[0008] In the present invention, the inlet of the stirring section is preferably disposed above the bottom surface of the stirring section.

[0009] According to the present invention configured in this manner, the inlet of the agitating section is positioned above the bottom surface of the agitating section, so that the wash water can be agitated more effectively within the agitating section.

[0010] In the present invention, the outlet of the stirring section is preferably disposed below the inlet.

[0011] According to the present invention configured in this manner, the outlet of the agitating section is positioned lower than the inlet, so that the wash water can be agitated more effectively within the agitating section.

[0012] In the present invention, preferably, a wall surface is formed in front of the inlet in the stirring section.

[0013] According to the present invention configured in this manner, a wall surface is formed in front of the inlet in the agitating section, so that the wash water can be agitated more effectively in the agitating section.

[0014] In the present invention, the width of the stirring section is preferably larger than the width of the inlet.

[0015] According to the present invention configured in this manner, the width of the agitating section is greater than the width of the inlet, so that the wash water can be agitated more effectively within the agitating section.

[0016] In the present invention, the bottom surface of the agitating section is preferably continuous with the bottom surface of the flow regulating section so as to form a substantially flat surface.

[0017] According to the present invention configured in this manner, the bottom surface of the agitation section is continuous with the bottom surface of the straightening section so as to form an almost flat surface, so that the agitated cleaning water can be smoothly guided into the straightening section.

[0018] In the present invention, the opening cross-sectional area of ​​the rim spout port is preferably smaller than the flow path cross-sectional area of ​​the rim water conduit.

[0019] According to the present invention configured in this manner, the opening cross-sectional area of ​​the rim water outlet is smaller than the flow path cross-sectional area of ​​the rim water conduit, making it possible to make the discharge pattern of the flush water discharged from the rim water outlet more stable. [Effects of the Invention]

[0020] According to the flush toilet of the present invention, the discharge pattern of flush water discharged from the rim spout can be stabilized, allowing the bowl portion to be sufficiently cleaned. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0022] A flush toilet according to an embodiment of the present invention will now be described with reference to the drawings. First, the basic structure of a flush toilet 1 according to an embodiment of the present invention will be explained with reference to FIGS. Fig. 1 is a plan view of a flush toilet according to an embodiment of the present invention, and Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1. In Fig. 1, the dashed lines indicate the rim water conduit 12 and the jet water conduit 18, and in Fig. 2, the two-dot chain line indicates the rim water conduit 12 and the dashed line indicates the jet water conduit 16. In this specification, when viewing the flush toilet from the front, the near side will be referred to as the front side, the far side as the rear side, the right side as the right side, and the left side as the left side.

[0023] As shown in Figures 1 and 2, the flush toilet 1 according to an embodiment of the present invention is a siphon jet type flush toilet that uses a jet of water to create a siphon action to discharge waste. Note that while the flush toilet 1 according to an embodiment of the present invention will be described as a siphon jet type flush toilet, it is not limited to this form and can take other forms, such as a wash-down toilet that flushes away waste with the flow of water caused by a drop in water, or a siphon type flush toilet that discharges waste by creating a siphon action with a rim water discharge.

[0024] As shown in Figure 1, a flush toilet 1 comprises a toilet body 2 and a flush water tank 4 located at the upper rear of the toilet body 2. The toilet body 2 and flush water tank 4 are integrally formed from ceramic. A lever handle (not shown) is provided on the flush water tank 4, and the user operates the lever handle to flush the toilet.

[0025] The toilet body 2 is equipped with a bowl portion 6 that receives waste, a drain trap pipe 8 that is located at the bottom of the bowl portion 6 and that discharges waste by siphon action, a rim spout 10 that spouts water from the rim, a rim water conduit 12 that supplies flush water to the rim spout 10, a jet spout 14 that spouts water in a jet, and a jet water conduit 16 that supplies flush water to the jet spout 14. Note that in the flush toilet 1 according to the embodiment of the present invention, the rim water conduit 12 and the jet water conduit 16 are provided separately, but this is not the only embodiment, and the rim water conduit 12 and jet water conduit 16 may also be configured as a single water conduit.

[0026] Bowl portion 6 has a bowl-shaped waste receiving surface 18, a rim portion 20 that is formed along the upper edge of bowl portion 6 and forms an inner circumferential surface 20a that overhangs inward, and a shelf surface 22 formed between waste receiving surface 18 and rim portion 20. Bowl portion 6 also has a pot portion 24 that is formed in the area below waste receiving surface 18 and connected to drain trap pipe 8. A water seal W is formed inside pot portion 24.

[0027] The drain trap pipe 8 has an inlet 8a, an ascending pipe 8b extending upward from the inlet 8a, a descending pipe 8c extending downward from the ascending pipe 8b, and a top 8d located between the descending pipe 8c and the ascending pipe 8b and defining the seal water level. The lower end of the descending pipe 8c of the drain trap pipe 8 is connected to a drain pipe (not shown) via a drain socket (not shown).

[0028] The rim spout 10 is formed in the rim portion 20, and is positioned on the rear side of the bowl portion 6 and near the center in the left-right direction. Flush water is spouted from the rim spout 10 along the inner circumferential surface 20a of the rim portion 20, and swirls counterclockwise on the ledge surface 22 along the inner circumferential surface 20a of the rim portion 20. As the flush water swirls on the ledge surface 22 in this way, it flows down from the ledge surface 22 onto the waste receiving surface 18, cleaning the waste receiving surface 18. Note that while the flush toilet 1 according to the embodiment of the present invention has been described as having only one rim spout 10, the configuration is not limited to this, and other configurations are also possible, for example, a configuration in which two or more rim spouts are provided.

[0029] One end of the rim conduit 12 is connected to the rim drain outlet 4b formed in the bottom surface 4a of the flush water tank 4, and the other end is connected to the rim spout 10. In a plan view, the rim conduit 12 is formed so that it extends forward from the rim drain outlet 4b of the flush water tank 4, bends gently to the right, and then bends at an almost right angle to the left (see Figure 1). Flush water is supplied to the rim conduit 12 from the flush water tank 4, and the head pressure of this flush water causes flush water to be spouted from the rim spout 10.

[0030] Jet water spout 14 is formed in the bottom of bowl portion 6. Jet water spout 14 is positioned opposite inlet 8a of drain trap pipe 8 and is directed toward inlet 8a of drain trap pipe 8. Flush water is spouted from jet water spout 14 toward inlet 8a of drain trap pipe 8, causing a siphon effect to occur in a relatively short time.

[0031] One end of the jet water conduit 16 is connected to a jet drain outlet 4c formed in the bottom surface 4a of the flush water tank 4, and the other end is connected to the jet spout 14. The jet water conduit 16 is equipped with a main conduit 16a that extends forward from the jet drain outlet 4c of the flush water tank 4, a first jet conduit 16b that bends to the left from the downstream end of the main conduit 16a and extends forward, a second jet conduit 16c that bends to the right from the downstream end of the main conduit 16a and extends forward, and a junction flow path 16d where the downstream ends of the first jet conduit 16b and second jet conduit 16c join and extend rearward to connect with the jet spout 14 (see Figure 1). Flush water is supplied to the jet conduit 16 from the flush water tank 4, and the head pressure of this flush water causes flush water to be spouted from the jet spout 14.

[0032] The flush water tank 4 is a gravity-fed tank that stores flush water supplied from a water supply source (not shown), such as a tap, and supplies this stored flush water to the toilet body using gravity. A rim drain outlet 4b, which drains water into the rim water conduit 12, and a jet drain outlet 4c, which drains water into the jet water conduit 16, are formed in the bottom surface 4a of the flush water tank 4. The rim drain outlet 4b is positioned forward of the jet drain outlet 4c. A rim drain valve and a jet drain valve (not shown) are provided inside the flush water tank 4 to open and close the rim drain outlet 4b and jet drain outlet 4c, respectively. Note that, in the flush toilet 1 according to the embodiment of the present invention, a form in which the flush water tank is a gravity-fed tank has been described, but the present invention is not limited to this form and other forms are possible, for example the flush water tank may be a pressurized or pressure-accumulating tank. Furthermore, in the flush toilet 1 according to the embodiment of the present invention, the rim drain outlet 4b and the jet drain outlet 4c are provided separately, but this is not limited to this embodiment, and there may also be an embodiment in which the rim drain outlet 4b and the jet drain outlet 4c are configured as a single drain outlet.

[0033] The flush water tank 4 is equipped with a water pressure drive mechanism (not shown) that is driven by the water supply pressure of flush water supplied from a water supply source, for example, and the water pressure drive mechanism is driven by the user operating a lever handle, causing the rim drain valve and jet drain valve to operate at different times. This causes the rim drain outlet 4b and the jet drain outlet 4c to open and close at different times, causing flush water to be discharged from the rim water spout 10 and the jet water spout 14 at different times. Specifically, after flushing begins, flush water is first discharged from the rim water spout 10, then, while water is still being discharged from the rim water spout 10, flush water is discharged from the jet water spout 14, and after water discharge from the jet water spout 14 stops, flush water from the rim water spout 14 returns the seal water W to its initial state.

[0034] Next, the rim water conduit 12 of the flush toilet 1 according to an embodiment of the present invention will be described in detail with reference to Figure 3. Figure 3 is a cross-sectional view taken along line III-III in Figure 1.

[0035] As shown in FIG. 3, the rim water conduit 12 includes, from upstream to downstream, an inlet 12a, a water pooling section 26, a throttle section 28, a stirring section 30, a flow straightening section 32, and an outlet 12b.

[0036] First, as shown in FIG. 3, the inlet 12a of the rim water conduit 12 opens upward, and the rim drain outlet 4b of the flush water tank 4 is connected to this inlet 12a.

[0037] 3, the water accumulation section 26 of the rim water conduit 12 is formed so that the bottom surface 12c of the rim water conduit 12 is recessed downwards. In the standby state before flushing, flush water accumulates in the water accumulation section 26 up to the accumulated water level WL. As a result, flush water supplied from the rim drain outlet 4b of the flush water tank 4 to the inlet 12a of the rim water conduit 12 collides with the flush water accumulated in the water accumulation section 26, and the momentum of this flush water washes the flush water accumulated in the water accumulation section 26 downstream.

[0038] As shown in Figure 3, the throttle section 28 of the rim water conduit 12 is formed downstream of the pooling section 26. The flow path cross-sectional area of ​​the throttle section 28 (cross-sectional area perpendicular to the flow direction of the flush water) is set to be smaller than the opening cross-sectional area of ​​the rim drain outlet 4b of the flush water tank 4. This increases the flow rate of the flush water in the throttle section 28.

[0039] As shown in Figure 3, the agitation section 30 of the rim water conduit 12 is formed downstream of the constriction section 28. The agitation section 30 forms a space that suddenly expands from the constriction section 28. The flush water that flows into the agitation section 30 is agitated in the vertical direction within the agitation section 30, and then flows downstream. As a result, the flush water is agitated in the vertical direction within the agitation section 30, and is thereby temporarily retained within the agitation section 30.

[0040] As shown in Figure 3, the flow straightening section 32 of the rim water conduit 12 is formed downstream of the agitation section 30. The flow straightening section 32 is formed so that it extends at an angle downwards towards the rim water outlet 10. This allows the flow direction of flush water to be straightened in the flow straightening section 32 and flow towards the rim water outlet 10.

[0041] As shown in FIG. 3, the outlet 12b of the rim water conduit 12 is connected to the rim spout 10 and opens toward the bowl portion 6.

[0042] Next, the stirring section 30 and rectifying section 32 of the rim water conduit 12 of a flush toilet 1 according to an embodiment of the present invention will be described in detail with reference to Figures 4 to 6. Figure 4 is an enlarged cross-sectional view of a portion of Figure 3, Figure 5 is a cross-sectional view taken along line VV in Figure 4, and Figure 6 is a cross-sectional view taken along line VI-VI in Figure 4.

[0043] First, as shown in Figure 4, the agitation section 30 of the rim water conduit 12 is formed in a rectangular parallelepiped shape, forming a relatively large space S inside it. A rear wall surface 30b is formed on the rear side (upstream side) of the agitation section 30, extending vertically upward from the rear end of the bottom surface 30a of the agitation section 30. A front wall surface 30d is formed on the front side (downstream side) of the agitation section 30, extending vertically downward from the front end of the top surface 30c of the agitation section 30. The rear wall surface 30b and the front wall surface 30d are arranged to face each other.

[0044] As shown in FIGS. 4 and 5, an inlet 30e is formed in the rear wall surface 30b of the agitating section 30, through which cleaning water flows into the agitating section 30. The inlet 30e of the agitating section 30 is located above the vertical center of the rear wall surface 30b, and is formed at the upper end of the rear wall surface 30b. The inlet 30e of the agitating section 30 is formed in a flat, approximately rectangular shape (see FIG. 5). The inlet 30e of the agitating section 30 is connected to the throttled section 28, and is continuous with the upper surface 30c of the agitating section 30 so as to form an approximately flat surface with the upper surface of the throttled section 28. As shown in FIG. 5, the width of the inlet 30e of the agitating section 30 is smaller than the width of the rear wall surface 30b of the agitating section 30 (the width of the rear wall surface 30b of the agitating section 30 is larger than the width of the inlet 30e of the agitating section 30).

[0045] 4 and 5, an outlet 30f for discharging cleaning water from the agitating section 30 is formed in the front wall surface 30d of the agitating section 30. The outlet 30f of the agitating section 30 is located below the center in the up-down direction of the front wall surface 30d, and is formed at the lower end of the front wall surface 30d. The outlet 30f of the agitating section 30 is formed in a flat, approximately rectangular shape (see FIG. 6). The outlet 30f of the agitating section 30 is connected to the flow rectifying section 32, and the bottom surface 30a of the agitating section 30 is continuous with the bottom surface 32a of the flow rectifying section 32 so as to form an approximately flat surface.

[0046] 4, a front wall surface 30d is formed in front of the inlet 30e of the agitation unit 30. Specifically, the front wall surface 30d is formed in the area obtained by horizontally projecting the opening cross section of the inlet 30e of the agitation unit 30. In this way, the cleaning water flowing in from the inlet 30e of the agitation unit 30 collides with the front wall surface 30d.

[0047] As shown in Figure 4, the flow straightening section 32 of the rim conduit 12 is connected to the outlet 30f of the agitation section 30. The flow straightening section 32 is designed so that its flow path cross-sectional area (cross-sectional area perpendicular to the flow direction of the flush water) is roughly constant from upstream to downstream. The opening cross-sectional area of ​​the outlet 12b of the rim conduit 12 (rim spout 10) is designed to be the smallest of all the sections of the rim conduit 12.

[0048] As shown in Figure 4, the bottom surface 32a of the flow rectification section 32 slopes downward at a substantially constant angle toward the downstream side. The top surface 32b of the flow rectification section 32 slopes downward toward the downstream side, generally parallel to the bottom surface 32a of the flow rectification section 32. The height position of the outlet 12b of the rim conduit 12 is set to be the lowest within the rim conduit 12.

[0049] Next, the operation of the flush toilet 1 according to this embodiment of the present invention will be explained with reference to FIG. FIG. 7 is a schematic diagram showing flush water flowing through the agitation section 30 and the flow straightening section 32 immediately after the start of flushing of a flush toilet 1 according to an embodiment of the present invention.

[0050] First, when the user operates the lever handle and the rim drain valve in the flush water tank 4 opens, flush water is supplied into the rim water conduit 12 from the rim drain outlet 4b.

[0051] The flush water supplied from the rim drain outlet 4b flows into the water reservoir 26 and flows into the throttle section 28 while pushing the flush water stored in the water reservoir 26. The flow rate of the flush water that flows into the throttle section 28 is increased, and the flush water flows into the agitation section 30 from the inlet 30e of the agitation section 30.

[0052] The flush water that flows in from the inlet 30e of the agitator 30 flows forward and hits the front wall surface 30d. When the flush water hits the front wall surface 30d, its flow direction changes from forward to downward. The flush water then flows downward and hits the bottom surface 30a. When the flush water hits the bottom surface 30a, its flow direction changes from downward to backward. The flush water then flows backward and hits the rear wall surface 30b. When the flush water hits the rear wall surface 30b, its flow direction changes from backward to upward. After hitting the rear wall surface 30b, the flush water flows toward the outlet 30f of the agitator 30. In this way, the flush water that flows in from the inlet 30e of the agitator 30 is agitated in the vertical direction within the agitator 30, and after temporarily remaining there, flows out from the outlet 30f of the agitator 30.

[0053] Flush water that flows into the flow straightening section 32 flows downward toward the rim spout 10. The flow straightening section 32 has a substantially constant flow path cross-sectional area, and the bottom surface 32a and top surface 32b extend substantially parallel to each other, so the flow direction of the flush water flowing within the flow straightening section 32 is aligned.

[0054] Flush water that has flowed through the flow straightening section 32 is discharged from the rim water outlet 10 into the bowl section 6. Because the opening cross-sectional area of ​​the rim water outlet 10 is relatively small, the flow rate of the flush water increases as it passes through the rim water outlet 10, and the flush water is discharged from the rim water outlet 10 into the bowl section 6. This stabilizes the discharge pattern of the flush water discharged from the rim water outlet 10, enabling the bowl section 6 to be thoroughly cleaned.

[0055] According to the flush toilet 1 of this embodiment, the rim water conduit 12 is an enlarged space S having an inlet 30e and an outlet 30f, and is provided with an agitation section 30 for agitating the flush water, and downstream of this agitation section 30 is provided a rectification section 32 which is connected to the outlet 30f and rectifies the agitated flush water, so that the flush water is rectified after being agitated and then discharged from the rim spout 10, and the discharge pattern of the flush water discharged from the rim spout 10 can be stabilized, thereby enabling the bowl section 6 to be sufficiently cleaned.

[0056] Furthermore, according to the flush toilet 1 of this embodiment, the inlet 30e of the agitation unit 30 is positioned above the bottom surface 30a of the agitation unit 30, so the flush water can be agitated more effectively within the agitation unit 30.

[0057] According to the flush toilet 1 of this embodiment, the outlet 30f of the agitation section 30 is positioned lower than the inlet 30e, so the flush water can be agitated more effectively within the agitation section 30.

[0058] Furthermore, according to the flush toilet 1 of this embodiment, a front wall surface 30d is formed in front of the inlet 30e inside the agitation section 30, so flush water can be agitated more effectively inside the agitation section 30.

[0059] According to the flush toilet 1 of this embodiment, the width of the agitation section 30 is greater than the width of the inlet 30e, so the flush water can be agitated more effectively within the agitation section 30.

[0060] Furthermore, according to the flush toilet 1 of this embodiment, the bottom surface 30a of the agitation section 30 is continuous with the bottom surface 32a of the rectification section 32 so as to form an approximately flat surface, so that the agitated flush water can be smoothly guided into the rectification section 32.

[0061] According to the flush toilet 1 of this embodiment, the opening cross-sectional area of ​​the rim spout 10 is smaller than the flow path cross-sectional area of ​​the rim water conduit 12, making it possible to make the discharge pattern of flush water discharged from the rim spout 10 more stable.

[0062] Although the embodiment of the present invention has been described above, various modifications can be made to the above-described embodiment. [Explanation of symbols]
