Description

[Technical Field]

[0001] The present invention relates to a flush toilet, and more particularly to a flush toilet that is flushed with flush water to expel waste. [Background technology]

[0002] BACKGROUND ART Conventionally, as flush toilets that are cleaned with flush water to discharge waste, there are known ones that allow water supply and drainage operations for the toilet body during a power outage, as described in Patent Documents 1 and 2, for example. First, the conventional flush toilet described in Patent Document 1 above is equipped with a single operating unit that is used in common for both the water supply and flush operations during a power outage. For example, during a power outage, manually pulling up a wire that is part of this operating unit a predetermined amount changes the valve body that opens and closes the flow path in the drain socket downstream of the toilet body from an open state to a closed state. Furthermore, by pulling up the operating unit a predetermined amount, power is supplied from an emergency battery or a large-capacity capacitor to the solenoid valve of the water supply device that supplies flush water to the toilet body, opening the solenoid valve and supplying water to the toilet body. Then, by releasing the force pulling the operating unit again, the valve body that opens and closes the flow path in the drain socket changes from a closed state to an open state, allowing flush water to be drained from the flow path upstream of the valve body and within the bowl of the toilet body. Next, in the conventional flush toilet described in Patent Document 2 mentioned above, the water supply operation unit and the drain operation unit, which respectively perform the water supply operation and the drain operation during a power outage, are installed independently in separate locations. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-227080 [Patent Document 2] Patent Publication No. 2021-38635 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in recent years, there has been an increasing demand for flush toilets that can be flushed without relying on power from an emergency battery or the like, as a countermeasure against power outages that occur in emergencies such as disasters. Furthermore, during a power outage, lighting and other equipment cannot be used, and users must perform cleaning operations that differ from normal operations by feel, making it difficult to grasp the location and operating procedures of each control part for water supply and drainage operations, resulting in the problem that it is not easy to perform appropriate operations during a power outage. Therefore, in recent years, a pressing issue has arisen regarding how users can quickly grasp the location and operation procedures of each control part for water supply and drainage operations when performing water supply and drainage operations during a power outage, and how to simplify complicated power outage operations and perform appropriate power outage operations.

[0005] Therefore, the present invention was made to solve the problems with the prior art mentioned above and the issues that have been required in recent years, and its object is to provide a flush toilet that allows for easy and appropriate water supply and drainage operations during a power outage. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the present invention provides a flush toilet that is flushed with flush water and discharges waste, comprising a toilet body having a bowl portion that receives waste and a drain trap portion that discharges the waste within the bowl portion, and a functional portion including a water supply unit that is provided behind the bowl portion of the toilet body and supplies flush water to the toilet body, the water supply unit having a water supply passage that connects the toilet body to a water supply source and an on-off valve that opens and closes the water supply passage, the on-off valve opening and closing to enable the supply and stopping of flush water to be supplied to the toilet body, a drain socket portion that is provided downstream of the drain trap portion of the toilet body, and a flow path that is provided inside the drain socket portion and a power outage water supply operation unit that manually opens and closes the on-off valve of the water supply unit during a power outage, thereby enabling the water supply to the toilet body to be stopped; and a power outage drain operation unit that manually opens and closes the socket opening and closing unit during a power outage, thereby enabling the drainage operation from the drain socket unit and the storage of water in the bowl unit, wherein the power outage water supply operation unit and the power outage drain operation unit are each provided at the same location on the functional unit in a non-operated state, and the power outage water supply operation unit in a non-operated state is arranged in the direction of its operation axis, while the power outage drain operation unit in a non-operated state is arranged in a different operation axis direction from the operation axis direction. In the present invention configured in this manner, the power outage water supply operation unit and the power outage drainage operation unit in the non-operating state are each located in the same location on the functional unit, so even when the user performs a power outage operation that is different from normal operations, the user can easily grasp the locations of the two operation units, the power outage water supply operation unit and the power outage drainage operation unit, thereby reducing the effort required when starting power outage operations. Furthermore, while the water supply operation unit during a power outage when not in operation is arranged in the direction of the operation axis, the drainage operation unit during a power outage when not in operation is arranged in a different direction of the operation axis relative to the direction of the operation axis.As a result, of the two water supply operation units during a power outage and the drainage operation unit during a power outage that are provided at the same location in the functional unit, only the drainage operation unit during a power outage can be arranged in a different direction of the operation axis relative to the operation axis. This makes it easier for the user to understand the respective positions of the two operating parts with different functions, thereby making it possible to prevent erroneous operations. Furthermore, by arranging the power outage water supply operation unit, which has a higher priority for power outage operation than the power outage drain operation unit, in the direction of the operating axis, it becomes easier for the user to perform the water supply stop operation using the power outage water supply operation unit than to perform the drain operation using the power outage drain operation unit. Furthermore, during a power outage, the user can be guided to prioritize the water supply operation using the power outage water supply operating unit over the drainage operation using the power outage drainage operating unit. As a result, users can easily understand the two operating procedures during a power outage, namely, the water supply operation using the power outage water supply operation unit and the drainage operation using the power outage drainage operation unit, which are different from normal operations.This allows users to properly perform power outage operations using both the power outage water supply operation unit and the power outage drainage operation unit, and simplifies complicated power outage operations.

[0007] The present invention also provides a flush toilet that is preferably flushed with flush water and discharges waste, comprising a toilet body having a bowl portion that receives waste and a drain trap portion that discharges the waste within the bowl portion, and a functional portion including a water supply unit that is provided behind the bowl portion of the toilet body and supplies flush water to the toilet body, the water supply unit having a water supply channel that connects the toilet body to a water supply source and an on-off valve that opens and closes the water supply channel, the on-off valve opening and closing to enable the supply and stop of flush water to be supplied to the toilet body, a drain socket portion provided downstream of the drain trap portion of the toilet body, and The toilet is provided with a socket opening / closing section provided inside for opening and closing the flow path, a power outage water supply operation section which manually opens and closes the opening / closing valve of the water supply unit during a power outage to enable water supply and stopping to the toilet body, and a power outage drain operation section which manually opens and closes the socket opening / closing section during a power outage to enable drainage from the drain socket section and storage of water in the bowl section, wherein the power outage water supply operation section and the power outage drain operation section are each provided in the same location on the functional section when in a non-operated state, and the power outage water supply operation section when in a non-operated state is located higher than the power outage drain operation section when in a non-operated state. In the present invention configured in this manner, the power outage water supply operation unit and the power outage drainage operation unit in the non-operating state are each located in the same location on the functional unit, so even when the user performs a power outage operation that is different from normal operations, the user can easily grasp the locations of the two operation units, the power outage water supply operation unit and the power outage drainage operation unit, thereby reducing the effort required when starting power outage operations. Furthermore, by positioning the power outage water supply operation unit in the non-operating state higher than the power outage drainage operation unit in the non-operating state, the two power outage water supply operation units and the power outage drainage operation units, which are provided in the same location on the functional unit, can be positioned at different height positions. This makes it easier for the user to understand the respective positions of the two operating parts with different functions, thereby making it possible to prevent erroneous operations. Furthermore, by placing the power outage water supply operation unit, which has a higher priority for power outage operation, above the power outage drainage operation unit, it becomes easier for users to access the power outage water supply operation unit than the power outage drainage operation unit, making it easier to perform water supply stop operations using the power outage water supply operation unit than to perform drainage operations using the power outage drainage operation unit. Furthermore, during a power outage, the user can be guided to prioritize the water supply operation using the power outage water supply operating unit over the drainage operation using the power outage drainage operating unit. As a result, users can easily understand the two operating procedures during a power outage, namely, the water supply operation using the power outage water supply operation unit and the drainage operation using the power outage drainage operation unit, which are different from normal operations.This allows users to properly perform power outage operations using both the power outage water supply operation unit and the power outage drainage operation unit, and simplifies complicated power outage operations.

[0008] In the present invention, the power outage drain operation unit is preferably detachably attached to the power outage water supply operation unit in a non-operating state. In the present invention configured in this manner, the power outage drainage operation unit in an inoperative state is detachably attached to the power outage water supply operation unit. Therefore, when starting a power outage operation, the user needs to remove the power outage drainage operation unit from the power outage water supply operation unit, making it easier to operate the power outage water supply operation unit, which does not require removal, as a priority.

[0009] In the present invention, the power outage water supply operating unit and the power outage water drain operating unit are preferably arranged so that the directions in which the operating shafts of the respective operating units are operated are the same. In the present invention configured in this manner, the water supply operation unit during power outages and the drainage operation unit during power outages are arranged so that the operating axes of each unit are operated in the same direction, so that the two operation units can be operated in the same operating axis direction during power outage operations. Therefore, it becomes easier for the user to understand how to operate the power outage water supply operation unit and the power outage drainage operation unit, and the operability of each operation unit can also be improved.

[0010] In the present invention, the power outage water supply operating section is preferably arranged in a substantially vertical position when in a non-operating state. In the present invention configured in this manner, the power outage water supply operation unit in a non-operating state is positioned in a nearly vertical position, making it easier for the user to understand and access the power outage water supply operation unit than the power outage drain operation unit, and therefore making it easier to perform water supply stop operations using the power outage water supply operation unit than drainage operations using the power outage drain operation unit.

[0011] In the present invention, preferably, the power outage drainage operation unit is provided with an annular operating member, and the power outage water supply operation unit is attached in a state where it is inserted into the annular operating member when in a non-operating state. In the present invention configured in this manner, the power outage drainage operation unit is equipped with a ring-shaped operating member, and the power outage water supply operation unit in a non-operating state is attached in a state inserted into the ring-shaped operating member of the power outage water supply operation unit.Therefore, when starting the power outage drainage operation, the user must first remove the ring-shaped operating member of the power outage water supply operation unit from the power outage water supply operation unit. Therefore, during a power outage, the user can be guided to prioritize the water supply operation using the power outage water supply operating unit over the drainage operation using the power outage drainage operating unit.

[0012] In the present invention, preferably, the functional portion further includes a support member that is inserted into the annular operating member in a non-operated state to support the annular operating member, The support member and the power outage water supply operating unit are attached in a state where they are inserted into the annular operating member in a non-operated state. In the present invention configured in this manner, the support member of the functional part can be inserted into and attached to the annular operating member of the power outage drainage operating part when it is in a non-operating state, so that the support member of the functional part can support the annular operating member of the power outage drainage operating part when it is in a non-operating state. In addition, with regard to the water supply operation unit during power outages in a non-operated state, the non-operated water supply operation unit during power outages can be attached to both the annular operation member of the power outage drainage operation unit in a non-operated state, which is supported by the support member of the functional unit, by inserting it into the annular operation member of the power outage drainage operation unit in a non-operated state, which is supported by the support member of the functional unit. Therefore, the two operating sections, the power outage water supply operating section and the power outage water drain operating section, which are in the non-operating state, can be stably attached to the support member of the functional section. [Effects of the Invention]

[0013] According to the flush toilet of the present invention, water supply and drainage operations can be easily and appropriately performed during a power outage. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0015] A flush toilet according to one embodiment of the present invention will now be described with reference to the accompanying drawings. First, the overall structure of a flush toilet according to one embodiment of the present invention will be explained in outline using FIGS. 1 to 3. FIG. Figure 1 is a diagram of the overall configuration of a flush toilet according to one embodiment of the present invention. Figure 2 is a plan view of a flush toilet according to one embodiment of the present invention. Figure 3 is an exploded perspective view of a flush toilet according to one embodiment of the present invention, seen from behind and diagonally above. Figure 4 is a rear view of a flush toilet according to one embodiment of the present invention. First, as shown in Figures 1 to 4, a flush toilet 1 according to one embodiment of the present invention comprises a water supply channel (main water supply channel 2) through which flush water supplied from a main water supply source W0 such as a water line flows, a ceramic toilet body 4, and a flush water supply device 6.

[0016] Next, as shown in Figures 1 to 3, the toilet body 4 comprises a bowl portion 8 for receiving waste, a rim portion 10 formed on the upper edge of the bowl portion 8, and a drain trap portion 12 extending from the bottom of the bowl portion 8. 1 to 4, the flush water supply device 6, which will be described in detail later, is provided behind the bowl portion 8 of the toilet body 4, and is a functional part that enables flush water supplied from the main water supply passage 2 to be supplied to the toilet body 4. More specifically, this functional part is powered by electricity, and includes the function of controlling the stop of flush water discharge into the bowl portion 8 of the toilet body 4.

[0017] Next, as shown in FIG. 2, a rim water channel 14 is formed inside the rim portion 10 on one of the left and right sides of the toilet body 4 (the right side when looking at the toilet body 4 from the front side). This rim water conduit 14 extends from the rear side of the toilet body 4 towards the front inside the rim section 10 on one of the left and right sides of the toilet body 4 (the right side when looking at the toilet body 4 from the front), and then bends towards the rear halfway, forming a so-called U-turn shape. Furthermore, a rim spout 14a is provided at the downstream end (rear downstream end) of this rim water conduit 14. Furthermore, the rim-side water supply passage 2a of the flush water supply device 6, which will be described in detail later, is connected to the upstream side of the rim water conduit 14 of the toilet body 4. Flush water supplied from this rim-side water supply passage 2a to the rim water outlet 14a is discharged rearward from the rim water outlet 14a into the bowl section 8, thereby performing rim spouting.

[0018] 1 and 2, a jet water conduit 16 is formed from the outer surface to the bottom of the bowl portion 8 of the toilet body 4. The downstream side of this jet water conduit 16 is directed toward the inlet 12a of the drain trap portion 12 at the bottom of the bowl portion 8, and a jet water outlet 16a is provided at the downstream end of the jet water conduit 16. Additionally, upstream of the jet water conduit 16 of the toilet body 4, there is provided a jet-side water supply conduit 2b of the flush water supply device 6, which will be described in detail later. Flush water supplied from this jet-side water supply conduit 2b to the jet water conduit 16 of the toilet body 4 is discharged from the jet water outlet 16a towards the inlet 12a of the drain trap section 12, thereby causing jet water to be discharged. Here, as shown in FIG. 1, the upstream side of the rim-side water supply passage 2a of the flush water supply device 6 is connected to a switching valve 18 at branch point B of the main water supply passage 2. On the other hand, as shown in Figure 1, the upstream side of the jet side water supply passage 2b of the flush water supply device 6 is connected to the pressure pump 22 of the flush water supply device 6, which is provided downstream of the water storage tank 20 of the flush water supply device 6.

[0019] Next, the drain trap section 12 of the toilet body 4 consists of an inlet section 12a provided at the bottom of the bowl section 8, an ascending pipe 12b rising from this inlet section 12a, and a descending pipe 12c descending from this ascending pipe 12b, with the top section 12d being between the ascending pipe 12b and the descending pipe 12c. As shown in FIG. 1, the outlet 12e of the downcomer pipe 12c of the drain trap portion 12 is connected to the inlet of a drain socket S located at the rear and below of the toilet body 4. Furthermore, as shown in Figure 1, the outlet on the rear side of the drain socket S is connected to the inlet of a drain pipe D extending from the rear wall (not shown) of the toilet body 4. As a result, the wastewater discharged from the outlet 12e of the drain trap part 12 of the toilet body 4 is discharged from the drain socket S into the drain pipe below the installation surface (floor surface F) of the bottom of the toilet body 4, which is a so-called "floor-side drainage" drainage form. Furthermore, the flush toilet 1 of this embodiment is not limited to this type of "floor-side drainage" drainage configuration, but can also be applied to a so-called "wall-side drainage" drainage configuration in which wastewater discharged from the outlet portion 12e of the drain trap portion 12 of the toilet body 4 is discharged from the drain socket S into the wall-side drain pipe D.

[0020] Next, each component of the flush water supply device 6 of the flush toilet 1 according to this embodiment will be explained in outline using FIG. First, as shown in FIG. 1, the flush water supply device 6 comprises, from the upstream side to the downstream side of the main water supply passage 2, a stop valve 24, a branch fitting 26, a valve unit 28, and a switching valve 18. Next, the valve unit 28 is a water supply unit that includes a constant flow valve 30, a diaphragm-type on-off valve (main valve 32), and an electromagnetic valve 34 such as a solenoid valve. The flush water supply device 6 also includes a controller 36. This controller 36 is capable of functioning as a control unit that controls the opening and closing operation of the solenoid valve 34 of the valve unit 28, the switching operation of the switching valve 18, and the rotation speed and operating time of the pressure pump 22.

[0021] Furthermore, the constant flow valve 30 of the valve unit 28 is used to restrict the flush water that has passed from the stop valve 24 in the main water supply passage 2 through the branch fitting 26 to a predetermined flow rate or less. Incidentally, in the case where a genital sanitary washing device (not shown) is provided for the flush toilet 1, the branch fitting 26 can also be connected to a water supply pipe (not shown) for supplying washing water to the genital sanitary washing device (not shown). Furthermore, in the valve unit 28, when the solenoid valve 34 is opened under the control of the controller 36, the main valve 32 opens, and the flushing water that has passed through the main valve 32 from the constant flow valve 30 is supplied to the switching valve 18 at the branch point B downstream of the main water supply line 2. Here, the switching valve 18 is capable of supplying flushing water from the main water supply passage 2 to both the rim side water supply passage 2a and the tank side water supply passage 2c at the same time, and the ratio of the amount of water supplied to the rim side and the tank side can be changed as desired.

[0022] Next, the flush water supply device 6 is equipped with a tank device T that enables flush water supplied from the main water supply passage 2 to be supplied to the toilet body 4. This tank device T is equipped with a water storage tank 20 that is connected to the rear of the toilet body 4 and stores the flush water supplied from the main water supply passage 2, and a pump (pressurizing pump 22) that pressure-feeds the flush water in this water storage tank 20 to the toilet body 4. Furthermore, downstream of the branch point B on the downstream side of the main water supply channel 2, there are provided a rim side water supply channel 2a that communicates with the rim water conduit 14 of the toilet body 4, and a tank side water supply channel 2c that is connected to the water storage tank 20. As a result, the flush water supplied from the main water supply source W0 to the branch point B of the main water supply passage 2 is used as at least one of the rim water supply to the rim side water supply passage 2a and the tank water supply to the tank side water supply passage 2c.

[0023] Furthermore, the flush water supply device 6 is provided with a pump water supply passage 2d that extends from the downstream side of the tank side water supply passage 2c to the pressure pump 22, and a jet side water supply passage 2b that extends downstream from the pressure pump 22. As a result, in the flush toilet 1 of this embodiment, flush water supplied from the main water supply channel 2 under direct water supply pressure is supplied from the rim-side water supply channel 2a of the flush water supply device 6 through the rim water conduit 14 of the toilet body 4 to the rim water outlet 14a, making it possible for water to be discharged from the rim water outlet 14a (so-called "rim water discharge"). Furthermore, the flush water supplied from the main water supply passage 2 to the flush water supply device 6 passes through the tank side water supply passage 2c, the water storage tank 20, the pump water supply passage 2d and the pressure pump 22 of the flush water supply device 6, and then from the jet side water supply passage 2b through the jet water conduit 16 of the toilet body 4 to the jet water outlet 16a, making it possible for water to be discharged from the jet water outlet 16a (so-called ``jet water discharge''). In other words, the flush toilet 1 of this embodiment is capable of using both rim spouting of flush water directly pressurized from the main water supply line 2 and jet spouting of flush water pressurized by the pressure pump 22 from the water storage tank 20, making it a so-called hybrid flush toilet 1.

[0024] Next, an upper float switch 38 and a lower float switch 40 are respectively disposed inside the water storage tank 20. The water level inside the water storage tank 20 can be detected by these float switches 38, 40. For example, the upper float switch 38 switches on when the water level in the water tank 20 reaches a predetermined water level, and the controller 36 detects that the upper float switch 38 is on and closes the solenoid valve 34. On the other hand, the lower float switch 40 switches on when the water level in the water storage tank 20 drops to a predetermined water level that is lower than the predetermined water level detected by the upper float switch 38, and the controller 36 detects the on state of the lower float switch 40 and stops the pressure pump 22. In addition, the pressure pump 22 draws flush water stored in the water storage tank 20 into the pump water supply passage 2d, and pressurizes the flush water from this pump water supply passage 2d into the jet side water supply passage 2b, thereby discharging it from the jet water outlet 16a.

[0025] With this structure, during normal toilet flushing, the controller 36 detects the user's operation of the toilet flush switch (not shown), and activates the solenoid valve 34, the switching valve 18, and the pressure pump 22 in sequence. This causes water to start being discharged sequentially from the rim water outlet 14a and the jet water outlet 16a, and the cleaning water that has cleaned the inside of the bowl section 8 is discharged from the drain trap section 12 together with the dirt in the bowl section 8. Furthermore, after flushing is completed, the controller 36 opens the electromagnetic valve 34, the switching valve 18 is switched to the tank-side water supply passage 2c side, and flush water in the main water supply passage 2 is replenished to the water storage tank 20. When the water level in the water storage tank 20 rises and the upper float switch 38 detects the specified amount of water stored, the controller 36 closes the solenoid valve 34, causing the main valve 32 to close the main water supply line 2 and stopping the water supply. Furthermore, each of these devices of the flush water supply device 6 (functional section) is stored in a rear functional storage section V0 in the area behind the bowl section 8 of the toilet body 4.

[0026] Furthermore, the flush water supply device 6 is equipped with a power outage operation device U that enables water supply and drainage operations in the event of a power outage. This power outage operation device U is equipped with a power outage water supply operation unit (power outage water supply operation device U1) that allows the water supply to the toilet body 4 to be stopped by manual operation, and a power outage drainage operation unit (power outage drainage operation device U2) that allows the internal flow path S1 of the drain socket S to be opened and closed by manual operation. The specific structures of these operating devices U1 and U2 during a power outage will be described later.

[0027] Next, as shown in FIGS. 2 to 4, the toilet body 4 is provided with a skirt portion 42 formed outside the respective side surfaces of the bowl portion 8 and the drain trap portion 12. In addition, the rear functional storage section V0 of the toilet body 4 is located below the upper ends of the rear wall section 42a and side wall section 42b of the skirt section 42 in the area rearward of the bowl section 8 of the toilet body 4, and inside the rear wall section 42a and side wall section 42b of the skirt section 42. As a result, the rear functional storage section V0 of the toilet body 4 forms a storage area that can store at least a portion of the flush water supply device 6 (functional section).

[0028] Next, as shown in FIGS. 3 and 4, the flush toilet 1 of this embodiment is equipped with a tank mounting member 44 that secures the storage tank 20 of the flush water supply device 6 to the toilet body 4. When the flush water supply device 6 is stored in the rear function storage section V0 of the toilet body 4, first, only the tank mounting member 44 alone is fixedly attached to the rear function storage section V0 of the toilet body 4. When the water storage tank 20 of the flushing water supply device 6 is attached to the tank mounting member 44, the flushing water supply device 6 is held by the tank mounting member 44 and is also fixed to the rear function storage section V0 of the toilet body 4 via this tank mounting member 44. Furthermore, the tank mounting member 44 covers the back and bottom sides of the flush water supply device 6, and also functions as a back cover member that closes the opening cross section 46a of the upper opening 46 on the back side (rear wall portion 42a) of the toilet body 4. As a result, when the flush water supply device 6 is attached to the tank mounting member 44, the back and bottom sides of the flush water supply device 6 are covered by the tank mounting member 44.

[0029] Next, with reference to Figures 1 and 3 to 9C, we will explain the specific structure of the power outage operation device U (power outage water supply operation device U1, power outage water drainage operation device U2) in the cleaning water supply device 6 (functional part) and their surrounding parts. First, Fig. 5 is a partially enlarged perspective view of the rear part of a flush toilet according to one embodiment of the present invention, viewed from diagonally above. Next, Fig. 6 is a perspective view showing the upper structure of a flush water supply device for a flush toilet according to one embodiment of the present invention. Also, Fig. 7 is a partially enlarged perspective view of the power outage operating device part in the upper structure of a flush water supply device for a flush toilet according to one embodiment of the present invention, viewed from diagonally above. Furthermore, Fig. 8 is a cross-sectional view taken along line VIII-VIII in Fig. 6. First, as shown in FIG. 1 and FIGS. 5 to 8, the flush water supply device 6 is equipped with a thin plate-shaped base member 48 fixed to the upper outside of the water storage tank 20. Also, on the base member 48, an operating section (controller 36, etc.) including an electrical component such as electric parts is arranged. Furthermore, an operating part storage chamber 54 is provided on the base member 48, which allows the respective operating parts (valve operating ring 50, flapper operating ring 52) of the power outage water supply operating device U1 and the power outage water drainage operating device U2 to be placed therein.

[0030] 5 to 8, the operation part storage chamber 54 has a peripheral wall 54a extending upward from a bottom surface 54c formed so as to surround the side of the operation part storage chamber 54. The peripheral wall 54a is provided to separate the operation parts (valve operation ring 50, flapper operation ring 52) from the actuation part (controller 36, etc.). In addition, an upper opening 54b that is open at the top and rear is provided in the peripheral wall 54a of the operation unit storage chamber 54. Since this upper opening is open at the top and rear, it becomes easier to operate the power outage operation device U. Furthermore, the flush water supply device 6 is provided with an upper cover member 56 that covers at least the top of the upper opening 54b. This upper cover member 56 is provided so as to be removable from at least the upper opening 54b. For example, during a power outage, by removing the upper cover member 56, the upper and rear sides of the operation unit storage chamber 54 are opened, allowing the user to access the operation units (valve operation ring 50, flapper operation ring 52) of the power outage water supply operation device U1 and the power outage drainage operation device U2.

[0031] Inner cover members 58 are provided inside the upper cover member 56 and on both the left and right sides of the operation unit storage chamber 54. These inner cover members 58 cover the upper parts of the spaces partitioned on both the left and right sides of the operation unit storage chamber 54. That is, for example, when attempting to perform a power outage operation using the power outage operation device U, even if the upper cover member 56 is removed, only the upper opening 54b of the operation unit storage chamber 54 remains open, and the areas other than the upper opening 54b are covered by the inner cover member 58.

[0032] Furthermore, even if the operation unit storage chamber 54 is flooded with water while the upper opening 54b is open, the water inside the operation unit storage chamber 54 is blocked by the peripheral wall portion 54a, preventing water from leaking into the operating parts (controller 36, etc.) located outside the operation unit storage chamber 54. That is, the inner area of ​​the operation unit storage chamber 54 formed by the peripheral wall 54a is the waterproof area A1. This waterproof area A1 is separated from the outer area A2 where the operating unit (controller 36, etc.) is arranged by the peripheral wall 54a, and the two are isolated from each other.

[0033] Next, as shown in FIGS. 5 to 8, the power outage water supply operating device U1 includes a fixed tube 60, a wire 62 for operating water supply during a power outage (hereinafter referred to as the "water supply operating wire 62"), and a valve operating ring 50. First, one end 60a of the fixed tube 60 is fixed to a part of the valve unit 28. Meanwhile, the other end 60b of the fixed tube 60 is attached to a part of the peripheral wall 54a of the operation part storage chamber 54 of the base member 48, and is held (fixed) from above by a holding member 48a fixed to a part of the base member 48. Next, the water supply operation wire 62 is a flexible metal wire that is provided so that it can be inserted into the fixed tube 60. One end of this water supply operation wire 62 (the end on the valve unit 28 side) is connected to part of the opening / closing mechanism (not shown) of the valve unit 28 that enables the diaphragm-type main valve 32 to be opened and closed, and the other end of the water supply operation wire 62 is connected to the valve operation ring 50.

[0034] 6 to 8, support columns 54d, 54e (central support column 54d, lower support column 54e) extending upward from the bottom surface 54c are provided within the operation section storage chamber 54 of the base member 48 of the flush water supply device 6. These support columns 54d, 54e function as support members that support the valve operation ring 50 and flapper operation ring 52, which are annular operation members. Specifically, in the non-operating state, when the upper portion of the central support column 54d of the flapper operating ring 52 of the power outage drain operating device U2 is inserted into the operating unit storage chamber 54 and the lower surface of the flapper operating ring 52 in a horizontal position is seated against the upper surface of the lower support column 54e, the inner peripheral surface of the flapper operating ring 52 is supported from the inside by the central support column 54d, and the lower surface of the flapper operating ring 52 is supported from below by the upper end of the lower support column 54e. As a result, the flapper operating ring 52 in the non-operating state is detachably attached to the support columns 54d, 54e.

[0035] Furthermore, the central support portion 54d extends higher than the lower support portion 54e, but it is more preferable that this central support portion 54d extend upward to a height approximately equal to the upper end of the valve operating ring 50. This makes it easier to maintain the upright position of the valve operating ring 50. Furthermore, the lower support portion 54e extends below the center of the left-right axis that divides the valve operating ring 50 into upper and lower halves in the up-down direction. As a result, even when the flapper operating ring 52 is attached so as to be detachable to the lower support portion 54e, it is positioned so as not to interfere with the operation of the valve operating ring 50, and is also positioned so that the presence of the flapper operating ring 52 is easily noticed when operating the valve operating ring 50.

[0036] On the other hand, as shown in FIG. 7, the valve operating ring 50 in the non-operating state (standby state) is detachably attached to the flapper operating ring 52 in the non-operating state (standby state). More specifically, the valve operating ring 50 of the water supply operating device U1 during a power outage is a flexible member that allows elastic deformation. This allows the valve operating ring 50 in an elastically deformed state to be inserted into the inner cavity of the flapper operating ring 52 in a non-operating state (standby state) that is attached to the support members 54d, 54e in the operating unit storage chamber 54. Therefore, when the central support portion 54d and the valve operating ring 50 are inserted into the inner cavity of the flapper operating ring 52 in a non-operating state (standby state), the flapper operating ring 52 is removably attached to the central support portion 54d and the valve operating ring 50.

[0037] Next, as shown in FIGS. 5 to 8, the drainage operation device U2 during a power outage includes a fixed tube 64, a drainage operation wire 66, a holder 68, a flapper device 70, and a flapper operation ring 52. First, as shown in Figure 1, the flapper device 70 has a flapper valve 70a that is openable and closable in the internal flow path S1 of the drain socket S, and serves as a socket opening and closing part that opens and closes the internal flow path S1 of the drain socket S. Here, the flapper valve 70a keeps the internal flow path S1 of the drain socket S open during normal use. One end of the fixed tube 64 is fixed to a part of the flapper device 70 , while the other end is fixed to the holder 68 .

[0038] Next, as shown in Figures 7 and 8, the holder 68 is a generally cylindrical member and includes a generally cylindrical main shaft portion 68a, a flange portion 68b provided in an annular shape on the outer periphery of this main shaft portion 68a, and a locking protrusion 68c protruding outward from this flange portion 68b. In addition, the main shaft portion 68a of the holder 68 is inserted into an opening 48b that penetrates the bottom surface 54c of the operating unit storage chamber 54 of the base member 48, and is held in a state in which the flange portion 68b is coaxially fitted into the opening 48b. Furthermore, the locking projection 68c of the holder 68 projects rearward from the rear end of the flange portion 68b and is held in contact with the lower end side of the opening 48b. As a result, as shown in FIG. 8, water (drained water w1) that has fallen into the operation unit storage chamber 54 is discharged from the opening 48b into the guide groove 72 on the back surface of the tank mounting member 44 below.

[0039] Next, the drain operation wire 66 is provided so that it can be inserted into the fixed tube 64. One end of this drain operation wire 66 (the end on the flapper device 70 side) is connected to part of an opening / closing mechanism (not shown) that enables the flapper device 70 to be opened and closed, and the other end of the drain operation wire 66 (the end on the flapper operation ring 52 side) is connected to the flapper operation ring 52 via a connecting loop 52a. During normal use, the flapper operation ring 52 of the drainage operation device U2 for use in case of a power outage is detachably attached to the support column 54d in the operation unit storage chamber 54. As a result, the flapper operation ring 52 of the drainage operation device U2 for use in case of a power outage, a portion of the drainage operation wire 66 on the flapper operation ring 52 side, and a portion of the upper side of the holder 68 are located within the waterproof area A1 of the operation unit storage chamber 54. As a result, when in a non-operating state (or standby state), the valve operating ring 50 and the flapper operating ring 52 are each located in the same location in the operating unit storage chamber 54 of the base member 48 of the flush water supply device 6.

[0040] Furthermore, as shown in Figure 7, in particular, the valve operating ring 50 of the power outage water supply operating device U1 in the non-operated state stands upright in the direction of the operating axis Z1 (vertical direction) of its water supply operating wire 62, and is positioned in an almost vertical position. On the other hand, as shown in Figures 7 and 8, the flapper operating ring 52 of the drainage operation device U2 during a power outage when in an unoperated state is arranged in a horizontal position so as to be positioned in a different operating axis direction that is perpendicular (horizontal) to the operating axis Z2 direction (vertical direction) of the operating wire 66 for drainage operation during a power outage (hereinafter referred to as the "drainage operation wire 66") that is inserted through the fixed tube 64. Incidentally, as shown in Figures 7 and 8, the operating axis Z1 of the water supply operating wire 62 and the operating axis Z2 of the drainage operating wire 66 each extend in the vertical direction, and the two operating axes Z1, Z2 are arranged parallel to each other so that they are in the same direction (vertical direction). Also, as shown in Figure 7, the valve operating ring 50 in an upright position in the non-operating state (standby state) is positioned so that its upper end 50a is positioned higher than the upper surface 52b of the flapper operating ring 52 in a horizontal position in the non-operating state (standby state). Furthermore, the valve operating ring 50 in an upright position in the non-operating state (standby state) is positioned so that its upper end 50a is positioned higher than the upper surface 52b of the flapper operating ring 52 in a horizontal position in the non-operating state (standby state).

[0041] Next, an example of manual operation of the power failure water supply operating device U1 and the power failure drain operating device U2 during a power failure will be described with reference to Figs. 1 and 5 to 9C. Figure 9A is a view taken along line IXA-IXA in Figure 7, showing the valve operating ring of a water supply operating device for a flush toilet during a power outage according to one embodiment of the present invention in a non-operated state (standby state). Also, Figure 9B is a view similar to Figure 9A, showing the state after a power outage operation in which the valve operating ring of a water supply operating device for a flush toilet during a power outage according to one embodiment of the present invention has been pulled up from the standby state. Furthermore, Figure 9C is a view similar to Figures 9A and 9B, showing the state after a power outage operation in which the valve operating ring of a water supply operating device for a flush toilet during a power outage according to one embodiment of the present invention has been pulled back from the pulled up state.

[0042] First, before starting the power outage operation, the upper cover member 56 shown in FIG. 5 is removed to open the upper opening 54b of the operation unit storage chamber 54. 9A, the holding member 48a of the base member 48 is provided with a wire guide portion 48c. This wire guide portion 48c is positioned above the water supply operation wire 62 so as to face the water supply operation wire 62 of the water supply operation device U1 in the event of a power outage, and the surface facing the water supply operation wire 62 forms a curved surface R. Also, as shown in Figure 9A, in the non-operating state (standby state), in order to maintain the upright position of the valve operating ring 50, the portion of the water supply operating wire 62 between the valve operating ring 50 and the end 60b of the fixed tube 60 is elastically bent in a concave curve upward. As shown in FIG. 9A, in the non-operating state (standby state), the curved surface R of the wire guide portion 48c and the water supply operation wire 62 are not in contact with each other.

[0043] Next, as shown in FIG. 9B, to start the power outage operation, the valve operating ring 50 is manually pulled upward. At this time, a part of the water supply operation wire 62 during operation comes into contact with the curved surface R of the wire guide portion 48c. However, in the elevation view of FIG. 9B, the radius of curvature r1 of the curved surface R of the wire guide portion 48c is smaller than the average radius of curvature r2 of the water supply operation wire 62 in a state of being elastically bent in a concave curved shape (r1 < r2). Thus, even if the water supply operation wire 62 comes into contact with the curved surface R of the wire guide portion 48c when it slides, the sliding resistance (frictional resistance) due to contact with the curved surface R of the wire guide portion 48c can be suppressed.

[0044] Then, as shown in FIG. 9B, after pulling up the water supply operation wire 62 by a predetermined length by manually pulling the valve operation ring 50, as shown in FIG. 9C, by returning the water supply operation wire 62 to its original position again, the main valve 32 is opened through an opening / closing mechanism (not shown) of the valve unit 28, and the water supply operation by the valve unit 28 is manually executed. Thereby, the water discharge (rim water discharge) from the main water supply passage 2 through the rim side water supply passage 2a to the inside of the bowl portion 8 from the rim water discharge port 14a of the toilet body 4 is started. At this time, as shown in FIG. 9C, when the water supply operation wire 62 returns to its original position (standby position), although there is some slack compared to the water supply operation wire 62 during pulling up, since the radius of curvature r1 of the curved surface R of the wire guide portion 48c is smaller than the average radius of curvature r2 of the water supply operation wire 62 in a state of being elastically bent in a concave curved shape (r1 < r2), the water supply operation wire 62 can return to the original position (standby position) shown in FIG. 9A without contacting the curved surface R of the wire guide portion 48c.

[0045] Next, the flapper operation ring 52 of the drainage operation device U2 during a power outage is removed from the support member 54d and the valve operation ring 50, and while pulling up the drainage operation wire 66 by a predetermined length by manually pulling the flapper operation ring 52, the flapper valve 70a is closed through an opening / closing mechanism (not shown). This causes water to start accumulating in the bowl portion 8 of the toilet body 4, and water sealing also begins in the internal flow path S1 of the drain socket S upstream of the flapper valve 70a and in the drain trap portion 12 of the toilet body 4.

[0046] Next, when the water level in the bowl portion 8 of the toilet body 4 rises to a predetermined level that will not overflow but will allow the toilet to be flushed, i.e., a level that will cause a siphon action in the drain trap portion 12, the flapper operation ring 52 of the power outage drain operation device U2 is released (stop pulling and return the drain operation wire 66 to its original position), and the flapper valve 70a opens via the opening and closing mechanism (not shown). This opens the internal flow path S1 within the drain socket S, causing a siphon action within the drain trap section 12 of the toilet body 4, and the flushing water within the bowl section 8 is drained from the drain trap section 12 through the drain socket S into the drain pipe D. Then, as shown in FIG. 9B, the water supply operation wire 62 is pulled up by a predetermined length by manually pulling the valve operation ring 50, and then the water supply operation wire 62 is returned to its original position as shown in FIG. 9C. This causes the main valve 32 to close via the opening / closing mechanism (not shown) of the valve unit 28, and the water stopping operation is manually performed by the valve unit 28, stopping the discharge of water (rim discharge) from the main water supply passage 2 through the rim side water supply passage 2a to the rim water outlet 14a of the toilet body 4 into the bowl section 8. As a result, a series of water supply and drainage operations related to toilet flushing during a power outage are completed.

[0047] Next, the operation of the flush toilet 1 according to one embodiment of the present invention described above will be explained with reference to Figures 1 to 9C. First, in a flush toilet 1 according to one embodiment of the present invention, the valve operating ring 50 and flapper operating ring 52 in the non-operating state (or standby state) are each provided in the same location in the operating part storage chamber 54 of the base member 48 of the flush water supply device 6. This makes it easier for the user to grasp the positions of the two operating parts, the valve operating ring 50 and the flapper operating ring 52, even when performing power outage operations that differ from normal operations, thereby reducing the effort required to start power outage operations. In addition, the valve operating ring 50 in the non-operated state is positioned in the direction of the operating axis Z1 (vertical direction) of its water supply operating wire 62, while the flapper operating ring 52 in the non-operated state is positioned offset in the direction of the operating axis Z2 of its drainage operating wire 66. As a result, the two valve operating rings 50 and the flapper operating ring 52 provided at the same location on the flush water supply device 6 can be arranged in mutually different operating axis directions relative to their respective operating axis Z1, Z2 directions. Therefore, the user can easily grasp the respective positions of the two operating units 50, 52, which have different functions, and can prevent erroneous operations. Furthermore, by positioning the valve operating ring 50, which has a higher priority for power outage operations than the flapper operating ring 52, in the direction of the operating axis Z1, it becomes easier for the user to perform water supply and stop operations using the valve operating ring 50 than to perform drainage operations using the flapper operating ring 52. Furthermore, during a power outage, the user can be guided to give priority to the water supply operation using the valve operation ring 50 over the water drain operation using the flapper operation ring 52. As a result, the user can easily understand the two different operation procedures during a power outage, namely the water supply operation using the valve operation ring 50 and the drainage operation using the flapper operation ring 52, which are different from normal operations. This allows the user to properly perform power outage operations using each of the valve operation ring 50 and the flapper operation ring 52, and also simplifies complicated power outage operations.

[0048] Furthermore, with the flush toilet 1 according to this embodiment, the valve operating ring 50 in the unoperated state is positioned higher than the flapper operating ring 52 in the unoperated state. This allows the two valve operating rings 50 and the flapper operating ring 52, which are provided in the same location in the operating unit storage chamber 54 of the base member 48 of the cleaning water supply device 6, to be positioned at different heights. This makes it easier for the user to understand the respective positions of the two operating units 50, 52, which have different functions, and can prevent erroneous operations. Furthermore, by placing the valve operation ring 50, which has a higher priority for power outage operations, above the flapper operation ring 52, it becomes easier for users to access the valve operation ring 50 than the flapper operation ring 52, making it easier to perform water supply and stop operations using the valve operation ring 50 than to perform water drainage operations using the flapper operation ring 52. Furthermore, during a power outage, the user can be guided to give priority to the water supply operation using the valve operation ring 50 over the water drain operation using the flapper operation ring 52. As a result, the user can easily understand the two different operation procedures during a power outage, namely the water supply operation using the valve operation ring 50 and the drainage operation using the flapper operation ring 52, which are different from normal operations. This allows the user to properly perform power outage operations using each of the valve operation ring 50 and the flapper operation ring 52, and also simplifies complicated power outage operations.

[0049] Furthermore, with the flush toilet 1 according to this embodiment, the flapper operation ring 52 in the unoperated state is detachably attached to the valve operation ring 50. This allows the user to easily operate the valve operating ring 50, which does not require removal, preferentially, since the user needs to remove the flapper operating ring 52 from the valve operating ring 50 when starting a power outage operation.

[0050] Furthermore, according to the flush toilet 1 of this embodiment, the operating axis Z1 of the water supply operating wire 62 and the operating axis Z2 of the drain operating wire 66 each extend vertically, and the two operating axes Z1, Z2 are arranged parallel to each other so that the directions in which the operating axes Z1, Z2 are operated are the same (vertical). This allows the two operating units 50, 52 to be operated in the same direction (vertical direction) along the operating axes Z1, Z2 during power outage operation. Therefore, it becomes easier for the user to understand how to operate the valve operating ring 50 and the flapper operating ring 52, and the operability of each operating section 50, 52 can also be improved.

[0051] Furthermore, with the flush toilet 1 according to this embodiment, the valve operating ring 50 is positioned so that it is nearly vertical when not in operation. This makes it easier for the user to grasp and access the valve operation ring 50 than the flapper operation ring 52, making it easier to perform water supply and stop operations using the valve operation ring 50 than to perform drainage operations using the flapper operation ring 52.

[0052] Furthermore, with the flush toilet 1 according to this embodiment, the flapper operation ring 52 is an annular operating member, and the valve operation ring 50 in the non-operating state is attached in a state where it is inserted into the flapper operation ring 52. As a result, when the user starts the power outage operation, he or she must first remove the valve operating ring 50 inserted into the flapper operating ring 52 in the non-operated state. Therefore, during a power outage, the user can be guided to give priority to the water supply operation using the valve operation ring 50 over the water drain operation using the flapper operation ring 52.

[0053] Furthermore, with the flush toilet 1 of this embodiment, by inserting and attaching the support member (central support portion 54d) of the base member 48 of the flush water supply device 6 into the annular flapper operation ring 52 in the non-operated state, the support members (central support portion 54d, lower support portion 54e) of the base member 48 of the flush water supply device 6 can support the annular flapper operation ring 52 in the non-operated state. Furthermore, by inserting the valve operating ring 50 in the non-operated state into the annular valve operating ring 50 in the non-operated state that is supported by the support members (central support portion 54d, lower support portion 54e) of the base member 48 of the cleaning water supply device 6, the valve operating ring 50 in the non-operated state can be attached to each of the annular flapper operating ring 52 and the support members (central support portion 54d, lower support portion 54e) of the base member 48 of the cleaning water supply device 6. Therefore, the two operating parts, the valve operating ring 50 and the flapper operating ring 52 in the non-operated state, can be stably attached to the support members (central support part 54d, lower support part 54e) of the base member 48 of the flush water supply device 6.

[0054] In the flush toilet 1 according to one embodiment of the present invention described above, examples of operating parts that are placed within the waterproof area A1 of the base member 48 of the flush water supply device 6 are described as operating parts for responding to power outages, employing the valve operating ring 50 of the power outage water supply operating device U1 and the flapper operating ring 52 of the power outage drain operating device U2, but this is not limited to such forms, and the invention can also be applied to other forms that employ operating parts other than operating parts for responding to power outages, or operating parts that perform operations other than those of functional parts (flush water supply device 6). For example, as an operating unit of another type that employs an operating unit other than an operating unit for responding to power outages, an operating unit for performing operations related to a local cleaning device (not shown) other than the functional unit (cleaning water supply device 6) may be applied. Alternatively, as another type of operating unit that employs an operating unit that performs operations other than the functional unit (flushing water supply device 6), an operating unit for operating such a heater device (not shown) in a flush toilet that is equipped with a heater device or the like for cold climate specifications may be applied. Furthermore, as a variation of the flush toilet 1 according to one embodiment of the present invention described above, the valve operating ring 50 and flapper operating ring 52 may be positioned in the same axial direction, with the valve operating ring 50 positioned higher than the flapper operating ring 52. Furthermore, as yet another variation of the flush toilet 1 according to one embodiment of the present invention described above, the flapper operating ring 52 may be detachably attached only to the support member 54d or 54e. Furthermore, in the flush toilet 1 according to one embodiment of the present invention described above, a configuration has been described in which the valve operating ring 50 is arranged to be operated with priority during power outage operation, but the flapper operating ring 52 may also be arranged to be operated with priority in accordance with the power outage operation mechanism, or the arrangement of the flapper operating ring 52 and valve operating ring 50 may be changed as desired to suit the specifications of the power outage operation mechanism.
