Description

  The present invention relates to a pressure accumulator, and a flush toilet, an elevating device, and a soap dispenser including the same, and in particular, a pressure accumulator that stores pressurized tap water in a pressure accumulator connected to a water supply pipe, And a flush toilet, an elevating device, and a soap dispenser including the same.

In recent years, flush toilets directly connected to water supply have become widespread. This flush toilet flush toilet does not require a flush tank to store flush water, so the overall flush toilet can be kept low, and the floor area occupied by the flush toilet can be reduced. Since it can be made smaller, it is widely adopted.
However, in the flush toilets directly connected to the water supply, the wash water is discharged from the rim spout and jet nozzle by the tap water pressure, so the washing power is reduced in areas where the tap water pressure is low, so it cannot be adopted. There is.

  Japanese Patent Laid-Open No. 10-159150 (Cited Document 1) describes a pressure-accumulating drainage device for a flush toilet. In this pressure-accumulation drainage system, in order to increase the cleaning power, the flush toilet wash water is accumulated and stored up to the tap water pressure, and when flushing, the toilet is washed using the accumulated pressure. Yes.

JP 10-159150 A

  However, in the pressure-accumulation drainage device described in Japanese Patent Application Laid-Open No. 10-159150, the maximum accumulated pressure can be increased only to the tap water pressure in principle, so that the cleaning ability cannot be sufficiently increased. There's a problem. For example, the ability to inject wash water from a jet nozzle and induce a siphon phenomenon in a flush toilet is generally proportional to the energy stored by pressurization. Here, when the washing water of volume V is pressurized and stored up to the pressure P, the accumulated energy E becomes equal to ∫PdV. Therefore, in order to accumulate a large amount of energy with a low pressure accumulation pressure, it is necessary to increase the amount of stored wash water. However, in order to increase the washing capacity of flush toilets even in areas where tap water pressure is low, storing a large amount of pressurized water increases the overall size of the flush toilet including the container for storing pressurized water. There is a problem that the merit of the flush toilet cannot be fully exhibited.

  Strictly speaking, the tap water pressure is slightly lower when water is discharged than when the water is stopped. In this specification, the tap water pressure means the water pressure when the water is stopped.

Therefore, an object of the present invention is to provide a pressure accumulating device that stores pressurized tap water in a pressure accumulating container connected to a water supply pipe.
Another object of the present invention is to provide a flush toilet provided with a pressure accumulating device for storing wash water pressurized to a pressure higher than the tap water pressure in a pressure accumulating container connected to a water supply pipe. .

When the pressurized tap water flows into the pressure accumulating container, the energy is stored in the energy storage means. On the other hand, when the on-off valve is opened, the water pressure in the vicinity of the end on the inlet side decreases, but since the check valve is arranged, the backflow of tap water in the pressure accumulating vessel is prevented. By repeating this opening and closing, the pressure of tap water in the pressure accumulating vessel rises.

Next, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
First, referring to FIGS. 1 to 3, a flush toilet according to a first embodiment of the present invention will be described. FIG. 1 is a schematic cross-sectional view of a flush toilet according to a first embodiment of the present invention. Moreover, FIG. 2 is the block diagram which extracted and illustrated the part of the pressure accumulator built in the flush toilet of this embodiment. Furthermore, FIG. 3 is a schematic sectional view of a direct acting solenoid type electromagnetic valve used in the pressure accumulator.

  As shown in FIGS. 1 and 2, the flush toilet 1 according to the first embodiment of the present invention includes a ball portion 2, a trap portion 4 that communicates a bottom portion of the ball portion and a drain pipe (not shown), It has the jet nozzle 6 arrange | positioned at the bottom part of the ball | bowl part 2, and the pressure accumulator 10 which pressurizes the wash water supplied to this jet nozzle 6. FIG. The flush toilet 1 of the present embodiment stores the wash water pressurized to a tap water pressure or higher in the pressure accumulator 10, and jets the wash water pressurized when the ball part 2 is washed from the jet nozzle 6 to trap part 4. It is designed to induce a siphon phenomenon.

Moreover, the pressure accumulator 10 built in the flush toilet 1 according to the first embodiment of the present invention pressurizes the pressure accumulating container 12 for storing pressurized washing water and the washing water in the pressure accumulating container 12. And a pneumatic balloon 14 which is an energy storage means for storing energy. Further, the pressure accumulating device 10 includes a check valve 16 provided on the inlet side of the pressure accumulating vessel 12 and an open / close valve 18 connected to a branch pipe branched from a pipe line extending from the water supply pipe 8 to the check valve 16. And a water discharge valve 20 for injecting pressurized wash water in the pressure accumulating vessel 12 from the jet nozzle 6.
The flush toilet 1 includes a controller 22 that switches between rim water discharge cleaning and jet nozzle cleaning and controls the on-off valve 18 and the water discharge valve 20.

The ball portion 2 is configured so as to receive an filth by opening upward. Further, a rim portion 2a is formed around the upper portion of the ball portion 2, and cleaning water discharged from a rim water spouting port (not shown) flows downward while turning through the rim portion 2a. The wall surface is configured to be cleaned.
The trap part 4 is formed so as to extend obliquely upward from the bottom part of the ball part 2 and to extend vertically downward via the highest point 4a. The outlet end of the trap unit 4 is connected to a drain pipe (not shown) via a drain socket (not shown) or the like.

The jet nozzle 6 is disposed at the bottom of the ball part 2 and is directed so as to inject cleaning water in parallel with the pipe line on the inlet side of the trap part 4. The jet nozzle 6 is supplied with wash water pressurized to a tap water pressure or higher by the pressure accumulator 10 and jets high-pressure wash water.
Switching of the water discharged from the rim water spouting port (not shown) and the jet nozzle 6 at the time of cleaning the ball unit 2 is performed by a toilet flushing valve unit (not shown) and a controller 22 that controls the toilet bowl cleaning valve unit. The toilet flushing valve unit (not shown) is configured to direct flushing water supplied from the water supply to the rim water spouting port or the pressure accumulator 10 by switching the valves. Wash water guided to the pressure accumulator 10 by a toilet flush valve unit (not shown) is supplied to the pressure accumulator 10 through the water supply pipe 8. Moreover, the wash water discharged from the rim water spouting port (not shown) is directly supplied from a toilet cleaning valve unit (not shown) through a pipe line (not shown) extending to the rim water spouting port.

  The pressure accumulating container 12 of the pressure accumulating device 10 is disposed inside the flush toilet 1 and below the ball portion 2 and the trap portion 4. Inside the pressure accumulating container 12, a pneumatic balloon 14 serving as energy storage means is disposed. The balloon 14 is configured such that when the cleaning water in the pressure accumulating container 12 is pressurized, the air in the balloon 14 is compressed and the volume is reduced. The energy obtained by compressing the air in the balloon 14 is accumulated as energy for jetting high-pressure washing water during washing. In addition, arbitrary fluids, such as inert gas, such as nitrogen and helium, can be used as a fluid enclosed with a balloon.

  The check valve 16 is disposed on the inlet side of the pressure accumulating container 12 so that the cleaning water in the pressure accumulating container 12 does not flow back to the water supply pipe 8 side through the inlet of the pressure accumulating container 12. For this reason, when the pressure on the water supply pipe 8 side is higher than that in the pressure accumulating vessel 12, the wash water flows into the pressure accumulating vessel 12 from the water supply pipe 8, but the pressure in the pressure accumulating vessel 12 is greater than that on the water supply pipe 8 side. Is higher, the washing water does not flow backward from the pressure accumulating vessel 12 to the water supply pipe 8 side.

  The on-off valve 18 is connected to a branch line 18 a branched from a pipe line extending from the water supply pipe 8 to the check valve 16. The on-off valve 18 includes an inlet-side end portion 18b and an outlet-side end portion 18c, and is configured to repeatedly open and close at high speed. Further, the outlet side end portion 18c is connected to a rim water spouting port (not shown) by a drain pipe 18d. When the on-off valve 18 is opened, the wash water supplied from the water supply pipe flows out from the inlet side end 18b to the outlet side end 18c. The washing water that has flowed out from the outlet side end 18c is discharged from a rim water spouting port (not shown) through the drain pipe 18d.

  Further, when the on-off valve 18 is closed, the water hammer phenomenon occurs because the flow of the cleaning water supplied from the water supply pipe from the inlet side end 18b to the outlet side end 18c is suddenly blocked. The water pressure in the vicinity of the inlet side end portion 18b is configured to increase. In the present embodiment, a direct acting solenoid type solenoid valve is used as the on-off valve 18 and is repeatedly opened and closed about 50 times per second. Opening and closing of the on-off valve 18 is controlled by the controller 22.

  The water discharge valve 20 is disposed on the outlet side of the pressure accumulation container 12. Further, the downstream side of the water discharge valve 20 is connected to the jet nozzle 6. Opening and closing of the water discharge valve 20 is controlled by the controller 22, and is configured such that pressurized wash water in the pressure accumulating container 12 is ejected from the jet nozzle 6 when opened.

  The controller 22 includes a CPU, a memory, and the like, and is configured to execute a predetermined toilet flushing sequence by controlling a toilet flushing valve unit (not shown), the on-off valve 18, the water discharge valve 20, and the like.

  Next, with reference to FIG. 3, the direct acting solenoid type electromagnetic valve used as the on-off valve 18 in the flush toilet 1 of this embodiment is demonstrated. As shown in FIG. 3, the on-off valve 18 includes a valve seat 24 formed at the inlet end 18b, a valve body 26 that reciprocates linearly so as to open and close the valve seat 24, and the valve body 26. It has a drive coil 28 that is an actuator that drives to the closing side, and a biasing spring 30 that biases the valve body 26 to the opening side.

The valve seat 24 has a circular opening, and is configured to be closed when the valve body 26 is seated and opened when the valve body 26 is separated.
The valve body 26 is configured to be driven by a driving coil 28 in a direction (vertical direction in FIG. 3) orthogonal to the opening surface of the valve seat 24 (horizontal surface in FIG. 3).

The driving coil 28 is disposed so as to surround a part of the valve body 26. When a current flows through the driving coil 28, a driving force is applied to the valve body 26 that is at least partially formed of a magnetic material, and the valve body 26 is seated on the valve seat 24 (vertically below in FIG. 3). Driven.
The urging spring 30 has one end attached to the valve body 26 and the other end attached to the drive coil 28, and urges the valve body 26 in a direction (vertically upward in FIG. 3) to be separated from the valve seat 24. For this reason, when the current flowing through the drive coil 28 is stopped, the valve element 26 is separated from the valve seat 24 by the biasing force of the biasing spring 30.
With this configuration, the on-off valve 18 repeats opening and closing by intermittently turning on / off the current flowing through the driving coil 28.

  In the present embodiment, the on-off valve 18 is closed by the current flowing in the driving coil 28. Therefore, the on-off valve 18 is abruptly closed by increasing the driving force generated by the driving coil 28. Pressurization due to the water hammer phenomenon can be strengthened. On the other hand, since the urging force by the urging spring 30 is used to open the on-off valve 18, a large urging force is not necessary, and the spring can be formed with a thin wire, so the urging spring 30 is designed to be small. be able to. For this reason, it becomes possible to comprise the on-off valve 18 whole in a small size.

Next, the operation of the flush toilet 1 according to the first embodiment of the present invention will be described.
First, during standby, the ball portion 2 of the flush toilet 1 is filled with sealed water up to the height of the highest point 4 a of the trap portion 4. The balloon 14 in the pressure accumulating container 12 is in a compressed state, and a predetermined amount of washing water pressurized to a predetermined pressure is stored in the pressure accumulating container 12. When the user operates a washing switch (not shown) of the flush toilet 1, the controller 22 starts a predetermined toilet flushing sequence.

  First, the controller 22 sends a signal to a toilet flushing valve unit (not shown), and switches the toilet flushing valve unit so that flushing water supplied from the water supply is discharged from a rim spout (not shown). The cleaning water discharged from the rim water spouting port (not shown) cleans the wall surface of the ball part 2 while turning and raises the water level in the ball part 2.

  After the rim water discharge is performed for a predetermined time, the controller 22 stops water discharge from a rim water discharge port (not shown) and sends a signal to the water discharge valve 20 to open the water discharge valve 20. When the water discharge valve 20 is opened, the balloon 14 of the pressure accumulating container 12 is expanded by releasing the accumulated energy, and the washing water in the pressure accumulating container 12 is ejected from the jet nozzle 6 through the water discharge valve 20. The cleaning water ejected from the jet nozzle 6 flows into the trap unit 4 while entraining the cleaning water accumulated at the bottom of the ball unit 2 to fill the trap unit 4 with water. When the inside of the trap part 4 is filled with water, the inside of the trap part 4 becomes negative pressure due to the siphon phenomenon, and the cleaning water of the ball part 2 is sucked. Thereby, the filth and cleaning water in the ball part 2 are discharged through the trap part 4 to a drain pipe (not shown).

  In the flush toilet 1 of the present embodiment, since the pressurized wash water stored in the pressure accumulating container 12 is jetted from the jet nozzle 6, the wash water is ejected from the jet nozzle 6 by tap water pressure. Siphoning is induced by a jet of wash water much less than the toilet bowl. In the flush toilet 1 of the present embodiment, wash water pressurized to about 0.5 MPa is jetted from about 0.5 L (liter) jet nozzle 6.

  After water discharge from the jet nozzle 6 is performed for a predetermined time, the controller 22 closes the water discharge valve 20 and sends a signal to the open / close valve 18 to start opening / closing of the open / close valve 18. When the on-off valve 18 is opened, the wash water supplied from the water supply pipe 8 passes through the on-off valve 18 and is spouted into the ball unit 2 from the rim spout formed in the ball unit 2. Used as seal water. Further, when the on-off valve 18 is shut off, the water hammer phenomenon in which the washing water near the inlet end 18b of the on-off valve 18 is pressurized due to a rapid change in the speed of the washing water flowing through the on-off valve 18 is caused. The pressure near the inlet end 18b increases instantaneously. Due to this action, the water pressure upstream of the check valve 16 also rises, so that the wash water supplied from the water supply pipe 8 flows into the pressure accumulating vessel 12 through the check valve 16.

  The pressure of the cleaning water that rises instantaneously due to the water hammer phenomenon is much higher than the tap water pressure of the cleaning water supplied to the water supply pipe 8. For this reason, even after the washing water flows into the pressure accumulating vessel 12 and the pressure in the pressure accumulating vessel 12 reaches the tap water pressure, the washing water supplied from the water supply pipe 8 is pressurized by the water hammer phenomenon, and the check valve 16 flows into the pressure accumulating vessel 12. Further, at the moment when the on-off valve 18 is opened, the water pressure near the inlet side end 18b decreases, but the check valve 16 prevents the backflow of the washing water in the pressure accumulating vessel 12 and the high pressure in the pressure accumulating vessel 12 is reached. Is maintained. When the pressure in the pressure accumulating container 12 rises, the balloon 14 disposed in the pressure accumulating container 12 is compressed, and the volume of the balloon 14 is reduced. As a result, energy obtained by compressing the balloon 14 is accumulated in the balloon 14.

  When the pressure in the pressure accumulating container 12 rises to a predetermined pressure, the controller 22 stops the opening / closing of the on-off valve 18 and closes the on-off valve 18. Thereby, the pressure accumulation to the pressure accumulation container 12 is completed. Further, the controller 22 sends a signal to the toilet flushing valve unit (not shown) to discharge flush water from the toilet flushing valve unit directly to the rim spout (not shown). When the water level in the ball part 2 is raised to the water level in the standby state, one toilet cleaning sequence is completed.

According to the flush toilet of the first embodiment of the present invention, the high-pressure washing water can be stored in the pressure accumulating container by utilizing the water hammer phenomenon, which is generally considered to be undesirable.
Further, according to the flush toilet of the present embodiment, the wash water pressurized to a pressure higher than the tap water pressure is ejected from the jet nozzle, so that a siphon phenomenon can be generated in the trap portion with a small amount of wash water. . Thereby, it becomes possible to miniaturize the pressure accumulating container for storing the washing water, and the whole flush toilet can be miniaturized.

  Furthermore, according to the flush toilet of this embodiment, since the wash water pressurized to a pressure higher than the tap water pressure is ejected from the jet nozzle, a flush toilet with a direct water connection is installed in an area where the tap water pressure is low It becomes possible to do. Although the flush toilet of this embodiment supplies a part of the wash water from the pressure accumulator and supplies the rest directly from the water supply, the accumulator is very small and is a conventional tank-type flush toilet. Since the configuration is completely different from that of the first embodiment, here, the flush toilet including the flush toilet according to the present embodiment is referred to as a flush toilet with a direct connection to a water supply.

Next, with reference to FIG. 4, the 1st modification of the flush toilet by 1st Embodiment of this invention is demonstrated. FIG. 4 is a block diagram showing an extracted portion of the pressure accumulator built in the flush toilet of this modification.
In the present modification, the energy storage means that is configured by the balloon containing air in the first embodiment is configured by a piston and a spring disposed in the pressure accumulating container. As shown in FIG. 4, the piston 32 is slidably disposed in the pressure accumulation container 12. As the piston 32 slides in the pressure accumulating container 12, the internal volume of the pressure accumulating container 12 changes. Further, the spring 34 is disposed in the pressure accumulating container 12 so as to apply a biasing force to the piston 32. The piston 32 is urged by a spring 34 in the direction of reducing the internal volume of the pressure accumulating container 12. In this modification, when the cleaning water in the pressure accumulating container 12 is pressurized, the piston 32 slides against the urging force of the spring 34 and elastic energy is accumulated in the compressed spring 34. When the water discharge valve 20 is opened, the energy accumulated in the spring 34 is released, and pressurized washing water is jetted from the jet nozzle 6.

  According to the first modification configured as described above, the release rate of the elastic energy from the energy storage means can be adjusted by the spring constant of the spring 34. This also makes it possible to release energy slowly.

As a second modification, a compressible fluid such as air can be used as the energy storage means. In this case, air or the like confined in the pressure accumulating container 12 is compressed by pressurizing the washing water, and energy is accumulated.
According to the second modified example configured as described above, an energy storage unit can be realized without providing a special member. Moreover, according to this modification, the shape of the pressure accumulation container can be designed freely.

Next, with reference to FIG. 5, the 3rd modification of the flush toilet by 1st Embodiment of this invention is demonstrated. FIG. 5 is a block diagram showing an extracted portion of the pressure accumulator built in the flush toilet of the present modification.
In the third modified example shown in FIG. 5, an expandable portion 36 is provided to prevent the influence of the pressure generated by opening / closing the on-off valve 18 from affecting other devices connected to the water supply pipe 8. . When the on-off valve 18 repeats opening and closing, when a high pressure is generated in the vicinity of the inlet end 18 b of the on-off valve 18, the influence is propagated to the upstream side of the water supply pipe 8 in addition to the check valve 16. If the influence of this high pressure propagates to other equipment (not shown) connected to the upstream side of the water supply pipe 8, there is a possibility that the equipment will be adversely affected. In this modification, as shown in FIG. 5, an expandable portion 36 made of rubber is provided on the upstream side of the branch pipe 18a. When the internal pressure rises, the expandable portion 36 expands its internal volume, consumes energy of pressure propagating upstream of the branch pipe 18a, and lowers the internal pressure. When the expandable portion 36 expands and the internal pressure decreases, the influence of the high pressure generated by the on-off valve 18 is blocked by the expandable portion 36 and is connected to the other water supply pipe 8 on the upstream side of the expandable portion 36. Equipment is no longer affected. The expandable part 36 is preferably arranged at a predetermined distance from the branch pipe 18a. Preferably, the distance from the branch pipe 18a to the expandable part 36 is the distance from the branch pipe 18a to the check valve 16. It is preferable to arrange the expandable part 36 so as to be longer than the distance up to. By disposing the expandable portion 36 in this way, most of the pressure generated by the on-off valve 18 is absorbed by the expandable portion 36 and prevents pressurization to the pressure accumulating container 12 from being hindered. be able to. In this modified example, an elastically deformable rubber tube is used as the expandable portion 36. However, the expandable portion 36 can also be configured by other members such as a metal bellows.

Next, a fourth modification of the flush toilet according to the first embodiment of the present invention will be described with reference to FIG. FIG. 6 is a block diagram showing an extracted portion of the pressure accumulating device built in the flush toilet of this modification.
In the 4th modification shown in FIG. 6, the 2nd non-return valve for preventing the influence of the pressure which generate | occur | produced with the on-off valve 18 from affecting the other apparatus connected to the water supply pipe 8 is provided. As described above, when the on-off valve 18 generates a high pressure, the influence is propagated to the upstream side of the water supply pipe 8 in addition to the check valve 16. As shown by an imaginary line in FIG. 6, many water-circulating devices D connected to the water supply pipe 8 are provided with a check valve V such as a water heater. When such a device D is connected to a water supply pipe, when the on-off valve 18 generates a high pressure and the influence reaches the check valve V, the check valve V of the water heater D implements the present invention. There is a possibility that the tap water between the check valve V and the water heater D is pressurized by acting in the same manner as the check valve 16 constituting a part of the form.

  Therefore, in this modification, the second check valve 38 is disposed upstream of the branch pipe line 18 a to which the on-off valve 18 is connected, and the influence of the high pressure generated by the on-off valve 18 is caused by the upstream side of the water supply pipe 8. It does not reach the equipment. That is, since the backflow of tap water from the on / off valve 18 to the upstream side due to the high pressure generated by the on / off valve 18 is blocked by the second check valve 38, it is connected to the upstream side of the second check valve 38. The influence on the device D is blocked. According to this modification, it is possible to reliably prevent the flush toilet according to the first embodiment of the present invention from affecting other devices.

Next, a fifth modification of the flush toilet according to the first embodiment of the present invention will be described with reference to FIG. FIG. 7 is a block diagram showing an extracted portion of the pressure accumulator built in the flush toilet of the present modification.
In the fifth modification shown in FIG. 7, a flow path extension 40 for increasing the pressure generated by the on-off valve 18 is provided. As described above, in the flush toilet according to the first embodiment of the present invention, high-pressure washing water is stored in the pressure accumulating container 12 by utilizing the water hammer phenomenon. The pressure generated by the water hammer phenomenon can be increased. The water hammer phenomenon generates high pressure by rapidly changing the flow rate of flowing water. By providing the flow path extension 40 on the upstream side of the on-off valve 18, the inertia of the flowing tap water increases, and the pressure generated when it is blocked can be increased. In the present modification, the expandable portion 42 is provided on the upstream side of the flow path extension 40 so that the influence of the pressure generated by the on-off valve 18 does not reach the upstream side of the flow path extension 40. In this modification, as shown in FIG. 7, a pipe wound in a coil shape is used as the flow path extension 40, but an arbitrary shape that lengthens the upstream path of the on-off valve 18. A pipe line can be used as the flow path extension 40.

  According to this modification, the pressure of the wash water stored in the pressure accumulator can be further increased.

  As shown in FIG. 8, a switching valve 45 is connected to the flush toilet 44 of this modification on the downstream side of the water discharge valve 20. Jet nozzles 6 and 46 are connected to the other end of the switching valve 45, and the wash water that has passed through the water discharge valve 20 is guided to the jet nozzle 6 or the second jet nozzle 46 by the switching valve 45. The switching valve 45 is switched by a control signal sent from the controller 22. Further, in the present modification, the second jet nozzle 46 is formed to have an inner diameter larger than that of the jet nozzle 6, and the jet nozzle 6 has an inner diameter of about 3 mm and the second jet nozzle 46 of about 7 mm.

Next, the operation of the flush toilet 44 of this modification will be described.
The flush toilet 44 of the present modification is the same as that of the first embodiment until the first rim water discharge in the toilet flushing sequence executed by the controller 22. Next, the controller 22 stops water discharge from a rim water discharge port (not shown) and sends a signal to the switching valve 45 to switch the switching valve 45 to the jet nozzle 6. Furthermore, the controller 22 sends a signal to the water discharge valve 20 to open the water discharge valve 20. When the water discharge valve 20 is opened, the cleaning water in the pressure accumulating container 12 is ejected from the jet nozzle 6 through the water discharge valve 20 and the switching valve 45 by the energy accumulated in the balloon 14. Due to this injection, a siphon phenomenon occurs in the trap portion 4.

  When a predetermined time has elapsed after opening the water discharge valve 20 and all the energy accumulated in the balloon 14 has been released, the controller 22 sends a signal to the switching valve 45 to move the switching valve 45 to the second jet nozzle 46 side. Switch to. When the switching valve 45 is switched to the second jet nozzle 46 side, the wash water that has flowed from the water supply pipe 8 through the check valve 16 into the pressure accumulating vessel 12 passes through the water discharge valve 20 and the switching valve 45 to the second jet nozzle. It is ejected from 46. The washing water ejected from the second jet nozzle 46 discharges the suspended waste remaining after the jet nozzle 6 ejects from the trap portion 4. The injection from the second jet nozzle 46 is performed based on the supply water pressure from the water supply pipe 8, and the inner diameter of the second jet nozzle 46 is larger than that of the jet nozzle 6, so that the flow velocity is higher than that of the injection from the jet nozzle 6. It will be low. After performing injection from the second jet nozzle 46 for a predetermined time, the controller 22 closes the water discharge valve 20 and starts accumulating pressure in the pressure accumulating container 12. Subsequent cleaning sequences are the same as those in the first embodiment, and a description thereof will be omitted.

  According to the flush toilet 44 of this modification, a large amount of washing water can be jetted while the pressure accumulating container 12 is downsized.

  Next, a seventh modification of the flush toilet according to the first embodiment of the present invention will be described with reference to FIG. This modification is different from the first embodiment in that a branch adjustment valve is provided on the upstream side of the on-off valve, and a second jet nozzle to which cleaning water is supplied via the branch adjustment valve is provided. FIG. 9 is a side sectional view of the flush toilet of the present modification.

  As shown in FIG. 9, in the flush toilet 47 of this modification, a branch adjustment valve 48 is connected to the upstream side of the branch pipe 18 a, and the water supply pipe 8 is connected to the branch adjustment valve 48.

Fork. The branch adjustment valve 48 is controlled by a control signal sent from the controller 22. Furthermore, also in this modification, the jet nozzle 6 has an inner diameter of about 3 mm, and the second jet nozzle 49 has an inner diameter of about 7 mm.

Next, the operation of the flush toilet 47 of this modification will be described.
The flush toilet 47 of the present modification is the same as that of the first embodiment until the first rim water discharge in the toilet flushing sequence executed by the controller 22. Next, the controller 22 stops water discharge from a rim water discharge port (not shown) and sends a signal to the water discharge valve 20 to open the water discharge valve 20. When the water discharge valve 20 is opened, the cleaning water in the pressure accumulating container 12 is ejected from the jet nozzle 6 through the water discharge valve 20 by the energy accumulated in the balloon 14. Due to this injection, a siphon phenomenon occurs in the trap portion 4.

  When a predetermined time has elapsed after opening the water discharge valve 20 and all the energy accumulated in the balloon 14 has been released, the controller 22 sends a signal to the branch adjustment valve 48, causing the branch adjustment valve 48 to move to the second jet nozzle 49. Switch so that washing water also flows on the side. When the branch adjustment valve 48 is switched, the wash water supplied from the water supply pipe 8 is ejected from the second jet nozzle 49 through the branch adjustment valve 48. The washing water ejected from the second jet nozzle 49 discharges the suspended waste remaining after the jet nozzle 6 ejects from the trap portion 4. The injection from the second jet nozzle 49 is performed based on the supply water pressure from the water supply pipe 8, and the inner diameter of the second jet nozzle 49 is larger than that of the jet nozzle 6, so that the flow velocity is higher than that of the injection from the jet nozzle 6. It will be low. At the same time as discharging water from the second jet nozzle 49, the controller 22 closes the water discharge valve 20, and causes the wash water that has passed through the branch adjustment valve 48 to flow into the pressure accumulation container 12 to accumulate pressure in the pressure accumulation container 12. To start. After water discharge from the second jet nozzle 49 is performed for a predetermined time, the branch adjustment valve 48 is switched so that the wash water flows only to the pressure accumulating vessel 12 side to complete the pressure accumulation. Subsequent cleaning sequences are the same as those in the first embodiment, and a description thereof will be omitted.

  According to the flush toilet 47 of the present modified example, since pressure accumulation can be started simultaneously with the start of water discharge from the second jet nozzle, the time required to accumulate pressure up to a predetermined pressure can be shortened. Moreover, according to the flush toilet 47 of this modification, a large amount of washing water can be jetted while the pressure accumulating container 12 is downsized.

  The above-described first embodiment of the present invention and the modification thereof use the pressure accumulating device of the present invention for pressurizing the washing water sprayed from the jet nozzle of the flush toilet, It can be applied to any device that uses pressurized tap water, such as a high-pressure water washing device.

The check valve 54 and the on-off valve 56 correspond to the check valve 16 and the on-off valve 18 in the first embodiment, and similarly to these, the check valve 54 and the on-off valve 56 act so as to feed high-pressure tap water into the pressure accumulating vessel 52. Detailed explanation is omitted. The tap water that has passed through the opening / closing valve 56 is discharged from a rim spout (not shown) of a flush toilet equipped with a lift toilet seat 50 and used as flush water for the flush toilet.
The pressure release valve 58 is provided in a pipe line on the downstream side of the pressure accumulating container 52. When the pressure releasing valve 58 is opened, the tap water stored in the pressure accumulating container 52 is discharged, and the piston 60 is moved rightward in FIG.

First, when the flush toilet is in use, the toilet seat 64 is in a lowered state, that is, in a state of being in contact with the upper surface of the flush toilet. Next, when the user operates a switch (not shown) of the lift toilet seat 50 after using the flush toilet, the opening / closing valve 56 starts to open and closes the tap water pressurized to the tap water pressure or higher. It is fed into the pressure accumulating vessel 52 through the valve 54. When the pressurized tap water flows into the pressure accumulating container 52, the piston 60 is moved and the toilet seat 64 is raised via the link mechanism 62. This helps the user to get up from the toilet seat 64. When the toilet seat 64 is raised to a predetermined position and the user stands up, the pressure release valve 58 is opened. When the pressure release valve 58 is opened, the pressure in the pressure accumulating container 52 is released, the piston 60 moves, and the toilet seat 64 descends.

  According to the lifting / lowering toilet seat which is the lifting / lowering device of the second embodiment of the present invention, the tap water is pressurized to the tap water pressure or higher based on the tap water pressure, and the toilet seat can be raised by the force based on the pressure. Further, in the lifting toilet seat of the present embodiment, the pressure in the pressure accumulating container is pressurized higher than the tap water pressure, so a large force can be generated even with a piston with a small pressure receiving area, so the entire apparatus can be downsized. Can do.

Next, with reference to FIGS. 11 and 12, a bus lift which is a lifting device according to a third embodiment of the present invention will be described. In the bus lift according to the present embodiment, the force generated by the pressure accumulated in the pressure accumulating vessel is used for raising and lowering the seat surface of the bus lift installed in the bathtub. FIG. 11 is a front sectional view of the bus lift according to the present embodiment, and FIG. 12 is a side sectional view.
As shown in FIGS. 11 and 12, the bus lift 70 according to the third embodiment of the present invention includes a pressure accumulating container 72, a check valve 74 provided in a pipe line upstream of the pressure accumulating container 72, and the check valve. The on-off valve 76 connected to the branch pipe 76a branched from the pipe upstream from the valve 74 and the pressure release valve 78 provided on the pipe downstream of the pressure accumulating vessel 72 are provided. Furthermore, the bus lift 70 of the present embodiment has a seat surface 80 that is a lifting platform placed on the pressure accumulation container 72.

The pressure accumulating container 72 is composed of a deformable balloon and is disposed in the bathtub. The pressure accumulating container 72 is configured such that when pressurized tap water flows into the pressure accumulating container 72, the volume expands, and the seat surface 80 placed thereon is pushed upward in the bathtub.
The check valve 74 and the on-off valve 76 correspond to the check valve 16 and the on-off valve 18 in the first embodiment, and similarly to these, the check valve 74 and the on-off valve 76 act to send high-pressure tap water into the pressure accumulating vessel 72. Detailed explanation is omitted.
The pressure release valve 78 is provided in a pipe line on the downstream side of the pressure accumulating vessel 72, and is configured such that tap water in the pressure accumulating vessel 72 flows into the bathtub when opened.

It is rising. Next, when the user sits on the seat surface 80 of the bus lift 70 and operates a lowering switch (not shown) of the bus lift 70, the pressure release valve 78 is opened. When the pressure release valve 78 is opened, the tap water in the pressure accumulating container 72 is pushed out of the pressure accumulating container 72 by the weight of the user and flows into the bathtub. As the tap water in the pressure accumulating container 72 is discharged, the volume of the pressure accumulating container 72 is reduced, and the seating surface 80 placed thereon is gently lowered. In addition, since the volume of the pressure accumulation container 72 is sufficiently smaller than the bathtub, and the tap water in the pressure accumulation container 72 is warmed by the hot water in the bathtub, the tap water stored in the pressure accumulation container 72 flows in. The change in the temperature of the hot water in the bathtub is negligible.

  When raising the seating surface 80, the raising switch (not shown) of the bus lift 70 is operated. When a raising switch (not shown) is operated, the pressure release valve 78 is closed, and the opening / closing of the opening / closing valve 76 is started. By opening and closing the on-off valve 76, tap water pressurized to a tap water pressure or higher flows into the pressure accumulating vessel 72 through the check valve 74. As a result, the volume of the pressure accumulating container 72 expands and the seating surface 80 rises gently.

  According to the bus lift which is the lifting device of the third embodiment of the present invention, the tap water is pressurized to the tap water pressure or higher based on the tap water pressure, and the seating surface can be raised by the force based on this pressure. Further, in the bus lift of the present embodiment, the pressure in the pressure accumulating vessel is pressurized higher than the tap water pressure, so even if the pressure receiving area of the seat surface is small, a large force acts on the seat surface, so the entire device is It can be downsized.

  Next, with reference to FIG. 13, the soap dispenser by 4th Embodiment of this invention is demonstrated.

Furthermore, the soap dispenser 90 of this embodiment includes a detergent container 100 connected so as to communicate with the pressure accumulating container 92 and a detergent discharge valve 102 for discharging the detergent in the detergent container 100. In addition, the soap dispenser 90 is provided with a second check valve 104 that prevents the pressure applied by the on-off valve 96 from affecting other devices. Furthermore, the air in the pressure accumulating vessel 92 acts as energy storage means.

The pressure accumulating container 92 is connected so as to communicate with the detergent container 100, and when pressurized tap water flows into the pressure accumulating container 92, the air in the pressure accumulating container 92, which is an energy storage means, is compressed, and the detergent container Pressure is applied to the detergent within 100.
The check valve 94 and the on-off valve 96 correspond to the check valve 16 and the on-off valve 18 in the first embodiment, and similarly to these, the check valve 94 and the on-off valve 96 act to feed high-pressure tap water into the pressure accumulating vessel 92. Detailed explanation is omitted.

The pressure release valve 98 is provided on the outlet side of the pressure accumulating vessel 92. When the pressure releasing valve 98 is opened, tap water in the pressure accumulating vessel 92 is discharged, and the pressure in the pressure accumulating vessel 92 decreases.
The detergent container 100 contains a liquid detergent, and the pressure in the pressure accumulating container 92 acts on the surface of the detergent.
The detergent discharge valve 102 is provided at the outlet of the detergent container 100, and is opened when the detergent is used, and discharges pressurized liquid detergent.

Next, the operation of the soap dispenser 90 according to the fourth embodiment of the present invention will be described.
First, in the standby state of the soap dispenser 90, pressurized tap water is stored in the pressure accumulation container 92, and the detergent in the detergent container 100 communicating with the pressure accumulation container 92 is compressed by the air in the pressure accumulation container 92. Has been. When using the detergent, the detergent discharge valve 102 is opened, the air as the energy storage means is expanded, and the detergent in the detergent container 100 is pushed out in the form of foam. When the detergent is pushed out and the pressure in the pressure accumulating container 92 falls below a predetermined pressure, the on-off valve 96 is opened and closed, and pressurized tap water is fed into the pressure accumulating container 92. When the pressure in the pressure accumulating container 92 reaches a predetermined pressure, the opening / closing of the on-off valve 96 is stopped and the on-off valve 96 is closed. When performing maintenance of the soap dispenser 90 such as replenishment of detergent, the pressure release valve 98 is opened to discharge tap water, and the pressure in the pressure accumulating container 92 is reduced. After performing maintenance such as replenishment of detergent, the on-off valve 96 is opened and closed again, the inside of the pressure accumulating container 92 is raised to a predetermined pressure, and the standby state is restored.

  According to the soap dispenser of 4th Embodiment of this invention, tap water is pressurized more than a tap water pressure based on a tap water pressure, and a detergent can be made to foam and discharge by the force based on this pressure.

In particular, the pressure accumulating device of the present invention can be applied to devices other than the flush toilet, lift toilet seat, bath lift and soap dispenser described above, and is particularly suitable for application to devices used around water. ing. In the above-described embodiment, the open / close valve repeats the opened state and the completely closed state at the time of pressure accumulation, but the open / close valve is opened and the flow path is more than this state. It may be configured to repeat the reduced state. Since the flow rate of tap water is also changed by such an operation of the on-off valve, the tap water in the pressure accumulating vessel can be pressurized. In the present specification, “the on-off valve repeats opening and closing” also means such an operation of the on-off valve.
