[Technical Field]

[0001] The present disclosure relates to toilet bowl systems. [Background technology]

[0002] There is known a toilet device that uses a pump to pressurize flush water stored in a tank to perform a jet flush (see, for example, Patent Document 1). In such a toilet device, the overflow pipe of the tank is connected to the jet flush flow path, and when flush water overflows from the tank, the water is discharged into the toilet bowl from the jet spout.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0008] As shown in Figure 1, the toilet device 1 according to this embodiment has a toilet body 2, a toilet seat (not shown), a functional unit 3, and a functional unit cover (not shown). In the following description, the front side is the side in front of a user seated on the toilet seat, the rear side is the side opposite to the front side, and the horizontal direction connecting these is the front-to-rear direction (the direction of arrow A in the drawing). The horizontal direction perpendicular to the front-to-rear direction is the width direction (the direction of arrow B in the drawing).

[0009] Figure 2 shows the toilet bowl 21 of the toilet body 2, with the peripheral wall 26 of the toilet body 2 (see Figure 1) that is provided around the toilet bowl 21 omitted. The toilet bowl 21 is located in the front part of the toilet body 2. The toilet bowl 21 has a water collection section 22 located at the bottom for collecting flushing water, and a rim 23 located on the periphery of the upper part. The toilet bowl 21 is formed with a jet water outlet 24 that discharges flushing water into the water in the water collection section 22 during flushing, and a rim water outlet 25 that discharges flushing water from above the water collection section 22 onto the rim 23 into the toilet bowl 21 during flushing.

[0010] As shown in Figures 2 to 4, the functional part 3 has various functions such as water supply, water storage, and flushing. The functional part 3 is arranged below the toilet bowl 21 and behind the toilet bowl 21. The lower side 31 of the functional part 3 is arranged inside the peripheral wall of the toilet body 2, and the upper side 32 protrudes above the toilet body 2. The part of the upper side 32 of the functional part 3 that protrudes above the toilet body 2 is arranged behind the toilet bowl 21. The functional part cover is arranged on top of the toilet body 2 and covers the part of the upper side 32 of the functional part 3 that protrudes above the toilet body 2.

[0011] Functional unit 3 has a flush water tank 34 (tank), a pump (water supply unit) 35 (see Figures 3 and 4), and a flushing mechanism 36. Functional unit 3 has functions other than those described above. Flush water tank 34 has a front portion 341 located below toilet bowl 21 (between toilet bowl 21 and the floor), and a rear portion 342 located behind toilet bowl 21. Front portion 341 and rear portion 342 are integrated. Rear portion 342 is taller than front portion 341 and protrudes above toilet bowl 21. Flush water tank 34 is supplied with water from a water supply pipe (not shown). Pump 35 pressure-feeds flush water from flush water tank 34 to flushing mechanism 36.

[0012] As shown in Figure 5, a rim-side overflow channel 343 and a jet-side overflow channel 344, through which overflow water from the flush water tank 34 flows, are connected to the rear section 342 of the flush water tank 34. The rim-side overflow channel 343 is connected to the rim spout 25 (see Figure 2). The overflow water that flows through the rim-side overflow channel 343 is discharged from the rim spout 25 into the interior of the toilet bowl 21. The jet-side overflow channel 344 is connected to the jet spout 24 (see Figure 2). The overflow water that flows through the jet-side overflow channel 344 is discharged from the jet spout 24 into the water in the reservoir 22 of the toilet bowl 21. Overflow water from the flush water tank 34 refers to flush water that overflows from the flush water tank 34 because it cannot pass through the pump due to a malfunction of the pump, the water supply to the flush water tank 34, or the flushing mechanism, etc.

[0013] The rim-side overflow flow path 343 and the jet-side overflow flow path 344 are located at separate positions. In this embodiment, the rim-side overflow flow path 343 and the jet-side overflow flow path 344 are located at separate positions in the width direction. The rim-side overflow flow path 343 is connected to the upper part of one side in the width direction of the rear part 342 of the flush water tank 34, and the jet-side overflow flow path 344 is connected to the upper part of the other side in the width direction of the rear part 342 of the flush water tank 34. The rim-side overflow flow path 343 extends upward from the flush water tank 34, extends from there to the other side in the width direction, and then extends downward to be connected to the rim flush flow path 43 of the flushing mechanism, which is connected to the rim water outlet 25. The jet-side overflow flow path 344 extends upward from the flush water tank 34, extends from there to one side in the width direction, and then extends downward to be connected to the jet flush flow path 42 of the flushing mechanism, which is connected to the jet water outlet 24. The upper side of the jet-side overflow flow path 344 is located inside the vacuum breaker case 6.

[0014] The upper end 343a of the rim-side overflow flow path 343 is located lower than the upper end 344a of the jet-side overflow flow path 344. Flush water pumped under pressure flows through both the rim flush flow path 43 and the jet flush flow path 42. Flush water flows through the rim flush flow path 43 when a rim flush is performed in which water is spouted from the rim water spouting port 25. Flush water flows through the jet flush flow path 42 when a jet flush is performed in which water is spouted from the jet water spouting port 24.

[0015] The discharge flow rate of flush water is adjusted by adjusting the rotation speed of pump 35. When the rotation speed of pump 35 is increased, the discharge flow rate of flush water also increases. When the rotation speed of pump 35 is decreased, the discharge flow rate of flush water also decreases. As the rotation speed of pump 35 increases and the discharge flow rate of flush water increases, the water pressure of the flush water pressure-fed from pump 35 also increases. As the rotation speed of pump 35 decreases and the discharge flow rate decreases, the water pressure of the flush water pressure-fed from pump 35 also decreases.

[0016] The cleaning mechanism 36 has a pump connection flow path 41, a jet cleaning flow path 42 (see FIG. 3), a rim cleaning flow path 43 (see FIG. 4), and a switching mechanism 5. The pump connection flow path 41 is connected to the pump 35, and cleaning water pumped by the pump 35 flows into it. The switching mechanism 5 has a switching valve 51 connected downstream of the pump connection flow path 41, and a control unit 56 (see FIG. 3). The control unit 56 adjusts the amount of cleaning water supplied from the pump 35 to the switching valve 51 by adjusting the rotation speed of the pump 35 (pump rotation speed). In FIG. 3, the control unit 56 is shown by a dashed line. The control unit 56 may be provided in a desired position. The jet cleaning flow path 42 and the rim cleaning flow path 43 are connected downstream of the switching valve 51. The switching valve 51 is configured to be able to switch between jet flush and rim flush by switching the flow path through which flush water from the pump connection flow path 41 flows to either the jet flush flow path 42 or the rim flush flow path 43, or both, depending on the amount of flush water supplied from the pump 35. The flush water flowing through the jet flush flow path 42 is discharged into the water collection section 22 from the jet water spouting port 24 shown in Figure 2. The flush water flowing through the rim flush flow path 43 is discharged onto the rim 23 from the rim water spouting port 25 shown in Figure 2. Below, the discharge of flush water from the jet water spouting port 24 will sometimes be referred to as jet flush, and the discharge of flush water from the rim water spouting port 25 will sometimes be referred to as rim flush.

[0017] As shown in Figure 6, the switching valve 51 has an inflow section 52 into which flush water flows from the pump connection flow path 41 (see Figures 3 and 4), a jet water passage section 53 connected downstream of the inflow section 52 and allowing the flush water to flow into the jet wash flow path 42 (see Figure 3), and a rim water passage section 54 connected downstream of the inflow section 52 and allowing the flush water to flow into the rim wash flow path 43 (see Figure 4). The jet water passage section 53 and the rim water passage section 54 are each directly connected to the inflow section 52. Flushing water flows directly into the jet water passage section 53 and the rim water passage section 54 from the inflow section 52.

[0018] As shown in Figure 7, the jet water passage 53 has a jet water spouting flow rate adjustment valve 531 and an overflow inlet 55. The jet water spouting flow rate adjustment valve 531 is configured to open and close the jet water passage 53 and adjust the amount of flushing water passing through the jet water passage 53, thereby adjusting the water spouting flow rate of jet washing. The jet water spouting flow rate adjustment valve 531 is provided at the upstream end of the jet water passage 53. The overflow inlet 55 is connected to the jet side overflow flow path 344 and is configured so that overflow water that has flowed through the jet side overflow flow path 344 flows into it. The overflow inlet 55 is provided downstream of the jet water spouting flow rate adjustment valve 531. The overflow inlet 55 is provided with a check valve 551 and is configured so that flushing water that has passed through the jet water spouting flow rate adjustment valve 531 does not flow in during jet washing.

[0019] The jet water spouting flow rate adjustment valve 531 has a first valve body 532, a first valve seat 533, and a first spring member 534. The first valve body 532 is provided on the downstream side of the first valve seat 533, and is pushed by the first spring member 534 in a direction approaching the first valve seat 533 (towards the upstream side). The jet water spouting flow rate adjustment valve 531 operates in a normal state when flush water does not flow into the inflow section 52 and in a normal state when flush water flows into the inflow section 52. to When the water pressure of the inflowing flush water is lower than a predetermined water pressure, first valve body 532 comes into contact with first valve seat 533 and closes the flow path of jet water passage section 53 (closed state). In other words, jet water spouting flow rate adjustment valve 531 closes the flow path of jet water passage section 53 when the amount of flush water flowing into inflow section 52 is lower than a predetermined amount.

[0020] As shown in Figure 8, when the water pressure of flush water flowing into inlet portion 52 exceeds a predetermined water pressure, first valve body 532 is pushed downstream by the water pressure of the flush water. This causes first spring member 534 to elastically deform, and first valve body 532 moves downstream and separates from the valve seat. A gap is created between first valve body 532 and first valve seat 533 in jet water spouting flow rate adjustment valve 531, and jet water passage portion 53 opens its flow path (open state). In other words, when the amount of flush water flowing into inlet portion 52 is equal to or greater than a predetermined amount, jet water spouting flow rate adjustment valve 531 opens the flow path of jet water passage portion 53.

[0021] When the flush water discharge flow rate of jet water spouting flow adjustment valve 531 is increased from a closed state to increase the water pressure, the flush water water pressure at which first valve body 532 of jet water spouting flow adjustment valve 531 separates from first valve seat 533 to an open state is referred to as the "jet opening water pressure." When the flush water water pressure reaches the jet opening water pressure, the opening between first valve body 532 and first valve seat 533 of jet water spouting flow adjustment valve 531 gradually increases, and the valve enters an open state. When the flush water discharge flow rate is reduced to reduce the water pressure from the jet opening water pressure, the opening between first valve body 532 and first valve seat 533 gradually decreases, and the valve enters a closed state.

[0022] The jet water passage section 53 has a rectifying section 535 downstream of the jet water spouting flow rate adjustment valve 531. The rectifying section 535 is connected to the downstream side of the valve seat. The rectifying section 535 has, for example, a cross shape formed by plates extending in the direction the flush water flows. The rectifying section 535 is provided to ensure that the flush water that passes through the first valve body 532 and first valve body 532 of the jet water spouting flow rate adjustment valve 531 in the open state and is prone to turbulence flows uniformly towards the jet wash flow path 42.

[0023] As described above, the overflow inlet section 55 is provided downstream of the jet water spouting flow rate adjustment valve 531, and is configured so that during jet flushing, the check valve 551 prevents flush water that has passed through the jet water spouting flow rate adjustment valve 531 from flowing in. For this reason, when the jet water spouting flow rate adjustment valve 531 is closed (when jet flushing is not being performed), the overflow water from the flush water tank 34 that flows through the jet-side overflow flow path 344 and into the jet water passing section 53 from the overflow inlet section 55 flows into the jet flushing flow path 42 and can be spouted into the inside of the toilet bowl from the jet water spouting outlet 24. The rim-side overflow flow path 343 is connected to the jet flushing flow path 42 via the switching valve 51.

[0024] As shown in Figure 7, the rim water passage section 54 has a rim water discharge flow rate adjustment valve 541. The rim water discharge flow rate adjustment valve 541 is configured to open and close the rim water passage section 54, adjusting the amount of flush water passing through the rim water passage section 54 and thereby adjusting the water discharge flow rate of the rim flush. The rim water discharge flow rate adjustment valve 541 is provided at the upstream end of the rim water passage section 54. The rim water discharge flow rate adjustment valve 541 has a second valve body 542, a second valve seat 543 and a second spring member 544. The second valve body 542 is provided upstream of the second valve seat 543, and is pushed by the second spring member 544 in a direction away from the second valve seat 543 (towards the downstream side).

[0025] In normal times when no flush water flows into inlet section 52, and when the water pressure of flush water that has flowed into inlet section 52 is lower than a predetermined water pressure, rim water discharge flow rate adjustment valve 541 moves second valve body 542 away from second valve seat 543, opening the flow path of rim water passage section 54 (open state). In other words, rim water discharge flow rate adjustment valve 541 opens the flow path of rim water passage section 54 when the amount of flush water flowing into inlet section 52 is lower than a predetermined amount.

[0026] As shown in Figure 8, when the water pressure of flush water flowing into inlet portion 52 exceeds a predetermined water pressure, second valve body 542 is pushed downstream by the water pressure of the flush water. This causes second spring member 544 to elastically deform, and second valve body 542 moves downstream and comes into contact with the valve seat. The rim water discharge flow rate adjustment valve 541 closes the gap between second valve body 542 and second valve seat 543, and closes the flow path of rim water passage portion 54 (closed state). In other words, rim water discharge flow rate adjustment valve 541 closes the flow path when the amount of flush water flowing into inlet portion 52 is equal to or greater than a predetermined amount.

[0027] When the flush water discharge flow rate of rim water discharge flow adjustment valve 541 is increased from an open state to increase the water pressure, second valve body 542 of rim water discharge flow adjustment valve 541 moves toward second valve seat 543 (downstream), and the flush water pressure at which second valve body 542 comes into contact with second valve seat 543 and enters a closed state is called the "rim closing pressure." When the flush water pressure reaches the rim closing pressure, the opening between second valve body 542 and second valve seat 543 of rim water discharge flow adjustment valve 541 gradually becomes smaller, and the valve enters a closed state. When the discharge flow rate is reduced and the flush water pressure decreases from the rim closing pressure, the gap between second valve body 542 and second valve seat 543 gradually becomes larger, and the valve enters an open state.

[0028] The jet opening water pressure is set lower than the rim closing water pressure. As a result, when the rim water passage 54 is opened and the jet water passage 53 is closed and the flush water discharge flow rate is increased to increase the water pressure, the jet opening water pressure is reached and the jet water passage 53 is opened, and then the rim closing water pressure is reached and the rim water discharge flow rate adjustment valve 541 is closed. In other words, when switching between rim flush and jet flush, as shown in Figure 8, the flow paths of both the jet water passage 53 and the rim water passage 54 are open. For this reason, the flow paths for both the jet flush and rim flush are not closed and the flush water flow path is not blocked, and the flush water flow path is not suddenly switched, so switching between rim flush and jet flush can be done smoothly.

[0029] The water pressure of the flush water when only rim flush is performed is called the rim flush water pressure. The rim flush water pressure is set lower than the jet opening water pressure. The water pressure of the flush water when only jet flush is performed is called the jet flush water pressure. The jet flush water pressure is set higher than the rim closing water pressure. The rotation speed of the pump 35 at which the water pressure of the flush water becomes the rim flush water pressure is called the rim flush rotation speed. The rotation speed of the pump 35 at which the water pressure of the flush water becomes the jet flush water pressure is called the jet flush rotation speed. In this embodiment, the water pressure increases in the order of rim flush water pressure, jet opening water pressure, rim closing water pressure, and jet flush water pressure. By setting the rim flush water pressure, jet opening water pressure, rim closing water pressure, and jet flush water pressure, respectively, the jet water spouting flow rate adjustment valve 531 and the rim water spouting flow rate adjustment valve 541 can be controlled independently.

[0030] The control unit 56 (see Figure 3) adjusts the rotation speed (pump rotation speed) of the pump 35 to adjust the water pressure of the cleaning water supplied from the pump 35 to the switching valve 51, thereby controlling whether the cleaning water flows through the jet water passage section 53 or the rim water passage section 54, and adjusting the water flow rate for the rim cleaning and the water flow rate for the jet cleaning.

[0031] As shown in Figure 10, when the control unit 56 receives a flush start signal, it increases the pump rotation speed from 0 to the rim flush rotation speed. As the pump rotation speed increases, the flush water discharge flow rate also increases. When the pump rotation speed reaches the rim flush rotation speed, the flush water pressure becomes rim flush water pressure and a rim flush (first rim flush) is performed. Even while the pump rotation speed is greater than 0 and reaches the rim flush rotation speed, the rim water discharge flow rate adjustment valve 541 remains open, as shown in Figure 7, so a rim flush is performed. The flush water discharge flow rate can be adjusted by adjusting the pump rotation speed between 0 and the rim flush rotation speed.

[0032] As shown in Figure 10, once a predetermined time has elapsed in the first rim flush, the control unit 56 further increases the pump rotation speed to the jet flush rotation speed. When the pump rotation speed increases and the water pressure of the flush water reaches the jet opening water pressure, the jet water spouting flow rate adjustment valve 531 opens while the rim water spouting flow rate adjustment valve 541 remains open, as shown in Figure 9, and both rim flush and jet flush are performed. The range in which both rim flush and jet flush are performed is the range indicated by symbol C in Figure 10. As shown in Figure 10, once the pump rotation speed increases and the water pressure of the flush water reaches the rim closing water pressure, the rim water spouting flow rate adjustment valve 541 closes and only jet flush is performed. When the pump rotation speed reaches the jet flush rotation speed and the water pressure of the flush water reaches the jet flush water pressure, only jet flush continues to be performed. When the pump rotation speed reaches the jet flush rotation speed, the rim water spouting flow rate adjustment valve 541 is completely closed. The flow rate of flush water can be adjusted by adjusting the pump rotation speed between the rim flush rotation speed and the jet flush rotation speed.

[0033] 9, when the pump rotation speed is reduced and the water pressure becomes lower than the rim closing pressure, the rim water spouting flow rate adjustment valve 541 is opened while the jet water spouting flow rate adjustment valve 531 remains open, and both jet and rim flushes are performed. The range in which both rim and jet flushes are performed is the range indicated by symbol D in FIG. 9. As shown in FIG. 9, when the pump rotation speed is reduced and the water pressure becomes lower than the jet opening pressure, the jet water spouting flow rate adjustment valve 531 is closed and only rim flush is performed. When the pump rotation speed reaches the rim flush rotation speed, the rim flush (second rim flush) continues. When the pump rotation speed reaches the rim flush rotation speed, the jet water spouting flow rate adjustment valve 531 is completely closed. The flush water spouting flow rate can be adjusted by adjusting the pump rotation speed between the jet flush rotation speed and the rim flush rotation speed. When the second rim flush has been performed for a predetermined time, the control unit 56 reduces the pump rotation speed to 0. As the pump rotation speed decreases, the amount of flush water pumped from the pump 35 decreases and the water pressure of the flush water also decreases. When the pump rotation speed reaches 0, the rim flush stops.

[0034] The upper end 343a of the rim-side overflow channel 343 is located lower than the upper end 344a of the jet-side overflow channel 344. Due to the difference in height between the upper end 343a of the rim-side overflow channel 343 and the upper end 344a of the jet-side overflow channel 344, the overflow water of the flush water tank 34 passes through the upper end 343a of the rim-side overflow channel 343 earlier than the upper end 344a of the jet-side overflow channel 344. For this reason, the overflow water of the flush water tank 34 can be spouted from the rim spouting port 25 before the jet spouting port 24, and when water is spouted from the jet spouting port 24, it will also be spouted from the rim spouting port 25.

[0035] When overflow water is discharged from the rim spout 25, it flows along the rim, and when it is discharged from the jet spout 24, it is discharged into the flush water that has accumulated in the water reservoir 22. For this reason, overflow water is more easily noticeable by the user when it is discharged from the rim spout 25 than when it is discharged from the jet spout 24. As described above, the toilet apparatus 1 is able to cause overflow water from the flush water tank 34 to be discharged from the rim spout 25 before it is discharged from the jet spout 24, and when water is discharged from the jet spout 24, it will also be discharged from the rim spout 25. As a result, when an overflow occurs in the flush water tank 34, water will be discharged from the rim spout 25 regardless of the volume of overflow water, even if the flow rate is low, making it easy for the user to notice an overflow in the flush water tank 34.

[0036] In the toilet apparatus 1 according to the above embodiment, the rim-side overflow flow path 343 is connected to the switching valve 51, and is connected to the jet flush flow path 42 via the switching valve 51. This allows the overflow water from the flush water tank 34 to be discharged into the toilet bowl 21 using a flushing mechanism that switches between jet flushing and rim flushing. Therefore, compared to when the rim-side overflow flow path 343 is directly connected to the rim spout 25, the length of the flow path can be shortened, resulting in a simpler structure, which allows for size reduction and cost reduction.

[0037] The present disclosure is not limited to the above-described embodiment, and can be modified as appropriate without departing from the spirit thereof. For example, in the above-described embodiment, overflow water from the flush water tank 34 is first discharged from the rim spout 25, and then from the jet spout 24. Alternatively, overflow water from the flush water tank 34 may be discharged only from the rim spout 25.

[0038] In the above embodiment, the upper end 343a of the rim-side overflow channel 343 is located lower than the upper end 344a of the jet-side overflow channel 344. However, the positional relationship between the upper end 343a of the rim-side overflow channel 343 and the upper end 344a of the jet-side overflow channel 344 may be other than that described above. It is also possible to use head pressure to have overflow water from the flush water tank 34 first spouted from the rim spouting outlet 25, and then spouted from the jet spouting outlet 24.

[0039] In the above embodiment, the jet side overflow flow path 344 is connected to the switching valve 51. In contrast to this, the jet side overflow flow path 344 may be connected directly to the jet water spout 24 without being connected to the switching valve 51. Instead of the jet side overflow flow path 344, the rim side overflow flow path 343 may be connected to the rim water passage part 54 of the switching valve 51, and the overflow water that has flowed through the rim side overflow flow path 343 may be connected to the rim water spout 25 via the switching valve 51.

[0040] In the above embodiment, the jet opening water pressure is set lower than the rim closing water pressure. Alternatively, the jet opening water pressure may be set higher than the rim closing water pressure. As a result, when the flush water discharge flow rate is increased to raise the water pressure from a state in which the rim water passage section 54 is open and the jet water passage section 53 is closed, the rim closing water pressure is reached and the rim water discharge flow rate adjustment valve 541 is closed before the jet opening water pressure is reached and the jet water passage section 53 is opened. In other words, when switching between rim flush and jet flush, the flow paths of both the jet water passage section 53 and the rim water passage section 54 are closed. As a result, jet flush and rim flush can be performed independently, and the flush water discharge flow rate can be reduced. [Explanation of symbols]
