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 5a and the jet connection portion 5b, and the rim string-like body 6a and the jet string-like body 6b will be described with reference to FIG. 1 and FIGS.

FIG. 9 illustrates the operation of the rotating body 5, the string-like bodies 6a and 6b, and the valves 4a and 4b when the connecting portions 5a and 5b and the string-like bodies 6a and 6b are configured as shown in FIG. FIG.
FIG. 10 is a schematic view illustrating the control mode of the valves 4a and 4b when the connecting portions 5a and 5b and the string-like bodies 6a and 6b are configured as shown in FIG.
FIG. 11 is a schematic view illustrating another configuration of the toilet apparatus 1 when the connecting portions 5a and 5b and the string-like bodies 6a and 6b are configured as illustrated in FIG.

  As shown in FIG. 8, the rim connection portion 5a and the jet connection portion 5b have an angle formed by the rim connection portion 5a, the rotation shaft 5s, and the jet connection portion 5b on the rotation surface is approximately 180 degrees. May be configured. This is the same configuration as that shown in FIGS.

  In this case, as shown in FIG. 9A, when the connecting portions 5a and 5b are located in the range Ra and the range Rb in the Z-axis direction (substantially vertical direction), respectively (for example, both are in substantially the same position). The string-like bodies 6a and 6b can be provided so that the string-like bodies 6a and 6b are in a relaxed state respectively.

  Further, as shown in FIG. 9B, when the jet connecting portion 5b moves to the positive side of the Z axis and deviates from the range Rb, the jet string-like body 6b is moved to the jet control valve 4b (and the rim control valve by the pushing operation). The jet string-like body 6b can be provided so as to be tense enough to open 4a).

  Further, as shown in FIG. 9C, when the rim connecting portion 5a moves to the positive side of the Z axis and deviates from the range Ra, the rim string-like body 6a is so tensioned that it can open the rim control valve 4a. The rim string-like body 6a can be provided.

  The ranges Ra and Rb may be the same value or different values. These values are a state in which the string-like bodies 6a and 6b are relaxed (first state), a state in which at least the string-like body 6b is in tension (second state), and a state in which only the string-like body 6a is in tension (third state). As long as all the states of (1) can be expressed, it can be set to an arbitrary value.

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. 9, the control unit C instructs the driving unit D to rotate the rotating body 5 so that the connection units 5 a and 5 b are in, for example, substantially the same position in the Z-axis direction. 1 is realized (FIG. 9A).
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. 9B).
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. 9C).

  By these operations, for example, the control shown in FIG. 10 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. 10, 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 opens the rim control valve 4a and the jet control valve 4b to generate siphon in the toilet, and then opens the rim control valve 4a while closing the jet control valve 4b. The toilet can be filled with sealed water.

  The rotating shaft 5s may be on the rotating surface (XZ plane) of the hinged valves 4a and 4b as shown in the drawings, or with respect to the XZ plane as shown in FIG. 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. 12 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. 12, the toilet apparatus 200 according to the comparative example has two water supply paths branched by a ball tap (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. 12A, when the amount of washing water is small, the tank water supply requires 60 seconds, so that 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. 12B, when the amount of washing water is large, the tank water supply takes 75 seconds, so 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. 13 and 14.
13 and 14 are schematic views illustrating other control modes of the valves 4a and 4b when the connecting portions 5a and 5b and the string-like bodies 6a and 6b are configured as illustrated in FIG.

  As illustrated in FIG. 13, the control unit C can instruct the drive 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 opens the rim control valve 4a and the jet control valve 4b to generate siphon in the toilet, and then closes the rim control valve 4a and the jet control valve 4b to seal the toilet. Can be prevented from filling. 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.

  Further, as illustrated in FIG. 14, 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. 10 and 13. It can be performed. That is, the control unit C opens the rim control valve 4a to supply water to the bowl surface of the toilet bowl, then closes the rim control valve 4a and the jet control valve 4b, and thereafter, the rim control valve 4a. The toilet bowl can be washed by opening the 4a and the jet control valve 4b. 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 instruction of FIG. 10 or 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.
FIG. 15 is a schematic view illustrating another configuration of the connection portions 5a and 5b and the string-like bodies 6a and 6b. This figure, like FIG. 8, 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. 16 illustrates the operation of the rotating body 5, the string-like bodies 6a and 6b, and the valves 4a and 4b when the connecting portions 5a and 5b and the string-like bodies 6a and 6b are configured as shown in FIG. FIG.
FIG. 17 is a schematic view illustrating the control mode of the valves 4a and 4b when the connecting portions 5a and 5b and the string-like bodies 6a and 6b are configured as shown in FIG.

  As shown in FIG. 15, the rim connection portion 5a and the jet connection portion 5b have an angle formed by the rim connection portion 5a, the rotation shaft 5s, and the jet connection portion 5b on the rotation surface is approximately 90 degrees. May be configured. For example, the connecting portion 5a can be disposed in the Z-axis negative direction with the rotation shaft 5s as the origin, and the connecting portion 5b can be disposed in the Y-axis positive direction.

  In this case, as shown in FIGS. 15A to 15C, the string-like bodies 6a and 6b are relaxed when the connecting portion 5a and the connecting portion 5b are in the ranges Ra and Rb, respectively, in the Z-axis direction. It becomes a state and it can be made to become a tension | tensile_strength if it deviates from these ranges.

  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. 16A, when the connecting portion 5a is in the vicinity of the lower end of the rotating track, for example, the string-like bodies 6a and 6b are in a relaxed state and the valves 4a and 4b are in a closed state. . As a result, the first state is realized.

  Also, as shown in FIG. 16B, when the connecting portion 5b is near the upper end of the rotating track, for example, the string-like body 6b is 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. 16C, when the connecting portion 5a is in the vicinity of the upper end of the rotating track, for example, only the string-like body 6a 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. 17 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. 17, in the time zone (1), the state becomes the first state according to the state of FIG. 17 (c). 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. 17 (e) and enters the third state. 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. 18 and 19.

  In the present embodiment, the connecting portions 5a and 5b are arbitrary as long as they can be reversibly switched directly or indirectly between the first state, the second state, and the third state. It can be provided in the position. When the string-like body 6 is used, the string-like bodies 6a and 6b and the ranges Ra and Rb are directly or directly between the first state, the second state, and the third state. As long as it can be switched indirectly and reversibly, it can be provided and set in any position / mode. That is, when both the rim string-like body 6a and the jet string-like body 6b are in a relaxed state (first state), at least the jet string-like body 6b is in a tension state that can open the jet control valve 4b. The case (second state) and the case where the rim string-like body 6a is in a tension state enough to open the rim control valve 4a and the jet string-like body 6b is in a relaxed state (third state) can be realized. As long as it can be provided and set in any position / mode. In the second state, when the jet control valve 4b is opened by the pushing operation described above, the rim control valve 4a is also opened at the same time, so that at least the jet string-like body 6b opens the jet control valve 4b. The second state can be realized if it is in a tension state that can be released.

Hereinafter, the case where the string-like body 6 is used will be described as an example.
18 and 19 are schematic views illustrating still another configuration of the connecting portions 5a and 5b and the string-like bodies 6a and 6b. As in FIG. 8, these drawings show 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 5a and 5b 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 5a and 5b may be the same or different.

  As shown in FIG. 18A, the rim connection portion 5a and the jet connection portion 5b may be provided at substantially the same position on the rotation surface. In this case, the timing at which each of the rim string-like body 6a and the jet string-like body 6b is in a tension state during the rotation of the rotating body 5 by making the lengths different (relatively shortening the rim string-like body 6a) or the like. Can be different. In other words, the upper end of the range Ra is set to be lower than the upper end of the range Rb. Thereby, the three states described above can be realized.

  That is, first, when both the rim string-like body 6a and the jet string-like body 6b are in the relaxed state, the first state is realized as shown in FIG. Thereafter, when the rotating body 5 rotates counterclockwise, as shown in FIG. 18B, the connecting portions 5a and 5b move to the Z axis positive side. In this case, since the rim string-like body 6a is relatively short, the rim string-like body 6a 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 5a and 5b further move to the Z-axis positive side, the jet string-like body 6b is also in a tensioned state. 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 5a and 5b move to the negative side of the Z axis, and the third state and the first state are in this order. Can be realized.

  Further, as shown in FIG. 19A, the rim connection portion 5a and the jet connection portion 5b are more detailed at positions on the line extending in the substantially same direction from the rotation shaft 5s and having different rotation radii. May be provided such that the radius of rotation of the rim connecting portion 5a is relatively large. Also in this case, as described above with reference to FIG. 18, the three states described above can be realized by making the lengths of the string-like bodies 6a and 6b different. Moreover, even if the lengths of the string-like bodies 6a and 6b are substantially the same, since the rotation radii of the connecting portions 5a and 5b are different, the timing when the string-like bodies 6a and 6b are in a tension state during the rotation of the rotating body 5 Can be different. That is, when the rotating body 5 rotates counterclockwise, as shown in FIG. 19B, the rim connecting portion 5a moves by a relatively large distance despite the movement by the same rotation angle (distance La> Distance Lb). As a result, the rim string 6a is in a tension state first. Thereafter, when the rotating body 5 further rotates counterclockwise and the connecting portions 5a and 5b further move to the Z-axis positive side, the jet string-like body 6b is also in a tensioned state. 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, similar operations can be realized by providing the connecting portions 5a and 5b at symmetrical positions with respect to the rotating shaft 5s and reversing the rotation.

Next, still another configuration of the toilet apparatus 1 according to the present embodiment will be described with reference to FIG.

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, usually, the cleaning water or the like can be supplied using the control unit C or the like, and the cleaning water or the like can be supplied manually using the tool T in the event of a power failure.

  In addition, although it demonstrated mainly using the siphon jet type flush toilet until now, the toilet apparatus which concerns on this embodiment is applicable to the arbitrary flush toilets which have two water supply channels.
