Detailed Description

Hereinafter, several embodiments of the washing water supply device will be described in detail with reference to the drawings. In the drawings for describing the embodiments, the same components are denoted by the same reference numerals in principle, and redundant description thereof will be omitted.

The flush water supply apparatus is used to flush toilets. The flush toilet 70 shown in fig. 1 includes a flush water supply device 10 and a toilet 11. The flush water supply device 10 is provided in a toilet bowl 11. The toilet bowl 11 is made of enamel (enamel) or synthetic resin, and is provided on the floor 12. The toilet 11 has a flush water supply path 13, a sump 14, and a drain path 15. The drain passage 15 is connected to a drain pipe not shown. The toilet 11 is provided with a seat 16 and a seat cover 17. Next, an embodiment of the flush water supply apparatus 10 will be explained in order.

< example 1 >

As shown in fig. 2, the flush water supply apparatus 10 includes a flush water tank 18 and a cover 19. The flush water tank 18 and the lid 19 are made of enamel or synthetic resin, and the flush water tank 18 has a tank shape. The flush tank 18 has a bottom 65 and a side wall 64. A bottom portion 65 is disposed along the upper surface of the floor 12, and a side wall 64 extends generally vertically upward from the bottom portion 65. The side wall 64 is disposed across the entire periphery of the bottom 65, and forms the space surrounded by the side wall 64, i.e., the interior 20. The inner portion 20 has an opening 21.

The lid 19 is placed on the upper end of the flush tank 18 in the height direction of the flush tank 18, and is disposed on the opening 21. The lid 19 separates the opening 21 from the exterior 71 of the flush tank 18. The lid 19 has a top plate 72 and a side wall 63 provided over the entire periphery of the top plate 72. The lower end of the side wall 63 rests on the upper end of the side wall 64. A projection 73 is provided inside the lower end of the side wall 63. Fig. 2 shows an example in which a plurality of projections 73 are provided at predetermined intervals along the entire circumference of the side wall 63. Further, the projection 73 may be provided annularly over the entire circumference of the side wall 63.

The projection 73 contacts the side wall 63, thereby preventing the cover 19 from moving in the horizontal direction with respect to the flush tank 18. Further, a projection may be provided at the upper end of the side wall 64. The height direction of the washing water 30 is the same as the vertical direction which is the direction of action of gravity. The water supply pipe 22 is provided outside the flush tank 18, and the water supply pipe 22 has a water supply path 23. The tap water is supplied to the water supply passage 23 at a predetermined water pressure. The water supply pipe 22 is provided in the flush tank 18 at a position close to the opening portion 21.

A float valve 24 is mounted on the water supply pipe 22. A float valve 24 is disposed in the interior 20 of the flush tank 18. The float valve 24 is a mechanism for supplying water supplied from the water supply pipe 22 to the interior 20 of the flush water tank 18 and stopping the supply. The float 24 includes a float body 25, a water supply passage 26 provided in the float body 25, a passage 27 connecting the water supply passage 26 and the water supply passage 23, an arm 28 attached to the float body 25 so as to be operable with a support shaft 41 as a fulcrum, 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 a hollow body made of, for example, synthetic resin, copper, stainless steel, or the like. The float 29 floats on the surface 31 of the flush water 30 stored in the interior 20 of the flush tank 18. The float 29 rises, falls, and stops in accordance with the amount of flush water 30 in the interior 20 of the flush tank 18, specifically the water level of the water surface 31. When the float 29 descends and ascends, the arm 28 operates, and the operating member 43 opens and closes the passage 27.

The flush pipe 32 is provided outside the flush tank 18, and the flush pipe 32 has a flush water supply passage 13. A fitting portion 33 is provided at the bottom portion 65, and a valve element (rubber float) 34 is provided in the interior 20 of the flush tank 18. The valve body 34 is made of synthetic rubber, and is connected to the arm 35. The arm lever 35 is supported by the mounting portion 33 so as to be movable about the support shaft 36. The valve body 34 is pressed in a direction toward the fitting portion 33 by the water pressure in the interior 20 of the flush water tank 18. The fitting portion 33 has a drain passage 37, and the drain passage 37 is connected to the flush water supply passage 13.

The lever 38 is mounted to a side wall 64 of the flush tank 18. The lever 38 is disposed at a horizontally opposite position of the side wall 64 from the water supply pipe 22. That is, the lever 38 is disposed at a horizontal interval from the water supply pipe 22. The lever 38 is provided at substantially the same position as the water supply pipe 22 in the height direction of the flush water tank 18, specifically, at a predetermined position. The technical meaning of the prescribed position is described later. The lever 38 is provided for a user to operate, and the valve body 34 is separated from the fitting portion 33 by an operating force.

The lever 38 is mounted to be rotatable within a predetermined angle with respect to the flush tank 18. The lever 38 is disposed on the outside 71 of the flush tank 18. A valve stem 39 is connected to the lever 38, the valve stem 39 being disposed in the interior 20 of the flush tank 18. For example, the valve rod 39 is made of metal and bent in an L-shape. The 1 st end of the chain 40 in the longitudinal direction is connected to the distal end of the valve rod 39. The 2 nd end of the chain 40 in the longitudinal direction is connected to the valve body 34.

The user can use the toilet 70 in the following manner. First, when the operating force to the lever 38 is in the released state, the valve body 34 is pressed against the fitting portion 33 by the water pressure in the interior 20 of the flush tank 18 and is in the stopped state. That is, the valve body 34 closes the drain passage 37. Thus, the flush water 30 is stored in the interior 20 of the flush tank 18 with the level of the water surface 31 (water level) at the initial position shown in FIG. 2.

Further, when the float 29 floats on the water surface 31 of the washing water 30 to stop and the water level of the washing water 30 is at the initial position, the passage 27 of the float valve 24 is closed. Therefore, the washing water of the water supply path 23 is not supplied to the interior 20 of the flush water tank 18. Further, the arm 28 is stopped at a position extending substantially horizontally.

On the other hand, when the user sits on the seat 16 and excretes, the excrement falls into the puddle 14 of the toilet bowl 11. Thereafter, when the user applies an operating force to the lever 38, the valve rod 39 operates within a predetermined angle range to pull the chain 40 upward. Then, the valve body 34 is separated from the fitting portion 33 against the water pressure, and the drain passage 37 is opened. As a result, the flush water in the interior 20 of the flush water tank 18 flows into the sump 14 through the flush water supply path 13 under water pressure. Further, the excrement in the puddle 14 is discharged to the drainage path 15 together with the flush water. When the flush water 30 passes between the valve body 34 and the mounting portion 33, the valve body 34 receives a clockwise biasing force about the support shaft 36 of the arm 35.

Further, when the flush water 30 is discharged to the flush water supply path 13, the level of the flush water 30 in the interior 20 of the flush water tank 18 is lowered. Then, the float 29 descends under its own weight, and the arm lever 28 operates clockwise in fig. 2. Thus, the passage 27 is opened, and the washing water supplied from the water supply pipe 22 is supplied (dropped) from the water supply path 26 to the interior 20 of the flush water tank 18.

When the user releases the operating force on the lever 38, the chain 40 is pulled downward by the weight of the valve element 34 and the water pressure applied to the valve element 34, and the valve rod 39 operates in the reverse direction. Then, the arm 35 rotates counterclockwise, the valve body 34 is pressed against the fitting portion 33, and the drain passage 37 is closed. Thus, the flush water 30 is retained within the interior 20 of the flush tank 18 and the water level rises.

The float 29 rises with the rise of the water level of the washing water 30, and the arm 28 works counterclockwise. Then, when the water level of the wash water 30 rises to the initial position, the passage 27 is closed, and the supply of the wash water 30 to the interior 20 of the wash water tank 18 is stopped.

An overflow pipe 44 is provided in the interior 20 of the flush tank 18. The upper end of the overflow pipe 44 is located above compared to the initial position of the water level of the wash water 30. The lower end of the overflow pipe 44 is connected to the drainage line 37. Here, if a failure occurs in which the passage 27 is normally open in a state in which the water level of the washing water 30 is at the initial position, the water level of the washing water 30 rises from the initial position. Then, a part of the flush water 30 is discharged to the drain passage 37 through the overflow pipe 44. Thus, the water level of the washing water 30 can be prevented 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 invention has a detergent supply mechanism 45. The detergent supply mechanism 45 is provided to supply detergent to the interior 20 of the flush tank 18. The detergent supply mechanism 45 is provided across the interior 20 of the flush tank 18 and the interior 46 of the lid 19. The interior 46 is a space, and the interior 20 is connected to the interior 46 when the cap 19 is placed on the flush tank 18. The

interiors

20 and 46 are spaces surrounded by the flush tank 18 and the lid 19.

The detergent supply mechanism 45 includes a container (tank) 47 for storing detergent, an opening/closing valve 48, a supply pipe 53, and a supply amount adjustment valve 49. A container 47 is disposed within the interior 46 of the lid 19. The container 47 is made of, for example, synthetic resin or metal, and a cleaning agent 51 is contained in an interior 50 of the container 47. An opening 52 is provided at the upper end of the container 47. The cleaning agent 51 is, for example, a liquid cleaning agent, and contains components such as a sterilizing component, a deodorizing component, a fragrance component, and a mold inhibitor in addition to a surfactant. The cleaning agent 51 may be any one of acidic, weakly acidic, neutral, weakly alkaline, and alkaline.

Supply tube 53 is disposed across interior 46 and interior 20. The supply pipe 53 is formed of a different component from the tank 47 and the opening/closing valve 48, and an upper end of the supply pipe 53 is connected to the tank 47 and a lower end of the supply pipe 53 is connected to the opening/closing valve 48. The supply pipe 53 may be made of any of metal, synthetic resin, synthetic rubber, and the like. The supply pipe 43 may be fixed to the container 47, or may be attachable to and detachable from the container 47. The supply pipe 53 has a supply passage 54, and the supply passage 54 is connected to the interior 50 of the container 47.

The supply amount adjustment valve 49 is provided to adjust the flow rate of the cleaning agent 51 supplied from the interior 50 of the container 47 to the interior 20 of the flush water tank 18. The supply amount adjusting valve 49 has an adjusting lever 74, and the user manually operates the adjusting lever 74 to change the length of the distal end portion of the adjusting lever 74 located in the supply passage 54. Therefore, the area of the orifice of the cleaning agent 51 passing through the supply path 54 can be adjusted. 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. An adjustment lever 74 is disposed within the interior 46.

An on-off valve 48 is provided in the interior 20 of the flush tank 18. The opening/closing valve 48 is provided outside the region where the float 29, the chain 40, the valve rod 39, and the like operate. The opening/closing valve 48 includes a housing 55 and a valve body 56. The housing 55 is a synthetic resin or metal tubular member, and the supply pipe 53 is connected to the housing 55. In addition, the housing 55 is supported directly or indirectly by the flush tank 18. For example, a support mechanism such as a support arm or a bracket is provided on the inner surface of the flush 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 disposed in the valve body accommodating chamber 57. The density of the material constituting the valve body 56 is lower than that of the flush water 30. The valve body 56 is made of, for example, a synthetic resin and has a spherical shape. The valve body 56 is operable in a direction along the center line A1 in the valve body accommodating chamber 57. The center line A1 is a virtual line indicating the center of the housing 55, and the center line A1 is arranged substantially in the vertical direction, that is, in the direction along the vertical line.

The housing 55 has an inward flange 58 forming the valve body accommodating chamber 57, and a discharge port 59 is provided in the inward flange 58. The inner peripheral surface of the inward flange 58 is a tapered surface inclined in the following direction: the inner diameter decreases as the discharge port 59 is approached. The drain port 59 is connected to the valve element accommodating chamber 57 and the interior 20 of the flush water tank 18. The discharge port 59 is provided with the center line A1 as the center. The discharge port 59 is disposed below compared to the initial position of the water level of the washing water 30.

Further, the housing 55 has an annular tapered surface 60 surrounding the valve body accommodating chamber 57 and centered on the center line A1. In the tapered surface 60, the inner diameter centered on the center line A1 is inclined in a direction expanding toward the discharge port 59. The housing 55 has a flat surface 61 surrounding the valve element accommodating chamber 57 and provided between the tapered surface 60 and the discharge port 59, and the inner diameter of the flat surface 61 is substantially constant. The valve element 56 has a diameter larger than the minimum inner diameter of the tapered surface 60, smaller than the inner diameter of the flat surface 61, and larger than the inner diameter of the discharge port 59.

The detergent supply mechanism 45 functions as follows. When the water surface 31 of the washing water 30 is at 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 enters the valve body housing chamber 57. Therefore, the valve body 56 floats on the flush water 30, and the valve body 56 is pressed against the tapered surface 60 and stops. When the valve body 56 is pressed against the tapered surface 60, the valve body 56 blocks the supply passage 54 and the discharge port 59. Therefore, the cleaning agent 51 entering the supply path 54 from the inside 50 of the container 47 by its own weight is blocked by the valve body 56. That is, the detergent 51 is not mixed into the washing water 30.

Further, as shown in fig. 2, in a state where the arm 28 is stopped substantially horizontally and the float 29 is stopped, the on-off valve 48 is positioned between the stem 39, the chain 40, and the float 29. The open/close valve 48 is not in contact with the valve rod 39, the chain 40, and the float 29.

Then, when an operating force is applied to the lever 38 to separate the valve body 34 from the mounting portion 33 and the flush water 30 is discharged from the drain passage 37 to lower the level of the flush water 30, the valve body 56 is lowered in the valve body housing chamber 57. Then, the valve body 56 moves away from the tapered surface 60, and the supply passage 54 is opened. That is, the supply passage 54 and the discharge port 59 are connected. Therefore, the detergent 51 entering the housing 55 from the supply passage 54 is mixed into the flush water 30, and the flush water 30 mixed with the detergent 51 is supplied from the discharge port 59 to the interior 20 of the flush water tank 18. Therefore, the flush water 30 mixed with the cleaning agent 51 is supplied to the toilet bowl 11, and it is possible to prevent foreign matter, dirt, and the like from adhering to the inner surface of the toilet bowl 11, and to keep the toilet bowl 11 sanitary.

When the water surface 31 of the washing water 30 drops below the discharge port 59, the valve body 56 contacts the tapered surface of the inward flange 58 and stops. When the spool 56 contacts the inward flange 58, the spool 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. Thereafter, when the level of the flush water 30 in the interior 20 of the flush tank 18 rises above the discharge port 59, the valve body 56 rises and moves away from the inward flange 58. Therefore, the detergent 51 in the valve body housing chamber 57 falls down from the discharge port 59 by its own weight and is mixed into the flush water 30 in the interior 20 of the flush water tank 18. When the valve body 56 is pressed against the tapered surface 60 and stopped, the supply passage 54 is closed, and the detergent 51 is not mixed into the washing water 30.

As described above, the on-off valve 48 of the present invention has the valve body 56 floating on the flush water 30, and when the level of the flush water 30 decreases, the valve body 56 moves downward, the supply passage 54 is opened, the interior 50 and the interior 20 of the flush water tank 18 are connected, and the detergent 51 is mixed into the flush water 30. In contrast, when the valve body 56 rises together with the water surface 31 of the flush water 30 to cut off the interior 50 of the tank 47 from the interior 20 of the flush water tank 18, the cleaning agent 51 is not mixed into the flush water 30. Thus, the user can mix the cleaning agent 51 into the flush water 30 in the interior 20 of the flush tank 18 without performing a dedicated operation. Thus, the operation load of the user can be reduced.

The container 47 is provided in the interior 46 of the lid 19, and the lid 19 can be satisfied without providing a dedicated lid for covering the opening 52 of the container 47. Therefore, the number of parts can be suppressed from increasing, and foreign matter outside the lid 19 can be prevented from entering the interior 50 of the container 47 through the opening 52. Further, when the lid 19 is detached from the flush water tank 18, the user can supply the detergent 51 into the interior 50 through the opening 52.

Further, the user can open the lid 19 to operate the adjustment lever 74 to adjust the area of the supply passage 54. Specifically, when the area of the supply passage 54 is increased, the supply amount of the detergent 51 supplied to the washing water 30 is increased. Therefore, the supply amount of the cleaning agent 51 from the tank 47 to the flush water 30 can be arbitrarily changed according to the degree of contamination of the inner surface of the toilet bowl 11, the season, and the like. For example, since bacteria, viruses, and the like are easily propagated in summer as compared with winter, the amount of detergent 51 to be supplied in summer can be made larger than the amount of detergent 51 to be supplied in winter. Further, the on-off valve 48 is provided outside the working area of the arm 28, the float 29, the chain 40, and the valve rod 39. Therefore, the arm 28, the float 29, the chain 40, and the valve rod 39 are prevented from contacting the opening/closing valve 48.

< example 2 >

Fig. 4 shows an embodiment 2 of the washing water supply apparatus 10, wherein the tank 47 is provided on the outside 71. A portion of the supply pipe 53 extends in a substantially horizontal direction. The reservoir 47 is disposed above the lever 38 and on the side of the lid 19 in the height direction of the flush tank 18. The receptacle 47 is disposed outside the working area of the shift lever 38. Further, a lid 62 is provided to cover the opening 52 of the container 47. The supply pipe 53 is bent in an L-shape, and a part of the supply pipe 53 is arranged above the valve rod 39. The supply pipe 53 is arranged outside the working area of the valve stem 39.

The supply pipe 53 may be arranged to the outside of the cover 19 via a through hole provided on the side wall 63 of the cover 19. When a part of the supply pipe 53 is provided in the through hole provided in the side wall 63 of the lid 19, the container 47, the housing 55, and the supply pipe 53 are supported by the lid 19. In the example shown in fig. 4, a part of the supply pipe 53 is disposed outside the lid 19 through a through hole (not shown) provided in the side wall 64 of the flush water tank 18. The container 47, the housing 55, and the supply pipe 53 are supported by the lid 19. The center line A1 is an imaginary line indicating the center of the housing 55.

Further, the container 47 is provided on the outside 71 and the housing 55 is provided on the inside 20, and the container 47 and the housing 55 are provided at different positions in a substantially horizontal direction. Therefore, the supply pipe 53 is assembled by connecting pipes, elbows, and the like as necessary. The other configuration of the flush water supply apparatus 10 shown in fig. 4 is the same as that of the flush water supply apparatus 10 shown in fig. 2.

The same effects as those of embodiment 1 of the washing water supply apparatus 10 can be obtained in embodiment 2 of the washing water supply apparatus 10. Further, the user can supply the detergent 51 to the inside 50 by removing the cover 62 from the container 47, without removing the cover 19 from the flush tank 18. Further, if the container 47 is transparent or translucent, the user can visually confirm the amount of the detergent 51 in the interior 50 of the container 47.

In fig. 4, the supply pipe 53 may be disposed outside 71 of the cover 19 through a notch provided in the side wall 63 of the cover 19. Further, if the side wall 64 of the flush tank 18 extends upward as compared with fig. 4, the supply pipe 53 may be disposed to the outside 71 through a through hole or a notch portion provided in the side wall 64. In this case, the tank 47, the housing 55, and the supply pipe 53 are supported by the flush tank 18. Further, in fig. 4, the supply amount adjusting valve 49 may be provided on the outside 71 as indicated by the two-dot chain line. With this configuration, the user can operate the adjustment lever 74 without detaching the lid 19 from the flush tank 18. Thus, the operation burden on the user is reduced.

< example 3 >

Fig. 5 shows an embodiment 2 of the washing water supply device 10, in which the lid 19 has a bowl 75, and a side wall 63 is connected to the bowl 75 over the entire periphery thereof. The bowl portion 75 is made of enamel and is integral with the side wall 73. The bowl 75 is a component for guiding the flush water before being supplied to the flush water tank 18. Bowl 75 has drain port 76. A hand washing tube 77 is mounted on the bowl 75. The hand washing tube 77 is made of metal or synthetic resin. The hand washing pipe 77 extends upward from the bowl 75 and is bent in a J-shape. The discharge port of the hand washing pipe 77 is disposed outside 71.

A connection pipe 78 is provided for connecting the open end of the hand washing pipe 77 on the bowl 75 side to the water supply path 26. The connection pipe 78 is a rubber hose or a bellows, and has flexibility. The connection pipe 78 is provided in the space B1 surrounded by the side wall 63 and the bowl portion 75. The connection pipe 78 is set in its length in the following manner: when the lid 19 is removed from the flush tank 19 and the opening 21 is opened, the connection pipe 78 can be maintained in a state of being connected to the hand washing pipe 77 and the water supply path 26. Further, a part of the supply pipe 53 in the longitudinal direction is disposed in the space B1.

In the washing water supply device 10 shown in fig. 5, when the lever 38 is operated, the water level of the washing water 30 is lowered, and the passage 27 is opened, the washing water supplied to the water supply passage 26 flows into the hand washing pipe 77 through the connection pipe 78 under water pressure, and the washing water is discharged from the discharge port of the hand washing pipe 77. The washing water is jetted downward, specifically, toward the bowl 75. When the user inserts his or her hand between the bowl 75 and the spouting portion of the hand washing pipe 77, the hand is washed with the washing water. The washing water discharged from the discharge portion of the hand washing pipe 77 flows along the surface of the bowl 75 and falls down from the drain port 76 into the interior 20.

The other configuration of the flush water supply apparatus 10 shown in fig. 5 is the same as the configuration of the flush water supply apparatus 10 shown in fig. 2 and 4. The effect of the flush water supply apparatus 10 shown in fig. 5 is the same as that of the flush water supply apparatus 10 shown in fig. 2 and 4. In fig. 5, the container 47 may be provided in the space B1. In this case, the height of the side wall 63 and the height of the bowl 75 are determined so that the container 47 does not contact the bowl 75.
