"".

FIG. 2 is a block diagram showing a main configuration of the sanitary washing device according to the present embodiment.
FIG. 2 also shows the main configuration of the water channel system and the electrical system.

  The sanitary washing device 100 according to this embodiment includes a flow path (pipe) 401 that guides water supplied from a water supply source such as a water supply or a water storage tank to the water discharge port 474 of the washing nozzle 473. An electromagnetic valve 431 is provided on the upstream side of the flow path 401. The electromagnetic valve 431 is an electromagnetic valve that can be opened and closed, and controls the supply of water based on a command from the control unit 410 provided in the casing 400.

  A heat exchanger unit 440 is provided downstream of the electromagnetic valve 431. The heat exchanger unit 440 has a hot water heater (not shown). The hot water heater heats the supplied water to obtain predetermined hot water. The hot water temperature can be set, for example, by the user operating an operation unit (not shown) such as a remote controller.

  An electrolytic cell unit 450 capable of generating sterilizing water (functional water) is provided downstream of the heat exchanger unit 440. The sterilizing water generated in the electrolytic cell unit 450 is sprayed from the water outlet 474 of the cleaning nozzle 473 or is sprayed toward the water outlet 474 of the cleaning nozzle 473 and the outer peripheral surface (body). Thereby, the flow path downstream from the electrolytic cell unit 450, the portion of the water discharge port 474 of the cleaning nozzle 473, and the outer peripheral surface are sterilized with sterilizing water.

The electrolytic cell unit 450 has an anode plate (not shown) and a cathode plate (not shown) inside, and can electrolyze the tap water flowing through the inside by the control of energization from the control unit 410. Here, tap water contains chloride ions. This chloride ion is contained as a salt (NaCl), calcium chloride (CaCl ₂ ) or the like in a water source (for example, groundwater, dam water, river water, etc.). Therefore, hypochlorous acid is produced by electrolyzing the chloride ions. As a result, the water electrolyzed in the electrolytic cell unit 450 (electrolyzed water) changes to a liquid containing hypochlorous acid.

Hypochlorous acid functions as a sterilizing component, and the liquid containing hypochlorous acid, that is, sterilizing water, can efficiently remove or decompose or sterilize dirt due to ammonia or oil.
The sterilizing water (electrolyzed water) generated in the electrolytic cell unit 450 may be a liquid containing metal ions such as silver ions and copper ions. Alternatively, the sterilizing water generated in the electrolytic cell unit 450 may be a liquid containing electrolytic chlorine, ozone, or the like. Alternatively, the sterilizing water generated in the electrolytic cell unit 450 may be acidic water or alkaline water. Alternatively, the sterilizing water may be sterilizing water generated by dissolving a sterilizing agent and a sterilizing liquid in water. That is, the apparatus for generating sterilizing water is not limited to the electrolytic cell unit 450.

  A flow path switching valve 460 is provided downstream of the electrolytic cell unit 450. The flow path switching valve 460 includes a vacuum breaker (atmospheric release port) 461 and a flow rate adjustment valve 463. The vacuum breaker 461 is disposed in the middle of the flow path for guiding the water or sterilized water supplied from the electrolytic cell unit 450 to the water outlet 474 of the cleaning nozzle 473, and prevents the water or sterilized water from flowing backward. Alternatively, the vacuum breaker 461 promotes water drainage in the flow path 401 by taking in air.

  A flow rate adjustment valve 463 is provided downstream of the vacuum breaker 461 (atmosphere release side). The flow rate adjusting valve 463 is connected to a flow path that guides the cleaning water to the water outlet 474 for washing the butt, a flow path that guides the cleaning water to the water outlet for the bidet cleaning, and a flow path that guides the cleaning water to the nozzle cleaning chamber 478. Open / close and switch water supply. That is, the flow rate adjustment valve 463 has a plurality of ports that can selectively communicate with the plurality of water discharge ports 474.

A cleaning nozzle 473 is provided downstream of the flow rate adjustment valve 463. The cleaning nozzle 473 receives driving force from the nozzle motor 476 and can advance from the inside of the casing 400 into the bowl 801 of the toilet bowl 800 or retract into the casing 400. That is, the nozzle motor 476 can advance and retract the cleaning nozzle 473 based on a command from the control unit 410.
The flow rate adjustment valve 463 moves as the cleaning nozzle 473 moves back and forth. That is, the flow rate adjustment valve 463 moves together with the cleaning nozzle 473.

  A nozzle cleaning chamber 478 is provided downstream of the flow rate adjustment valve 463. The nozzle cleaning chamber 478 is fixed to the inside of the casing 400 and can wash the cleaning nozzle 473 in a standby state that is retracted into the casing 400. Alternatively, the nozzle cleaning chamber 478 can clean the outer peripheral surface of the cleaning nozzle 473 that is moving forward and backward. Specifically, the nozzle cleaning chamber 478 can sterilize or clean the outer peripheral surface of the cleaning nozzle 473 by injecting sterilizing water or water from a water discharge unit (not shown) provided therein.

FIG. 3 is a schematic plan view showing the inside of the casing of the present embodiment.
FIG. 4 is a schematic perspective view showing the inside of the casing of the present embodiment.
FIG. 3A is a schematic plan view of the state in which the cleaning nozzle 473 has advanced into the bowl 801 as viewed from above. FIG. 3B is a schematic plan view of the state in which the cleaning nozzle 473 is omitted as viewed from above.

  The vacuum breaker 461 promotes a water draining operation for discharging the remaining water in the flow path downstream of the vacuum breaker 461 into the bowl 801 of the toilet bowl 800 through the water discharge port 474 of the cleaning nozzle 473, for example, by taking in air. . However, when the vacuum breaker 461 takes in air, the water downstream of the vacuum breaker 461 may flow backward and flow into the casing 400.

  Further, the flow rate adjustment valve 463 opens / closes and switches water supply to a plurality of flow paths, and can selectively communicate with the plurality of water discharge ports 474. However, for example, when the flow rate adjustment valve 463 switches the selection of the communication destination, water may come out of the flow rate adjustment valve 463.

  As described above with reference to FIG. 1, various functional units such as a body washing functional unit are incorporated in the casing 400. Therefore, if the water that has come out of at least one of the vacuum breaker 461 and the flow rate adjustment valve 463 flows into the casing 400, the sanitary washing device 100 may break down.

  In contrast, as illustrated in FIG. 3B and FIG. 4, the sanitary washing device 100 according to the present embodiment includes a drainage path 480. The drainage channel 480 is formed in the lower plate of the casing 400 and includes a first drainage channel 481 and a second drainage channel 482. As indicated by the arrow A1 shown in FIG. 3B and the arrow A3 shown in FIG. 4, the water leaking from the vacuum breaker 461 passes through the first drainage channel 481 and is discharged out of the casing 400. As indicated by an arrow A <b> 2 shown in FIG. 3B, the water leaking from the flow rate adjustment valve 463 passes through the second drainage channel 482 and is discharged out of the casing 400. Specifically, water leaking from each of the vacuum breaker 461 and the flow rate adjustment valve 463 is discharged into the bowl 801 of the toilet bowl 800.

  According to this embodiment, even when the vacuum breaker 461 takes in air and the water downstream of the vacuum breaker 461 flows backward, the water is reliably discharged out of the casing 400 through the drainage path 480. Further, even if water leaks from the flow rate adjustment valve 463, the water is reliably discharged out of the casing 400 through the drainage path 480. As a result, freezing of the flow path 401 can be prevented, and water can be prevented from leaking inside the casing 400 or from being discharged into the casing 400.

The state in which the sanitary washing device 100a according to this embodiment is attached to the toilet device is the same as the state of the toilet device described above with reference to FIG.
The sanitary washing device 100a according to the present embodiment includes a first flow path (pipe) 403 that guides water supplied from a water supply source such as a water supply or a water storage tank to the water discharge port 474 of the washing nozzle 473. An electromagnetic valve (valve) 431 is provided on the upstream side of the flow path 403. A heat exchanger unit 440 is provided on the downstream side of the electromagnetic valve 431 via a sub tank 433 and a pump 435. The pump 435 can pulsate the flow of water in the flow path 401 and can pulsate the water discharged from the water outlet 474 of the cleaning nozzle 473. Note that the pump 435 is not necessarily provided.

  A vacuum breaker (VB) 461 is provided on the downstream side of the heat exchanger unit 440 via an auto clean 451. A flow rate adjustment valve 463 is provided on the downstream side of the vacuum breaker 461. The water that has passed through the vacuum breaker 461 is guided to the cleaning nozzle 473 via the flow rate adjustment valve 463. The vacuum breaker (VB) 461, the flow rate adjustment valve 463, and the cleaning nozzle 473 are as described above with reference to FIG.

  The flow rate adjustment valve 463 performs opening / closing and switching of water supply to the cleaning nozzle 473 and the toilet spray nozzle 475. The first flow path 403 is divided into a flow path (first flow path 403) that guides water to the cleaning nozzle 473 and a second flow path 405 that guides water to the toilet spray nozzle 475 by the flow rate adjustment valve 463. Branch off.

  In the middle of the second flow path 405, a metal ion acidic water generator 500 is provided. The metal ion acidic water generator 500 generates acidic water containing metal ions. Below, the case where the metal ion acidic water production | generation apparatus 500 produces | generates the acidic water (aluminum ion acidic water) containing an aluminum ion is mentioned as an example, and is demonstrated. In the present embodiment, the case where the metal is aluminum is taken as an example, but the same effect can be exhibited even when iron, copper, aluminum, or the like is used as the metal.

  As shown in FIGS. 5 to 7, the metal ion acidic water generator 500 includes an electrolytic bath 510, a first flow path switching valve 520, a second flow path switching valve 530, an aluminum tank 540, Have The electrolytic bath 510 is provided on the upstream side of the second flow path 405. A first flow path switching valve 520 and a second flow path switching valve 530 are provided on the downstream side of the electrolytic bath 510.

  In the present embodiment, one of the first flow path switching valve 520 and the second flow path switching valve 530 directly discharges alkaline water supplied from the electrolytic bath 510 to the drain pipe of the toilet bowl 800. According to this, alkaline water does not contact the surface of the bowl 801 of the toilet bowl 800. Therefore, it can suppress that alkaline water reduces the bactericidal action of the acidic water sprayed on the surface of the bowl 801.

  Either one of the first flow path switching valve 520 and the second flow path switching valve 530 guides the acidic water supplied from the electrolytic bath 510 to the aluminum bath 540. The aluminum tank 540 includes a tank 541 (see FIG. 9B) and an aluminum 543 (see FIG. 9B). Acidic water supplied from the electrolytic cell 510 is stored in the tank 541. Then, the aluminum 543 installed in the tank 541 is immersed in the acid water stored in the tank 541.

Then, the aluminum 543 immersed in the acidic water dissolves (slow dissolution) over a predetermined time. Thereby, the acidic water in the tank 541 becomes acidic water containing aluminum ions (aluminum ion acidic water). That is, in the aluminum tank 540, an aqueous solution having high acidity containing metal ions (Al ^{3+ in} this embodiment) is generated.

  The aluminum ion acidic water generated by the aluminum tank 540 is guided to the toilet spray nozzle 475. The toilet spray nozzle 475 is provided in the casing 400, for example. The toilet spray nozzle 475 may be provided inside the casing 400 or may be attached outside the casing 400. The toilet spray nozzle 475 sprays the aluminum ion acidic water supplied from the aluminum tank 540 onto the surface of the bowl 801.

  As will be described in detail later, each of the first flow path switching valve 520 and the second flow path switching valve 530 has a plurality of ports that can select either communication or non-communication with the toilet spray nozzle 475. Have Each of the first flow path switching valve 520 and the second flow path switching valve 530 has an air release port 523a (see FIGS. 13A to 13D) communicating with the atmosphere. For example, as indicated by an arrow A14 shown in FIG. 8, each of the first flow path switching valve 520 and the second flow path switching valve 530 selects the atmosphere release port 523a and communicates with the atmosphere, thereby The draining operation for discharging the remaining water in the flow path downstream of the flow path switching valve 520 and the second flow path switching valve 530 (for example, in the aluminum tank 540) is promoted.

Here, for convenience of explanation, the first flow path switching valve 520 of the first flow path switching valve 520 and the second flow path switching valve 530 will be described as an example.
When the first flow path switching valve 520 selects the atmosphere release port 523 a and communicates with the atmosphere, water downstream of the first flow path switching valve 520 may flow backward and flow into the casing 400. The same applies to the second flow path switching valve 530.

In addition, as described above, the first flow path switching valve 520 discharges alkaline water directly to the drain pipe of the toilet bowl 800 or guides acidic water to the aluminum tank 540. However, when the first flow path switching valve 520 switches the supply destination of water (including alkaline water and acidic water), the water may come out of the first flow path switching valve 520. The same applies to the second flow path switching valve 530.
Then, as described above with reference to FIGS. 3 and 4, the sanitary washing device 100 may break down.

  In contrast, as illustrated in FIG. 6, the sanitary washing device 100 a according to the present embodiment includes a drainage path 551. As illustrated in FIG. 7, the sanitary washing device 100 a according to the present embodiment may further include another drainage path 553 different from the drainage path 551. In this case, the other drainage path 553 is connected to the downstream side of the drainage path 551.

  As shown by the arrow A11 shown in FIG. 6A and the arrow A12 shown in FIG. 6B, the water leaking from the first flow path switching valve 520 passes through the drainage path 551 and is outside the casing 400. To be discharged. Alternatively, as shown by an arrow A <b> 13 illustrated in FIG. 7, the water leaking from the first flow path switching valve 520 passes through the drainage paths 551 and 553 and is discharged out of the casing 400. Specifically, the water leaking from the first flow path switching valve 520 is discharged into the bowl 801 of the toilet bowl 800. The same applies to water leaking from the second flow path switching valve 530. In addition, the installation water and installation form of a drainage path are not necessarily limited to the installation water and installation form of the drainage path 551,553 shown to FIG. 6 and FIG.

  According to this, even if the first flow path switching valve 520 selects the atmosphere release port and communicates with the atmosphere, and the water downstream of the first flow path switching valve 520 flows backward, the water is drained. It is reliably discharged out of the casing 400 through the paths 551 and 553. Even if water leaks from the first flow path switching valve 520, the water is reliably discharged out of the casing 400 through the drainage paths 551 and 553. As a result, the first flow path 403 and the second flow path 405 can be prevented from freezing, and water can be prevented from leaking inside the casing 400 or from being discharged into the casing 400. be able to. The same applies to the second flow path switching valve 530.

In addition, the electrolytic cell 510 includes a first electrode plate 514 and a second electrode plate 515 therein, and the first electrode plate 514 and the second electrode plate are controlled by controlling energization from the control unit 410. The tap water flowing in the space (flow path) between 515 and 515 can be electrolyzed. At this time, acid (H ⁺ ) is consumed in the cathode plate (for example, the second electrode plate 515), and the pH rises in the vicinity of the cathode plate. That is, alkaline water is generated in the vicinity of the cathode plate. On the other hand, alkali (OH ⁻ ) is consumed in the anode plate (for example, the first electrode plate 514), and the pH is lowered in the vicinity of the anode plate. That is, acidic water is generated in the vicinity of the anode plate.

Therefore, alkaline water is discharged as “OUT2”.

Subsequently, when polarity inversion is performed, the first electrode plate 514 becomes a cathode plate and the second electrode plate 515 becomes an anode plate. In that case, the acidic water generated in the vicinity of the second electrode plate 515 is supplied to the second flow path switching valve 530. At this time, the second flow path switching valve 530 selects the acidic water port 523b so that the acidic water flows to the acidic water flow path 504 (see FIG. 13B). Therefore, acidic water is discharged as “OUT1”.
On the other hand, the alkaline water generated in the vicinity of the first electrode plate 514 is supplied to the first flow path switching valve 520. At this time, the first flow path switching valve 520 selects the alkaline water port 523c so that the alkaline water flows to the alkaline water flow path 503 (see FIG. 13A). Therefore, alkaline water is discharged as “OUT2”.
