[0003] [Patent Document 1] JP 2019-173287 A Summary of the Invention [Problem to be solved by the invention]

[0004] The shutter section of Patent Document 1 opens and closes the front opening of the cleaning nozzle by moving. Therefore, if the shutter cleaning section having a water outlet is provided on the upper part of the movable shutter section, the structure of the shutter section becomes complicated. Therefore, there is a demand for a simple shutter section.

[0005] The present disclosure aims to provide a sanitary washing device that includes a shutter section that opens and closes an opening, and a shutter washing section that can wash the front surface of the shutter section, and that allows the shutter section to be easily configured. [Means for solving the problem]

[0006] The present disclosure relates to a sanitary cleaning device comprising a shutter section that opens and closes an opening formed in a functional section, and a shutter cleaning section that is arranged above the shutter section and cleans the front surface of the shutter section while the shutter section closes the opening.

[0008] The 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 is the front side as viewed from 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 is the left-to-right direction. In the left-to-right direction X, the left side is the left side X1, and the right side is the right side X2, as viewed from a user seated on the toilet seat 22. The up-to-down direction Z is the vertical direction relative to the floor surface on which the toilet 21 is installed. In the up-to-down direction Z, the upper side is Z1, and the lower side is Z2. The cross section shown in FIG. 5 is a cross section cut along the front-to-back direction Y and the up-to-down direction Z at the line AA shown in FIG. 2, viewed in the left-to-right direction X.

[0009] As shown in Fig. 1, the toilet device 1 according to this embodiment includes 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] The functional unit 4 is disposed above the rear part of the toilet bowl 21, as shown in Fig. 1. The functional unit 4 includes at least a sanitary washing device 5 that washes the private parts of the user, as shown in Figs. 2 and 3. The functional unit 4 includes functional parts 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 parts of the functional unit 4 are disposed on the base plate 41.

[0012] The functional parts are installed on the base plate 41 or at other installation positions, taking into consideration various functions and their positional relationships with other components. 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 washes the user's private parts, a hose, a power supply unit, a control circuit board, an electric opening / 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 advance and retreat, a shutter part 52 that opens and closes a front opening 415 (opening) of the washing nozzles 51, and a shutter washing part 6. The front opening 415 is formed on the front side Y1 of the functional part 4.

[0014] The pair of cleaning nozzles 51 are disposed at a distance from each other in the left-right direction X at the center in the left-right direction X on the front side Y1 of the functional part 4. The pair of cleaning nozzles 51 are used for anal washing and bidet washing to wash private parts of the human body. The cleaning nozzle 51 spouts cleaning water toward the human body from a nozzle spout (not shown) provided at the upper part on the tip side.

[0015] 2 and 4, the shutter portion 52 is disposed at the center in the left-right direction X on the front side Y1 of the functional portion 4. The shutter portion 52 is formed in a plate shape 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 curved in an arc shape such that the center in the left-right direction X is located at the lowest position and that it 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 smooth curved surface 414, and is formed in a flat shape with a downward inclination that descends 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 section 52 is in the closed position, it is disposed along the base plate front surface 411 so as to cover a part of the upper side of the base plate front surface 411, which is the front surface of the functional section 4. In the range of the left-right direction X in which the shutter section 52 is disposed, a part of the upper side of the base plate front surface 411 is covered by the shutter section 52. A lower part of the base plate front surface 411 that is not covered by the shutter section 52 is exposed to the front side Y1.

[0020] 5, the shutter section 52 has an upper end bent portion 521 and an inclined flat surface portion 522. When the shutter section 52 is in the closed position, the upper end bent portion 521 bulges slightly toward the front side Y1 and extends in the up-down direction Z. When the shutter section 52 is in the closed position, the inclined flat surface portion 522 extends in a flat shape with a downward inclination from the lower end of the upper end bent portion 521 toward the front side Y1 toward 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 with respect to the inclined flat 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 portion 522, which extends downwardly, rearward from an imaginary extension line K that linearly extends the inclined flat portion 522 to the upper side Z1.

[0022] 3 and 5, the shutter section 52 has a pair of protruding support parts 53 protruding rearward from an upper side of the back surface 52b. The protruding support parts 53 have a cylindrical support shaft 531 extending in the left-right direction X. The support shaft 531 is rotatably attached to a pair of C-shaped release locking parts 412a 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 section 52 is rotatable about a rotation axis J extending in the left-right direction X of the support shaft 531.

[0023] In this embodiment, the upper end of the shutter section 52 is formed to bend backward. For example, when the shutter section 52 rotates from the closed position to the open position, if the entire shutter section 52 were formed in a straight line up to the upper end, the radius of the rotation trajectory of the upper end of the shutter section 52 would be large. 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, in the present disclosure, because the upper end of the shutter section 52 is bent rearward, when the shutter section 52 is opened, the gap that accommodates the upper end of the shutter section 52 can be made smaller than when the shutter section 52 is formed in a straight line up to its 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 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 in and out 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 disposed so as 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 located in the closed position, the shutter section 52 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 disposed apart from each other in the left-right direction X is formed on the lower inclined surface 413 of the base plate front surface 411 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 base plate front surface 411. Cleaning water that is discharged from a 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 the back surface 52b of the shutter unit 52 when the shutter unit 52 has the front opening 415 closed. The shutter cleaning unit 6 is disposed above the upper end portion of the shutter unit 52. The shutter cleaning unit 6 spouts cleaning water downward onto the shutter unit 52 when the shutter unit 52 is in the closed position with the front opening 415 closed.

[0030] In this embodiment, "a state in which the shutter portion 52 closes the front opening 415" or "when the shutter portion 52 is located at the closed position in which the front opening 415 is closed" does not mean that the shutter portion 52 completely closes the front opening 415. "A state in which the shutter portion 52 closes the front opening 415" or "when the shutter portion 52 is located at the closed position in which the front opening 415 is closed" also includes a state in which the shutter portion 52 almost blocks the front opening 415 when the shutter portion 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 spouting section 61 (first water spouting section) and a back cleaning water spouting section 62 (second water spouting section).

[0032] 3 and 4, the front cleaning water discharge section 61 has multiple front water discharge ports 611. The multiple front water discharge ports 611 discharge cleaning water onto the front surface 52a of the shutter section 52. The back surface cleaning water discharge section 62 has multiple back surface water discharge ports 621. The multiple back surface water discharge ports 621 discharge cleaning water onto the back surface 52b of the shutter section 52.

[0033] The front cleaning water ejection section 61 and the back cleaning water ejection section 62 eject cleaning water that is temporarily stored in the cleaning water storage section 63. As shown in Figures 2, 4 and 5, the cleaning water storage section 63 is disposed inside the cover member 42, at the upper part of the front part of the functional section 4. The cleaning water storage section 63 is formed in a hollow shape extending in the left-right direction X. The lower surface 632 of the cleaning 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 surface water outlets 611 of the front surface cleaning water outlet 61 and a plurality of back surface water outlets 621 of the back surface cleaning 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 both ends of the flush water storage section 63 in the left-right direction X, as shown in Figs. 4 and 5. The 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 toward the shutter section 52 by the plurality of front surface water outlets 611 of the front surface cleaning water outlet 61 and the plurality of back surface water outlets 621 of the back surface cleaning water outlet 62.

[0035] The multiple front water outlets 611 and the multiple back 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 Figures 5 and 6. 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 back water outlets 621 are arranged on the rear side Y2. The multiple front water outlets 611 and the multiple back 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] The multiple front water outlets 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 Fig. 3. The multiple front water outlets 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, as shown in Fig. 5.

[0037] The multiple front water outlets 611 open above the surface 521a of the front side Y1 of the upper end 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 end bent portion 521. As a result, 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 end 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 Fig. 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 the rear side Y2 of the multiple front surface water outlets 611 of the underside 632 of the flush water storage section 63. As shown in Fig. 5, the multiple rear surface water outlets 621 open downwards so as to flow flush water along the rear 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, which is 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 wash 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 outlets 621 flows along the rear surface 52b of the shutter section 52, and then flows along the base plate front surface 411 of the functional section 4. This allows the shutter cleaning section 6 to clean the base plate front surface 411 of the functional section 4 with the cleaning water discharged from the multiple rear surface water outlets 621.

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

[0042] 5, with the shutter section 52 closed, the front cleaning water discharge section 61 discharges cleaning water downward from multiple front water discharge ports 611, thereby discharging cleaning water onto the surface 521a of the front side Y1 of the upper end bent section 521 of the shutter section 52. The cleaning water discharged onto the surface 521a of the front side Y1 of the upper end bent section 521 of the shutter section 52 flows along the front surface 52a of the shutter section 52.

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

[0044] 5, with the shutter section 52 closed, the back surface cleaning water discharge section 62 discharges cleaning water downward from a plurality of back surface water discharge ports 621, thereby discharging cleaning water onto the surface 521b of the rear side Y2 of the upper end bent section 521 of the shutter section 52. The cleaning water discharged onto the surface 521b of the rear side Y2 of the upper end bent section 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 base plate front surface 411 of the functional section 4, and flows along the lower part of the lower inclined surface 413 of the base plate front surface 411 due to the surface tension of the water. 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 base plate front surface 411 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 a timing before the cleaning nozzle 51 performs a cleaning operation of cleaning a local part of the human body as long as the shutter unit 52 is in a closed state, and may be a timing after the cleaning nozzle 51 completes a cleaning operation of cleaning a local part of the human body, or may be 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 advantages.

[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 separate from the shutter section 52 can be provided above the shutter section 52, which is a movable section. This allows cleaning by the shutter cleaning section 6 separate from the shutter section 52. This allows the shutter section 52 to 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. This prevents cleaning water discharged from the shutter cleaning section 6 from splashing onto the front side Y1 of the toilet bowl 21.

[0050] In the present embodiment, the shutter cleaning unit 6 is capable of cleaning the back surface 52b of the shutter unit 52 while the shutter unit 52 is in a state in which the front opening 415 is closed. 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 the present 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 in which 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 period of time.

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

[0053] In this embodiment, the shutter cleaning unit 6 discharges cleaning water downward. As a result, the shutter unit 52 is disposed below the shutter cleaning unit 6, so that cleaning water can be discharged in the direction of gravity. Therefore, the shutter unit 52 can be easily cleaned.

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

[0055] In this embodiment, the shutter section 52 is disposed along the base plate front surface 411 so as to cover a part of the base plate front surface 411 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 base plate front surface 411 of the functional section 4. This allows the back surface cleaning water discharge section 62 to clean the back surface 52b of the shutter section 52 and also clean the lower part of the base plate front surface 411 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 the points not described in the second embodiment. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

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

[0058] Similar to the shutter unit 52 in 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 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 about the rotation axis J.

[0059] 7, when the shutter portion 52A is in the closed position, it extends in a plane with a downward inclination 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 shape that is inclined so that the upper end side 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 portion 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 cleaning water spouting section 65 has multiple front water spouting ports 651. The multiple front water spouting ports 651 spout cleaning water onto the front surface 55a of the shutter section 52A. The back surface cleaning water spouting section 66 has multiple back surface water spouting ports 661. The multiple back surface water spouting ports 661 spout cleaning water onto the back surface 55b of the shutter section 52A.

[0063] The front cleaning water discharger 65 and the back cleaning water discharger 66 discharge cleaning water that is temporarily stored in the cleaning water storage section 67. The cleaning water storage section 67 is disposed inside the cover member 42, at the upper part of the front part of the functional part 4. The inclined lower surface 672 of the cleaning water storage section 67 slopes from the lower side to the upper side 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 surface outlets 651 of the front surface cleaning water spouting section 65 and a plurality of back surface outlets 661 of the back surface cleaning water spouting 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 spouted by the plurality of front surface outlets 651 of the front surface cleaning water spouting section 65 and the plurality of back surface outlets 661 of the back surface cleaning water spouting 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, the inclined lower surface 672 of the flush water storage section 67, on the front side Y1 of the inclined lower surface 672 of the flush water storage section 67. The multiple front water discharge ports 651 open diagonally downward and rearward so as to flow flush water 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 obliquely upward in front of the shutter part 52A, facing obliquely downward and rearward 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 part 52A, thereby washing the front surface 55a of the shutter part 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 inclined lower surface 672 of the flush water storage section 67. The multiple rear surface water outlets 661 are formed by through-holes that penetrate, at an angle obliquely downward and rear, the inclined lower surface 672 of the flush water storage section 67. The multiple rear surface water outlets 661 open obliquely downward and rearward so as to flow flush water along the rear surface 55b of the shutter section 52A when the shutter section 52A is in the closed position.

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

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

[0070] According to the second embodiment, in addition to providing the same effects as the first embodiment, the following effects are provided. In the second embodiment, the shutter cleaning section 6A discharges cleaning water diagonally downward and rearward. Therefore, compared to discharging cleaning water directly downward, the water is more likely to flow onto the front surface 55a and rear surface 55b of the shutter section 52A because the cleaning water is discharged diagonally downward and rearward. This makes it easier to absorb manufacturing and assembly variations in the arrangement positions of the shutter cleaning section 6A and the shutter section 52A. Therefore, the range in which manufacturing and assembly variations can be absorbed can be increased.

[0071] In this embodiment, even when the shutter section 52A is not attached, the flush water discharged from the shutter flush section 6A can be made to flow rearward. Therefore, the flush water discharged from the shutter flush section 6A can be made to flow rearward, not in the direction of 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 embodiment, the front cleaning water spouting section 61 and the back cleaning water spouting section 62 are configured with a plurality of water outlets. However, this is not limited thereto. The front cleaning water spouting section 61 and the back cleaning water spouting section 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 back water outlets 621. For example, the multiple front water outlets 611 and the multiple back water outlets 621 may discharge flush water directly downward, may discharge flush water diagonally backward, or may discharge flush water horizontally to the rear side.

[0075] In the embodiment, the protrusion 413a is provided on the front surface of the functional part 4. However, this is not limiting. 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, the present invention is not limited to this. The shutter unit may be configured to open and close the opening formed in front of, for example, a hot air dryer, a deodorizing device, a toilet flushing water discharge unit, a mist nozzle, a foam nozzle, or the like.
