The water supply pipe 22 is provided outside the washing water tank 18, and the water supply pipe 22 has a water supply channel 23. Tap water is supplied to the water supply channel 23 at a predetermined water pressure. The water supply pipe 22 is provided at a position close to the opening 21 in the washing water tank 18.

A ball tap 24 is attached to the water supply pipe 22. The ball tap 24 is provided inside 20 of the washing water tank 18. The ball tap 24 is a mechanism for supplying and stopping the water supplied from the water supply pipe 22 to the inside 20 of the washing water tank 18. The ball tap 24 is an arm operably attached to the ball tap main body 25, the water supply passage 26 provided in the ball tap main body 25, the passage 27 connecting the water supply passage 26 and the water supply passage 23, and the ball tap main body 25 with the support shaft 41 as a fulcrum. 28, a float 29 attached to the arm 28, a link 42 connected to the arm 28, and an operating member 43 connected to the link 42.

The float 29 is, for example, a hollow body made of synthetic resin, copper, stainless steel, or the like. The float 29 floats on the water surface 31 of the washing water 30 stored in the inside 20 of the washing water tank 18. The float 29 is raised, lowered and stopped according to the amount of the washing water 30 in the inside 20 of the washing water tank 18, specifically, the water level of the water surface 31. When the float 29 descends and rises, the arm 28 operates and the actuating member 43 opens and closes the passage 27.

The cleaning pipe 32 is provided outside the cleaning water tank 18, and the cleaning pipe 32 has a cleaning water supply path 13. A mount portion 33 is provided on the bottom portion 65, and a valve body (float rubber) 34 is provided inside 20 of the washing water tank 18. The valve body 34 is made of synthetic rubber and is connected to the arm 35. The arm 35 is operably supported by the mount portion 33 around the support shaft 36. The valve body 34 is pushed in a direction approaching the mount portion 33 by the water pressure inside the washing water tank 18. The mount portion 33 has a drainage channel 37, and the drainage channel 37 is connected to the wash water supply channel 13.

The lever 38 is attached to the side wall 64 of the wash water tank 18. The lever 38 and the water supply pipe 22 are provided at opposite positions in the horizontal direction on the side wall 64. That is, the lever 38 and the water supply pipe 22 are provided at intervals in the horizontal direction. The lever 38 is provided at substantially the same position as the water supply pipe 22, specifically, at a predetermined position in the height direction of the washing water tank 18. The technical meaning of the predetermined position will be described later. The lever 38 is operated by the user and is provided to separate the valve body 34 from the mount portion 33 by an operating force.

The lever 38 is rotatably attached to the washing water tank 18 within a range of a predetermined angle. The lever 38 is arranged on the outside 71 of the washing water tank 18. A rod 39 is connected to the lever 38, and the rod 39 is provided inside 20 of the washing water tank 18. The rod 39 is made of metal as an example and is bent in an L shape. The first end portion of the chain 40 in the longitudinal direction is connected to the tip end portion of the rod 39. The second end in the longitudinal direction of the chain 40 is connected to the valve body 34.

The user can use the flush toilet 70 as follows. First, when the operating force on the lever 38 is released, the valve body 34 is pressed against the mount portion 33 by the water pressure inside the washing water tank 18 and is stopped. That is, the valve body 34 closes the drainage channel 37. Therefore, the washing water 30 is stored in the inside 20 of the washing water tank 18, and the height (water level) of the water surface 31 is at the initial position shown in FIG.

Further, when the float 29 floats on the water surface 31 of the washing water 30 and stops, and the water level of the washing water 30 is at the initial position, the passage 27 of the ball tap 24 is closed. Therefore, the washing water of the water supply channel 23 is not supplied to the inside 20 of the washing water tank 18. Further, the arm 28 is stopped at a position extended substantially horizontally.

On the other hand, when the user sits on the toilet seat 16 and excretes, the excrement falls into the puddle 14 of the toilet bowl 11. After that, when the user applies an operating force to the lever 38, the rod 39 operates within a predetermined angle range, and the chain 40 is pulled upward. Then, the valve body 34 is separated from the mount portion 33 against the water pressure, and the drainage channel 37 is opened. As a result, the washing water inside the washing water tank 18 flows into the puddle 14 through the washing water supply path 13 due to water pressure. Further, the excrement of the puddle 14 is discharged to the drainage channel 15 together with the washing water. When the washing water 30 passes between the valve body 34 and the mount portion 33, the valve body 34 receives a clockwise urging force about the support shaft 36 of the arm 35.

Further, when the washing water 30 is discharged to the washing water supply path 13, the water level of the washing water 30 in the inside 20 of the washing water tank 18 drops. Then, the float 29 descends by its own weight, and the arm 28 operates clockwise in FIG. Therefore, the passage 27 is opened, and the washing water supplied from the water supply pipe 22 is supplied (dropped) from the water supply channel 26 to the inside 20 of the washing water tank 18.

Further, when the user releases the operating force on the lever 38, the chain 40 is pulled downward by the weight of the valve body 34 and the water pressure received by the valve body 34, and the rod 39 operates in the opposite direction. Then, the arm 35 rotates counterclockwise, the valve body 34 is pressed against the mount portion 33, and the drainage channel 37 is closed. Therefore, the washing water 30 is stored in the inside 20 of the washing water tank 18, and the water level rises.

The float 29 rises as the water level of the washing water 30 rises, and the arm 28 operates counterclockwise. Then, when the water level of the washing water 30 rises to the initial position, the passage 27 is closed and the supply of the washing water 30 to the inside 20 of the washing water tank 18 is stopped.

The overflow pipe 44 is provided inside the washing water tank 18. The upper end of the overflow pipe 44 is located above the initial position of the water level of the washing water 30. The lower end of the overflow pipe 44 is connected to the drainage channel 37. Here, if a failure occurs in which the passage 27 is always open while the water level of the washing water 30 is in the initial position, the water level of the washing water 30 becomes higher than the initial position. Then, a part of the washing water 30 is discharged to the drainage channel 37 through the overflow pipe 44. Therefore, it is possible to prevent the water level of the washing water 30 from exceeding the upper limit position. The upper limit position is above the initial position and below the predetermined position.

The washing water supply device 10 of the present disclosure includes a detergent supply mechanism 45. The detergent supply mechanism 45 is provided to supply the detergent to the inside 20 of the washing water tank 18. The detergent supply mechanism 45 is provided over the inside 20 of the washing water tank 18 and the inside 46 of the lid 19. The inside 46 is a space, and when the lid 19 is placed on the washing water tank 18, the inside 20 and the inside 46 are connected. The interiors 20 and 46 are spaces surrounded by the washing water tank 18 and the lid 19.

The detergent supply mechanism 45 includes a container (tank) 47 for accommodating detergent, an on-off valve 48, a supply pipe 53, and a supply amount adjusting valve 49. The container 47 is provided inside 46 of the lid 19. The container 47 is made of, for example, a synthetic resin or a metal, and the detergent 51 is housed in the inside 50 of the container 47. An opening 52 is provided at the upper end of the container 47. The detergent 51 is, for example, a liquid detergent, and contains components such as sterilization, deodorization, fragrance, and antifungal in addition to a surfactant. The detergent 51 may be acidic, weakly acidic, neutral, weakly alkaline, or alkaline.

The supply pipe 53 is provided over the inside 46 and the inside 20. The supply pipe 53 is composed of parts other than the container 47 and the on-off valve 48, the upper end of the supply pipe 53 is connected to the container 47, and the lower end of the supply pipe 53 is connected to the on-off valve 48. The supply pipe 53 may be made of metal, synthetic resin, synthetic rubber, or the like. The supply pipe 53 may be fixed to the container 47, or may be attached to and detached from the container 47. The supply pipe 53 has a supply path 54, and the supply path 54 is connected to the inside 50 of the container 47.

The supply amount adjusting valve 49 is provided to adjust the flow rate of the detergent 51 supplied from the inside 50 of the container 47 to the inside 20 of the washing water tank 18. The supply amount adjusting valve 49 has an adjusting lever 74, and when the user manually operates the adjusting lever 74, the length at which the tip end portion of the adjusting lever 74 is located in the supply path 54 changes. Therefore, it is possible to adjust the area of the port through which the detergent 51 passes through the supply path 54. The area of the supply path 54 is an area in a plane perpendicular to the direction in which the detergent 51 passes through the supply path 54, that is, the direction along the center line A1. The adjusting lever 74 is provided inside 46.

The on-off valve 48 is provided inside 20 of the washing water tank 18. The on-off valve 48 is provided outside the region where parts such as the float 29, the chain 40, and the rod 39 operate. The on-off valve 48 has a housing 55 and a valve body 56. The housing 55 is a tubular member made of synthetic resin or metal, and a supply pipe 53 is connected to the housing 55. Further, the housing 55 is directly or indirectly supported by the washing water tank 18. For example, a support mechanism such as a support arm and a bracket is provided on the inner surface of the washing water tank 18, and the housing 55 is fixed by the support mechanism.

The housing 55 has a valve body accommodating chamber 57, and the valve body 56 is provided in the valve body accommodating chamber 57. The density of the material constituting the valve body 56 is smaller than the density of the washing water 30. The material of the valve body 56 is, for example, a synthetic resin and a ball shape. The valve body 56 can be operated in the valve body accommodating chamber 57 in the direction along the center line A1. The center line A1 is a virtual line representing the center of the housing 55, and the center line A1 is arranged in a substantially vertical direction, that is, in a direction along a vertical straight line.

Further, the housing 55 has an inward flange 58 forming the valve body accommodating chamber 57, and the discharge port 59 is provided by the inward flange 58. The inner peripheral surface of the inward flange 58 is a tapered surface that is inclined in a direction in which the inner diameter decreases as it approaches the discharge port 59. The discharge port 59 is connected to the inside 20 of the valve body accommodating chamber 57 and the washing water tank 18. The discharge port 59 is provided around the center line A1. The discharge port 59 is provided below the initial position of the water level of the washing water 30.

Further, the housing 55 surrounds the valve body accommodating chamber 57 and has an annular tapered surface 60 centered on the center line A1. The tapered surface 60 is inclined so that the inner diameter centered on the center line A1 expands as it approaches the discharge port 59. The housing 55 surrounds the valve body accommodating chamber 57 and has a straight surface 61 provided between the tapered surface 60 and the discharge port 59, and the inner diameter of the straight surface 61 is substantially constant. The diameter of the valve body 56 is larger than the minimum inner diameter of the tapered surface 60, smaller than the inner diameter of the straight surface 61, and larger than the inner diameter of the discharge port 59.

The action of the detergent supply mechanism 45 is as follows. When the water surface 31 of the washing water 30 is in the initial position, the water surface 31 of the washing water 30 is located above the discharge port 59. Therefore, a part of the washing water 30 has entered the valve body accommodating chamber 57. Therefore, the valve body 56 is floating on the washing water 30, and the valve body 56 is pressed against the tapered surface 60 to stop. When the valve body 56 is pressed against the tapered surface 60, the valve body 56 shuts off the supply path 54 and the discharge port 59. Therefore, the detergent 51 entering the supply path 54 by its own weight from the inside 50 of the container 47 is blocked by the valve body 56. That is, the detergent 51 is not mixed with the washing water 30.

Further, as shown in FIG. 2, the on-off valve 48 is located between the rod 39 and the chain 40 and the float 29 in a state where the arm 28 is stopped substantially horizontally and the float 29 is stopped. There is. The on-off valve 48 is not in contact with any of the rod 39, the chain 40 and the float 29.

Then, when an operating force is applied to the lever 38, the valve body 34 is separated from the mount portion 33, the washing water 30 is discharged to the drainage channel 37, and the water level of the washing water 30 drops, the valve body 56 becomes a valve body. It descends in the containment chamber 57. Then, the valve body 56 is separated from the tapered surface 60, and the supply path 54 is opened. That is, the supply path 54 and the discharge port 59 are connected. Therefore, the detergent 51 that has entered the housing 55 from the supply path 54 is mixed with the washing water 30, and the washing water 30 mixed with the detergent 51 is supplied from the discharge port 59 to the inside 20 of the washing water tank 18. .. Therefore, the cleaning water 30 mixed with the detergent 51 is supplied to the toilet bowl 11, and it is possible to prevent foreign matter, dirt, etc. from adhering to the inner surface of the toilet bowl 11, and the toilet bowl 11 can be kept hygienic.

Further, when the water surface 31 of the washing water 30 descends from the discharge port 59, the valve body 56 comes into contact with the tapered surface of the inward flange 58 and stops. When the valve body 56 comes into contact with the inward flange 58, the valve body 56 closes the discharge port 59. Therefore, the detergent 51 in the valve body accommodating chamber 57 is not mixed into the washing water 30. After that, when the water level of the washing water 30 in the inside 20 of the washing water tank 18 rises and becomes higher than the discharge port 59, the valve body 56 rises and is separated from the inward flange 58. Therefore, the detergent 51 in the valve body accommodating chamber 57 falls from the discharge port 59 by its own weight, and the detergent 51 is mixed into the cleaning water 30 inside the cleaning water tank 18. Further, when the valve body 56 is pressed against the tapered surface 60 and stopped, the supply path 54 is closed and the detergent 51 is not mixed with the washing water 30.

As described above, the opening / closing valve 48 of the present disclosure has a valve body 56 that floats on the washing water 30, and when the water level of the washing water 30 drops, the valve body 56 lowers, the supply path 54 is opened, and the inside 50 and the valve body 56 are opened. The inside 20 of the washing water tank 18 is connected, and the detergent 51 is mixed into the washing water 30. On the other hand, when the valve body 56 rises together with the water surface 31 of the washing water 30 and shuts off the inside 50 of the container 47 and the inside 20 of the washing water tank 18, the detergent 51 is not mixed in the washing water 30. Therefore, the user does not have to perform a dedicated operation to mix the detergent 51 into the cleaning water 30 inside the cleaning water tank 18. Therefore, it is possible to reduce the operational burden on the user.

Further, the container 47 is provided inside the lid 19 46, and the lid 19 does not need to be provided with a dedicated cover for covering the opening 52 of the container 47. Therefore, it is possible to suppress an increase in the number of parts and prevent foreign matter outside the lid 19 from entering the inside 50 of the container 47 through the opening 52. Further, when the lid 19 is removed from the washing water tank 18, the user can supply the detergent 51 to the inside 50 through the opening 52.

Further, the user can open the lid 19 and operate the supply amount adjusting lever 74 to adjust the area of the supply path 54. Specifically, when the area of the supply path 54 is expanded, the supply amount of the detergent 51 supplied to the washing water 30 increases. Therefore, the amount of the detergent 51 supplied to the washing water 30 of the container 47 can be arbitrarily changed according to the degree of dirt on the inner surface of the toilet bowl 11, the season, and the like. For example, since bacteria, viruses, and the like are more likely to propagate in the summer than in the winter, the supply amount of the detergent 51 in the summer can be made larger than the supply amount of the detergent 51 in the winter. Further, the on-off valve 48 is provided outside the operating region of the arm 28, the float 29, the chain 40, and the rod 39. Therefore, it is possible to prevent the arm 28, the float 29, the chain 40, and the rod 39 from coming into contact with the on-off valve 48.
