[0011] Hereinafter, a toilet device according to an embodiment will be described with reference to the drawings. Each figure described in the following embodiment is a schematic diagram, and the size and thickness ratio of each component do not necessarily reflect the actual dimensional ratio. In addition, the configuration described in the following embodiment is merely an example of the present disclosure. The present disclosure is not limited to the following embodiment, and various modifications are possible depending on the design, etc., as long as the effects of the present disclosure can be achieved.

[0012] (First embodiment) (1) Overall configuration of the toilet The toilet apparatus 1 will be described with reference to Figures 1 to 7. The toilet apparatus 1 comprises a bowl 2 and a toilet seat apparatus 3 installed on an upper portion of the bowl 2.

[0013] The bowl 2 is a generally funnel-shaped toilet bowl for receiving waste. The bowl 2 is connected to a sewer pipe via a drain outlet provided at the bottom and a trap or the like. The bowl 2 is made of, for example, resin and has a hollow shape.

[0014] 2 to 6, bowl 2 has rim 20 that is annular in plan view. Upper surface 21 of rim 20 is a generally annular flat surface. Bowl 2 has an annular outer frame portion 22 that is located on the outer periphery of rim 20 of bowl 2.

[0015] 1, the toilet seat device 3 has a main body 6 disposed behind the bowl 2, a toilet seat 4 rotatably supported by the main body 6, and a toilet lid 5 rotatably supported by the main body 6. The toilet seat 4 and the toilet lid 5 are raised from or lowered to the upper surface of the bowl 2 either manually or electrically. The main body 6 accommodates, for example, a private parts cleansing device, a drying device, and a deodorizing device, all of which are not shown.

[0016] The toilet seat 4 is made of, for example, resin. The toilet seat 4 has a central opening 40 formed to be annular as a whole. The toilet seat 4 is rotatable between a closed state (i.e., a lowered state) and an open state (i.e., a raised state). In the closed state, the toilet seat 4 is disposed on the bowl 2 so as to surround the outer edge of the bowl 2, exposing the bowl 2 through the central opening 40. This allows a user to excrete into the bowl 2 while sitting on the toilet seat 4. The toilet seat 4 has an upper surface 41 (i.e., the front surface) and a lower surface 42 (i.e., the back surface).

[0017] As shown in Figures 5 and 6, when toilet seat 4 is down, upper surface 41 is the surface on which a user sits, and lower surface 42 closely faces upper surface 21 of bowl 2. More specifically, a gap 31 is provided between the outer periphery of lower surface 42 and upper surface 21 of bowl 2. Outer frame portion 22 of bowl 2 is located on the outer periphery between upper surface 21 of rim 20 of bowl 2 and lower surface 42 of toilet seat 4. The height of outer frame portion 22 is such that the upper surface heights are the same when toilet seat 4 is closed, as shown in Figure 2.

[0018] The toilet lid 5 is made of, for example, resin. The toilet lid 5 is rotatable between a closed state (i.e., a lowered state) and an open state (i.e., a raised state). When closed, the toilet lid 5 covers the toilet seat 4 from above.

[0019] In this specification, "front," "rear," "left," and "right" are directions seen from a user sitting on the toilet seat 4 with their back to the open toilet lid 5.

[0020] (2) Cleansing water discharge device The toilet bowl apparatus 1 further comprises a flush water discharge device 7. The flush water discharge device 7 is a device for cleaning the underside 42 of the toilet seat 4.

[0021] (2-1) Basic configuration of the flushing water discharge device As shown in Figures 3 to 7, flush water discharge device 7 has piping 71 provided inside bowl 2, and flush water discharge outlet 72 located at the tip of piping 71. Flush water W1 supplied from tank 77 is guided through piping 71 to flush water discharge outlet 72. Flush water W1 is discharged from flush water discharge outlet 72 towards the upper surface 21 of bowl 2 and the underside 42 of toilet seat 4.

[0022] With the above configuration and operation, the upper surface 21 of the bowl 2 and the underside 42 of the toilet seat 4 are cleaned with flush water W1. Furthermore, because the piping 71 is provided inside the bowl 2, the structure of the supply path that supplies the flush water W1 is simplified. The flush water W1 is, for example, tap water.

[0023] Furthermore, the outer frame portion 22 prevents the flush water W1 flowing through the gap 31 between the upper surface 21 of the bowl 2 and the underside 42 of the toilet seat 4 from spilling out to the outside of the toilet apparatus 1. As a result, stains caused by the flush water W1 are less likely to occur in the toilet space in which the toilet apparatus 1 is placed.

[0024] (2-2) Detailed configuration of the washing water discharge device 4, the flush water outlet 72 comprises a plurality of flush water outlets 72A-72H (for example, a first flush water outlet 72A, a second flush water outlet 72B, a third flush water outlet 72C, a fourth flush water outlet 72D, a fifth flush water outlet 72E, a sixth flush water outlet 72F, a seventh flush water outlet 72G, and an eighth flush water outlet 72H) arranged to surround the upper surface 21 of the bowl 2. With the above configuration, flush water W1 is discharged from the plurality of flush water outlets 72A-72H, so that the upper surface 21 of the bowl 2 and the underside 42 of the toilet seat 4 are washed over the entire area in the direction extending in an annular shape.

[0025] Specifically, the nozzles at the ends of the pipes 71 are disposed within the outer frame portion 22 of the bowl 2, and the flush water outlets 72A-72H are disposed as openings of the nozzles on the inner peripheral surface of the outer frame portion 22. More specifically, as shown in FIG. 4, the flush water outlets 72A-72H are oriented in the direction in which flush water W1 flows through the gap 31 between the upper surface 21 of the bowl 2 and the lower surface 42 of the toilet seat 4, from the front portion 81 of the upper surface 21 of the bowl 2 and the front portion 82 of the toilet seat 4. Specifically, the flush water outlets 72A-72H are oriented obliquely toward the rear side of the gap 31 and the inside of the bowl 2. With the above configuration, as shown by the outlined arrow W2 in FIG. 4, part of the flush water W1 flows through the gap 31 between the upper surface 21 of the bowl 2 and the lower surface 42 of the toilet seat 4, from the front portion 81 of the bowl 2 and the front portion 82 of the toilet seat 4. Because the flow of flush water W1 is unidirectional in this way, problems such as dirt remaining on the upper surface 21 of bowl 2 or the underside 42 of toilet seat 4 are unlikely to occur.

[0026] Here, as shown in Fig. 4, on the right side of Fig. 4, a first cleaning water outlet 72A, a third cleaning water outlet 72C, a fifth cleaning water outlet 72E, and a seventh cleaning water outlet 72G are arranged in this order from the front part 81 toward the rear part 82. On the left side of Fig. 4, a second cleaning water outlet 72B, a fourth cleaning water outlet 72D, a sixth cleaning water outlet 72F, and an eighth cleaning water outlet 72H are arranged in this order from the front part 81 toward the rear part 82. As a result of the above, the first cleaning water outlet 72A and the second cleaning water outlet 72B form a first set, the third cleaning water outlet 72C and the fourth cleaning water outlet 72D form a second set, the fifth cleaning water outlet 72E and the sixth cleaning water outlet 72F form a third set, and the seventh cleaning water outlet 72G and the eighth cleaning water outlet 72H form a fourth set, and the first cleaning water outlet 72A to the eighth cleaning water outlet 72H are arranged in this order from the front part 81 to the rear part 82.

[0027] As shown in Figs. 3, 4, and 7, the main body 6 is provided with a guide 8 arranged in the rear portion 82 in the gap 31 between the upper surface 21 of the bowl 2 and the lower surface 42 of the toilet seat 4. The guide 8 has a structure that guides the flush water W1 that flows from the front portion 81 to the rear portion 82 in the gap 31 between the upper surface 21 of the bowl 2 and the lower surface 42 of the toilet seat 4 into the bowl 2 (that is, prevents the flush water W1 from moving outside the bowl 2). Specifically, as shown in Figs. 3 and 4, the guide 8 is a wall surface located on the rear side of the first portion 821 and the second portion 822 of the rear portion 82. The guide 8 is smoothly curved in a concave shape in a plan view. Therefore, the first portion 821 and the second portion 822 of the rear portion 82 extend so that their widths gradually narrow toward the center in the left-right direction. At the center in the left-right direction of the guide 8, the widths of the first portion 821 and the second portion 822 of the rear portion 82 are zero.

[0028] According to this embodiment, flush water W1 flowing from the front portion 81 towards the rear portion 82 is guided into the bowl 2 by the guide 8. The flush water W1 is therefore prevented from splashing out to the outside of the toilet apparatus 1. As a result, stains caused by the flush water W1 are less likely to occur in the toilet space in which the toilet apparatus 1 is placed.

[0029] 8, the cleaning water discharge device 7 further includes a cleaning water supply device 73. The cleaning water supply device 73 supplies cleaning water W1 to the pipe 71.

[0030] First, a detailed structure of the pipe 71 will be described. As shown in Fig. 7 and Fig. 8, the pipe 71 has a plurality of pipes 71A to 71H (a first pipe 71A, a second pipe 71B, a third pipe 71C, a fourth pipe 71D, a fifth pipe 71E, a sixth pipe 71F, a seventh pipe 71G, and an eighth pipe 71H). The first pipe 71A, the second pipe 71B, the third pipe 71C, the fourth pipe 71D, the fifth pipe 71E, the sixth pipe 71F, the seventh pipe 71G, and the eighth pipe 71H are connected to the first cleaning water outlet 72A, the second cleaning water outlet 72B, the third cleaning water outlet 72C, the fourth cleaning water outlet 72D, the fifth cleaning water outlet 72E, the sixth cleaning water outlet 72F, the seventh cleaning water outlet 72G, and the eighth cleaning water outlet 72H, respectively. The multiple pipes 71A to 71H are connected to a pump 76 via a common pipe 78. The first pipe 71A, the second pipe 71B, the third pipe 71C, the fourth pipe 71D, the fifth pipe 71E, the sixth pipe 71F, the seventh pipe 71G, and the eighth pipe 71H are provided with a first valve 79A, a second valve 79B, a third valve 79C, a fourth valve 79D, a fifth valve 79E, a sixth valve 79F, a seventh valve 79G, and an eighth valve 79H, respectively. Each of the valves 79A to 79H is an electromagnetic valve that can be opened and closed. Each of the valves 79A to 79H controls the supply of cleaning water W1 based on a command from a control unit 74 described later.

[0031] The pump 76 is connected to a tank 77 as shown in FIG.

[0032] (2-3) Control configuration of the cleaning water discharge device As shown in Fig. 8, the wash water discharge device 7 further has a control unit 74. The control unit 74 includes a computer system having one or more processors and a memory. The functions of the control unit 74 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided via a telecommunications line such as the Internet, or may be recorded and provided on a non-transitory recording medium such as a memory card.

[0033] The control unit 74 controls the operation of the flush water supply device 73. Specifically, the control unit 74 controls the flush water supply device 73 so that the flush water discharge from the multiple flush water discharge ports 72A-72H can be changed individually. More specifically, the control unit 74 controls the pump 76 and multiple valves 79A-79H. With the above configuration, the flush water discharge from the multiple flush water discharge ports 72A-72H can be changed individually, so that the flush water discharge and stopping or the discharge amount from the multiple flush water discharge ports 72A-72H can be changed as necessary. As a result, efficient flushing is possible.

[0034] An operation signal is input to the control unit 74 from the operation unit 75. The operation unit 75 is, for example, a remote control having switches or buttons. The operation unit 75 accepts operation instructions input from a user, and inputs an operation signal based on the input operation instructions to the control unit 74. The control unit 74 controls the operation of each part of the toilet device 1 based on the operation signal.

[0035] (2-4) Control operation of the flushing water discharge device The control unit 74 controls the wash water supply device 73 so that the wash water outlets 72A to 72H start discharging wash water in sequence from the front side to the rear side.

[0036] The control operation of the washing water discharge device 7 will be described below with reference to FIG.

[0037] The control flow charts described below are merely examples, and each step may be omitted or replaced as necessary. In addition, a plurality of steps may be executed simultaneously, or some or all of the steps may be executed in an overlapping manner.

[0038] Furthermore, each block in the control flowchart is not limited to a single control operation, but can be replaced with a plurality of control operations represented by a plurality of blocks.

[0039] The operation of each device is the result of commands from the control unit 74 to each device, and these are represented by each step of the software application.

[0040] In step S1, the control unit 74 waits for an operation signal to be input from the operation unit 75. In this initial state, the pump 76 is stopped and the multiple valves 79A to 79H are closed. When an operation signal is input, the process proceeds to step S2.

[0041] In step S2, the control section 74 drives the pump 76 and opens the first valve 79A and the second valve. This causes flush water W1 to be discharged from the first pair of first flush water outlet 72A and second flush water outlet 72B. As shown in Figures 5 to 7, flush water W1 flows towards the gap 31 and hits the underside 42 of the toilet seat 4 and the upper surface 21 of the bowl 2. Part of the flush water W1 flows into the bowl 2. As shown by the outlined arrow W2 in Figure 4, the remainder of the flush water W1 flows rearward through the gap 31.

[0042] In step S3, the control section 74 opens the third valve 79C and the fourth valve 79D after a predetermined time has elapsed. This causes flush water W1 to be discharged from the second pair of the third flush water outlet 72C and the fourth flush water outlet 72D. The flush water W1 flows towards the gap 31 as shown in Figures 5 to 7, and hits the underside 42 of the toilet seat 4 and the upper surface 21 of the bowl 2. Part of the flush water W1 flows into the bowl 2. As shown by the outlined arrow W2 in Figure 4, the remainder of the flush water W1 flows rearward through the gap 31.

[0043] In step S4, the control section 74 opens the fifth valve 79E and the sixth valve 79F after a predetermined time has elapsed. This causes flush water W1 to be discharged from the third pair of the fifth flush water outlet 72E and the sixth flush water outlet 72F. The flush water W1 flows towards the gap 31 as shown in Figures 5 to 7, and hits the underside 42 of the toilet seat 4 and the upper surface 21 of the bowl 2. Part of the flush water W1 flows into the bowl 2. As shown by the outlined arrow W2 in Figure 4, the remainder of the flush water W1 flows rearward through the gap 31.

[0044] In step S5, the control section 74 opens the seventh valve 79G and the eighth valve 79H after a predetermined time has elapsed. This causes flush water W1 to be discharged from the fourth pair of the seventh flush water outlet 72G and the eighth flush water outlet 72H. The flush water W1 flows towards the gap 31 as shown in Figures 5 to 7, and hits the underside 42 of the toilet seat 4 and the upper surface 21 of the bowl 2. Part of the flush water W1 flows into the bowl 2. As shown by the outlined arrow W2 in Figure 4, the remainder of the flush water W1 flows rearward through the gap 31.

[0045] In step S6, the process waits for a predetermined time to elapse, and if the predetermined time has elapsed, the process proceeds to step S7.

[0046] In step S7, the control unit 74 stops the pump 76 and closes the valves 79A to 79H, whereupon the process ends.

[0047] As a result of the above, the underside 42 of the toilet seat 4 and the upper surface 21 of the bowl 2 are cleaned with the cleaning water W1.

[0048] In particular, since the cleaning water W1 flows from the front side to the rear side within the gap 31, cleaning is performed efficiently.

[0049] In particular, because the flush water W1 is discharged sequentially from the front to the rear, the flow of the flush water W1 from the front to the rear is not impeded. Also, with this configuration, dirt on the front side is carried to the rear by the flush water W1. Therefore, dirt on the upper surface 21 of the bowl 2 and the underside 42 of the toilet seat 4 is less likely to remain on the front side.

[0050] (Modification) The above-described embodiment is merely one of various embodiments of the present disclosure. The above-described embodiment can be modified in various ways depending on the design and the like as long as the object of the present disclosure can be achieved. Below, modifications of the above-described embodiment are listed. The modifications described below can be applied in appropriate combination.

[0051] The wash water may contain a detergent.

[0052] A drying device may be provided for drying the wash water.

[0053] The number, position and orientation of the cleaning water outlets 72 in a plan view are not particularly limited.

[0054] The shape and length of the outer frame of the bowl 2 are not particularly limited.

[0055] The shape of the guide 8 is not particularly limited. The guide 8 may be a part of the toilet seat 4.

[0056] The cleaning water W1 may be discharged from all the cleaning water discharge ports 72 at the same time, and then the discharge of the cleaning water W1 may be stopped at the same time.

[0057] The timing for ending ejection from the front ejection port may occur while ejection from the rear ejection port is in progress.

[0058] The operation of the flush water discharge device 7 may be performed automatically. For example, the operation of the flush water discharge device 7 may be performed periodically, or may be performed a predetermined time after the user leaves the toilet device 1.

[0059] The structure of the water circuit is not particularly limited, that is, the configuration of the cleaning water supply flow path and the arrangement of the valves 79A to 79H are not limited to those in the above embodiment.

[0060] (Aspect) The present specification discloses the following aspects.

[0061] The toilet bowl device (1) according to the first aspect comprises a bowl (2), a toilet seat (4), and a flush water discharge device (7). The toilet seat (4) is provided above the bowl (2). The flush water discharge device (7) has piping (71) and at least one flush water discharge outlet (72). The piping (71) is provided inside the bowl (2). The at least one flush water discharge outlet (72) is located at the tip of the piping (71), and discharges flush water (W1) toward the upper surface (21) of the bowl (2) and the underside (42) of the toilet seat (4).

[0062] According to this embodiment, the upper surface (21) of the bowl (2) and the underside (42) of the toilet seat (4) are cleaned with the cleaning water (W1). Furthermore, because the piping (71) is provided inside the bowl (2), the structure of the supply path for supplying the cleaning water (W1) is simplified.

[0063] In the toilet device (1) of the second aspect, in the first aspect, the bowl (2) further has an outer frame portion (22) located on the outer periphery between the upper surface (21) of the bowl (2) and the lower surface (42) of the toilet seat (4).

[0064] According to this embodiment, the outer frame portion (22) prevents the flush water (W1) flowing between the upper surface (21) of the bowl (2) and the lower surface (42) of the toilet seat (4) from splashing out to the outside of the toilet apparatus (1). As a result, stains caused by the flush water (W1) are less likely to occur in the toilet space in which the toilet apparatus (1) is placed.

[0065] In the toilet apparatus (1) according to the third aspect, in the first or second aspect, at least one flush water outlet (72) has a plurality of outlets (72A-72H) arranged to surround the upper surface (21) of the bowl (2).

[0066] According to this embodiment, the wash water (W1) is discharged from a plurality of discharge ports (72A-72H), so that the upper surface (21) of the bowl (2) and the lower surface (42) of the toilet seat (4) are washed over their entirety in the direction in which they extend in an annular shape.

[0067] In the toilet apparatus (1) of the fourth aspect, in the third aspect, the multiple discharge ports (72A-72H) are oriented so that flush water (W1) flows between the upper surface (21) of the bowl (2) and the underside (42) of the toilet seat (4) from the front portion (81) to the rear portion (82) of the bowl (2) and the toilet seat (4).

[0068] According to this embodiment, a portion of the flush water (W1) flows between the upper surface (21) of the bowl (2) and the underside (42) of the toilet seat (4) from the front portion (81) to the rear portion (82) of the bowl (2) and the toilet seat (4). Because the flow of the flush water (W1) is unidirectional in this manner, problems such as dirt on the upper surface (21) of the bowl (2) or the underside (42) of the toilet seat (4) remaining in one place are unlikely to occur.

[0069] The toilet bowl apparatus (1) according to the fifth aspect is the same as the toilet bowl apparatus (1) according to the fourth aspect, and further includes a guide (8). The guide (8) is disposed in the rear portion (82) between the upper surface (21) of the bowl (2) and the lower surface (42) of the toilet seat (4), and guides flush water (W1) that flows between the upper surface (21) of the bowl (2) and the lower surface (42) of the toilet seat (4) from the front portion (81) toward the rear portion (82) into the bowl (2).

[0070] According to this embodiment, flush water (W1) flowing from the front portion (81) toward the rear portion (82) is guided into the bowl (2) by the guide (8). Therefore, the flush water (W1) is prevented from splashing out to the outside of the toilet device (1). As a result, the toilet space in which the toilet device (1) is placed is less likely to become soiled by flush water.

[0071] In the toilet apparatus (1) according to a sixth aspect, in any of the third to fifth aspects, the flush water discharge device (7) further includes a flush water supply device (73) and a control unit (74). The flush water supply device (73) supplies flush water (W1) to the pipe (71). The control unit (74) controls the operation of the flush water supply device (73). The control unit (74) controls the flush water supply device (73) so as to be able to individually change the discharge of flush water from the multiple discharge ports (72A-72H).

[0072] According to this aspect, the cleaning water discharge from the multiple outlets (72A to 72H) can be changed individually, so that efficient cleaning can be achieved by varying the water discharge and stopping or the discharge amount from the multiple outlets (72A to 72H) as needed.

[0073] In the toilet bowl apparatus (1) according to the seventh aspect, in the sixth aspect, the control section (74) controls the flush water supply device (73) so that the multiple discharge ports (72A-72H) start discharging flush water in sequence from the front side to the rear side.

[0074] According to this embodiment, dirt on the front side is sent to the rear side by the flush water (W1), so dirt on the upper surface (21) of the bowl (2) and the underside (42) of the toilet seat (4) is less likely to remain on the front side. [Explanation of symbols]
