In this case, the valve 4 (4a and / or 4b) can be opened when the string 6 is in tension and the valve 4 can be closed when the string 6 is relaxed. Conversion between the tension state and the relaxed state of the string-like body 6 is performed by the rotation of the rotating body 5. Further, although not shown, these connections may be made using a rod-like body or a gear.

Next, the configurations and operations of the rim connection portion 51 and the rim / jet connection portion 52, and the first rim string-like body 61a, the second rim string-like body 62a, and the jet string-like body 62b will be described with reference to FIGS.

FIG. 7 is a schematic perspective view illustrating another configuration of the toilet apparatus according to this embodiment.
FIG. 8 is a schematic cross-sectional view illustrating the operation of the toilet apparatus having the configuration illustrated in FIG.
FIG. 9 is a schematic view illustrating still another configuration of the toilet apparatus according to this embodiment.

  As shown in FIG. 4, the rim connection portion 51 and the rim / jet connection portion 52 have an angle formed by the rim connection portion 51, the rotation shaft 5 s, and the rim / jet connection portion 52 at a rotation surface of about 180. It may be configured to be degrees. This is the same configuration as that shown in FIG.

  In this case, as shown in FIG. 5A, when the connecting portions 51 and 52 are located in the range R1 and the range R2 in the Z-axis direction (substantially vertical direction), for example, both are substantially the same. The string-like body 6 can be provided so that the string-like bodies 61a and 62a and 62b are in a relaxed state (when in position).

  Further, as shown in FIG. 5B, when the rim / jet connecting portion 52 moves to the positive side of the Z axis and deviates from the range R2, the second rim string-like body 62a and the jet string-like body 62b are respectively rimmed. The second rim string-like body 62a and the jet string-like body 62b can be provided so as to be tensioned to such an extent that the control valve 4a and the jet control valve 4b can be opened.

  Further, as shown in FIG. 5C, when the rim connecting portion 51 moves to the positive side of the Z axis and deviates from the range R1, the first rim string-like body 61a is tensioned enough to open the rim control valve 4a. As described above, the first rim string-like body 61a can be provided.

  The ranges R1 and R2 may be the same value or different values. These values are the state in which the string-like bodies 61a, 62a, and 62b are relaxed (first state), the state in which the string-like bodies 62a and 62b are in tension (second state), and the string-like body 61a in tension. It can be set to any value as long as all the states (third state) in which the state body 62b relaxes can be expressed.

With this configuration, when the rotator 5 rotates in the first direction (for example, counterclockwise direction) when the rim control valve 4a and the jet control valve 4b are closed, the rim control valve 4a and the jet control valve When 4b is opened and the rim control valve 4a and the jet control valve 4b are closed, the rim control valve 4a alone can be opened by rotating in the second direction (for example, clockwise direction).
By utilizing this operation, the valves 4a and 4b can be controlled in various ways.

As illustrated in FIG. 1, the toilet apparatus 1 according to the present embodiment can further include a drive unit D that drives the rotating body 5 and a control unit C that controls the drive unit D. The controller C includes a first state in which both the rim control valve 4a and the jet control valve 4b are closed, a second state in which both the rim control valve 4a and the jet control valve 4b are opened, The drive unit D can be instructed to reversibly and directly or indirectly switch between the third state in which the control valve 4a is opened and the jet control valve 4b is closed.
The drive part D may be a motor, for example. Further, the control unit C may be provided in the drive unit D.

In the first state, no water is supplied to the toilet. For this reason, the first state may be manifested when not in use.
In the second state, a rim flow and a jet flow are supplied. For this reason, the second state may be manifested when washing the toilet bowl. The time for which the second state lasts may be selected from two or more times, for example, three times. Thereby, the amount of water supplied to the toilet can be set in multiple stages (for example, large, small, large, medium, and small (the ratio is, for example, 6: 5: 4)).
In the third state, only the rim flow is supplied. For this reason, the 3rd state may be expressed when forming the sealing water of a toilet bowl, or wash | cleaning the bowl part of a toilet bowl. The time for which the third state lasts may be sufficient time to form a toilet seal or enough time to clean the toilet bowl.

In the operation illustrated in FIG. 5, the control unit C instructs the driving unit D to rotate the rotating body 5 so that the connection units 51 and 52 are, for example, substantially the same position in the Z-axis direction. 1 is realized (FIG. 5A).
Further, when the control unit C instructs the drive unit D to rotate the rotating body 5 counterclockwise, the second state can be realized (FIG. 5B).
Further, when the control unit C instructs the drive unit D to rotate the rotating body 5 clockwise, the third state can be realized (FIG. 5C).

  By these operations, for example, the control shown in FIG. 6 can be performed. That is, the control unit C can instruct the drive unit D to develop the second state, the first state, and the third state in this order.

  As shown in FIG. 6, in the time zone (1), the rim control valve 4a and the jet control valve 4b are closed to be in the first state. Thereafter, in the time zone (2), which is the time of cleaning, the rotator 5 rotates counterclockwise, and the rim control valve 4a and the jet control valve 4b are opened to enter the second state. Thereafter, in the time zone (3), the rotating body 5 rotates in the reverse direction (rotates clockwise), the rim control valve 4a and the jet control valve 4b are closed, and the first state is entered. Thereafter, in the time zone (4) during refilling, the rotator 5 further rotates clockwise, and only the rim control valve 4a is opened to enter the third state. In addition, "refill" is supplying water for forming toilet seal water to the toilet. Thereafter, in the time zone (5), the rotator 5 rotates in the reverse direction (rotates counterclockwise) and enters the first state. That is, the control unit C operates the driving unit D to form the second state and generates a siphon in the toilet, and then operates the driving unit D to form the third state and fills the toilet with sealing water. Can be made.

  As shown in FIG. 7, in the present embodiment, the valves 4a and 4b may be valves that move in the vertical direction. Thereby, since the moving direction of the connection parts 51 and 52 and the moving direction of a valve become substantially the same, the reliability improvement of the opening / closing operation | movement of a valve is achieved.

  The operation in this case is as shown in FIG. The valves 4a and 4b are opened and closed by a mechanism similar to the mechanism described above with reference to FIG. 5, and the first state (FIG. 8A), the second state (FIG. 8B), and the third state. (FIG. 8 (c)) is expressed.

  Further, the rotating shaft 5s may be on the rotating surface (XZ plane) of the valves 4a and 4b having hinges as shown in the above, or with respect to the XZ plane as shown in FIG. 9A. It may be substantially vertical. Also in this case, the same operation and control as described above can be performed as shown in FIG.

  As shown in FIG. 1, the toilet apparatus 1 according to the present embodiment includes an information acquisition unit A that acquires information (hereinafter referred to as “water supply information”) that determines the necessity of water supply and the water supply mode. Furthermore, you may prepare. In this case, the control unit C can use the information acquired by the information acquisition unit A in at least part of the case where an instruction is given to the drive unit D.

  The information acquisition unit A may include a detection unit S that detects the first original information that is the basis of the water supply information. The first original information may be, for example, a user sitting time.

  Moreover, the information acquisition means A may have the input means E for a user to input the 2nd original information used as the basis of water supply information. The input means E may be attached to a toilet bowl or a wall, or may have the form of a remote control. The user can select the mode of water supply to the toilet by pressing a button on the input means E.

  When both the detection means S and the input means E are provided, the information acquisition means A can acquire the water supply information using the first and second original information. In this case, when a wrinkle occurs between the first original information and the second original information, the second original information may be prioritized. For example, according to the first original information (detection information), it is determined that the amount of water supplied to the toilet bowl should be increased, whereas according to the second original information (input information), water to be supplied to the toilet bowl is to be determined. If it is determined that the amount may be small, the water supply information may be acquired based on the second original information. Thereby, the control part C can perform an appropriate instruction | indication with respect to the drive part D based on this water supply information. As a result, water is supplied with an appropriate amount of water.

  The information acquisition unit A, the detection unit S, and / or the input unit E may be configured to remotely operate the control unit C.

(Effect of this embodiment)
Next, the effect of this embodiment will be described with reference to FIG.
FIG. 10 is a schematic cross-sectional view showing a toilet apparatus according to a comparative example compared with this embodiment. This toilet apparatus 200 is used for a siphon jet flush toilet.

  As illustrated in FIG. 10, the toilet apparatus 200 according to the comparative example includes two water supply paths branched by ball taps (a tank water supply path 201 and a refill water supply path 202). Water supplied to the tank flows through the tank water supply channel 201. On the other hand, water used for toilet refill flows through the refill water supply channel 202. That is, the refill water is directly supplied from a water pipe or the like without going through the tank.

  In such a configuration, when the toilet is washed by flowing wash water from the tank to the toilet, water is supplied into the tank by the function of a ball tap float (not shown) and an overflow pipe. Hereinafter, a case where the tank water supply takes 60 seconds when the amount of cleaning water is small, and 75 seconds when the amount is large, will be described as an example.

  Here, in general, the flow rate related to refilling is set so that a sufficient amount of sealed water is formed when the time required for tank water supply when the amount of washing water is small has elapsed. This setting is performed by adjusting the flow path resistance. By setting in this way, even when the amount of washing water is small or large, in other words, when the tank water supply time is short or long, the sealed water is sufficiently formed. For this reason, in this example, it is assumed that the tank is sufficiently refilled when the tank water is supplied for 60 seconds.

  The amount of water required for refilling is usually constant regardless of the amount of cleaning water. This is because almost all of the water in the bowl is discharged by the siphon phenomenon regardless of the amount of washing water, and the amount of water on the bowl surface after washing becomes equal.

  As shown in FIG. 10A, when the amount of washing water is small, the tank water supply requires 60 seconds, and therefore water flows through the tank water supply channel 201 for 60 seconds. At this time, water also flows through the refill water supply path 202 for 60 seconds. Thereby, the sealing water of a toilet bowl is formed appropriately.

On the other hand, as shown in FIG. 10B, when the cleaning water is large, the tank water supply takes 75 seconds, so that the water flows in the tank water supply channel 201 for 75 seconds. At this time, water also flows in the refill water supply path 202 at the same time for 75 seconds. Also in this case, the toilet seal water is fully formed. However, since the sealed water has already been properly formed when the water is supplied for 60 seconds, the water that has flowed during the remaining 15 seconds has been supplied wastefully.
Thus, in the comparative example, if there is a difference in the amount of drainage from the tank, wastewater is generated, and if the difference in the amount of drainage becomes large, the wastewater increases.

On the other hand, the toilet device 1 according to the present embodiment independently controls the amount of water necessary for forming the sealed water (in other words, the time during which the third state is continued) by the control unit C or the like. It does not depend on the amount of washing water or the tank level. Thereby, the problem which concerns on the waste water mentioned above is eliminated, and improvement of water saving is achieved. Moreover, the structure is simplified by using two valves (valves 4a and 4b). For this reason, cost reduction and device reliability improvement are achieved.
Thus, according to this embodiment, the toilet apparatus which is excellent in water saving and has a simple structure is provided.

(Other configuration and control of this embodiment)
Next, another control of the toilet apparatus 1 according to the present embodiment will be described with reference to FIGS. 11 and 12.
11 and 12 are schematic views illustrating other control modes of the valves 4a and 4b when the connecting portions 51 and 52 and the string-like bodies 61a, 62a, and 62b are configured as illustrated in FIG. is there.

  As illustrated in FIG. 11, the control unit C can instruct the driving unit D to develop the second state and the first state in this order. In this case, the third state is not manifested and no sealed water is formed in the toilet bowl. That is, the control unit C operates the driving unit D to form the second state and generates a siphon in the toilet, and then operates the driving unit D to form the first state and fills the toilet with sealing water. You can avoid it. Accordingly, such a control mode can be suitably used when cleaning or checking the toilet bowl (cleaning mode).

  Such an operation is realized by the control unit C instructing the drive unit D by deleting the instructions related to the time zones (4) and (5) in the instruction described above with reference to FIG.

  Also, as shown in FIG. 12, the control unit C instructs the drive unit D to further develop the third state before the second state in the control described above with reference to FIGS. It can be performed. That is, the control unit C operates the driving unit D to form the third state and supply water to the bowl surface of the toilet bowl, and then operates the driving unit D to form the second state and cleans the toilet bowl. Can be made. Thereby, “pre-cleaning” is performed. That is, before using the toilet bowl, a water film can be formed on the surface of the toilet bowl to suppress the adhesion of dirt. In this case, it can be configured that the pre-cleaning is automatically performed by detecting that the user is seated using the detection means S.

  Such an operation is realized by the control unit C instructing the drive unit D to rotate the rotating body 5 clockwise before the time zone (1) in the instructions of FIG. 6 and FIG. Is done.

Next, another configuration and control of the toilet apparatus 1 according to the present embodiment will be described with reference to FIGS. 13 and 14.
FIG. 13 is a schematic view illustrating another configuration of the connecting portions 51 and 52 and the string-like bodies 61a, 62a, and 62b. This figure represents the rotation surface of rotation of the rotating body 5 when the negative side is viewed from the X axis positive side in FIG.

  FIG. 14 is a schematic view illustrating the control mode of the valves 4a and 4b when the connecting portions 51 and 52 and the string-like bodies 61a, 62a, and 62b are configured as illustrated in FIG.

  As shown in FIG. 13, the rim connection portion 51 and the rim / jet connection portion 52 have an angle formed by the rim connection portion 51, the rotation shaft 5 s, and the rim / jet connection portion 52 on the rotation surface. It may be configured to be degrees. For example, the connecting portion 51 can be disposed in the Z-axis negative side direction with the rotation shaft 5s as the origin, and the connecting portion 52 can be disposed in the Y-axis positive side direction.

  In this case, as shown in FIGS. 13A to 13C, when the connecting portion 51 and the connecting portion 52 are located in the ranges R1 and R2, respectively, in the Z-axis direction, the string-like bodies 61a, 62a and 62b are in a relaxed state, and when they deviate from these ranges, they can be in a tensioned state.

  As a result, the rotating body 5 opens the rim control valve 4a and the jet control valve 4b when rotating in the first direction (for example, counterclockwise direction) in a state where the rim control valve 4a and the jet control valve 4b are closed. When rotating in the first direction, only the jet control valve 4b can be closed.

  That is, as shown in FIG. 13A, when the connecting portion 51 is in the vicinity of the lower end of the rotating track, for example, the string-like bodies 61a and 62a and 62b are in a relaxed state, and the valves 4a and 4b are closed. It becomes a state. As a result, the first state is realized.

  Further, as shown in FIG. 13B, when the connecting portion 52 is near the upper end of the rotating track, for example, the string-like bodies 62a and 62b are in a tensioned state, and the valves 4a and 4b are in an opened state. . As a result, the second state is realized.

  Further, as shown in FIG. 13C, when the connecting portion 51 is in the vicinity of the upper end of the rotating track, for example, only the string-like body 61a is in a tensioned state and only the valve 4a is opened. As a result, the third state is realized.

  By performing such an operation, the control shown in FIG. 14 can be performed. That is, the control unit C can instruct the driving unit D to develop the second state, the third state, and the first state in this order.

  As shown in FIG. 14, in the time zone (1), the state shown in FIG. Thereafter, in the time zone (2), which is the time of cleaning, the rotator 5 rotates counterclockwise and enters the state shown in FIG. Thereafter, in the time zone (3) during refilling, the rotator 5 further rotates counterclockwise to the state shown in FIG. Thereafter, in the time zone (4), the rotating body 5 further rotates counterclockwise and returns to the first state.

  Next, still another configuration and control of the toilet apparatus 1 according to the present embodiment will be described with reference to FIGS. 15 and 16.

  In this embodiment, the connection parts 51 and 52 are arbitrary as long as it can switch reversibly between the 1st state, the 2nd state, and the 3rd state directly or indirectly. It can be provided in the position. Further, when the string-like body 6 is used, the string-like bodies 61a, 62a, 62b and the ranges R1, R2 are directly between the first state, the second state, and the third state. As long as it can be switched reversibly or indirectly, it can be provided and set in any position / mode. That is, when both the first rim string-like body 61a and the second rim string-like body 62a and the jet string-like body 62b are in the relaxed state (first state), the second rim string-like body The first rim when the state body 62a is in a tensioned state that can open the rim control valve 4a and the jet string-like body 62b is in a state of tension that can open the jet control valve 4b (second state). As long as the string-like body 61a is tensioned enough to open the rim control valve 4a and the jet string-like body 62b is in a relaxed state (third state), it is provided in any position / mode. Can be set.

Hereinafter, the case where the string-like body 6 is used will be described as an example.
15 and 16 are schematic views illustrating still another configuration of the connection portions 51 and 52 and the string-like bodies 61a, 62a, and 62b. These drawings, like FIG. 4, represent the rotation plane of rotation of the rotating body 5 when the negative side is viewed from the X axis positive side in FIG. 1.

  The connecting portions 51 and 52 may be provided at the same position on the rotation surface, or may be provided at different positions as described above. Further, the turning radii of the connecting portions 51 and 52 may be the same or different.

  As shown in FIG. 15A, the rim connecting portion 51 and the rim / jet connecting portion 52 may be provided at substantially the same position on the rotation surface. In this case, the first rim string-like body 61a, the second rim string-like body 62a, and the jet string-like body 62b are made to have different lengths (the first rim string-like body 61a is relatively shortened). ) Or the like, the timing at which each of the rotating bodies 5 is in a tension state can be varied. In other words, the upper end of the range R1 is set to be lower than the upper end of the range R2. Thereby, the three states described above can be realized.

  That is, first, when all of the first rim string-like body 61a and the second rim string-like body 62a and the jet string-like body 62b are in the relaxed state, the first rim string-like body 61a as shown in FIG. This state is realized. Thereafter, when the rotating body 5 rotates counterclockwise, as shown in FIG. 15B, the connecting portions 51 and 52 move to the Z axis positive side. In this case, since the first rim string 61a is relatively short, the first rim string 61a is initially in a tension state. Thereby, the third state can be realized. Thereafter, when the rotating body 5 further rotates counterclockwise and the connecting portions 51 and 52 further move to the positive side of the Z axis, the second rim string body 62a and the jet string body 62b are also in tension. Thereby, the second state can be realized. Thereafter, when the rotating body 5 further rotates counterclockwise, or when the rotating body 5 rotates in the reverse direction, the connecting portions 51 and 52 move to the Z-axis negative side, and the third state and the first state are in this order. Can be realized.

  Further, as shown in FIG. 16A, the rim connecting portion 51 and the rim / jet connecting portion 52 are positioned on a line extending in the substantially same direction from the rotating shaft 5s and at different positions of the rotation radius. More specifically, the rim connecting portion 51 may be provided so that the radius of rotation is relatively large. Also in this case, as described above with reference to FIG. 15, the first rim string-like body 61a, the second rim string-like body 62a, and the jet string-like body 62b are different from each other in the three states described above. Can be realized. Even if the lengths of these string-like bodies 6 are substantially the same, the rotation radii of the connecting portions 51 and 52 are different, so that the first rim string-like body 61a and the second The timing at which the rim string-like body 62a and the jet string-like body 62b are in a tension state can be made different. That is, when the rotating body 5 rotates counterclockwise, as shown in FIG. 16B, the rim connecting portion 51 moves by a relatively large distance despite the same rotation angle (distance L1>). Distance L2). As a result, the first rim string-like body 61a is in a tension state first. Thereafter, when the rotating body 5 further rotates counterclockwise and the connecting portions 51 and 52 further move to the positive side of the Z axis, the second rim string body 62a and the jet string body 62b are also in tension. In this way, the first state, the third state, and the second state can be realized in this order. These states can then be realized in reverse order by further rotation or reverse rotation.

  In the above description, the same operation can be realized by providing the connecting portions 51 and 52 at symmetrical positions with respect to the rotation shaft 5s and reversing the rotation.

In this case, the user can manually supply cleaning water and sealing water using the tool T. The amount of water can be adjusted by changing the time that the tool T operates.

  The tool T can be used in combination with the information acquisition unit A, the control unit C, and the driving unit D described above. In this case, the cleaning water or the like can be normally supplied using the control unit C or the like, and the cleaning water or the like can be manually supplied using the tool T at the time of a power failure.
