[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-38635 [Patent Document 2] Patent No. 5447706 Summary of the Invention [Problem to be solved by the invention]

[0004] 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 during emergencies such as disasters. Furthermore, with the conventional flush toilets mentioned above, when lighting and other functions cannot be used during a power outage, the user must manually perform flushing operations that differ from normal operations by feel, but it is difficult to grasp the location and operation procedures of the various operating parts for manually performing water supply and drainage operations during a power outage (hereinafter referred to as "manual operating parts during a power outage"), making it difficult to perform appropriate power outage operations. Therefore, when performing water supply and drainage operations during a power outage, the challenge is how users can quickly understand the location and operation procedures of each control part for water supply and drainage operations, and how to simplify the complicated power outage operations and perform them appropriately. In short, in order to solve the problems and issues of the conventional technology described above, how to improve the visibility and operability of the manual operation unit during a power outage has become a challenge that has been required in recent years.

[0005] Therefore, the present invention has been made to solve the problems and desired issues of the prior art mentioned above, and aims to provide a flush toilet that can improve the visibility and operability of the manual operation part 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; 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 that is provided downstream of the drain trap portion of the toilet body; The toilet has a socket opening / closing section that opens and closes the flow path, a power outage manual operation section for manually performing a flushing operation on the toilet body during a power outage, and a cover member that is removable so as to cover the side of the power outage manual operation section, and the power outage manual operation section has a manually operated handle section and a storage section that is provided on the side of the toilet body and stores the handle section so that it can be removed, and the handle section is stored in the storage section covered by the cover member during standby, and is configured to jump out from within the storage section to the outside when the cover member is removed during a power outage operation. In the present invention configured in this manner, the grip portion of the power outage manual operation unit is stored in a storage section covered by a cover member during standby, but is configured to pop out from within the storage section to the outside when the cover member is removed during power outage operation.Therefore, when starting power outage operation, the user can easily grasp the grip portion that has popped out from within the storage section of the power outage manual operation unit by simply removing the cover member. Therefore, when performing a power outage operation, the grip portion of the power outage manual operation unit can be accessed quickly, allowing subsequent power outage operations to be carried out smoothly. As a result, the visibility and operability of the manual operation unit during a power outage can be improved.

[0007] In the present invention, preferably, the manual operation unit during a power outage includes a water supply operation unit during a power outage that manually opens and closes the on-off valve of the water supply unit during a power outage, thereby enabling water supply to the toilet body to be stopped, and a drainage operation unit during a power outage that manually opens and closes the socket opening and closing unit during a power outage, thereby enabling drainage from the drain socket unit and storage of water in the bowl unit, and the grip unit is part of the water supply operation unit during a power outage. In the present invention configured in this manner, the manual operation unit during power outages has two operation units: a power outage water supply operation unit that enables the water supply to the toilet body to be stopped, and a power outage drain operation unit that enables the drainage operation from the drain socket unit and the storage of water in the bowl unit.When starting power outage operations, the user can easily determine the position of the grip unit, which is part of the power outage water supply operation unit that protrudes from inside the storage unit to the outside, by simply removing the cover member. Therefore, a user who is about to start operating the manual operation unit during a power outage can be guided to the effect that the water supply stop operation using the water supply operation unit during a power outage should take priority over the drainage operation using the drainage operation unit during a power outage, allowing appropriate water supply and drainage operations to be performed when responding to a power outage.

[0008] In the present invention, preferably, the power outage water supply operation unit and the power outage drainage operation unit each have a first grip portion and a second grip portion that are manually operated, and the storage portion forms a common storage area for the power outage water supply operation unit and the power outage drainage operation unit inside the cover member, and when in standby mode, the first grip portion and the second grip portion are each stored in the common storage area. In the present invention configured in this manner, the storage section forms a common storage area for the power outage water supply operation section and the power outage drainage operation section inside the cover member, and the first grip section of the power outage water supply operation section and the second grip section of the power outage drainage operation section are each stored in the common storage area for the power outage water supply operation section and the power outage drainage operation section.Therefore, when starting a power outage operation, the user can easily access each of the first grip section and the second grip section in the common storage area by simply removing the cover member. Furthermore, since the first grip portion and the second grip portion are provided in a common storage area, they are easy to operate.

[0009] In the present invention, preferably, the common storage area is provided on the side of the toilet body, and the power outage water supply operation unit is positioned above the power outage drain operation unit within the common storage area. In the present invention configured in this manner, the power outage water supply operation unit is located higher than the power outage drain operation unit within a common storage area provided on the side of the toilet body, so that a user looking at the power outage manual operation unit from above during a power outage can more easily grasp (visualize) the power outage water supply operation unit than the power outage drain operation unit. Therefore, a user who is about to start operating the manual operation unit during a power outage can be guided to the effect that the water supply stop operation using the water supply operation unit during a power outage should take priority over the drainage operation using the drainage operation unit during a power outage, allowing appropriate water supply and drainage operations to be performed when responding to a power outage.

[0010] In the present invention, preferably, the power outage water supply operating section further includes a towing member having one end connected to the water supply unit and the other end connected to the first gripping section, which enables the opening and closing operation of the on-off valve, and a guide section which guides the first gripping section and the towing member in the operating direction when the cover member is removed. In the present invention configured in this manner, when the user starts the power outage operation, he or she can remove the cover member, and the first gripping portion and the towing member connected to it, which are protruding from the storage portion of the power outage water supply operation unit, can be guided in the operating direction by the guide portion of the power outage water supply operation unit. In addition, when the user pulls the towing member in the operating direction together with the first gripping portion of the power outage water supply operating unit, the guide portion of the power outage water supply operating unit can prevent deformation such as kinking of the towing member, allowing the gripping portion and towing member to be pulled smoothly. Therefore, the load on the first grip portion and the traction member of the water supply operating unit during a power outage can be reduced, thereby improving operability.

[0011] In the present invention, preferably, further, the towing member is a flexible metal wire member and can be operated by towing the first gripping portion at least in the up-down or front-to-back direction, and the guide portion has an opening provided above and to the side of the storage portion to allow the metal wire member to be inserted, and this opening has an upper opening edge portion whose upper edge is formed in a convex curve facing upward in a side view, and a front opening edge portion and a rear opening edge portion extending downward from the front and rear lower ends of the upper opening edge portion, respectively, and at least one of the upper opening edge portion, the front opening edge portion and the rear opening edge portion is chamfered so as to be able to come into contact with a part of the metal wire member when the power outage water supply operating portion is operated. In the present invention configured in this manner, the towing member is a flexible metal wire member, and when the user begins the power outage operation, the first gripping portion of the power outage water supply operation unit can be easily ejected from inside the storage portion to the outside by simply removing the cover member due to the elastic force of the flexible metal wire member. Thereafter, by pulling the first gripping portion of the water supply operating portion during a power outage at least up and down or forward and backward, the opening and closing valve of the water supply unit can be opened and closed, thereby enabling smooth water supply and stopping operations of the water supply unit during a power outage. In addition, the guide section of the water supply operating section during power outages is provided with an opening located above and to the side within the storage section, allowing the towing member (metal wire member) to be inserted, and at least one of the upper opening edge, front opening edge, and rear opening edge of this opening is chamfered so that it can come into contact with part of the towing member (metal wire member) during the towing operation of the water supply operating section during power outages.This reduces the frictional resistance at the contact part between the chamfered part and the towing member (metal wire member), making it easier to guide the first gripping section and the towing member in the operating direction during the towing operation. Furthermore, when the user pulls the towing member in the operating direction together with the first gripping portion of the power outage water supply operating unit, the guide portion of the power outage water supply operating unit can appropriately guide the movement of the towing member, thereby preventing deformation of the towing member such as kinking and allowing the gripping portion and towing member to be pulled smoothly. As a result, the load on the first grip portion and the traction member of the water supply operation unit during a power outage can be reduced, further improving operability.

[0012] In the present invention, preferably, in a standby state with the cover member attached, the storage section stores the first gripping portion in a state in which the metal wire member near the connection portion with the first gripping portion is elastically bent in advance, and when the cover member is removed, the elastic force of the metal wire member guides the first gripping portion in the storage section to jump out to the outside, and then, by pulling the first gripping portion in at least one direction, either upward or toward the front or rear, a part of the metal wire member can come into contact with any one of the chamfered portions of the upper opening edge, the front opening edge, or the rear opening edge in the guide section. In the present invention configured in this manner, in the storage section of the power outage water supply operating section in standby mode with the cover member attached, the first gripping portion is stored in a state where the metal wire member near the connection with the first gripping portion is elastically bent in advance, and when the cover member is removed during power outage operation, the elastic force of the metal wire member can guide the first gripping portion inside the storage section to pop out to the outside. Thereafter, when the first gripping portion of the power outage water supply operating portion is pulled in at least one direction, either upward or toward the front or rear, a part of the pulling member (metal wire member) comes into contact with one of the chamfered portions of the upper opening edge, the front opening edge, or the rear opening edge of the guide portion, thereby suppressing the frictional resistance at the contact portion between this chamfered portion and the pulling member (metal wire member). Therefore, the pulling operation of the first gripping portion and the pulling member (metallic wire member) can be carried out smoothly. As a result, the load on the first grip portion and the traction member of the water supply operation unit during a power outage can be reduced, further improving operability.

[0013] In the present invention, preferably, the metal wire member is partially covered by a fixing tube, and a fixing portion is provided at the tip of the fixing tube for fixing the metal wire member to the storage portion, and this fixing portion has an insertion hole that allows the metal wire member to be inserted, and the insertion hole is formed so that its inner diameter increases toward the outside in the axial direction, and the inner surface of the insertion hole is formed into a convex curved surface toward the center of the insertion hole. In the present invention configured in this manner, a fixing portion for fixing the metal wire member to the storage portion is provided at the tip of the fixing tube that partially covers the metal wire member, and the insertion hole in this fixing portion, which allows the metal wire member to be inserted, is formed so that its inner diameter increases toward the outside in the axial direction, and the inner surface of this insertion hole is formed into a convex curved surface toward the center of the insertion hole.Therefore, regardless of the direction from which the metal wire member is pulled, the frictional resistance at the contact point between the metal wire member and the inner surface of the insertion hole can be suppressed, and the first gripping portion and pulling member can be operated smoothly during the pulling operation. Furthermore, when the user pulls the towing member in the operating direction together with the first gripping portion of the power outage water supply operating unit, the convex curved inner surface of the insertion hole of the fixing part can appropriately guide the movement of the metal wire member when the gripping portion is pulled, thereby preventing deformation such as kinking of the metal wire member and allowing the gripping portion and metal wire member to be pulled smoothly. As a result, the load on the first grip portion and the metal wire member of the water supply operation unit during a power outage can be reduced, further improving operability.

[Figure 6] FIG. 1 is a perspective view of a flush operation unit for use in the event of a power outage in a flush toilet according to an embodiment of the present invention, seen from diagonally front left. DETAILED DESCRIPTION OF THE INVENTION

[0016] 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. Figure 1 is a diagram showing the overall configuration of a flush toilet according to one embodiment of the present invention, and Figure 2 is a left side view of the flush toilet according to one embodiment of the present invention. First, as shown in Figures 1 and 2, 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.

[0017] Next, as shown in Figures 1 and 2, 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 and 2, 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.

[0018] Next, as shown in FIG. 1, 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.

[0019] 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.

[0020] Next, as shown in Figure 1, 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 section 12 is connected to the inlet of a drain socket section (drain socket S) located behind and below 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.

[0021] 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 equipped with a constant flow valve 30, a diaphragm-type main valve 32, and an electromagnetic valve 34 such as a solenoid valve. In other words, the valve unit 28 is a water supply unit that enables the supply and stop of flush water supplied to the toilet body 4 by opening and closing the main valve 32 and the electromagnetic valve 34. The cleaning water supply device 6 also includes a controller 36. The controller 36 is capable of functioning as a control unit that controls the opening and closing operation of the on-off valve (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.

[0022] 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 private cleaning 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 cleaning water to the private cleaning 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] Furthermore, the flush water supply device 6 is equipped with a power outage operation device U that includes power outage manual operation sections U1, U2 that enable manual water supply and drainage operations during a power outage. The power outage manual operation units U1 and U2 of this power outage operation device U will be described in detail later, but they are equipped with a power outage water supply operation unit U1 that allows the water supply to the toilet body 4 to be stopped by manual operation, and a power outage drain operation unit U2 that allows the internal flow path S1 of the drain socket S to be opened and closed by manual operation.

[0028] Next, as shown in FIGS. 1 and 2, 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. Furthermore, as shown in FIG. 2, the flush toilet 1 of this embodiment is equipped with a cover member 44 that is removably attached to the rear side of the skirt portion 42. When attached to the toilet body 4, the cover member 44 is arranged to cover the side of each power outage manual operation unit U1, U2 (the left side when viewed from the front side of the toilet body 4).

[0029] Next, the power outage water supply operation unit U1 and the power outage drainage operation unit U2 of the power outage operating device U will be described in detail with reference to Figs. First, FIG. 3 is a perspective view of the power outage water supply operating unit of a flush toilet according to one embodiment of the present invention, seen diagonally from the front left. As shown in FIG. 3, the power outage water supply operating section U1 manually opens and closes the main valve 32 of the valve unit 28 during a power outage, thereby enabling the water supply to the toilet body 4 to be stopped. Specifically, this power outage water supply operation unit U1 comprises a fixed tube 46, an operation wire 48 for water supply operation (hereinafter referred to as the "water supply operation wire 48"), and a valve operation ring 50 which is a manually operated gripping portion (first gripping portion). One end of the fixed tube 46 (the end on the valve unit side) is fixed to a part of the valve unit 28.

[0030] On the other hand, as shown in Figures 3 and 4, the other end (tip) of the fixed tube 46 (cover member side end 46a) has a fixed portion 46b that is fixed to a part of the fixing member 52 that fixes the flush water supply device 6 to the toilet body 4. That is, as shown in FIGS. 3 and 4, the tip of the fixed tube 46 is provided with a fixing portion 46b for fixing the fixed tube 46 to a part of the fixing member 52 of the storage area V0. The fixing portion 46b has an insertion hole 46c through which the water supply control wire 48 can be inserted. The insertion hole 46c is formed so that the inner diameter increases toward the outside in the axial direction. Furthermore, the inner surface of this insertion hole 46c is formed as a curved surface that is convex toward the center of the insertion hole 46c, and is formed in a substantially conical shape that widens toward the outer tip of the insertion hole 46c in the axial direction. This allows the water supply operation wire 48 to be smoothly operated no matter what direction it is pulled from.

[0031] The water supply control wire 48 is provided so as to be insertable into the fixed tube 46 . One end of this water supply operation wire 48 (the end on the valve unit side) is connected to a part of the valve unit 28, which is the water supply unit, and more specifically, is connected to a part of a mechanism (not shown) that enables the diaphragm-type main valve 32 to be opened and closed. On the other hand, the other end (valve operation ring side end 48 a) of the water supply operation wire 48 is connected to the valve operation ring 50 . As a result, the water supply operation wire 48 serves as a pulling member that is pulled by pulling the valve operation ring 50, and when the valve operation ring 50 is pulled, the main valve 32 is opened and closed via the water supply operation wire 48 and the opening and closing mechanism (not shown) of the valve unit 28.

[0032] Furthermore, as shown in Figure 3, the water supply operation wire 48 is a flexible metal wire member, so when the cover member 44 is attached to the rear side of the skirt portion 42 of the toilet body 4 in the non-operating state (standby state) of the water supply operation unit U1 during a power outage, a portion of the water supply operation wire 48 is elastically bent by the cover member 44, and the valve operation ring 50 is directed vertically downward. As a result, a portion of the water supply operation wire 48 in an elastically bent state and the valve operation ring 50 connected to it and facing vertically downward are stored in a designated storage section (storage area V0) inside the cover member 44. As shown in Figure 3, when the cover member 44 is removed during a power outage operation, the water supply operation wire 48, which has been elastically bent in part, is released from the constraint of the cover member 44 and elastically returns to its original state, causing the valve operation ring 50 and part of the water supply operation wire 48 to protrude from within the storage area V0 to the outside (to the side). In addition, with regard to the valve operating ring 50 and water supply operating wire 48 shown in Figure 3, the standby state P1 in which they are stored within the storage area V0 is shown by solid lines, and the state P2 in which they have protruded outside (to the side) from within the storage area V0 is shown by dotted lines. Furthermore, since the water supply operation wire 48 is a flexible metal wire member, simply by removing the cover member 44 during a power outage operation, the water supply operation wire 48 itself also serves as a guide section G that guides the valve operation ring 50 from the standby state P1 to the protruding state P2. As a modification, an elastic member for applying a biasing force to the water supply operation wire 48 may be provided between the inner wall portion 54 and the valve operation ring 50, etc.

[0033] Next, FIG. 4 is a side view of the storage section for the power outage water supply operating section in a flush toilet according to one embodiment of the present invention. As shown in Figures 3 and 4, the storage section (storage area V0) of the power outage water supply operation section U1 is provided on the side of the toilet body 4, and more specifically, is formed between the side of the fixing member 52 of the flush water supply device 6 and the inside of the cover member 44. As shown in Figure 4, the fixing member 52 has an inner wall portion 54 that holds the end portion 46a of the fixing tube 46, and an outer wall portion 56 that is located outside the inner wall portion 54 in the left-right direction of the toilet body 4.

[0034] Next, as shown in FIG. 4, an opening 58 is provided in the upper portion of the outer wall portion 56 of the fixing member 52, allowing the water supply operation wire 48 to be inserted therethrough. When viewed from the side, this opening 58 has an upper opening edge 60 whose upper edge is formed in a convex curve facing upward, and a front opening edge 62 and a rear opening edge 64 which extend downward from the front and rear lower ends of this upper opening edge 60, respectively. In addition, each of the upper opening edge 60, the front opening edge 62, and the rear opening edge 64 is chamfered so that it can come into contact with a part of the water supply operation wire 48 when operating the water supply operation unit U1 during a power outage, and forms a guide portion G that guides the water supply operation wire 48 in the operation direction.

[0035] As a result, as shown in Figures 3 and 4, in the standby state with the cover member 44 attached, the valve operating ring 50 is stored in the storage area V0, and the water supply operating wire 48 near the connection portion of this valve operating ring 50 is stored in a pre-elastically bent state. When the cover member 44 is removed, the valve operating ring 50 in the storage area V0 is guided to jump out together with the water supply operating wire 48 due to the elastic force of the water supply operating wire 48. Then, as shown in Figure 4, the valve operating ring 50 is pulled in any of the upper operating direction H1, lower operating direction L1, front operating direction F1, and rear operating direction R1, or in a diagonal direction midway between the operating directions H1, L1, F1, and R1, so that a portion of the water supply operating wire 48 can come into contact with any one of the chamfered portions of the upper opening edge 60, front opening edge 62, or rear opening edge 64 in the guide section G.

[0036] For example, when operating the power outage water supply operation unit U1 during a power outage, first, the cover member 44 is removed, thereby opening up the power outage water supply operation unit U1 and the side of its storage area V0, and the valve operation ring 50 in standby state P1 and part of the water supply operation wire 48 protrude from within the storage area V0 to the outside (side). By manually pulling the valve operating ring 50 in this protruding state P2, the water supply operating wire 48 is pulled a predetermined length in any one of the predetermined operating directions H1, L1, F1, R1, etc. Thereafter, by returning the water supply operating wire 48 to its original position, the main valve 32 is opened via its opening / closing mechanism (not shown), and water supply by the valve unit 28 is manually performed. After that, the valve operating ring 50 is manually pulled again to pull the water supply operating wire 48 a predetermined length, and then the water supply operating wire 48 is returned to its original position, which closes the main valve 32 via the opening / closing mechanism (not shown), and the water is manually stopped by the valve unit 28.

[0037] Next, Figure 5 is a partially enlarged view of the power outage flush operating unit in the flush toilet according to one embodiment of the present invention shown in Figure 2. Furthermore, Figure 6 is a perspective view of the power outage flush operating unit in the flush toilet according to one embodiment of the present invention, seen diagonally from the front left. As shown in Figures 1, 5 and 6, the power outage drainage operation unit U2 includes a fixed tube 66, an operation wire 68 for drainage operation (hereinafter referred to as "drainage operation wire 68"), a flapper device 70, and a flapper operation ring 72. First, as shown in FIG. 1, the flapper device 70 is a socket opening / closing portion that includes a flapper valve 70a that is provided in the internal flow path S1 of the drain socket S so as to be able to open and close. Furthermore, the flapper valve 70a keeps the internal flow path S1 of the drain socket S open during normal use.

[0038] Next, one end of the fixed tube 66 is fixed to a part of the flapper device 70 , and the other end is fixed to a holder 74 . The drainage operation wire 68 is a metal wire member that is provided so as to be insertable into the fixed tube 66 . Furthermore, one end of the drain operation wire 68 on the flapper device 70 side is connected to a part of a mechanism (not shown) that enables the flapper valve 70a of the flapper device 70 to be opened and closed. On the other hand, the other end of the drainage operation wire 68 is connected to a flapper operation ring 72 via a flexible connecting loop 68a. The flapper operating ring 72 serves as a second gripping portion that is manually operated.

[0039] As a result, as shown in Figure 6, in the non-power outage operation state (standby state) in which the cover member 44 is attached to the toilet body 4, the flapper operation ring 72 and connecting loop 68a of the power outage drain operation unit U2 are stored in a storage area common to the storage area V0 in which the power outage water supply operation unit U1 is stored. At this time, the flapper operation ring 72 of the power outage drainage operation unit U2 is positioned below the valve operation ring 50 of the power outage water supply operation unit U1. In addition, in the event of a power outage, the cover member 44 can be removed to open the drainage operation section U2 and the sides of the storage area V0, and due to the flexibility of the connecting loop 68a, the flapper operation ring 72 and the connecting loop 68a can protrude from within the storage area V0 to the outside (side). In addition, with regard to the flapper operating ring 72 and connecting loop 68a shown in Figure 6, the standby state P3 in which they are stored within the storage area V0 is shown by solid lines, and the state P4 in which they have protruded outside (to the side) from within the storage area V0 is shown by dotted lines. By manually pulling the flapper operating ring 72, the drainage operating wire 68 is pulled via the connecting loop 68a. As a result, the drain operation wire 68 operates the opening and closing mechanism (not shown) of the flapper valve 70a of the flapper device 70, making it possible to drain water from the drain socket S and to store water in the bowl portion 8 of the toilet body 4.

[0040] For example, when operating the power outage drainage operation unit U2 during a power outage, first, the cover member 44 is removed, which opens up the power outage drainage operation unit U2 and the side of its storage area V0, and causes the flapper operation ring 72 and part of the connecting loop 68a to protrude from within the storage area V0 to the outside (side). By manually pulling the flapper operation ring 72 in this protruding state, the drain operation wire 68 is pulled a predetermined length in any of the predetermined operation directions H1, L1, F1, R1, etc. After that, by returning the drain operation wire 68 to its original position, the flapper valve 70a can be closed via the opening / closing mechanism (not shown) of the flapper valve 70a. After that, the flapper operating ring 72 is manually pulled again to pull the drain operation wire 68 a predetermined length, and then the drain operation wire 68 is returned to its original position again, whereby the flapper valve 70a opens via the opening and closing mechanism (not shown) of the flapper valve 70a, the internal flow path S1 in the drain socket S is opened, and water can be drained from the drain trap section 12 of the toilet body 4 through the drain socket S to the drain pipe D. In addition, since the flapper valve 70a of the flapper device 70 is normally in an open state, the flapper valve 70a may be maintained in a closed state via an opening / closing mechanism (not shown) of the flapper valve 70a as long as the drainage operation wire 68 is maintained in a pulled state by a predetermined length by manually pulling the flapper operation ring 72.

[0041] Next, an example of manual operation of the power outage water supply operating section U1 and the power outage water drain operating section U2 during a power outage will be described with reference to Figs. First, the cover member 44 is removed to open the power outage water supply operation unit U1, the power outage water drain operation unit U2, and the sides of their storage area V0. As a result, the valve operating ring 50 and part of the water supply operating wire 48 in the standby state P1, and the flapper operating ring 72 and part of the connecting loop 68a in the standby state P3, protrude from within the storage area V0 to the outside (to the side). First, the valve operating ring 50 is manually pulled to pull the water supply operating wire 48 a predetermined length, and then the water supply operating wire 48 is returned to its original position, whereupon the main valve 32 opens via its opening / closing mechanism (not shown), and the water supply operation by the valve unit 28 is manually performed. As a result, water starts to be discharged from the main water supply passage 2 through the rim-side water supply passage 2a and from the rim water spout 14a of the toilet body 4 into the bowl portion 8 (rim spouting).

[0042] Next, by manually pulling the flapper operation ring 72 of the power outage drain operation unit U2, the drain operation wire 68 is pulled a predetermined length, and while doing so, the flapper valve 70a closes via the opening and closing mechanism (not shown) of the flapper valve 70a. 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.

[0043] 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 pulling of the flapper operating ring 72 of the power outage drain operating unit U2 is stopped and the drain operating wire 68 is returned to its original position, causing the flapper valve 70a to open via the opening and closing mechanism (not shown) of the flapper valve 70a. 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, the valve operating ring 50 is manually pulled to pull the water supply operating wire 48 by a predetermined length, and then the water supply operating wire 48 is returned to its original position. As a result, the main valve 32 is closed via an opening / closing mechanism (not shown) of the main valve 32, and the water stopping operation by the valve unit 28 is manually performed. Then, the discharge of water from the main water supply passage 2 through the rim-side water supply passage 2a and from the rim water spout 14a of the toilet body 4 into the bowl portion 8 (rim water spouting) is stopped. As a result, a series of water supply and drainage operations related to toilet flushing during a power outage are completed.

[0044] Next, the operation of the flush toilet 1 according to one embodiment of the present invention will be explained with reference to FIGS. First, with a flush toilet 1 according to one embodiment of the present invention, the grips of the power outage manual operation units U1 and U2 are stored in a storage area V0 covered by a cover member 44 during standby. On the other hand, since the cover member 44 is removed during power outage operation and pops out from within the storage area V0 to the outside, when the user starts the power outage operation, the user can easily grasp the gripping parts 50, 72 that have popped out from within the storage area V0 of the power outage manual operation parts U1, U2 by simply removing the cover member 44. Therefore, when performing power outage operations, the gripping portions 50, 72 of the power outage manual operation units U1, U2 can be accessed quickly, and subsequent power outage operations can be carried out smoothly. As a result, the visibility and operability of the manual operation units U1 and U2 during a power outage can be improved.

[0045] Furthermore, according to the flush toilet 1 of this embodiment, the manual operation unit U during power outages is equipped with two operation units: a water supply operation unit U1 during power outages that enables the water supply to the toilet body 4 to be stopped, and a drainage operation unit U2 during power outages that enables the drainage operation from the drain socket S and the storage of water in the bowl portion 8 of the toilet body 4. This allows the user to easily grasp the position of the valve operating ring 50 of the power outage water supply operating unit U1, which is in a state P2 protruding from the storage area V0 to the outside, simply by removing the cover member 44 when starting power outage operations. Therefore, a user who is about to start operating the power outage manual operation unit U can be guided to the effect that the water supply stop operation using the power outage water supply operation unit U1 should take priority over the drainage operation using the power outage drainage operation unit U2, thereby enabling appropriate water supply and drainage operations to be performed when responding to a power outage.

[0046] Furthermore, with the flush toilet 1 according to this embodiment, the storage area V0 forms a common storage area for the power outage water supply operation unit U1 and the power outage drain operation unit U2, located inside the cover member 44. Additionally, the first grip portion (valve operation ring 50) of the power outage water supply operation unit U1 and the second grip portion (flapper operation ring 72) of the power outage drain operation unit U2 are each stored in the common storage area V0 for the power outage water supply operation unit U1 and the power outage drain operation unit U2. As a result, when starting power outage operations, the user can easily access the first grip portion (valve operation ring 50) of the common storage area V0 and the second grip portion (flapper operation ring 72) of the power outage drainage operation portion U2 simply by removing the cover member 44. Furthermore, the first grip portion (valve operation ring 50) and the second grip portion (flapper operation ring 72) of the power outage drain operation portion U2 are provided in the common storage area V0, making them easy to operate.

[0047] Furthermore, with the flush toilet 1 according to this embodiment, the power outage water supply operation unit U1 is located above the power outage drain operation unit U2 within the common storage area V0 provided on the side of the toilet body 4. This makes it easier for a user looking at the power outage manual operation units U1, U2 from above during a power outage to grasp (visually recognize) the power outage water supply operation unit U1 than the power outage drain operation unit U2. Therefore, a user who is about to start operating the power outage manual operation unit U (U1, U2) can be guided to understand that the water supply stop operation using the power outage water supply operation unit U1 should take priority over the drainage operation using the power outage drainage operation unit U2, allowing appropriate water supply and drainage operations to be performed when responding to a power outage.

[0048] Furthermore, with the flush toilet 1 of this embodiment, when the user begins the power outage operation, he or she can remove the cover member 44, and the first gripping portion (valve operating ring 50) and the traction member (water supply operating wire 48) connected to it can be guided in the operating direction by the guide portion G of the power outage water supply operating portion U1, which has protruded from within the storage area V0 of the power outage water supply operating portion U1. In addition, when the user pulls the towing member (water supply operation wire 48) together with the first gripping portion (valve operation ring 50) of the power outage water supply operation unit U1 in the operation directions H1, L1, F1, and R1, the guiding portion G of the power outage water supply operation unit U1 can prevent deformation such as kinking of the towing member (water supply operation wire 48), allowing the water supply operation wire 48 and valve operation ring 50 to be pulled smoothly. Therefore, the load on the first grip portion (valve operation ring 50) and the pulling member (water supply operation wire 48) of the water supply operation unit U1 during power outage operation can be reduced, improving operability.

[0049] Furthermore, according to the flush toilet 1 of this embodiment, the traction member (water supply operation wire 48) is a flexible metal wire member, and when the user begins the power outage operation, they simply remove the cover member 44, and the elastic force of the flexible metal wire member allows the first grip portion (valve operation ring 50) of the power outage water supply operation unit U1 to easily pop out from within the storage area V0 to the outside. Thereafter, by pulling the first gripping portion (valve operating ring 50) of the power outage water supply operating portion U1 in any of the upper operating direction H1, lower operating direction L1, front operating direction F1, and rear operating direction R1, or in a diagonal direction intermediate between the operating directions H1, L1, F1, and R1, the main valve 32 of the water supply unit (valve unit 28) can be opened or closed, thereby enabling smooth water supply and stop operations of the water supply unit (valve unit 28) during a power outage. Furthermore, the guide section G of the water supply operation unit U1 during power outages is provided above and to the side of the fixed member 52 in the storage area V0 with an opening 58 through which the towing member (water supply operation wire 48) can be inserted. Furthermore, the upper opening edge 60, front opening edge 62, and rear opening edge 64 of this opening 58 are each chamfered so as to be able to come into contact with a part of the water supply operation wire 48 when the water supply operation unit U1 during power outages is towed. This reduces the frictional resistance at the contact point between the chamfered portion and the water supply operation wire 48, making it easier to guide the valve operation ring 50 and the water supply operation wire 48 in the operating direction during towing operation. Furthermore, when the user pulls the water supply operation wire 48 together with the valve operation ring 50 of the power outage water supply operation unit U1 in any of the upper operation direction H1, lower operation direction L1, front operation direction F1, or rear operation direction R1, or in a diagonal direction between the operation directions H1, L1, F1, and R1, the guide portion G of the power outage water supply operation unit U1 can appropriately guide the movement of the water supply operation wire 48, thereby preventing deformation such as kinking of the water supply operation wire 48 and allowing the valve operation ring 50 and water supply operation wire 48 to be pulled smoothly. As a result, the load on the valve operation ring 50 and the water supply operation wire 48 of the water supply operation unit U1 during a power outage can be reduced, further improving operability.

[0050] Furthermore, with the flush toilet 1 according to this embodiment, in the storage area V0 of the power outage water supply operating unit U1 in standby mode with the cover member 44 attached, the valve operating ring 50 is stored with the water supply operating wire 48 near the connection with the valve operating ring 50 elastically bent in advance. When the cover member 44 is removed during a power outage operation, the water supply operation wire 48 can guide the valve operation ring 50 in the storage area V0 to jump out to the outside by its elastic force. Thereafter, when the valve operating ring 50 of the power outage water supply operating unit U1 is pulled in any of the upper operating direction H1, lower operating direction L1, front operating direction F1, or rear operating direction R1, or in a diagonal direction midway between the operating directions H1, L1, F1, and R1, a part of the water supply operating wire 48 comes into contact with any one of the chamfered portions of the upper opening edge 60, front opening edge 62, or rear opening edge 64 in the guide section G. This makes it possible to reduce frictional resistance at the contact portion between this chamfered portion and the water supply control wire 48. Therefore, the pulling operation of the valve operating ring 50 and the water supply operating wire 48 can be carried out smoothly. As a result, the load on the valve operation ring 50 and the water supply operation wire 48 of the water supply operation unit U1 during a power outage can be reduced, further improving operability.

[0051] Furthermore, according to the flush toilet 1 of this embodiment, a fixing portion 46b is provided at the tip of the fixing tube 46, which partially covers the water supply operation wire 48, for fixing the water supply operation wire 48 to a part of the fixing member 52 in the storage area V0. In addition, the insertion hole 46c in this fixed portion 46b, which allows the water supply operation wire 48 to be inserted therethrough, is formed so that its inner diameter increases toward the outside in the axial direction, and the inner surface of this insertion hole 46c is formed in a convex curved surface toward the center of the insertion hole 46c. This makes it possible to suppress the frictional resistance at the contact point between the water supply operation wire 48 and the inner surface of the insertion hole 46c regardless of the direction from which the water supply operation wire 48 is pulled, thereby enabling smooth operation of the valve operation ring 50 and the water supply operation wire 48 during the pulling operation. In addition, when the user pulls the water supply operation wire 48 in the operating direction together with the valve operation ring 50 of the water supply operation unit U1 during a power outage, the convex curved inner surface of the insertion hole 46c of the fixing part 46b can appropriately guide the movement of the water supply operation wire 48 when the valve operation ring 50 is pulled, thereby preventing deformation such as kinking of the water supply operation wire 48 and allowing the valve operation ring 50 and water supply operation wire 48 to be pulled smoothly. As a result, the load on the valve operation ring 50 and the water supply operation wire 48 of the water supply operation unit U1 during a power outage can be reduced, further improving operability.

[0052] As a modified example of the flush toilet 1 according to the embodiment of the present invention described above, by removing the cover member 44, the power outage water supply operation unit U1, the power outage drain operation unit U2, and the sides of their storage area V0 are opened, so that the valve operation ring 50 in standby state P1 and part of the water supply operation wire 48 protrude from within the storage area V0 to the outside (side), while the flapper operation ring 72 and part of the connecting loop 68a do not protrude from within the storage area V0 to the outside (side). As a result, since only the valve operating ring 50 and a portion of the water supply operating wire 48 are arranged to protrude from within the storage area V0 to the outside (side), the user can easily grasp the location of the valve operating ring 50 that should be operated first, and can operate the valve operating ring 50 first over the flapper operating ring 72. Furthermore, as yet another modification of the flush toilet 1 according to the embodiment of the present invention described above, the valve operating ring 50 may not protrude, but the flapper operating ring 72 may be provided so as to protrude. In addition, the valve operating ring 50 may be placed at the bottom and the flapper operating ring 72 may be placed at the top, and the operating part that is to be operated preferentially may be placed at the top and arranged to protrude in accordance with the priority of the power outage operating mechanism. Furthermore, the power outage manual operation units U1 and U2 for manually performing flushing operations on the toilet body 4 during a power outage are not limited to the present embodiment, and any form can be adopted, such as a button-type operation unit or a lever-type operation unit, as long as the operations required for flushing are activated by some kind of manual operation.

[0053] In the flush toilet 1 according to one embodiment of the present invention described above, the configuration of the operation unit for responding to power outages has been described, employing a valve operation ring 50 for the power outage water supply operation unit U1 and a flapper operation ring 72 for the power outage drainage operation unit U2, but this is not limited to such a configuration, and the invention can also be applied to other configurations employing an operation unit other than the operation unit for responding to power outages, or an operation unit that performs operations other than those of a functional unit (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.
