviolet rays were irradiated after lowering the accumulated water surface of the accumulated water 120 from the standby time was described as an example, the present invention is not limited to this, and the control unit 410 emits ultraviolet rays from the ultraviolet irradiation body 70. However, the surface of the stored water 120 may be lowered. That is, the control unit 410 may start an operation of lowering the stored water surface of the stored water 120 between times t3 and t4 illustrated in FIG. Also by this, it is possible to sterilize by irradiating ultraviolet rays from the ultraviolet irradiating body 70 to the bowl portion 110 below the water surface during standby.

FIG. 13 is a time chart showing a modification of the operation of the toilet device of this example.
In the operation of this modification, the control unit 410 irradiates the ultraviolet rays from the ultraviolet irradiation body 70 while performing jet water discharge. That is, in the operation described above with reference to FIG. 12, the control unit 410 irradiates ultraviolet rays from the ultraviolet irradiation body 70 substantially simultaneously with or after the end of jet water discharge (time t3). Irradiation of ultraviolet rays is started during time (time t2 to t4) (time t3).

  More specifically, first, the operation at time t1 to t3 is the same as the operation of the sterilization preparation step (time t1 to t3) described above with reference to FIG. However, the control unit 410 does not end the jet water discharge at time t3. And the control part 410 starts irradiation of an ultraviolet-ray, before ending jet water spouting (time t3). According to this, it is possible to irradiate ultraviolet rays to a lower part (deep part) of the bowl part 110 than in the case of the operation described above with reference to FIG. Subsequently, the control unit 410 can perform ascites by performing rim water discharge (time t4 to t5).

  According to the operation of this modification, it is possible to sterilize by irradiating the lower part of the bowl part 110 with ultraviolet rays. Moreover, the cleanliness and hygiene of the lower part of the bowl part 110 can be further improved. Further, with respect to other effects, the same effects as those described above with reference to FIG. 12 can be obtained.

  In the operation of the present modification, the drain pipe 115 and the bowl portion 110 may penetrate because ultraviolet rays are emitted while jetting water. That is, so-called “out of seal” may occur. Therefore, as described above with reference to FIG. 6, it is more preferable that the control unit 410 performs an odor scattering prevention process for preventing the odor flowing backward from the drain pipe from being scattered outside the bowl portion 110.

Next, a modified example of the operation of lowering the stored water surface than during standby (operation of the sterilization preparation process) will be described with reference to the drawings.
FIG. 14 is a schematic cross-sectional view for explaining a modified example of the operation for lowering the stored water surface than during standby.

  In the structure and operation of the toilet apparatus 10 described above with reference to FIGS. 3 to 10 and FIGS. 12 to 13, the rim water is discharged, the jet water is discharged, and the operation of the pressurizing pump 52 is stopped. The case where the water surface of the water 120 is lowered from the standby time has been described as an example, but the present invention is not limited to this. For example, as shown in FIG. 14, the water trapping surface of the water pool 120 of the bowl part 110 may be lowered as compared with the standby time by making the drain trap rotatable.

  More specifically, the toilet device shown in FIG. 14 includes a rotating trap portion 140 that is provided in the lower rear portion of the toilet body 100 and secures a certain amount of sealed water (reserved water) 120 in the bowl portion 110. . Inside the local cleaning device 400, a control unit 410, an electromagnetic valve 422, and a detection sensor 461 that detects the uppermost position and the lowermost position of the rotation trap unit 140 are provided. The electromagnetic valve 422 is directly connected to, for example, a water supply, and the stored water 120 can be secured in the bowl portion 110 by opening the electromagnetic valve 422.

  Then, when lowering the stored water level than during standby, first, the control unit 410 drives a motor (not shown) as shown in FIGS. 14 (a) to 14 (b) to turn the trapping unit 140. Is opened downward in the direction of the arrow A1, and the electromagnetic valve 422 is opened. As a result, the accumulated water 120 is discharged from the upper part of the rotating trap part 140 in the direction of the arrow A2. Subsequently, when the capacity of the stored water 120 is reduced by the amount represented by E, the control unit 410 further moves the rotation trap unit 140 to the arrow A4 as illustrated in FIGS. 14B to 14C. The water 120 is discharged in the direction of arrow A3 at once. Thus, the water level (reserved water surface) of the stored water 120 of the bowl part 110 becomes a lower water level than at the time of standby.

  Then, at the same timing as that described above with reference to FIGS. 5 to 6, 8 to 10, and FIGS. 12 to 13, the bowl portion 110 is sprayed with sterilizing water or irradiated with ultraviolet rays, thereby The bowl part 110 below the water surface can be sterilized. The toilet device shown in FIG. 14 may cause a so-called “out of seal”. However, if a lid having a structure such as a check valve is appropriately provided in the rotating trap unit 140, a bad odor is drained. Intrusion into the toilet room from the tube can be suppressed.

  In addition, when condensing the water 120 in the rotating trap unit 140, first, the detection sensor 461 detects the lowest position of the rotating trap unit 140, and discharges sterilized water or ultraviolet rays to the bowl unit 110. A predetermined time elapses after irradiation. Then, the control unit 410 opens the electromagnetic valve 422 while driving a motor (not shown) to rotate the rotation trap unit 140 upward. When the rotation trap unit 140 rotates upward and the detection sensor 461 detects the uppermost position of the rotation trap unit 140, the control unit 410 stops the rotation of the rotation trap unit 140. Thereafter, when the predetermined time elapses and the stored water 120 is secured in the bowl portion 110, the control unit 410 closes the electromagnetic valve 422 and stops water supply from, for example, water supply.

  As described above, according to the present embodiment, when the toilet bowl device 10 sterilizes the bowl part 110, the sterilization preparation process for lowering the surface of the stored water 120 and the sterilization process for sterilizing the bowl part 110. And can be executed. Thereby, sterilizing water can be made to adhere to the bowl part 110 below the surface of the standing water at the time of standby, or an ultraviolet-ray can be irradiated. Therefore, the bowl part 110 below the surface of the stored water during standby can be sterilized. Moreover, the cleanliness and hygiene of the bowl part 110 below the surface of the stored water during standby can be further improved. Furthermore, it is possible to perform antifouling and deodorization of the bowl portion 110 below the surface of the stored water during standby. Therefore, cleaning of the bowl part 110 can be simplified, or the trouble of cleaning the bowl part 110 can be eliminated. Moreover, since the sterilization of the bowl part 110 is not performed wastefully, energy loss can be suppressed or energy saving can be achieved.
