[0008] A first embodiment of the toilet device 1 will be described with reference to the drawings. In the following description, the front-to-back direction Y refers to the front direction as seen by a user seated on the toilet seat 22. In the front-to-back direction Y, the front side is the front side Y1 and the rear side is the rear side Y2. The left-to-right direction X refers to the left side as seen by a user seated on the toilet seat 22. In the left-to-right direction X, the left side as seen by a user seated on the toilet seat 22 is the left side X1 and the right side is the right side X2. The up-to-down direction Z refers to the up-to-down direction along the vertical direction relative to the floor surface on which the toilet bowl 21 is placed. In the up-to-down direction Z, the upper side is Z1 and the lower side is Z2. The cross section shown in Figure 5 is a cross section taken along line AA in Figure 2, cut along the front-to-back direction Y and the up-to-down direction Z, viewed in the left-to-right direction X.

[0009] As shown in Figure 1, the toilet apparatus 1 according to this embodiment comprises a toilet bowl 21, a toilet seat 22, a toilet lid 3, and a functional part 4. The toilet bowl 21 is formed with an opening facing upward. The toilet bowl 21 is made of, for example, ceramic or resin. The toilet seat 22 and the toilet lid 3 are attached above the toilet bowl 21 so as to be rotatable relative to the toilet bowl 21.

[0010] 1, the toilet bowl 21 has a toilet bowl 211 and an outer peripheral wall portion 212. The toilet bowl 211 is disposed on the front side Y1 of the toilet bowl 21. The outer peripheral wall portion 212 surrounds the outer surface of the toilet bowl 211 and the outside of the piping, etc.

[0011] As shown in Figure 1, the functional unit 4 is arranged above the rear part of the toilet bowl 21. As shown in Figures 2 and 3, the functional unit 4 includes at least a sanitary washing device 5 that washes the user's private parts. The functional unit 4 includes functional components including the sanitary washing device 5, a base plate 41, and a cover member 42 that covers the outer shape of the functional unit. At least some of the functional components of the functional unit 4 are arranged on the base plate 41.

[0012] The functional parts are installed on the base plate 41 or in other installation positions, taking into consideration various functions and their positional relationships with other parts. Examples of functional parts include a heater for the toilet seat 22, a toilet flushing device equipped with a flushing tank, a sanitary flushing device 5 that cleans the user's private parts, a hose, a power supply unit, a control circuit board, an electric opening and closing unit that electrically opens and closes the toilet seat and toilet lid 3, a valve unit, various pipes, etc.

[0013] 2 and 3, the sanitary washing device 5 has a pair of washing nozzles 51 that can move forward and backward, a shutter unit 52 that opens and closes a front opening 415 (opening) of the washing nozzles 51, and a shutter washing unit 6. The front opening 415 is formed on the front side Y1 of the functional unit 4.

[0014] The pair of cleaning nozzles 51 are arranged at a distance in the left-right direction X at the center of the front side Y1 of the functional part 4 in the left-right direction X. The pair of cleaning nozzles 51 are used for anal cleansing and bidet cleansing, respectively, to cleanse private parts of the human body. The cleaning nozzles 51 spray cleansing water toward the human body from a nozzle water outlet (not shown) provided at the top of the tip side.

[0015] 2 and 4, the shutter section 52 is disposed at the center in the left-right direction X on the front side Y1 of the functional section 4. The shutter section 52 is formed in the shape of a plate extending in the left-right direction X (lateral direction) of the toilet bowl 21.

[0016] When viewed from the front side Y1 as shown in FIG. 2 with the front opening 415 (see FIG. 3) closed, the shutter section 52 has an upper end formed in a straight line extending in the left-right direction X. The front opening 415 is formed in the center in the left-right direction X on the upper side Z1 of the base plate front surface 411 of the base plate 41. The lower end of the shutter section 52 is positioned lowest at the center in the left-right direction X and is curved in an arc shape that extends upward toward the outside in the left-right direction X. The shutter section 52 is rotatably attached to the base plate front surface 411 of the base plate 41 of the functional section 4.

[0017] 4 and 5, the base plate front surface 411 extends in the left-right direction and faces the front side Y1. The base plate front surface 411 has an upper vertical surface 412 and a lower inclined surface 413.

[0018] 5, the upper vertical surface 412 is formed in a flat shape extending a predetermined length in the up-down direction Z. The lower inclined surface 413 is connected to the lower end of the upper vertical surface 412 via a smoothly curved surface 414, and is formed in a flat shape with a downward slope that slopes downward from the front side Y1 to the rear side Y2. The length of the lower inclined surface 413 in the inclination direction is formed longer than the length of the upper vertical surface 412 in the up-down direction Z.

[0019] 2, when the shutter unit 52 is in the closed position, it is arranged along the base plate front surface 411 so as to cover part of the upper side of the base plate front surface 411, which is the front surface of the functional unit 4. In the range of the left-right direction X in which the shutter unit 52 is arranged, part of the upper side of the base plate front surface 411 is covered by the shutter unit 52. The lower part of the base plate front surface 411 that is not covered by the shutter unit 52 is exposed to the front side Y1.

[0020] 5, the shutter section 52 has an upper bent portion 521 and an inclined flat portion 522. When the shutter section 52 is in the closed position, the upper bent portion 521 bulges slightly toward the front side Y1 and extends in the up-down direction Z. When in the closed position, the inclined flat portion 522 extends in a flat shape with a downward slope that descends from the lower end of the upper bent portion 521 from the front side Y1 to the rear side Y2.

[0021] 5, the upper-end bent portion 521 is formed by bending the upper end of the shutter portion 52 rearward relative to the inclined flat surface portion 522 so that the front side is convex. The upper-end bent portion 521 is formed by bending the upper end of the inclined flat surface portion 522, which extends downwardly, rearward relative to an imaginary extension line K that linearly extends the inclined flat surface portion 522 to the upper side Z1.

[0022] As shown in Figures 3 and 5, the shutter unit 52 has a pair of protruding support parts 53 that protrude rearward from the upper side of the back surface 52b. The protruding support parts 53 have a cylindrical support shaft 531 that extends in the left-right direction X. The support shaft 531 is rotatably attached to a pair of C-shaped release locking parts 412a that are provided on the upper vertical surface 412 of the base plate front surface 411. When attached to the pair of protruding support parts 53, the shutter unit 52 is rotatable around a rotation axis J of the support shaft 531 that extends in the left-right direction X.

[0023] In this embodiment, the upper end of the shutter section 52 is formed to bend rearward. For example, when the shutter section 52 rotates from the closed position to the open position, if the entire shutter section 52 were formed linearly all the way to the upper end, the radius of the rotation trajectory of the upper end of the shutter section 52 would increase. In this case, it would be necessary to form a large gap between the upper end of the shutter section 52 and the components above the shutter section 52.

[0024] In contrast to this, in the present disclosure, the upper end of the shutter section 52 is bent rearward, so when the shutter section 52 is opened, the gap that accommodates the upper end of the shutter section 52 can be made smaller than if the shutter section 52 were formed in a straight line up to the upper end, as shown in Fig. 6, and therefore the gap between the upper end of the cover member 42 and the shutter section 52 can be made smaller. This makes it possible to reduce the gap between the cover member 42 and the shutter section 52, thereby reducing the gap that is visible from the outside and improving the design.

[0025] 3, a front opening 415 is formed in the center in the left-right direction X on the upper side Z1 of the base plate front surface 411 of the base plate 41. The cleaning nozzle 51 moves forward and backward, thereby entering and exiting through the front opening 415.

[0026] As the cleaning nozzle 51 advances and retreats, the back surface of the shutter unit 52 is pressed by the cleaning nozzle 51, thereby opening and closing a front opening 415 formed in front of the cleaning nozzle 51, as shown in Fig. 6. When the shutter unit 52 is in the closed position, as shown in Fig. 5, it is arranged to close the front opening 415 in the base plate front surface 411 of the base plate 41 of the functional unit 4.

[0027] As shown in Fig. 5, when the shutter section 52 is in the closed position, it is disposed with a gap S between it and the base plate front surface 411 of the base plate 41. A pair of protrusions 413a are formed on the lower inclined surface 413 of the base plate front surface 411 and spaced apart in the left-right direction X, as shown in Fig. 3. The pair of protrusions 413a form a gap S between the shutter section 52 and the lower inclined surface 413 of the base plate front surface 411, as shown in Fig. 5.

[0028] As a result, when the shutter section 52 is in the closed position, it comes into contact with the pair of protrusions 413a, forming a gap S between the shutter section 52 and the lower inclined surface 413 of the front surface 411 of the base plate. Cleaning water that is discharged from the back surface cleaning water discharger 62 of the shutter cleaning section 6, which will be described later, and moves along the back surface 52b of the shutter section 52 flows into the gap S.

[0029] The shutter cleaning unit 6 cleans the front surface 52a and back surface 52b of the shutter unit 52 when the shutter unit 52 closes the front opening 415. The shutter cleaning unit 6 is disposed above the upper end of the shutter unit 52. The shutter cleaning unit 6 discharges cleaning water downward onto the shutter unit 52 when the shutter unit 52 is in the closed position where the front opening 415 is closed.

[0030] In this embodiment, the phrases "a state in which the shutter unit 52 closes the front opening 415" and "a case in which the shutter unit 52 is located at a closed position in which the front opening 415 is closed" do not necessarily mean that the shutter unit 52 completely closes the front opening 415. The phrases "a state in which the shutter unit 52 closes the front opening 415" and "a case in which the shutter unit 52 is located at a closed position in which the front opening 415 is closed" also include a state in which the shutter unit 52 almost completely blocks the front opening 415 when the shutter unit 52 is pushed slightly open by the cleaning nozzle 51, for example.

[0031] As shown in FIGS. 5 and 6, the shutter cleaning section 6 has a front cleaning water discharger 61 (first water discharger) and a back cleaning water discharger 62 (second water discharger).

[0032] As shown in Figures 3 and 4, the front flushing water discharger 61 has multiple front flushing outlets 611. The multiple front flushing outlets 611 discharge flushing water onto the front surface 52a of the shutter section 52. The back flushing water discharger 62 has multiple back surface flushing outlets 621. The multiple back surface flushing outlets 621 discharge flushing water onto the back surface 52b of the shutter section 52.

[0033] The front flushing water discharger 61 and the back flushing water discharger 62 discharge flush water that is temporarily stored in the flushing water storage section 63. As shown in Figures 2, 4 and 5, the flushing water storage section 63 is located inside the cover member 42, at the top of the front part of the functional section 4. The flushing water storage section 63 is formed in a hollow shape that extends in the left-right direction X. The underside 632 of the flushing water storage section 63 is formed in a flat shape that has a width in the front-rear direction Y and extends in the left-right direction X.

[0034] A plurality of front face water outlets 611 of the front face washing water outlet 61 and a plurality of back face water outlets 621 of the back face washing water outlet 62 are formed on the underside 632 of the flush water storage section 63. A flush water supply flow path 631 is connected to each end of the flush water storage section 63 in the left-right direction X, as shown in Figures 4 and 5. Flush water is introduced into the flush water storage section 63 via the flush water supply flow path 631 and stored therein. The flush water temporarily stored in the flush water storage section 63 is discharged towards the shutter section 52 by the plurality of front face water outlets 611 of the front face washing water outlet 61 and the plurality of back face water outlets 621 of the back face washing water outlet 62.

[0035] As shown in Figures 5 and 6, the multiple front water outlets 611 and the multiple rear water outlets 621 are arranged in two rows, front to back, on the underside 632 of the flush water storage section 63. As shown in Figure 4, the multiple front water outlets 611 are arranged on the front side Y1 of the underside 632 of the flush water storage section 63, and the multiple rear water outlets 621 are arranged on the rear side Y2. The multiple front water outlets 611 and the multiple rear water outlets 621 are arranged in a straight line in the left-right direction X, alternately so that their positions in the left-right direction X do not overlap, in the area where the shutter section 52 in the left-right direction X is provided.

[0036] As shown in Figure 3, the multiple front water discharge ports 611 are formed by through-holes that penetrate the underside 632 of the flush water storage section 63 in the up-down direction Z on the front side Y1 of the underside 632 of the flush water storage section 63. As shown in Figure 5, the multiple front water discharge ports 611 open downwards so as to cause flush water to flow along the front surface 52a of the shutter section 52 when the shutter section 52 is in the closed position.

[0037] The multiple front water outlets 611 open above the surface 521a of the front side Y1 of the upper bent portion 521 of the shutter section 52, facing downward in a direction along the surface 521a of the front side Y1 of the upper bent portion 521. As a result, the wash water discharged from the multiple front water outlets 611 is discharged so as to follow the surface 521a of the front side Y1 of the upper bent portion 521 of the shutter section 52, and flows along the front surface 52a of the shutter section 52, thereby cleaning the front surface 52a of the shutter section 52.

[0038] As shown in Figure 3, the multiple rear surface water outlets 621 are formed by through holes that penetrate the underside 632 of the flush water storage section 63 in the up-down direction Z, on a side Y2 rearward of the multiple front surface water outlets 611 on the underside 632 of the flush water storage section 63. As shown in Figure 5, the multiple rear surface water outlets 621 open downwards so as to cause flush water to flow along the back surface 52b of the shutter section 52 when the shutter section 52 is in the closed position.

[0039] The multiple back surface water outlets 621 open downward, in a direction along the surface 521b of the rear side Y2 of the upper end bent portion 521 of the shutter section 52. As a result, the cleaning water discharged from the multiple back surface water outlets 621 is discharged so as to flow along the surface 521b of the rear side Y2 of the upper end bent portion 521 of the shutter section 52, and flows along the back surface 52b of the shutter section 52, thereby cleaning the back surface 52b of the shutter section 52.

[0040] The cleaning water discharged from the multiple rear surface water discharge ports 621 flows along the rear surface 52b of the shutter section 52, and then flows along the front surface 411 of the base plate of the functional section 4. This allows the shutter cleaning section 6 to clean the front surface 411 of the base plate of the functional section 4 with the cleaning water discharged from the multiple rear surface water discharge ports 621.

[0041] In the shutter cleaning unit 6 described above, the front cleaning water discharger 61 and the back cleaning water discharger 62 discharge the cleaning water stored in the cleaning water storage unit 63 downward at the same time when the shutter unit 52 is closed. This allows the shutter cleaning unit 6 to clean the front surface 52a and the back surface 52b of the shutter unit 52 simultaneously.

[0042] 5, when the shutter section 52 is closed, the front flushing water discharger 61 discharges flushing water downward from multiple front flushing outlets 611, thereby discharging flushing water onto the surface 521a on the front side Y1 of the upper bent portion 521 of the shutter section 52. The flushing water discharged onto the surface 521a on the front side Y1 of the upper bent portion 521 of the shutter section 52 flows along the front surface 52a of the shutter section 52.

[0043] The cleaning water flowing along the front surface 52a of the shutter section 52 flows along the front side Y1 surface 522a of the inclined flat surface 522 due to the surface tension of the water on the front side Y1 surface 522a of the inclined flat surface 522 on the front surface 52a of the shutter section 52. In this way, the front surface cleaning water discharger 61 discharges cleaning water from the multiple front surface water discharge ports 611 to clean the front surface 52a of the shutter section 52.

[0044] 5, when the shutter section 52 is closed, the back surface cleaning water discharger 62 discharges cleansing water downward from multiple back surface water discharge ports 621, thereby discharging cleansing water onto the surface 521b of the rear side Y2 of the upper end bent portion 521 of the shutter section 52. The cleansing water discharged onto the surface 521b of the rear side Y2 of the upper end bent portion 521 of the shutter section 52 flows along the back surface 52b of the shutter section 52.

[0045] The cleaning water flowing along the back surface 52b of the shutter section 52 passes through the gap S between the back surface 52b of the shutter section 52 and the lower inclined surface 413 of the front surface 411 of the base plate of the functional section 4, and due to the surface tension of the water, flows along the lower part of the lower inclined surface 413 of the front surface 411 of the base plate. As a result, the cleaning water that has cleaned the back surface 52b of the shutter section 52 not only cleans the back surface 52b of the shutter section 52, but also cleans the lower part of the lower inclined surface 413 of the front surface 411 of the base plate of the functional section 4.

[0046] The shutter cleaning unit 6 performs an operation of cleaning the shutter unit 52 at a predetermined timing. The predetermined timing at which the shutter cleaning unit 6 performs the operation of cleaning the shutter unit 52 may be any timing as long as the shutter unit 52 is in a closed state, and may be, for example, a timing before the cleaning nozzle 51 performs a cleaning operation of cleaning a local part of the human body, a timing after the cleaning nozzle 51 has completed a cleaning operation of cleaning a local part of the human body, or the same timing as the timing at which the cleaning nozzle 51 is cleaned with cleaning water.

[0047] The sanitary washing device 5 of this embodiment described above provides the following effects.

[0048] The sanitary cleaning device 5 of this embodiment comprises a shutter section 52 that opens and closes a front opening 415 formed in the functional section 4, and a shutter cleaning section 6 that is arranged above the shutter section 52 and cleans the front surface 52a of the shutter section 52 while the shutter section 52 closes the front opening 415.

[0049] Therefore, a shutter cleaning section 6 that is separate from the shutter section 52 can be provided above the shutter section 52, which is a movable section. This allows cleaning to be done by the shutter cleaning section 6 that is separate from the shutter section 52. Therefore, the shutter section 52 can have a simple configuration. Furthermore, the front surface 52a of the shutter section 52 can be cleaned with the shutter section 52 closing the front opening 415. Therefore, it is possible to prevent cleaning water discharged from the shutter cleaning section 6 from splashing onto the front side Y1 of the toilet bowl 21.

[0050] In this embodiment, the shutter cleaning unit 6 can clean the back surface 52b of the shutter unit 52 while the shutter unit 52 closes the front opening 415. This allows the shutter cleaning unit 6 to clean both the front surface 52a and the back surface 52b of the shutter unit 52.

[0051] In this embodiment, the shutter cleaning unit 6 can simultaneously clean the front surface 52a and the back surface 52b of the shutter unit 52 while the shutter unit 52 is in a state where the front opening 415 is closed. This allows the front surface 52a and the back surface 52b of the shutter unit 52 to be simultaneously cleaned in a short time.

[0052] In this embodiment, the shutter cleaning section 6 has a front cleaning water discharger 61 that discharges cleaning water onto the front surface 52a of the shutter section 52, and a back surface cleaning water discharger 62 that discharges cleaning water onto the back surface 52b of the shutter section 52. As a result, the front surface 52a of the shutter section 52 can be cleaned by the front surface cleaning water discharger 61, and the back surface 52b of the shutter section 52 can be cleaned by the back surface cleaning water discharger 62, so that both the front surface 52a and the back surface 52b of the shutter section 52 can be cleaned efficiently.

[0053] In this embodiment, the shutter cleaning unit 6 discharges cleaning water downward. As a result, the shutter unit 52 is positioned below the shutter cleaning unit 6, so that cleaning water can be discharged in the direction of gravity. This makes it easy to clean the shutter unit 52.

[0054] In this embodiment, the upper end of the shutter portion 52 is formed so as to bend rearward. Therefore, when the shutter portion 52 is opened, the gap between the upper end of the cover member 42 and the shutter portion 52 can be made smaller than if the shutter portion 52 were formed in a straight line up to its upper end. This makes it possible to reduce the gap between the cover member 42 and the shutter portion 52, thereby improving the design.

[0055] In this embodiment, the shutter section 52 is arranged along the front surface 411 of the base plate so as to cover a part of the front surface 411 of the base plate of the functional section 4, and the functional section 4 is formed with a protrusion 413a that forms a gap S between the back surface 52b of the shutter section 52 and the front surface 411 of the base plate of the functional section 4. This allows the back surface cleaning water-spouting section 62 to clean the back surface 52b of the shutter section 52 and also the lower part of the front surface 411 of the base plate of the functional section 4.

[0056] A sanitary washing device 5A of the second embodiment will be described. The description of the first embodiment can be applied to points not described in the second embodiment. In the second embodiment, the same components as those in the first embodiment are assigned the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

[0057] As shown in FIG. 7, the sanitary washing device 5A of the second embodiment has a pair of washing nozzles 51 that can move forward and backward, a shutter unit 52A that opens and closes the front opening 415 (opening) of the washing nozzles 51, and a shutter washing unit 6A.

[0058] Similar to the shutter unit 52 of the first embodiment, the shutter unit 52A is disposed at the center in the left-right direction X on the front side Y1 of the functional unit 4. The shutter unit 52A is formed in a plate shape extending in the left-right direction X (lateral direction) of the toilet bowl 21. The shutter unit 52A is attached to the base plate front surface 411 of the base plate 41 of the functional unit 4 so as to be rotatable around the rotation axis J.

[0059] 7, when the shutter portion 52A is in the closed position, it extends in a flat plane with a downward slope from the front side Y1 to the rear side Y2. The front side of the upper end of the shutter portion 52A is formed in a curved surface that is slightly tapered.

[0060] The shutter cleaning unit 6A cleans the front surface 55a and back surface 55b of the shutter unit 52A when the shutter unit 52A closes the front opening 415. The shutter cleaning unit 6A is disposed diagonally above and in front of the upper end of the shutter unit 52A. When the shutter unit 52A is in the closed position where the front opening 415 is closed, the shutter cleaning unit 6A sprays cleaning water diagonally downward and behind.

[0061] As shown in FIG. 7, the shutter cleaning section 6A has a front cleaning water-spouting section 65 (first water-spouting section) and a back cleaning water-spouting section 66 (second water-spouting section).

[0062] The front flushing water discharger 65 has multiple front flushing outlets 651. The multiple front flushing outlets 651 discharge flushing water onto the front surface 55a of the shutter section 52A. The back flushing water discharger 66 has multiple back surface flushing outlets 661. The multiple back surface flushing outlets 661 discharge flushing water onto the back surface 55b of the shutter section 52A.

[0063] The front flushing water discharger 65 and the back flushing water discharger 66 discharge flushing water that is temporarily stored in the flushing water storage section 67. The flushing water storage section 67 is located inside the cover member 42, at the top of the front part of the functional section 4. The inclined lower surface 672 of the flushing water storage section 67 slopes from the bottom to the top as it moves from the front side Y1 to the rear side Y2, and extends in the left-right direction X.

[0064] A plurality of front face water outlets 651 of the front face cleaning water outlet section 65 and a plurality of back face water outlets 661 of the back face cleaning water outlet section 66 are formed on the inclined lower surface 672 of the cleaning water storage section 67. Cleansing water temporarily stored in the cleaning water storage section 67 is discharged by the plurality of front face water outlets 651 of the front face cleaning water outlet section 65 and the plurality of back face water outlets 661 of the back face cleaning water outlet section 66 towards the shutter section 52A.

[0065] The multiple front water discharge ports 651 are formed by through-holes that penetrate, at an angle diagonally downward and rearward, through the sloping lower surface 672 of the flush water storage section 67, on the front side Y1 of the sloping lower surface 672 of the flush water storage section 67. The multiple front water discharge ports 651 open diagonally downward and rearward so that flush water flows along the front surface 55a of the shutter section 52A when the shutter section 52A is in the closed position.

[0066] The multiple front water outlets 651 open diagonally upward in front of the shutter section 52A, facing diagonally downward and rearward, that is, in a direction along the front surface 55a. As a result, the wash water discharged from the multiple front water outlets 651 flows along the front surface 55a of the shutter section 52A, thereby cleaning the front surface 55a of the shutter section 52A.

[0067] The multiple rear surface water outlets 661 are arranged on the rear side Y2 of the multiple front surface water outlets 651 on the sloping lower surface 672 of the flush water storage section 67. The multiple rear surface water outlets 661 are formed by through-holes that penetrate the sloping lower surface 672 of the flush water storage section 67 at an angle obliquely downward and rearward. The multiple rear surface water outlets 661 open obliquely downward and rearward so that flush water flows along the back surface 55b of the shutter section 52A when the shutter section 52A is in the closed position.

[0068] The multiple rear surface water outlets 661 open diagonally upward in front of the shutter section 52A, facing diagonally downward in the rear, that is, in a direction along the back surface 55b of the shutter section 52A. As a result, the wash water discharged from the multiple rear surface water outlets 661 flows along the back surface 55b of the shutter section 52A, thereby cleaning the back surface 55b of the shutter section 52A.

[0069] In the shutter cleaning unit 6A described above, the front cleaning water discharger 65 and the back cleaning water discharger 66 discharge the cleaning water stored in the cleaning water storage unit 67 downward at the same time when the shutter unit 52A is closed. This allows the shutter cleaning unit 6A to simultaneously clean the front surface 55a and the back surface 55b of the shutter unit 52A.

[0070] In addition to achieving the same effects as the first embodiment, the second embodiment also achieves the following effects. In the second embodiment, the shutter cleaning unit 6A discharges cleaning water diagonally downward and rearward. Therefore, compared to when cleaning water is discharged directly downward, the water is discharged diagonally downward and rearward, which makes it easier for the water to flow onto the front surface 55a and back surface 55b of the shutter unit 52A. This makes it easier to absorb variations in manufacturing and assembly in the positioning of the shutter cleaning unit 6A and the shutter unit 52A. This makes it possible to increase the range in which variations in manufacturing and assembly can be absorbed.

[0071] In this embodiment, even when the shutter section 52A is not attached, the flush water discharged from the shutter flushing section 6A can be made to flow rearward. Therefore, the flush water discharged from the shutter flushing section 6A can be made to flow rearward, rather than toward the water accumulated in the toilet bowl 21. As a result, even when the shutter section 52A is not attached, the flush water can be made to flow rearward, so the user is less likely to feel uncomfortable.

[0072] Although the preferred embodiments of the present disclosure have been described, the present disclosure is not limited to the above-described embodiments and can be modified as appropriate.

[0073] In the above-described embodiment, the front surface cleaning water discharger 61 and the back surface cleaning water discharger 62 are configured with a plurality of water discharge ports. However, this is not limiting. The front surface cleaning water discharger 61 and the back surface cleaning water discharger 62 may be configured as slits that open and extend in the left-right direction X.

[0074] There are no limitations on the orientation of the multiple front water outlets 611 and the multiple rear water outlets 621. For example, the multiple front water outlets 611 and the multiple rear water outlets 621 may discharge flush water directly downward, diagonally rearward, or horizontally rearward.

[0075] In the above embodiment, the protrusion 413a is provided on the front surface of the functional part 4. However, this is not limitative. The protrusion may be provided on the rear surface 52b of the shutter part 52.

[0076] In the above embodiment, the shutter unit is configured to open and close the opening formed in front of the cleaning nozzle. However, this is not limited to this. The shutter unit may be configured to open and close the opening formed in front of, for example, a warm air dryer, a deodorizing device, a toilet flushing water discharger, a mist nozzle, or a foam nozzle.
