[0003] [Patent Document 1] Patent No. 6686382 Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention has been made based on the recognition of such a problem, and has an object to provide a sanitary washing device that can suppress water dripping. [Means for solving the problem]

[0005] The first invention is a sanitary washing device comprising a casing and a nozzle unit that moves back and forth between the casing and the toilet bowl, the nozzle unit having a washing nozzle with a water outlet that sprays water toward a human body part, and a flow path switching valve that switches between flowing and stopping of water in a flow path that supplies water to the water outlet, and in a stored state in which the washing nozzle is stored, the water outlet is located above the inlet of the flow path switching valve.

[0006] According to this sanitary washing device, when the washing nozzle is stored, the water outlet is positioned higher than the inlet, thereby preventing water from dripping from the water outlet.

[0007] The second invention is a sanitary washing device characterized in that, in the first invention, the flow path has an upwardly convex shape, and in the stored state, the flow path has a top, a first inclined portion that descends as it moves forward from the top, and a second inclined portion that descends as it moves rearward from the top, and the top is located above the water outlet and the inlet in the stored state.

[0008] According to this sanitary washing device, water can be collected in the section of the flow path upstream of the apex, which further prevents water remaining in the washing nozzle from dripping from the water outlet.

[0009] The third invention is a sanitary washing device according to the first or second invention, further comprising a body washing flow path that supplies water to a nozzle washing section that sprays water into the washing nozzle to wash the washing nozzle, the flow path switching valve switching between allowing water to pass through the body washing flow path and stopping the water, and in the stored state, the outlet of the body washing flow path is located above the inlet of the flow path switching valve.

[0010] According to this sanitary washing device, when the washing nozzle is stored, the outlet of the body washing flow path is positioned higher than the inlet, thereby preventing water from dripping from the nozzle washing section.

[0011] The fourth invention is a sanitary washing device characterized in that, in the third invention, it further comprises a water supply flow path that supplies water to the inlet of the flow path switching valve, and the water supply flow path and the body washing flow path are curved with different curvatures and connected to the flow path switching valve.

[0012] According to this sanitary washing device, the curvature of the water supply flow path and the body washing flow path are different from each other, which distributes the timing at which the load is applied to the drive motor that moves the nozzle unit back and forth, thereby suppressing the peak load on the drive motor.

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, like components are designated by like reference numerals and detailed descriptions thereof will be omitted where appropriate. FIG. 1 is a perspective view showing a toilet apparatus equipped with a sanitary washing device according to an embodiment. As shown in Figure 1, a toilet device 300 according to an embodiment includes a sanitary washing device 100 and a Western-style seated toilet bowl (hereinafter, for convenience of explanation, simply referred to as "toilet bowl") 200. The sanitary washing device 100 is provided on top of the toilet bowl 200. The sanitary washing device 100 includes a genital washing device 30 for washing the genitals of a user seated on the toilet seat 20.

[0016] The casing 10 has a case plate 11 and a case cover 12. The case plate 11 forms the bottom of the casing 10. The case plate 11 is placed on the rear of the toilet bowl 200. The case cover 12 is provided on top of the case plate 11 and covers the upper part of the case plate 11. The toilet seat 20 and toilet lid 25 are rotatably supported on the case cover 12.

[0017] The casing 10 houses the private parts cleansing device 30 inside the space surrounded by the case plate 11 and the case cover 12. The casing 10 also houses functional parts such as an opening / closing unit that controls the opening and closing of the toilet seat 20 and the toilet lid 25, a toilet seat heating unit that controls the temperature of the toilet seat 20, and a communication unit that can communicate with the operating unit, etc.

[0018] In this specification, "up," "down," "front," "back," "right," and "left" refer to directions as seen by a user sitting on toilet seat 20 with their back to toilet lid 25, as shown in Figure 1.

[0019] FIG. 2 is a block diagram showing the configuration of the main parts of the sanitary washing device. FIG. 2 shows the main components of the water channel system and electrical system of the sanitary washing device 100. 2, the sanitary washing device 100 has a pipe 110. The pipe 110 extends from a water supply source 500, such as a tap or a water tank, to the nozzle unit 60. The pipe 110 guides water supplied from the water supply source 500 to the nozzle unit 60.

[0020] A solenoid valve 120 is provided upstream of the pipeline 110. The solenoid valve 120 is an openable and closable electromagnetic valve, and controls the supply of water based on commands from a control unit 130 provided inside the casing 10. In other words, the solenoid valve 120 opens and closes the pipeline 110. By opening the solenoid valve 120, water supplied from the water supply source 500 flows into the pipeline 110.

[0021] A pressure regulating valve 121 is provided downstream of the solenoid valve 120. When the water supply pressure is high, the pressure regulating valve 121 adjusts the pressure inside the pipeline 110 to within a predetermined pressure range. A check valve 122 is provided downstream of the pressure regulating valve 121. The check valve 122 prevents water from flowing back upstream of the check valve 122 when, for example, the pressure inside the pipeline 110 drops.

[0022] A heat exchanger unit 123 (heating section) is provided downstream of the check valve 122. The heat exchanger unit 123 has a heater and heats the water supplied from the water supply source 500 to a specified temperature. In other words, the heat exchanger unit 123 generates hot water.

[0023] The heat exchanger unit 123 is an instantaneous heating type (instantaneous type) heat exchanger that uses, for example, a ceramic heater. An instantaneous heating type heat exchanger can heat water to a specified temperature in a shorter time than a hot water storage heating type heat exchanger that uses a hot water storage tank. Note that the heat exchanger unit 123 is not limited to an instantaneous heating type heat exchanger, and may also be a hot water storage heating type heat exchanger. Furthermore, the heating section is not limited to a heat exchanger, and may use other heating methods, such as one that uses microwave heating.

[0024] The heat exchanger unit 123 is connected to the control unit 130. The control unit 130 controls the heat exchanger unit 123 in response to, for example, the operation of the operation unit 140 by the user, thereby raising the temperature of the water to the temperature set by the operation unit 140.

[0025] A flow rate sensor 124 is provided downstream of the heat exchanger unit 123. The flow rate sensor 124 detects the flow rate of water discharged from the heat exchanger unit 123. In other words, the flow rate sensor 124 detects the flow rate of water flowing through the pipe 110. The flow rate sensor 124 is connected to the control unit 130. The flow rate sensor 124 inputs the flow rate detection result to the control unit 130.

[0026] A vacuum breaker (VB) 125 is provided downstream of the flow sensor 124. The vacuum breaker 125 has, for example, a flow path for flowing water, an intake port for taking air into the flow path, and a valve mechanism for opening and closing the intake port. For example, the valve mechanism closes the intake port when water is flowing through the flow path, and opens the intake port when the water flow stops, taking air into the flow path. In other words, the vacuum breaker 125 takes air into the pipeline 110 when there is no water flow in the pipeline 110. For example, a float valve is used as the valve mechanism.

[0027] The vacuum breaker 125 takes in air into the pipeline 110, thereby promoting drainage of water in the portion downstream of the vacuum breaker 125, for example. The vacuum breaker 125 promotes drainage of water from, for example, the nozzle unit 60. In this way, the vacuum breaker 125 drains water from the nozzle unit 60 and takes in air into the nozzle unit 60, thereby preventing, for example, flush water in the nozzle unit 60 from flowing back toward the water supply source 500 (tap water).

[0028] An electrolytic cell unit 126 is provided downstream of the vacuum breaker 125. The electrolytic cell unit 126 generates a liquid containing hypochlorous acid (functional water) from tap water by electrolyzing the tap water flowing therein. The electrolytic cell unit 126 is connected to a control unit 130. The electrolytic cell unit 126 generates functional water under the control of the control unit 130.

[0029] The functional water produced in the electrolytic cell unit 126 may be a solution containing metal ions such as silver ions or copper ions. Alternatively, the functional water produced in the electrolytic cell unit 126 may be a solution containing electrolytic chlorine or ozone. Alternatively, the functional water produced in the electrolytic cell unit 126 may be acidic water or alkaline water.

[0030] A pressure modulation unit 127 is provided downstream of the electrolytic cell unit 126. The pressure modulation unit 127 imparts pulsation or acceleration to the flow of water in the pipeline 110, and imparts pulsation to the water discharged from the water outlet of the cleaning nozzle 85 and the water outlet of the nozzle cleaning unit 44. In other words, the pressure modulation unit 127 varies the flow state of the water flowing in the pipeline 110. The pressure modulation unit 127 is connected to the control unit 130. The pressure modulation unit 127 varies the flow state of the water based on the control of the control unit 130. The pressure modulation unit 127 varies the pressure of the water in the pipeline 110.

[0031] A flow rate adjustment unit 71 and a flow path switching valve 70 (flow path switching device) are provided downstream of the pressure modulation unit 127. The flow rate adjustment unit 71 (flow rate adjustment valve) adjusts the water pressure (flow rate). The flow path switching valve 70 is provided downstream of the flow rate adjustment unit 71. The flow path switching valve 70 is connected to a water supply flow path 79. Water is supplied to the flow path switching valve 70 from the upstream side via the water supply flow path 79.

[0032] The flow path switching valve 70 is a unit that has a flow path switching unit 72. The flow path switching unit 72 opens, closes, or switches the water supply to the nozzle body 80 of the cleaning nozzle 85 and the nozzle cleaning unit 44. The flow rate adjustment unit 71 and the flow path switching unit 72 are connected to the control unit 130. The operation of the flow rate adjustment unit 71 and the flow path switching unit 72 is controlled by the control unit 130.

[0033] A plurality of flow paths (a posterior cleansing flow path 80a, a soft cleansing flow path 80b, a bidet cleansing flow path 80c, a body cleansing flow path 75, and a jetting flow path 76) are connected downstream of the flow path switching valve 70 (flow path switching unit 72). The posterior cleansing flow path 80a, the soft cleansing flow path 80b, and the bidet cleansing flow path 80c are provided inside the nozzle body body. The posterior cleansing flow path 80a, the soft cleansing flow path 80b, and the bidet cleansing flow path 80c are flow paths that supply water to a water outlet that discharges water toward the human private parts. That is, the cleansing nozzle 85 discharges water supplied from the flow path switching unit 72 via the posterior cleansing flow path 80a, the soft cleansing flow path 80b, and the bidet cleansing flow path 80c.

[0034] The body cleaning flow path 75 is a conduit that connects the flow path switching valve 70 and the nozzle cleaning unit 44. The nozzle cleaning unit 44 discharges water supplied from the flow path switching unit 72 via the body cleaning flow path 75 onto the outer peripheral surface (body) of the cleaning nozzle 85. In this way, the nozzle cleaning unit 44 cleans the cleaning nozzle 85.

[0035] The ejection flow path 76 is a conduit that connects the flow path switching valve 70 and the ejection unit 77. The ejection unit 77 is, for example, a nozzle that sprays water supplied from the flow path switching unit 72 via the ejection flow path 76 in the form of mist into the bowl of the toilet 200. By spraying water into the bowl, it is possible to prevent dirt from adhering to the inside of the toilet 200.

[0036] The flow path switching unit 72 switches between opening and closing the bottom cleansing flow path 80a, the soft cleansing flow path 80b, the bidet cleansing flow path 80c, the body cleansing flow path 75, and the jetting flow path 76. When each flow path is opened, water is supplied and a water-passing state is established in which water flows. When each flow path is closed, a water-stopped state is established in which water supply is stopped (for example, a state in which water does not flow).

[0037] The flow path switching unit 72 switches between a state in which each of a plurality of water outlets, such as the water outlet provided in the cleaning nozzle 85 and the water outlet provided in the nozzle cleaning unit 44, is connected to the pipeline 110 and a state in which it is not connected to the pipeline 110. The flow path switching valve 70 (flow path switching unit 72) switches the flow path through which water flows among the plurality of flow paths connected downstream of the flow path switching valve 70. In other words, the flow path switching valve 70 selects a flow path that supplies water to the downstream side from the plurality of flow paths connected downstream of the flow path switching valve 70.

[0038] The control unit 130 is a control circuit including an electric circuit such as a CPU (Central Processing Unit). The control unit 130 receives power from a power supply circuit 135 and controls the operation of the solenoid valve 120, the heat exchanger unit 123, the electrolytic cell unit 126, the pressure modulation unit 127, the flow rate adjustment unit 71, the flow path switching unit 72, the drive motor 50, etc. based on signals from the seating detection sensor 150, the flow rate sensor 124, the operation unit 140, etc. In this way, the control unit 130 controls the operation of the nozzle unit 60.

[0039] FIG. 3 is a schematic perspective view illustrating the local cleaning device according to the embodiment. Fig. 4 is a schematic diagram showing the left side view of the local washing device 30 included in the sanitary washing device 100. As shown in Fig. 4, the local washing device 30 includes a nozzle unit 60, a rack 53, a gear 52, a drive motor 50, and a rack guide 54.

[0040] The nozzle unit 60 is curved so as to be convex upward. The nozzle unit 60 has a cleaning nozzle 85 and a flow path switching valve 70 (flow path switching section 72) located on the rear side of the cleaning nozzle 85. The flow path switching valve 70 is connected to the rear end of the cleaning nozzle 85, which is curved so as to be convex upward.

[0041] The nozzle unit 60 moves back and forth between the casing 10 and the toilet bowl 200 described with reference to FIG. 1. FIGS. 3 and 4 (excluding the two-dot chain line) show the stored state in which the nozzle unit 60 is in the retracted position. In the stored state, the tip of the nozzle unit 60 is located rearward of the front end of the case cover 12 and is located below the case cover 12. For example, the nozzle unit 60 in the stored state is located rearward of the opening / closing lid 12a provided on the case cover 12 and is stored between the case cover 12 and the case plate 11 (see FIG. 1). The retracted position is, for example, the rearmost position within the movable range of the nozzle unit 60. As shown in FIG. 4, in a side view, the rear portion of the cleaning nozzle 85 is inclined upward toward the front, and the front portion of the cleaning nozzle 85 is inclined downward toward the front. In other words, for example, in the stored state, the upper end (vertex) of the cleaning nozzle 85 or the nozzle unit 60 is located midway in the front-to-rear direction of the nozzle unit 60.

[0042] In Figure 4, the washing nozzle 85 and the opening / closing lid 12a are shown by two-dot chain lines in the extended state where the nozzle unit 60 has moved to the extended position. In the extended state, the tip of the nozzle unit 60 is located forward of the front end of the case cover 12. For example, the tip of the nozzle unit 60 in the extended state is located forward of the opening / closing lid 12a, and is advanced to a position inside the toilet bowl 200 forward of the casing 10. When the nozzle unit 60 advances into the toilet bowl 200, the opening / closing lid 12a is pressed against it and opens. The extended position is, for example, the forwardmost position within the movable range of the nozzle unit 60. The tip of the nozzle unit 60 in the extended state is forward and lower than the tip of the nozzle unit 60 in the stored state.

[0043] The rack 53 is a flexible rack (cable rack). The rack 53 has flexibility that allows it to move within the curved rack guide 54 (passage 54g). The rack 53 can be made of, for example, resin. The rack 53 has a tip portion 53t that is the front end, and a rear end portion 53r that is the end opposite the tip portion 53t in the extension direction along the rack guide 54. The tip portion 53t of the rack 53 is connected to the engagement portion 73c of the nozzle unit 60.

[0044] The gear 52 is a gear wheel that is substantially circular in side view. The teeth of the gear 52 engage with the teeth of the rack 53. A plurality of teeth that engage with the gear 52 are arranged on the surface of the rack 53 facing the gear 52 in the extension direction of the rack 53. The rack 53 is a rack gear that converts the rotational motion of the gear 52 into linear motion.

[0045] The drive motor 50 engages with a gear 52. The gear 52 is attached to the rotation shaft of the drive motor 50. The driving force of the drive motor 50 is transmitted to the rack 53 via the gear 52, causing the rack 53 to move. The drive motor 50 moves the rack 53, thereby moving the nozzle unit 60 forward and backward.

[0046] The rack 53, which is moved by the driving force of the drive motor 50, is guided by a rack guide 54. The rack guide 54 is a portion that houses the rack 53 and slidably holds the rack 53. The rack guide 54 defines a path 54g (the track of the rack 53) along which the rack 53 moves.

[0047] More specifically, the rack guide 54 has a first guide surface g1 and a second guide surface g2 that guide the rack 53. A passage 54g is formed between the first guide surface g1 and the second guide surface g2. The rack 53 slides along the first guide surface g1 and the second guide surface g2 by contacting the first guide surface g1 and the second guide surface g2.

[0048] For example, when the gear 52 is rotated clockwise by the drive motor 50 from the stored state shown in Fig. 4, the rack 53 moves forward within the curved rack guide 54 from the position shown in Fig. 4. That is, the tip end 53t of the rack 53 moves forward along an arc-shaped path within the first curved portion 541 of the rack guide 54, along arrow A1. The rear end 53r of the rack 53 moves along arrow A2 from the straight portion 544 of the rack guide 54, through the second curved portion 542, to the straight portion 543. The nozzle unit 60 advances into the toilet bowl 200 as the rack 53 presses the engagement portion 73c forward.

[0049] On the other hand, for example, when the gear 52 rotates counterclockwise from a state in which the rack 53 moves forward and the nozzle unit 60 is in the advanced state, the rack 53 moves rearward. The rack 53 moves rearward within the curved rack guide 54 and returns to the position shown in FIG. 4. That is, the tip end 53t of the rack 53 moves rearward along an arc-shaped path within the first curved portion 541 of the rack guide 54 in the opposite direction of arrow A1. The rear end 53r of the rack 53 moves from the straight portion 543 of the rack guide 54 through the second curved portion 542 to the straight portion 544 in the opposite direction of arrow A2. The rack 53 presses the engagement portion 73c rearward, causing the nozzle unit 60 to retreat into the casing 10.

[0050] In this way, the nozzle unit 60 can move between the advanced position and the retracted position along an arc-shaped trajectory by the driving force of the drive motor 50 transmitted via the gear 52 and the rack 53.

[0051] The local cleansing device 30 further includes a support part 40. The support part 40 is fixed to, for example, the casing 10 (see FIG. 1). The support part 40 slidably supports the nozzle unit 60. The support part 40 is positioned below the nozzle unit 60 and supports the nozzle unit 60 from below.

[0052] The support part 40 is provided so as to be located, for example, above the top surface 200t (rim surface, see FIG. 1) of the toilet bowl 200. For example, in the stored state, the nozzle unit 60 is above the top surface 200t. This prevents dirty water from entering the private parts cleansing device 30, and prevents the support part 40 and the nozzle unit 60 from becoming soiled.

[0053] FIG. 5 is a schematic perspective view illustrating the nozzle unit according to the embodiment. The cleaning nozzle 85 has a curved (or bent) cylindrical nozzle body 80 and a curved cylindrical nozzle cover 90 that covers the outer periphery of the nozzle body 80.

[0054] The tip of the cleaning nozzle 85 is provided with water outlets (posterior cleansing water outlet 83a, soft cleansing water outlet 83b, bidet cleansing water outlet 83c) that discharge water toward the upper human body parts when the nozzle unit 60 is in the extended state. The posterior cleansing flow path 80a, soft cleansing flow path 80b, and bidet cleansing flow path 80c, which are schematically shown in Figure 2, are provided inside the nozzle body 80.

[0055] The posterior cleansing flow path 80a causes water to flow from the flow path switching unit 72 to the posterior cleansing water discharge port 83a. The posterior cleansing water discharge port 83a discharges water supplied from the flow path switching unit 72 via the posterior cleansing flow path 80a. The soft wash flow path 80b causes water to flow from the flow path switching unit 72 to the soft wash water discharge port 83b. The soft wash water discharge port 83b discharges the water supplied from the flow path switching unit 72 via the soft wash flow path 80b. The bidet flush flow path 80c allows water to flow from the flow path switching unit 72 to the bidet flush water spout 83c. The bidet flush water spout 83c spouts the water supplied from the flow path switching unit 72 via the bidet flush flow path 80c.

[0056] The flow path switching valve 70 is connected to, for example, the rear end of the nozzle body 80. The flow path switching valve 70 has a case 73 that houses a flow path switching unit 72. The flow path switching unit 72 has a valve body 72a. The valve body 72a can be, for example, a rotor and a stator. For example, the stator is disk-shaped and has ports (openings) connected to each flow path. The rotor is disk-shaped and is arranged upstream of the stator so as to face the stator. A drive mechanism having an electric motor such as a motor or solenoid rotates the rotor. As the rotor rotates while in contact with the stator, the rotor switches between a state in which it closes and a state in which it opens the port. When a port is closed, the flow path connected to that port is stopped from flowing. When a port is opened, the flow path connected to that port is allowed to flow. However, the flow path switching unit 72 can be configured in any way that can switch the flow path through which water flows.

[0057] The case 73 is attached to, for example, the nozzle body 80. A portion of the case 73 may be formed integrally with a portion of the nozzle body 80. The nozzle cover 90 is attached to the case 73 and the nozzle body 80. As a result, the nozzle unit 60, the flow path switching valve 70, the nozzle body 80, and the nozzle cover 90, slide in the front-to-rear direction relative to the support part 40 as a single unit.

[0058] By curving the cleaning nozzle 85 so that it is convex upward in this way, the height (vertical width) can be reduced in the stored state, and the cleaning nozzle can be advanced to a lower position in the advanced state. In other words, a nozzle unit with high cleaning performance can be provided while keeping the height low.

[0059] The case 73 has a protrusion 73a and a recess 73b. The protrusion 73a and the recess 73b are engaging portions that engage with parts of the support part 40 (groove parts 45 and rail parts 46 described below). The protrusion 73a protrudes outward from the outer periphery of the case 73. The recess 73b is provided on the outer periphery of the case 73.

[0060] In this example, an engagement portion 73c at which the nozzle unit 60 is connected to the rack 53 (see FIG. 4) is provided on the case 73. The engagement portion 73c is a protrusion that protrudes laterally from the outer periphery of the case 73.

[0061] FIG. 6 is a schematic perspective view illustrating a support portion according to the embodiment. The support part 40 has a main body part 41 and a cover part 48 that covers the side of the main body part 41 . FIG. 7 is a schematic perspective view illustrating a main body portion of the support portion according to the embodiment. FIG. 8 is a schematic top view illustrating the main body of the support according to the embodiment. For example, as shown in FIG. 6 , the main body 41 has a nozzle arrangement section 42, a vertical section 43, and a nozzle cleaning section 44. The nozzle arrangement section 42 is, for example, the bottom of the main body 41 and extends in the front-to-rear direction. The nozzle arrangement section 42 is a portion above which the nozzle unit 60 in the stored state is disposed. The upper surface 42t of the nozzle arrangement section 42 has a curved shape that is convex upward corresponding to the shape of the nozzle cover 90. The nozzle unit 60 is curved to fit along the upper surface 42t in the stored state. That is, the nozzle unit 60 is stored above the upper surface 42t of the nozzle arrangement section 42 so as to fit along the upper surface 42t. The upper surface 42t may have, for example, a smoothly curved shape, or may be curved at a constant curvature.

[0062] The vertical portion 43 is a plate-like member extending upward from the nozzle arrangement portion 42. The vertical portion 43 is curved to be convex upward in accordance with the shape of the nozzle cover 90.

[0063] 7, the support part 40 has a groove part 45 that extends in the direction of advancement and retreat of the nozzle unit 60. In this example, the groove part 45 is a slit-shaped opening that penetrates the vertical part 43 in the thickness direction (left and right direction) and extends in the front and rear direction. The groove part 45 is curved so as to be convex upward in accordance with the shape of the nozzle cover 90.

[0064] 6 or 8, the support part 40 has a rail part 46 that extends in the direction of advancement and retreat of the nozzle unit 60. The rail part 46 is a plate-like part that protrudes in the left-right direction from the nozzle arrangement part 42 and extends in the front-rear direction. The rail part 46 is curved so as to be convex upward in accordance with the shape of the nozzle cover 90.

[0065] These groove portion 45 and rail portion 46 become engaged portions with which a part of the nozzle unit 60 engages. The groove portion 45 and rail portion 46 serve as portions that guide the nozzle unit 60 when the nozzle unit 60 is moved back and forth between the inside of the casing 10 and the inside of the toilet bowl 200.

[0066] That is, the protrusion 73a (see FIG. 5) of the nozzle unit 60 engages with the groove 45 by being inserted into the groove 45. The protrusion 73a is held slidably along the groove 45. The recess 73b (see FIG. 5) of the nozzle unit 60 engages with the rail 46 by sandwiching the rail 46. The recess 73b is held slidably along the rail 46. In this way, the nozzle unit 60 is held slidably relative to the support part 40 by the groove 45 and the rail 46. Because the groove 45 and the rail 46 are curved in the front-rear direction, the nozzle unit 60 advances and retreats along an arc-shaped trajectory.

[0067] As shown in FIGS. 6 to 8, the nozzle cleaning unit 44 is provided on the front end side of the nozzle arrangement unit 42 and the vertical unit 43. In this example, the nozzle cleaning unit 44 is provided as part of the main body unit 41. The nozzle cleaning unit 44 covers the outer periphery of the nozzle cover 90. A water outlet 44a (see FIG. 7) is provided on the inner periphery of the nozzle cleaning unit 44. Water from the flow path switching unit 72 is supplied to the nozzle cleaning unit 44 by the body cleaning flow path 75. The nozzle cleaning unit 44 discharges the water supplied by the body cleaning flow path 75 from the water outlet 44a toward the nozzle cover 90 of the cleaning nozzle 85. In this way, the nozzle cleaning unit 44 cleans the outer periphery surface (body) of the nozzle cover 90.

[0068] 8, in this example, the support part 40 has a motor arrangement part 47a. The motor arrangement part 47a is provided behind the nozzle arrangement part 42 of the main body part 41 and covers the drive motor 50. In other words, the drive motor 50 is housed in the motor arrangement part 47a of the support part 40.

[0069] 7, the support part 40 further includes a gear arrangement part 47b. The gear arrangement part 47b is provided adjacent to the side of the motor arrangement part 47a. The gear 52 is arranged in the gear arrangement part 47b. That is, the gear 52 is housed in the support part 40 and is located on the side surface of the main body part 41.

[0070] FIG. 9 is a schematic perspective view illustrating a cover portion of the support portion according to the embodiment. In this example, the rack guide 54 is provided integrally with the support portion 40. In other words, the rack guide 54 is included in the support portion 40. The support portion 40 of the nozzle unit 60 also serves as a support portion for the rack guide 54.

[0071] For example, the space between the cover portion 48 (see FIG. 9) and the main body portion 41 (see FIG. 7) forms a passage 54g of the rack guide 54. At least a portion of the rack guide 54 is integral with the cover portion 48 and is included in the cover portion 48 formed as a single member.

[0072] 9, the support part 40 is provided with a first convex part 48a and a second convex part 48b. A passage 54g of the rack guide 54 is formed between the first convex part 48a and the second convex part 48b. The first convex part 48a and the second convex part 48b protrude in the left-right direction from a side surface of the support part 40 (in this example, the side surface 48s of the cover part 48) and extend in the front-rear direction.

[0073] The first convex portion 48a has a front portion Pa1 and a rear portion Pa2. The front portion Pa1 extends in the front-to-rear direction and curves upward in a convex shape in a side view. The rear portion Pa2 is located rearward of the front portion Pa1 and includes a curved portion that extends upward toward the rear. The first guide surface g1 described in FIG. 4 is a side surface of the first convex portion 48a.

[0074] The second convex portion 48b is curved in the same manner as the first convex portion 48a and extends along the first convex portion 48a so as to surround the outside of the first convex portion 48a. The second convex portion 48b has a front portion Pb1 adjacent to the front portion Pa1 of the first convex portion 48a and a rear portion Pb2 adjacent to the rear portion Pa2 of the first convex portion 48a. The second convex portion 48b is a parallel curved line separated by a predetermined distance from the first convex portion 48a. The second guide surface g2 described in FIG. 4 is a side surface of the second convex portion 48b.

[0075] Therefore, the rack guide 54 (passage 54g) has a first curved portion 541 and a second curved portion 542. The first curved portion 541 is curved so as to be convex upward in accordance with the shape of the cleaning nozzle 85. The first curved portion 541 corresponds to the passage between the front portion Pa1 and the front portion Pb1. The first curved portion 541 is curved with, for example, a constant curvature. For example, the first curved portion 541 is curved along the upper surface 42t (see FIG. 6) of the nozzle arrangement portion 42 and is a parallel curved line separated by a predetermined distance from the upper surface 42t. In a side view, the curvature of the first curved portion 541 may be substantially the same as the curvature of the upper surface 42t. The first curved portion 541 has an upwardly inclined portion extending rearward and a downwardly inclined portion continuing rearward from the rear end of the upwardly inclined portion.

[0076] The second curved portion 542 is located further rearward than the first curved portion 541. The second curved portion 542 includes a portion that curves in a direction intersecting the front-to-rear direction as it extends rearward. The second curved portion 542 corresponds to the passage between the rear portion Pa2 and the rear portion Pb2. In this example, the second curved portion 542 has a shape that convex rearward in a side view and is a folded portion that extends back and back in the front-to-rear direction. That is, the second curved portion 542 includes a portion P1 that curves upward as it extends rearward. The second curved portion 542 includes a portion P2 that is continuous from the upper end of portion P1 and curves forward as it extends upward. The second curved portion 542 is curved, for example, with a constant curvature.

[0077] For example, in a side view, at least a part of the first curved portion 541 and at least a part of the second curved portion 542 are aligned on a straight line extending in the front-rear direction. In this example, the first curved portion 541 is located between the upper and lower ends of the second curved portion 542 (folded portion) in the up-down direction.

[0078] Furthermore, the rack guide 54 may have a straight portion 543 and a straight portion 544. The straight portion 543 connects the first curved portion 541 and the second curved portion 542 and extends linearly in the front-to-rear direction. The gear 52 located between the first curved portion 541 and the second curved portion 542 meshes with the rack 53 at the straight portion 543. The straight portion 544 extends linearly in the front direction from the upper end of the second curved portion 542.

[0079] 9, the first convex portion 48a and the second convex portion 48b are provided on the cover portion 48, but at least a portion of the first convex portion 48a and the second convex portion 48b may be provided on the main body portion 41 side. At least a portion of the rack guide 54 may be integral with the main body portion 41, or may be included in the main body portion 41 formed as a single member. Furthermore, at least a portion of the passage 54g of the rack guide 54 may be formed as a groove (recess) provided on the side surface of the support portion 40.

[0080] 4, when the nozzle unit 60 is in the stored state, the cleaning nozzle 85 is adjacent to the first curved portion 541 in the left-right direction and is located further forward than the second curved portion 542. When the nozzle unit 60 is in the stored state, the cleaning nozzle 85 is curved so as to follow the first curved portion 541. Because the cleaning nozzle 85 can be stored so as to follow the first curved portion 541, the height of the sanitary washing device 100 can be further reduced.

[0081] The curvature of the cleaning nozzle 85 (nozzle cover 90) may be the same as the curvature of the first curved portion 541 in a side view. For example, the first curved portion 541 has a curved shape parallel to the cleaning nozzle 85 (nozzle cover 90) in the housed state.

[0082] When the nozzle unit 60 is in the stored state, the cleaning nozzle 85 is disposed above the upper surface 42t of the nozzle arrangement portion 42 described in FIG. 6 and other figures. In this manner, the curved cleaning nozzle 85 is disposed on the curved upper surface 42t of the support portion 40. This allows the cleaning nozzle 85 to be advanced forward and downward, enabling water to be ejected from below when cleaning private parts. This makes it possible to provide a nozzle unit with high cleaning performance while keeping the height low.

[0083] FIG. 10 is a schematic side view illustrating a part of the local cleaning device according to the embodiment. FIG. 10 shows the nozzle unit 60 and a part of the support part 40 as viewed from the side, with the nozzle unit 60 in the stored state. 10, the flow path switching valve 70 of the nozzle unit 60 has an ejection outlet 74a, an inlet 74b, and a body cleaning outlet 74c. The ejection outlet 74a, the inlet 74b, and the body cleaning outlet 74c are provided in, for example, a case 73 that houses the flow path switching unit 72, and are openings that communicate with the flow path switching unit 72 inside the case 73.

[0084] In this example, protrusions 78a, 78b, and 78c, which are attachment portions for the flow paths, are provided on the right side surface of the case 73. In the stored state, the protrusions 78a, 78b, and 78c are provided so as to protrude rearward and downward. The protrusion 78a is located above the protrusion 78b, and the protrusion 78b is located above the protrusion 78c. The jet outlet 74a, the inlet 74b, and the body cleaning outlet 74c are openings provided at the rear ends of the protrusions 78a, 78b, and 78c, respectively. The inlet 74b is an inlet through which water flows into the nozzle unit 60, and the jet outlet 74a and the body cleaning outlet 74c are outlets through which water flows out of the nozzle unit 60.

[0085] A water supply passage 79 (see FIG. 3) that supplies water to the inlet 74b is connected to the protruding portion 78b. Water supplied from the upstream side to the nozzle unit 60 through the water supply passage 79 flows into the passage switching valve 70 from the inlet 74b and flows to the passage switching portion 72. The body cleaning flow path 75 (see FIG. 3) is connected to the protrusion 78c. When the flow path switching unit 72 opens the body cleaning flow path 75, the water that has flowed into the flow path switching valve 70 flows out from the flow path switching unit 72 to the body cleaning flow path 75 via the body cleaning outlet 74c. The protrusion 78a is connected to the ejection flow path 76 (see FIG. 3). When the flow path switching unit 72 opens the ejection flow path 76, the water that has flowed into the flow path switching valve 70 flows out from the flow path switching unit 72 to the ejection flow path 76 via the ejection outlet 74a.

[0086] The water supply passage 79, the body cleaning passage 75, and the jetting passage 76 are flexible tubes (or hoses) made of, for example, a resin material. The protrusion 78c (body cleaning outlet 74c), the protrusion 78b (inlet 74b), and the protrusion 78a (jet outlet 74a) are connection ports for the tubes. The connection ports are inserted into the tubes to connect them.

[0087] The nozzle cleaning section 44 has a cleaning section inlet 44c. In this example, a protrusion 44b, which is an attachment part of the flow path, is provided on the right side surface of the nozzle cleaning section 44. The protrusion 44b is provided so as to protrude to the right. The cleaning section inlet 44c is an opening provided at the right end of the protrusion 44b. The protrusion 44b (cleaning section inlet 44c) is a connection port for a flexible tube. As described above, one end (inlet) of the body cleaning flow path 75 is connected to the protrusion 78c (body cleaning outlet 74c). The other end (outlet 75p (see Figure 12)) of the body cleaning flow path 75 is connected to the protrusion 44b (cleaning section inlet 44c). Water that flows into the body cleaning flow path 75 from the body cleaning outlet 74c flows into the nozzle cleaning section 44 from the cleaning section inlet 44c.

[0088] In the stored state in which the washing nozzle 85 is stored, the water outlet 83 of the washing nozzle 85 is located above the inlet 74b of the flow path switching valve 70. That is, the height H74b (vertical position) of the inlet 74b is lower than the height H83 (vertical position) of the water outlet 83. The water outlet 83 is a water outlet that discharges water toward the human body private parts, and is, for example, the above-mentioned posterior cleansing water outlet 83a, soft cleansing water outlet 83b, or bidet cleansing water outlet 83c. For example, in the stored state, the inlet 74b is located below all of the water outlets 83 provided in the washing nozzle 85.

[0089] When the cleaning nozzle 85 (nozzle unit 60) is stored, the water outlet 83 is positioned higher than the inlet 74b, which prevents water from dripping from the water outlet 83. For example, in the stored state, it is easy to form a slope that slopes downward toward the rear in the flow path from the inlet 74b to the water outlet 83. Therefore, for example, water remaining in the cleaning nozzle 85 is prevented from dripping unintentionally from the water outlet 83 in front.

[0090] When the cleaning nozzle 85 is advanced, the water outlet 83 is located below the inlet 74b. For example, by advancing the cleaning nozzle 85, the water inside the nozzle can be discharged from the water outlet 83. For example, water can be drained at a desired timing.

[0091] Furthermore, in the stored state in which the cleaning nozzle 85 is stored, the outlet of the body cleaning flow path 75 is located above the inlet 74b of the flow path switching valve 70. As described above, the outlet of the body cleaning flow path 75 is connected to the cleaning section inlet 44c. The height H75b (vertical position) of the outlet of the body cleaning flow path 75 shown in FIG. 10 is approximately the same as the position of the cleaning section inlet 44c. The height H74b of the inlet 74b is lower than the height H75b of the outlet of the body cleaning flow path 75.

[0092] When the cleaning nozzle 85 is stored, the outlet of the body cleaning flow path 75 is located higher than the inlet 74b, which prevents water from dripping from the nozzle cleaning unit 44. For example, in the stored state, it is easy to form a slope that slopes downward toward the rear in the flow path from the inlet 74b of the flow path switching valve 70 to the outlet of the body cleaning flow path 75. This prevents water remaining in the body cleaning flow path 75 from dripping from the water outlet 44a, for example. This prevents water from dripping unintentionally from the body cleaning flow path 75, for example. The height H74b of the inlet 74b may be lower than the height (vertical position) of the water outlet 44a of the nozzle cleaning unit 44.

[0093] FIG. 11 is a schematic cross-sectional view illustrating the nozzle unit according to the embodiment. 11 shows the nozzle unit in the stored state. Inside the nozzle body 80 of the cleaning nozzle 85, there is provided a flow path 81 that supplies water to the water outlet 83. For example, the nozzle body 80 and the flow path 81 have a bent shape that is convex upward when in the stored state.

[0094] The flow path 81 has an apex 81t, a first inclined portion 81a, and a second inclined portion 81b. The apex 81t is the portion of the flow path 81 that is located at the highest position in the stored state. The flow path 81 is bent at the apex 81t. The first inclined portion 81a is a pipe that descends from the apex 81t toward the front in the stored state, i.e., a downward inclined portion toward the front. The second inclined portion 81b is a pipe that descends from the apex 81t toward the rear in the stored state, in other words, an upward inclined portion toward the front. The apex 81t is the portion where the flow path 81 changes from an upward inclination to a downward inclination in the stored state. Water flows from the first inclined portion 81a to the second inclined portion 81b in the flow path 81 and is discharged from the water outlet 83.

[0095] When the nozzle unit 60 is in the stored state, the top 81t of the flow path 81 is above the water outlet 83 to which water is supplied by the flow path 81, and above the inlet 74b of the flow path switching valve 70. In other words, the height H81t (vertical position) of the top 81t is higher than the height H83 of the water outlet 83 and higher than the height H74b of the inlet 74b. Water can collect in the section of the flow path 81 upstream of the top 81t, which can further prevent water remaining in the cleaning nozzle 85 from dripping from the water outlet 83.

[0096] The flow path 81 is, for example, a posterior cleansing flow path 80a, a soft cleansing flow path 80b, or a bidet cleansing flow path 80c. For example, the top 81t of the posterior cleansing flow path 80a is located higher than the posterior cleansing water outlet 83a and the inlet 74b in the stored state. For example, the top 81t of the soft cleansing flow path 80b is located higher than the soft cleansing water outlet 83b and the inlet 74b in the stored state. For example, the top 81t of the bidet cleansing flow path 80c is located higher than the bidet cleansing water outlet 83c and the inlet 74b in the stored state.

[0097] 12 to 14 are schematic top views illustrating a part of the local cleaning device according to the embodiment. 12 shows a first state S1 in which the nozzle unit 60 is located at a first position relative to the support part 40. The first state S1 is, for example, a stored state of the nozzle unit 60. FIG. 13 shows a second state S2 in which the nozzle unit 60 has advanced forward from the first state S1, and FIG. 14 shows a third state S3 in which the nozzle unit 60 has advanced further forward from the second state S2.

[0098] In each of the first state S1 to the third state S3, the body cleaning flow path 75 has a curved portion 75a, the water supply flow path 79 has a curved portion 79a, and the jet flow path 76 has a curved portion 76a. The curved portions 75a, 79a, and 76a are curved so as to convex rearward behind the cleaning nozzle 85.

[0099] One end of the curved portion 75a is connected to the body cleaning outlet 74c of the flow path switching valve 70, and the other end of the curved portion 75a extends forward. That is, the body cleaning flow path 75 extends rearward from the flow path switching valve 70 and is attached so as to turn back forward at the curved portion 75a. One end of the curved portion 79a is connected to the inlet 74b of the flow path switching valve 70, and the other end of the curved portion 79a extends forward. That is, the water supply flow path 79 extends rearward from the flow path switching valve 70 and is attached so as to turn back forward at the curved portion 79a. One end of the curved portion 76a is connected to the jet outflow outlet 74a of the flow path switching valve 70, and the other end of the curved portion 76a extends forward. That is, the jet flow path 76 extends rearward from the flow path switching valve 70 and is attached so as to turn back forward at the curved portion 76a.

[0100] A portion of the body cleaning flow path 75 forward of the curved portion 75a, a portion of the water supply flow path 79 forward of the curved portion 79a, and a portion of the jet flow path 76 forward of the curved portion 76a are held by a holding member 92, or their positions relative to the support part 40 are fixed by the holding member 92. The holding member 92 is attached to the support part 40, for example, and the position of the holding member 92 relative to the support part 40 is fixed.

[0101] In each of the first state S1 to the third state S3, the curvature of the curved portion 75a, the curvature of the curved portion 79a, and the curvature of the curved portion 76a are different from one another. For example, in the first state S1, the radius of curvature of the curved portion 76a is smaller than the radius of curvature of the curved portion 79a, which is smaller than the radius of curvature of the curved portion 75a. For example, in the second state S2, the radius of curvature of the curved portion 79a is smaller than the radius of curvature of the curved portion 76a, which is smaller than the radius of curvature of the curved portion 75a. For example, in the third state S3, the radius of curvature of the curved portion 75a is smaller than the radius of curvature of the curved portion 76a, which is smaller than the radius of curvature of the curved portion 79a.

[0102] The timing at which the curvature of the bending portion 75a, the timing at which the curvature of the bending portion 79a, and the timing at which the curvature of the bending portion 76a reaches its maximum are different from one another. For example, the radius of curvature of the bending portion 76a is larger in the second state S2 than in the first state S1, and larger in the third state S3 than in the second state S2. For example, the radius of curvature of the bending portion 79a is larger in the first state S1 than in the second state S2, and larger in the third state S3 than the first state S1. For example, the radius of curvature of the bending portion 75a is larger in the second state S2 than in the third state S3, and larger in the first state S1 than in the second state S2.

[0103] In this way, each tube bends (the way it bends changes) as the nozzle unit 60 moves forward or backward. When the nozzle unit 60 moves forward or backward, sliding resistance occurs in response to the bending of the tubes, and a load is applied to the drive motor 50. When the nozzle unit 60 moves forward or backward, the timing at which the force corresponding to the bending of a certain tube reaches its peak changes depending on the curvature of that tube at that time.

[0104] In contrast, the body cleaning flow path 75, the water supply flow path 79, and the jet flow path 76 are curved at different curvatures and connected to the flow path switching valve 70. This distributes the timing at which the load is applied to the drive motor 50, making it possible to suppress peaks in the load on the drive motor 50. For example, when the nozzle unit 60 moves forward and backward, the timing at which the force (motor load) corresponding to the bending of the body cleaning flow path 75 becomes maximum, the timing at which the force corresponding to the bending of the water supply flow path 79 becomes maximum, and the timing at which the force corresponding to the bending of the jet flow path 76 becomes maximum can be shifted from one another. For example, even with a small drive motor 50, it is possible to control the advancement and retreat of the nozzle unit 60, making it possible to realize a low-height nozzle unit 60.
