Japanese Patent Application Publication No. 2017-048552 Japanese Patent Application Publication No. 2021-127645

However, with conventional flush toilets as described above, when a user manually performs a toilet flushing operation during a power outage, it is difficult to determine which of the water supply part operation part and the on-off valve operation part should be operated last, and There is a possibility that the on-off valve operating section is operated instead of the water supply operation to the bowl section that should be performed in advance.

As described above, in the conventional flush toilet as described above, the procedure for manually flushing the toilet is difficult for the user to understand, and there is room for improvement from the viewpoint of improving operability.

One aspect of the embodiment is to provide a flush toilet that can improve operability when a user manually performs a toilet flushing operation.

A flush toilet according to one aspect of the embodiment includes a toilet main body having a bowl part and a drainage channel extending from the bowl part, an on-off valve that opens and closes a flow path of the drainage channel, and an operation of the on-off valve. a water supply section that can operate the water supply section; a water supply section that can operate the water supply section; It is used to operate the operating section, and enables the water supply section operating section to operate the on-off valve.

According to this configuration, since the on-off valve can be operated by the water supply unit operation unit, for example, when a user manually performs a toilet flushing operation during a power outage, the user can operate the water supply unit operation unit to supply water to the bowl unit. The operation can be performed by performing the operation and then closing the on-off valve. This allows you to manually flush the toilet, including supplying water to the bowl, closing the on-off valve, opening the on-off valve (with flushing water collected in the bowl), and the bowl. This makes it easier for the user to perform the water supply stop operation (water cutoff operation) to the section in a step-by-step manner. In this way, with this configuration, it is possible to improve the operability when the user manually performs the toilet flushing operation during a power outage or the like.

Furthermore, in the flush toilet described above, the water supply section operating section is provided so as to be connectable to the on-off valve operating section, and allows the on-off valve to be operated in a state where it is connected to the on-off valve operating section.

According to this configuration, since the on-off valve can be operated while the water supply section operation section is connected to the on-off valve operation section, the user can operate both the water supply section and the on-off valve from the water supply section operation section. It can be performed. Also, for example, when a user manually performs a toilet flushing operation during a power outage, the user can perform the operation by first supplying water to the bowl using the water supply operation section, and then closing the on-off valve. can. This allows you to manually flush the toilet, including supplying water to the bowl, closing the on-off valve, opening the on-off valve (with flushing water collected in the bowl), and the bowl. This makes it easier for the user to perform the water supply stop operation (water cutoff operation) to the section in a step-by-step manner. In this way, with this configuration, it is possible to improve the operability when the user manually performs the toilet flushing operation during a power outage or the like.

Further, in the flush toilet described above, the on-off valve operating section has an open position where the on-off valve is opened and a closed position where the on-off valve is closed, and the water supply section operating section is When the on-off valve operating section is in the valve open position, the connection with the on-off valve operating section is released.

According to this configuration, when the on-off valve operating section is in the open position, the connection between the water supply section operating section and the on-off valve operating section is released, so that the user can perform the toilet flushing operation with the on-off valve closed. This can prevent erroneous operations that would result in termination. Thereby, it is possible to improve the operability when the user manually performs a toilet flushing operation during a power outage or the like.

Further, in the flush toilet described above, the water supply section operation section has a water supply section side elongated member whose one end side is connected to the water supply section and the other end side extends from the toilet main body, The water supply section can be operated by pulling the elongated member on the side, and the on-off valve operation section is an on-off valve whose one end side is connected to the on-off valve and the other end side extends from the toilet main body. It has a side elongated member, and the on-off valve can be operated by pulling the on-off valve side elongated member, and the water supply side elongated member is closer to the toilet main body than the on-off valve side elongated member. It has a long length extending from.

According to this configuration, since the elongated member on the water supply side extends from the toilet main body longer than the elongated member on the on-off valve side, for example, when a user manually performs a toilet flushing operation during a power outage, The user can recognize that he or she must return the on-off valve operating section to the valve opening position before operating the water supply section (water shutoff operation). This allows you to perform operations such as supplying water to the bowl, closing the on-off valve, opening the on-off valve (with cleaning water collected in the bowl), and stopping the water supply to the bowl (water stop operation). This makes it easier for the user to follow the steps, and improves the operability when the user manually performs the toilet flushing operation during a power outage or the like.

Further, in the flush toilet described above, the on-off valve operation section includes a holding section that holds the on-off valve side elongated member by a predetermined amount of traction when the on-off valve side elongated member is towed.

According to this configuration, the holding part can hold the on-off valve side elongated member with a predetermined amount of traction, so that, for example, when the on-off valve side elongated member is pulled, the on-off valve is held in the closed state. When the on-off valve side elongated member is pulled again, the on-off valve can be opened. Therefore, the user does not need to continue pulling the on-off valve-side elongated member in order to keep the on-off valve closed. Thereby, it is possible to improve the operability when the user manually performs a toilet flushing operation during a power outage or the like.

Further, in the flush toilet described above, the on-off valve operating section has an operating end protruding from the toilet main body, and the on-off valve is operated by rotating the operating end in a predetermined operating direction. possible.

According to this configuration, since the on-off valve can be operated by rotating the operating end of the on-off valve operating section, a configuration that allows the on-off valve to be operated by the water supply section operating section can be realized with a simpler configuration. be able to. Thereby, it is possible to improve the operability when the user manually performs a toilet flushing operation during a power outage or the like.

According to one aspect of the embodiment, it is possible to improve the operability when a user manually performs a toilet flushing operation.

Hereinafter, embodiments of the flush toilet disclosed in the present application will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the embodiments described below.

<First embodiment>
<Configuration of flush toilet and toilet bowl body>
A flush toilet 1a and a toilet main body 10 according to a first embodiment will be described with reference to FIGS. 1A, 1B, and 2. 1A and 1B are schematic side sectional views showing a flush toilet 1a and a toilet main body according to the first embodiment. Note that FIG. 1A shows a state in which an on-off valve 1221, which will be described later, is opened. Moreover, FIG. 1B shows a state in which the on-off valve 1221 is closed. FIG. 2 is a diagram showing the overall configuration of the flush toilet 1a according to the first embodiment.

In addition, each figure, including FIGS. 1A and 1B, may show a three-dimensional orthogonal coordinate system including a Z axis whose positive direction is vertically upward (upward). Therefore, in the following, for convenience of explanation, the positive direction of the X-axis is defined as the left, the negative direction of the X-axis is defined as the right, the positive direction of the Y-axis is defined as the front, and the negative direction of the Y-axis is defined as the rear. The direction is called the left-right direction, the Y-axis direction is called the front-back direction, and the Z-axis direction is called the up-down direction.

As shown in FIGS. 1A and 1B, the flush toilet 1a includes a toilet main body 10. As shown in FIGS. The toilet main body 10 includes a bowl portion 11 and a drainage channel 12. The bowl portion 11 is a bowl-shaped portion that receives dirt. The bowl part 11 includes a rim spout 111 (see FIG. 2) that discharges washing water from a rim 13 formed at the upper part of the bowl part 11 to form a swirling flow of the washing water inside the bowl part 11. The bowl portion 11 also includes a jet spout 1121 that discharges cleaning water toward a trap line 121, which will be described later.

The drain path 12 is a flow path for discharging the waste received in the bowl part 11 to the external pipe 200, and includes a trap pipe 121 and a drain socket 122.

The trap line 121 communicates with the bottom of the bowl part 11 and extends rearward from the bowl part 11. Drainage socket 122 is provided downstream of trap line 121 and connects trap line 121 and external pipe 200.

The drain socket 122 is, for example, a floor drain type drain socket. The drain socket 122 includes an on-off valve 1221 and a rotating shaft 1222. The on-off valve 1221 is, for example, a flapper valve, and is provided in the flow path of the drain socket 122 to open and close the flow path of the drain socket 122. Note that the on-off valve 1221 may be other than a flapper valve as long as it is an on-off valve that can open and close the flow path of the drain channel 12 (drain socket 122). Moreover, although the on-off valve 1221 is provided in the drain socket 122 which is a part of the drain channel 12, it may be provided in the trap pipe line 121 which is a part of the drain channel 12.

The rotating shaft 1222 rotatably supports the on-off valve 1221. An on-off valve operating section 141a (see FIG. 2), which is an operating section manually operated by a user, is connected to the rotating shaft 1222 via an on-off valve side elongated member 142 (see FIG. 2).

One end of the on-off valve side elongated member 142 is connected to the on-off valve 1221, and the other end extends outward from the toilet main body 10. The on-off valve operating section 141a can operate the on-off valve 1221 by pulling the on-off valve side elongated member 142. Note that the on-off valve side elongated member 142 is, for example, a chain. Further, the on-off valve side elongated member 142 is not limited to a chain, and may be a wire such as a release wire, for example.

When the user manually performs an operation (pulling operation) on the on-off valve operating part 141a, such as pulling (pulling) the on-off valve operating part 141a, the on-off valve side elongated member 142 moves and rotates around the rotation axis. 1222 rotates in a predetermined direction. When the rotating shaft 1222 rotates in a predetermined direction, the on-off valve 1221 rotates and closes the flow path of the drain socket 122. Furthermore, when the user releases the pull on the on-off valve operating section 141a, the on-off valve side elongated member 142 moves, and the rotating shaft 1222 rotates in the opposite direction to the predetermined direction. When the rotating shaft 1222 rotates in the opposite direction, the on-off valve 1221 rotates and opens the flow path of the drain socket 122.

Note that the on-off valve 1221 does not need to completely close the flow path of the drain channel 12 (drain socket 122). That is, since it is sufficient that the water level inside the bowl part 11 can be raised above the initial water level by the cleaning water discharged from the rim spout 111 (and/or the jet spout 112), the opening/closing valve 1221 and the drain socket 122 are There may be some gap between the inner surface and the inner surface.

As shown in FIG. 2, the flush toilet 1a includes a water supply section 300. The water supply unit 300 is arranged, for example, at the rear of the toilet main body 10. The water supply section 300 is connected to an external power source (not shown), and when there is no power outage, water is supplied to the bowl section 11 by driving components such as a solenoid valve using external power supplied from the external power source. Supply wash water.

The water supply unit 300 includes a constant flow valve 301, a solenoid valve 302, and a rim water discharge vacuum breaker 303. The water supply channel 304 of the water supply unit 300 includes a water storage tank 305, a switching valve 306 for switching between water supply to the water storage tank 305 and rim water discharge, a pressure pump 307, a jet water discharge vacuum breaker 308, and a drain valve 309. will be provided. Further, the water supply unit 300 is provided with a control unit 310 that controls the opening/closing operation of the electromagnetic valve 302, the switching operation of the switching valve 306, the pressurizing operation of the pressure pump 307, and the like.

The constant flow valve 301 throttles the wash water that has flowed in through the drain plug 311, the strainer 312, and the branch fitting 313 to a predetermined flow rate or less. The cleaning water that has passed through the constant flow valve 301 flows into the electromagnetic valve 302 , and the cleaning water that has passed through the electromagnetic valve 302 is supplied to the rim spout 111 or the water storage tank 305 by the switching valve 306 .

The electromagnetic valve 302 is a diaphragm type electromagnetic on-off valve that opens and closes under the control of the control unit 310. A diaphragm 314 is provided in the water supply channel 304, and a pressure chamber 315 is provided adjacent to the diaphragm 314. The solenoid valve 302 operates the diaphragm 314 by changing the pressure in the pressure chamber 315, thereby controlling the flow of cleaning water in the water supply channel 304.

The switching valve 306 causes the wash water that has flowed in through the electromagnetic valve 302 to be discharged from the rim spout 111 or to flow into the water storage tank 305 .

The rim water spout vacuum breaker 303 is disposed in the middle of the rim side water supply channel 316 that guides the wash water that has passed through the switching valve 306 to the rim water spout 111, and prevents the wash water from flowing back from the rim water spout 111. Further, the rim water discharge vacuum breaker 303 is arranged above the upper surface of the bowl portion 11 to reliably prevent backflow. Further, the wash water overflowing from the atmosphere opening part of the rim water discharge vacuum breaker 303 flows through the return pipe 317 and flows into the water storage tank 305 via the float type check valve 318.

The water storage tank 305 stores cleaning water to be spouted from the jet spout 112 .

Further, for example, the tip (lower end) of the tank-side water supply channel 319 is connected to a float type check valve 320 to prevent backflow from the water storage tank 305 to the tank-side water supply channel 319. Furthermore, an upper end float switch 321 and a lower end float switch 322 are arranged inside the water storage tank 305 so that the water level of the water storage tank 305 can be detected. The upper end float switch 321 is turned on when the water level of the water storage tank 305 reaches a predetermined water storage level, and the control unit 310 closes the solenoid valve 302. On the other hand, the lower end float switch 322 is turned on when the water level in the water storage tank 305 drops to a predetermined water level, and the control unit 310 stops the pressure pump 307.

The pressurizing pump 307 pressurizes the cleaning water stored in the water storage tank 305 and discharges it from the jet spout 112 . The pressurizing pump 307 is connected by a pump-side water supply channel 323 extending from the water storage tank 305 and pressurizes the wash water stored in the water storage tank 305.

The water drain plug 311 is arranged near the lower end of the water storage tank 305 and below the pressure pump 307. Therefore, by opening the drain valve 311, the cleaning water from the water storage tank 305 and the pressure pump 307 can be discharged during maintenance or the like. Further, a water receiving tray 324 is arranged below the pressure pump 307. The water receiving tray 324 receives condensed water droplets and water leakage.

On the other hand, the outlet of the pressurizing pump 307 is connected to the jet spout 112 at the bottom of the bowl portion 11 via the jet side water supply channel 325. The midway of the jet side water supply channel 325 is formed in a convex shape toward the top, and the highest part of the convex portion, the jet side water supply channel top 325a, is a cleaning water pipe from the water storage tank 305 to the jet spout 112. This is the highest part of the road. Further, the downstream side of the jet side water supply channel 325 from the jet side water supply channel top portion 325a is set at the same height as the jet water spout 112.

An overflow channel 326 having an overflow port 326a at one end is connected to the jet side water supply channel 325. The overflow port 326a is provided above the upper end float switch 321. When the water level in the water storage tank 305 becomes higher than the upper end float switch 321, the water in the water storage tank 305 flows into the overflow channel 326 from the overflow port 326a, is pressurized by the pressure pump 307, and the water in the water storage tank 305 flows into the overflow channel 326 from the overflow port 326a, and is pressurized by the pressure pump 307. It is discharged from the jet spout 112 via the valve 327.

The jet water discharge vacuum breaker 308 is disposed in the middle of the tank-side water supply channel 319 that guides the wash water that has passed through the switching valve 306 to the water storage tank 305, and prevents the wash water from flowing back from the water storage tank 305. Washing water overflowing from the atmosphere opening part of the jet water discharge vacuum breaker 308 flows through the return pipe 317 and flows into the water storage tank 305 via the float type check valve 318.

The control unit 310 sequentially operates the solenoid valve 302, the switching valve 306, and the pressurizing pump 307 in response to the user's operation of a toilet flushing switch (not shown), thereby discharging water from the rim spout 111 and the jet spout 112. The bowl portion 11 is cleaned by starting in sequence. Further, after the cleaning is completed, the control unit 310 opens the solenoid valve 302 and switches the switching valve 306 to the water storage tank 305 side to replenish the water storage tank 305 with cleaning water. When the water level in the water storage tank 305 rises and the upper end float switch 321 detects a specified water storage amount, the control unit 310 closes the electromagnetic valve 302 to stop water supply.

As shown in FIG. 2, the switching unit 329 that switches between supplying washing water and stopping water supply (water stop) by the water supply unit 300 is provided with a water supply unit operation unit 151 that is manually operated by the user. The water supply section operation section 151 includes a water supply section side elongated member 152.

One end of the water supply part side elongated member 152 is connected to the switching part 329, and the other end extends outward from the toilet main body 10. The water supply unit operation unit 151 is capable of supplying water to the water supply unit 300 and stopping the water supply (water cutoff) by pulling the water supply unit side elongated member 152. Note that the water supply section side elongated member 152 is, for example, a bead chain. Moreover, the water supply part side elongated member 152 is not limited to a chain, and may be a wire such as a release wire, for example.

When the user performs a manual operation (pulling operation) on the water supply unit operation unit 151, such as pulling (pulling) the water supply unit operation unit 151, the water supply unit side elongated member 152 moves, and the switching unit Activate 329. Furthermore, the switching section 329 has a knocking structure described in, for example, Japanese Patent Application Laid-open No. 2022-011904, and when the water supply section side elongated member 152 is towed, the water supply state is maintained by one traction. , switch to water stop state by towing again. Therefore, the user does not need to continue pulling the water supply section side elongated member 152 while supplying cleaning water.

Further, as shown in FIG. 2, the on-off valve operating section 141a includes a holding section 143. The holding portion 143 is provided on the on-off valve side elongated member 142. Although not shown, the holding part 143 has a knocking mechanism incorporated therein, and holds the on-off valve side elongated member 142 by a predetermined amount of traction when the on-off valve side elongated member 142 is pulled.

<Installation location of on-off valve operation unit and water supply unit operation unit>
Next, the installation location Ar of the on-off valve operating section 141a and the water supply section operating section 151 will be described with reference to FIG. FIG. 3 is an explanatory diagram of the installation location Ar of the on-off valve operating section 141a and the water supply section operating section 151. Note that FIG. 3 shows a schematic perspective view of the toilet main body 10 when viewed from the rear.

As shown in FIG. 3, the flush toilet 1a includes a sanitary cleaning device 16 capable of cleaning the private parts of the user's body. The sanitary cleaning device 16 includes a toilet seat, a toilet lid (both not shown), and is installed on the top surface of the toilet main body 10. The main body portion 161 of the sanitary cleaning device 16 is arranged at the rear of the toilet main body 10. Note that the sanitary washing device 16 may not include a toilet lid.

As shown in FIG. 3, the installation location Ar of the on-off valve operating section 141a and the water supply section operating section 151 is set at the upper and rear portion of the toilet main body 20. That is, the on-off valve operating section 141a and the water supply section operating section 151 are arranged close to each other in the same installation location Ar.

Further, the on-off valve operating section 141a and the water supply section operating section 151 are housed inside the rear cover 162 of the sanitary cleaning device 16 so as not to be visible from the outside. Therefore, when operating the on-off valve operating section 141a and the water supply section operating section 151, the user opens the rear cover 162 and then performs each manual operation.

<Operation of the on-off valve operating section and water supply section operating section>
Next, the operations of the on-off valve operating section 141a and the water supply section operating section 151 will be described with reference to FIG. FIG. 4 is an explanatory diagram of the operation of the on-off valve operating section 141a and the water supply section operating section 151. Note that FIG. 4 shows (a) the operation in the case of water supply operation, (b) the operation in the case of connecting the water supply unit operation part 151 to the on-off valve operation part 141a, (c) the operation in the case of valve closing operation, ( d) Operation in case of valve opening operation, (e) Operation in case of water shutoff operation.

First, as shown in FIG. 4(a), in the case of water supply operation, the water supply section operation section 151 is pulled upward and the water supply section operation section 151 (water supply section side elongated member 152) is pulled.

Next, as shown in FIG. 4(b), the water supply section operating section 151 is connected to the on-off valve operating section 141a. In addition, when connecting the water supply part operation part 151 with the on-off valve operation part 141a, the user can perform engagement and disengagement with one hand, for example, by the engagement structure described below. An example of such an engagement structure will be described later using FIGS. 8 and 9.

Next, as shown in FIG. 4(c), in the case of a valve closing operation, the water supply section operating section 151 pulled out by the user pulls out the on-off valve operating section 141a. Thereby, the on-off valve operating section 141a moves to the valve-closing position P1 where the on-off valve 1221 (see FIGS. 1A and 1B) is closed. Next, as shown in FIG. 4(d), in the case of a valve opening operation, when cleaning water accumulates in the bowl part 11 (see FIGS. 1A and 1B), the water supply part operating part 151 releases the on-off valve operating part 141a from pulling. be done.

As shown in FIG. 4(e), in the case of water shutoff operation, after returning the on-off valve operating section 141a to the original position (valve open position P2), the water supply section operating section 151 supplies water at the valve open position P2. The connection (engagement) between the section operation section 151 and the on-off valve operation section 141a is released. When the connection with the on-off valve operating section 141a is released, the water supply section operating section 151 is returned to its original position. This completes the water shutoff operation.

In this way, the water supply section operation section 151 is used to operate the on-off valve operation section 141a to open and close the on-off valve 1221 (see FIGS. 1A and 1B). In this case, the water supply section operation section 151 and the on-off valve operation section 141a are connected, and the on-off valve 1221 is operated by the water supply section operation section 151 while connected to the on-off valve operation section 141a.

Further, the water supply section side elongated member 152 is provided so as to extend from the toilet main body 10 (see FIGS. 1A and 1B) longer than the on-off valve side elongated member 142. In this way, since the water supply part side elongated member 152 extends from the toilet main body 10 longer than the on-off valve side elongated member 142, water is supplied after returning the on-off valve operation part 141a to the valve opening position P2. The user can be made aware of the need to operate the section 300 (see FIG. 2) (water shutoff operation).

Furthermore, by making the on-off valve operating section 141a smaller than the water supply section operating section 151, it is possible to guide the user to operate the water supply section operating section 151 with priority. In addition, by reducing the amount of protrusion of the on-off valve operating portion 141a from the main body portion 161 of the sanitary washing device 16, or by eliminating the amount of protrusion of the on-off valve operating portion 141a from the main body portion 161 of the sanitary washing device 16, the user can However, it is possible to prevent the on-off valve operating section 141a from being erroneously operated before the water supply section operating section 151.

<Engagement structure of on-off valve operating section and water supply section operating section>
Next, the engagement structure of the on-off valve operating section 141a and the water supply section operating section 151 will be described with reference to FIGS. 5 and 6. 5 and 6 are explanatory diagrams of an example of the engagement structure of the on-off valve operating section 141a and the water supply section operating section 151. Note that FIG. 5 shows a schematic side cross section showing the engagement structure. Further, FIG. 6 shows (a) a schematic side cross section in an engaged state, and (b) a schematic side cross section in a disengaged state.

As shown in FIG. 5 , in an example of the engagement structure, the water supply unit operating section 151 includes an outer peripheral section 21 , a pressing section 22 , a rod section 23 , a biasing member 24 , and a ball 25 . The outer peripheral portion 21 is formed in a cylindrical shape. The outer circumferential portion 21 forms the outer circumferential surface of the water supply section operating section 151. The outer peripheral portion 21 has a distal end thereof serving as an engagement convex portion 211 that is inserted into an engagement recess 26 described later. Further, a hole 212 is formed at the tip of the outer circumferential portion 21 to hold a ball 25, which will be described later, so as to be movable toward the outside.

The pressing portion 22 is formed in a cylindrical shape and is provided so as to be inserted into the outer peripheral portion 21 . The rod portion 23 is formed in a cylindrical shape having a diameter smaller than that of the pressing portion 22, and is provided so as to extend downward from the pressing portion 22. A flange 231 is provided at the tip of the rod portion 23 to prevent it from coming off. Furthermore, a constricted portion 232 is formed at the tip of the rod portion 23 by a tapered surface 232a.

The biasing member 24 is, for example, a coil spring, and is provided between the inner surface of the outer peripheral portion 21 and the pressing portion 22, and biases the pressing portion 22 (and the rod portion 23) upward.

The ball 25 is placed in the constriction 232 of the rod portion 23 . The ball 25 is pushed outward by the tapered surface 232a of the constricted part 232 as the pressing part 22 and the rod part 23 move (sliding) upward, and is engaged by protruding outward from the hole 212. The diameter of the convex portion 211 is expanded. In addition, the ball 25 is accommodated in the constricted portion 232 as the pressing portion 22 and the rod portion 23 move (slide) downward, thereby returning the engagement convex portion 211 to its original diameter.

Further, in an example of the engagement structure, the on-off valve operating section 141a includes an engagement recess 26. A tapered surface 261 whose diameter decreases upward is formed on the inner circumferential surface of the engagement recess 26 . When the engagement protrusion 211 is inserted into the engagement recess 26, the tapered surface 261 sandwiches the ball 25 between it and the tapered surface 232a of the constriction 232.

As shown in FIG. 6(a), when the water supply unit operating section 151 is pulled upward with the engagement protrusion 211 inserted into the engagement recess 26, the ball 25 protrudes from the hole 212 and engages. It is sandwiched between the tapered surface 261 of the concave portion 26 and the tapered surface 232a of the constricted portion 232, and the engaged state of the engagement convex portion 211 and the engagement concave portion 26 is maintained.

As shown in FIG. 6(b), when the pressing part 22 is pressed from above, the ball 25 is accommodated in the constricted part 232 as the pressing part 22 and the rod part 23 move (slide) downward. Therefore, the engagement protrusion 211 returns to its original diameter, and the engaged state between the engagement protrusion 211 and the engagement recess 26 is released.

As described above, in one example of the engagement structure, the engagement between the engagement convex portion 211 and the engagement recess 26 allows the water supply section operation section 151 and the on-off valve operation section 141a to be easily engaged and disengaged. It can be done with Note that the above-described engagement structure is an example, and the present invention is not limited to this engagement structure. Further, by forming the engagement protrusion and the engagement recess with unevenness made of resin or rubber, for example, a simple engagement structure can be achieved.

<Flow of flushing water during manual toilet flushing operation>
Next, with reference to FIG. 7, the flow of flushing water in the manual toilet bowl flushing operation will be described. FIG. 7 is an explanatory diagram of the flow of flushing water in a manual toilet flushing operation. Note that Figure 7 shows (a) the flow of cleaning water due to the water supply operation, (b) the flow of cleaning water due to the valve closing operation, (c) the flow of cleaning water due to the valve opening operation, and (d) the cleaning due to the water shutoff operation. It shows the flow of water.

As shown in FIG. 7A, when a user performs a water supply operation by pulling the water supply unit operation unit 151, cleaning water is supplied to the bowl unit 11. Next, as shown in FIG. 7(b), when the user pulls the water supply section operation section 151 and the on-off valve operation section 141a upward to perform a valve opening operation, the on-off valve 1221 closes and the cleaning water is released. However, cleaning water begins to accumulate in the bowl portion 11.

Here, whether or not the on-off valve 1221 is opened can be confirmed by the click feeling of the holding part 143 (see FIG. 2). Further, since the amount of traction of the on-off valve side elongated member 142 is maintained by the holding portion 143, the on-off valve 1221 is maintained in the closed state even if the user loosens the pulling force. Further, the user visually checks whether or not cleaning water has accumulated in the bowl portion 11.

When the cleaning water accumulates in the bowl part 11, the user releases the closed state held by the holding part 143 and opens the on-off valve 1221.

Next, as shown in FIG. 7(c), the washing water in the bowl part 11 flows into the drain channel 12, and the waste in the bowl part 11 is discharged through the drain channel 12.

Then, as shown in FIG. 7(d), when the user performs a water stop operation by returning the water supply section operation section 151 to its original position, the washing water stops flowing to the bowl section 11.

As described above, according to the flush toilet 1a according to the first embodiment, the on-off valve 1221 can be operated by the water supply unit operation section 151, so that, for example, when a user manually performs a toilet flushing operation during a power outage. , the user can operate the water supply section operation section 151 to supply water to the bowl section 11 and then close the on-off valve 1221. As a result, operations when manually flushing the toilet bowl, that is, supplying water to the bowl part 11, closing the on-off valve 1221, and opening the on-off valve 1221 (with flushing water collected in the bowl part 11), can be performed manually. The user can easily perform the valve operation and the water supply stop operation (water cutoff operation) to the bowl portion 11 in sequence. In this way, with this configuration, it is possible to improve the operability when the user manually performs the toilet flushing operation during a power outage or the like.

In addition, since the on-off valve 1221 can be operated while the water supply section operation section 151 is connected to the on-off valve operation section 141a, the user can operate the water supply section 300 and the on-off valve 1221 from the water supply section operation section 151. You can do both. For example, when the user manually performs a toilet flushing operation during a power outage, the user performs the operation by first supplying water to the bowl part 11 using the water supply part operation part 151, and then closing the on-off valve 1221. It can be carried out. As a result, operations when manually flushing the toilet bowl, that is, supplying water to the bowl part 11, closing the on-off valve 1221, and opening the on-off valve 1221 (with flushing water collected in the bowl part 11), can be performed manually. The user can easily perform the valve operation and the water supply stop operation (water cutoff operation) to the bowl portion 11 in sequence. In this way, with this configuration, it is possible to improve the operability when the user manually performs the toilet flushing operation during a power outage or the like.

In addition, when the on-off valve operating section 141a is at the open position P2, the water supply section operating section 151 and the on-off valve operating section 141a are disconnected, so the user can perform the toilet flushing operation with the on-off valve 1221 closed. This can prevent erroneous operations such as terminating the program. Thereby, it is possible to improve the operability when the user manually performs a toilet flushing operation during a power outage or the like.

In addition, since the water supply side elongated member 152 extends from the toilet main body 10 longer than the on-off valve side elongated member 142, for example, when a user manually performs a toilet flushing operation during a power outage, the elongated member 152 is not used. The person can recognize that the water supply unit 300 must be operated (water cutoff operation) after returning the on-off valve operation unit 141a to the valve opening position P2. As a result, water can be supplied to the bowl part 11, the on-off valve 1221 can be closed, the on-off valve 1221 can be opened (with cleaning water accumulated in the bowl part 11), and the water supply to the bowl part 11 can be stopped (stopped). This makes it easier for the user to perform the water operation step by step, and improves the operability when the user manually performs the toilet flushing operation during a power outage or the like.

Further, since the holding part 143 can hold the on-off valve side elongated member 142 with a predetermined amount of traction, for example, when the on-off valve side elongated member 142 is pulled, the on-off valve 1221 is held in the closed state. When the on-off valve side elongated member 142 is pulled again, the on-off valve 1221 can be opened. Therefore, the user does not need to continue pulling the on-off valve side elongated member 142 in order to keep the on-off valve 1221 in the closed state. Thereby, it is possible to improve the operability when the user manually performs a toilet flushing operation during a power outage or the like.

<Second embodiment>
<Configuration of flush toilet and toilet bowl body>
Next, a flush toilet 1b according to a second embodiment will be described with reference to FIG. 8. FIG. 8 is a diagram showing the overall configuration of a flush toilet 1b according to the second embodiment.

The second embodiment described below differs from the first embodiment described above in the configuration of an on-off valve operating section 141b. Therefore, in the description of the second embodiment, the same or equivalent parts as in the first embodiment are given the same reference numerals, and the description of the same parts is omitted.

As shown in FIG. 8, the on-off valve operating section 141b includes an operating end section 141ba. The operating end portion 141ba protrudes outward (upward) from the toilet main body 10. The on-off valve operating section 141b is capable of operating the on-off valve 1221 by rotating the operating end 141ba around an axis in a predetermined operating direction D by a predetermined angle.

<Operation of the on-off valve operating section and water supply section operating section>
Next, the operations of the on-off valve operating section 141b and the water supply section operating section 151 will be described with reference to FIG. FIG. 9 is an explanatory diagram of the operation of the on-off valve operating section 141b and the water supply section operating section 151. In addition, FIG. 9 shows (a) the operation in the case of water supply operation, (b) the operation in the case of connecting the water supply unit operation part 151 to the on-off valve operation part 141b, (c) the operation in the case of valve closing operation, ( d) Operation in case of valve opening operation, (e) Operation in case of water shutoff operation.

First, as shown in FIG. 9(a), in the case of water supply operation, the water supply section operation section 151 is pulled upward and the water supply section operation section 151 (water supply section side elongated member 152) is pulled.

Next, as shown in FIG. 9(b), the water supply section operating section 151 is connected to the on-off valve operating section 141b. In addition, when connecting the water supply part operation part 151 with the on-off valve operation part 141b, the above-described engagement structure allows the user to engage and disengage with one hand, for example.

Next, as shown in FIG. 9C, in the case of a valve closing operation, the on-off valve operating section 141b rotates in the operating direction D1 while being connected to the water supply section operating section 151. As a result, the on-off valve operating section 141b moves (rotates) to the closing position where the on-off valve 1221 (see FIGS. 1A and 1B) is closed.

Next, as shown in FIG. 9(d), in the case of a valve opening operation, when cleaning water accumulates in the bowl part 11 (see FIGS. 1A and 1B), the on-off valve operating part 141b is connected to the water supply part operating part 151. It rotates in the operating direction D2 in this state. Thereby, the on-off valve operating section 141b moves (rotates) to the valve-opening position where the on-off valve 1221 (see FIGS. 1A and 1B) is opened.

As shown in FIG. 9(e), in the case of water shutoff operation, after returning the on-off valve operating section 141b to its original position (valve open position), the water supply section operating section 151 operates the water supply section at the valve open position. The connection (engagement) between the section 151 and the on-off valve operating section 141b is released. When the connection with the on-off valve operating section 141b is released, the water supply section operating section 151 is returned to its original position. This completes the water shutoff operation.

In this way, the water supply section operation section 151 is used to operate the on-off valve operation section 141b to open and close the on-off valve 1221 (see FIGS. 1A and 1B). In this case, the water supply section operation section 151 and the on-off valve operation section 141b are connected, and the on-off valve 1221 is operated by the water supply section operation section 151 while connected to the on-off valve operation section 141b.

Note that, for example, a fixing member having a notch in a part of an annular ring and having a C-shape in plan view can also be provided in the on-off valve operating portion 141b. In this case, the notch is configured to have a width that allows a protrusion provided to protrude outward from the outer circumferential surface of the water supply unit operation part 151 to pass through in the vertical direction. For example, as shown in FIG. In this state, the water supply section operating section 151 and the on-off valve operating section 141b can be fixed so that they cannot be separated.

<Flow of flushing water during manual toilet flushing operation>
Next, with reference to FIG. 10, the flow of flushing water in the manual toilet flushing operation will be described. FIG. 10 is an explanatory diagram of the flow of flushing water in a manual toilet flushing operation. Note that FIG. 10 shows (a) the flow of cleaning water due to the water supply operation, (b) the flow of cleaning water due to the valve closing operation, (c) the flow of cleaning water due to the valve opening operation, and (d) the cleaning due to the water shutoff operation. It shows the flow of water.

As shown in FIG. 10A, when the user performs a water supply operation by pulling the water supply unit operation unit 151, cleaning water is supplied to the bowl unit 11. Next, as shown in FIG. 10(b), when the user performs a valve opening operation by rotating the on-off valve operating section 141b in the operating direction D1 using the water supply section operating section 151, the on-off valve 1221 closes. Cleaning water begins to accumulate in the bowl portion 11.

When the cleaning water accumulates in the bowl part 11, the user opens the on-off valve 1221 by rotating the on-off valve operating part 141b in the operating direction D2 using the water supply part operating part 151.

Next, as shown in FIG. 10(c), the washing water in the bowl section 11 flows into the drain channel 12, and the waste in the bowl section 11 is discharged through the drain channel 12.

Then, as shown in FIG. 10(d), when the user performs a water stop operation by returning the water supply section operation section 151 to its original position, the washing water stops flowing into the bowl section 11.

As described above, according to the flush toilet 1b according to the second embodiment, the on-off valve 1221 can be operated by the water supply unit operation section 151, so that, for example, when a user manually performs a toilet flushing operation during a power outage. , the user can operate the water supply section operation section 151 to supply water to the bowl section 11 and then close the on-off valve 1221. As a result, operations when manually flushing the toilet bowl, that is, supplying water to the bowl part 11, closing the on-off valve 1221, and opening the on-off valve 1221 (with flushing water collected in the bowl part 11), can be performed manually. The user can easily perform the valve operation and the water supply stop operation (water cutoff operation) to the bowl portion 11 in sequence. In this way, with this configuration, it is possible to improve the operability when the user manually performs the toilet flushing operation during a power outage or the like.

In addition, since the on-off valve 1221 can be operated while the water supply section operation section 151 is connected to the on-off valve operation section 141b, the user can operate the water supply section 300 and the on-off valve 1221 from the water supply section operation section 151. You can do both. For example, when the user manually performs a toilet flushing operation during a power outage, the user performs the operation by first supplying water to the bowl part 11 using the water supply part operation part 151, and then closing the on-off valve 1221. It can be carried out. As a result, operations when manually flushing the toilet bowl, that is, supplying water to the bowl part 11, closing the on-off valve 1221, and opening the on-off valve 1221 (with flushing water collected in the bowl part 11), can be performed manually. The user can easily perform the valve operation and the water supply stop operation (water cutoff operation) to the bowl portion 11 in sequence. In this way, with this configuration, it is possible to improve the operability when the user manually performs the toilet flushing operation during a power outage or the like.

Further, when the on-off valve operating section 141b is in the open position, the water supply section operating section 151 and the on-off valve operating section 141b are disconnected, so the user can perform the toilet flushing operation with the on-off valve 1221 closed. This can prevent erroneous operations that would result in termination. Thereby, it is possible to improve the operability when the user manually performs a toilet flushing operation during a power outage or the like.

In addition, since the on-off valve 1221 can be operated by rotating the operating end 141ba of the on-off valve operating section 141b, a simpler configuration allows the on-off valve 1221 to be operated by the water supply section operating section 151. can do. Thereby, it is possible to improve the operability when the user manually performs a toilet flushing operation during a power outage or the like.

In the above-described embodiment, the water supply section operation section 151 and the on-off valve operation section 141a are operated by a towing operation, or the water supply section operation section 151 is operated by a towing operation, and the on-off valve operation section 141b is operated by a rotation operation.
