Description

  The present invention relates to a pressure-feed type toilet device, and more particularly, to a pressure-feed type toilet device that prevents biting by a foreign object that has been misflowed.

  Conventionally, in toilets for general households, drainage is performed using an inclined slope of a drain pipe from a toilet bowl to sewage. However, when installing an additional toilet in the home, it may not be possible to secure a slope due to the layout, etc., or the drainage hose with a small diameter cannot be drained unless the filth is made small like a flush toilet. There is something. As a toilet that can cope with such a case, there is known a pressure-fed toilet device provided with a pulverizing and pressure-feeding processing device that pulverizes filth discharged from a toilet and pulverized filth and washing water to sewage (for example, , See Patent Document 1).

  FIG. 7 shows an example of a pulverized pressure-feed processing device of a conventional pressure-feed type toilet device. The crushing and pressure-feeding processing device 204 includes a motor 224, a rotating shaft 225 connected to the motor 224, and a crushing tooth (cutter) 226 attached to the rotating shaft 225 and an impeller 228 in the storage tank 210.

When the user flows the cleaning water after using the toilet bowl, the filth and the cleaning water are conveyed into the crushing chamber 221 through the supply port 213 of the storage tank 210. At this time, the rotating shaft 225 is rotated by the operation of the motor 224, whereby the grinding teeth 226 and the impeller 228 are rotated.
The grinding teeth 226 are configured to extend obliquely upward from the bottom so as to be rotatable in the space of the grinding chamber 221. The filth is pulverized by the pulverization teeth 226 that are rotationally driven by the motor 224, passes through holes provided in the peripheral wall and the bottom wall of the pulverization chamber 221, and flows out of the pulverization chamber 221. The crushed filth that has flowed out of the pulverization chamber 221 can be pressure-fed through the drain pipe 216 together with the cleaning water by the rotation of the impeller 228 driven by the motor 224.

  By the way, foreign substances other than filth (for example, a hard lighter, a soft diaper, a handkerchief, etc.) may be mistakenly flowed into the toilet bowl. Such foreign matter is difficult to pulverize with pulverized teeth. For this reason, if such foreign matter is accidentally flowed into the toilet bowl, there is a problem that the motor cannot rotate because the foreign matter is caught between the grinding teeth that move and the storage tank that is the fixed part. It was. And if a motor cannot rotate, since drainage cannot be pumped from a storage tank to sewage, there existed a problem that a user could not use a pumping type toilet device until a malfunction was solved.

  In addition, since it is very difficult for a general user to remove foreign matter entangled or bitten by the pulverized teeth, it is necessary to call a specialized service staff to have the foreign matter removed. Furthermore, the work of removing foreign substances from the pulverized teeth is a laborious work. Accordingly, there is a problem that once the pressure-feed toilet device cannot be used due to motor inactivation due to the biting of a foreign object or the like, the state in which the pressure-feed toilet device cannot be used for a long period of time has occurred. For this reason, although there is a demand for the pressure-feed toilet device itself, the above-described problem has prevented the spread of the pressure-feed toilet device.

  The present invention has been made to solve such a problem, and provides a pressure-feed toilet device that can continue to be used even if a foreign object is accidentally washed away. It is aimed.

  In order to achieve the above object, the present invention provides a toilet bowl, water supply means for supplying cleaning water for transporting waste from the toilet bowl, grinding the waste transported from the toilet bowl, A pulverized pressure-feed toilet device that is pumped and discharged to a discharge pipe, the pulverized pressure-feed toilet device having an annular storage tank for storing waste conveyed from the toilet, and the water supply means The lower surface of the storage tank is provided at a lower portion in the annular storage tank and a slight opening is provided between the supply port for introducing the filth conveyed by the storage tank into the storage tank and the inner periphery of the storage tank. A disk-shaped bottom plate provided so as to cover substantially the entire portion, a driving means for rotating the bottom plate, and a discharge port for discharging crushed filth from the storage tank, and the supply Washing water supplied from the mouth to the pulverized pressure-feeding treatment device The inter-water supply flow rate is configured to be larger than the instantaneous discharge flow rate from the discharge port, and the crushing and pressure-feeding processing device rotates the bottom plate by the driving means, thereby cleaning water with filth in the storage tank. It is characterized in that the filth is crushed by stirring and causing the filth to collide with the inner peripheral wall of the storage tank by the force of water.

  According to the present invention configured as described above, the instantaneous water supply flow rate of the cleaning water supplied from the supply port to the pulverization and pressure-feeding processing device is configured to be larger than the instantaneous discharge flow rate from the discharge port. During the cleaning operation, the water level of the cleaning water in the storage tank temporarily rises, and further, the driving means rotates the bottom plate, whereby the cleaning water is agitated at high speed in the storage tank. That is, as the washing water swirls in the storage tank, filth etc. is moved radially outward in the vicinity of the bottom plate, and then rises along the wall of the storage tank, and then moves radially inward and downward after rising, As a whole, convection occurs in the wall of the storage tank.

  As described above, in the present invention, the filth flowed from the toilet bowl into the storage tank by the water flow of the cleaning water in the storage tank is stirred at a high speed together with the cleaning water in the storage tank, so that the filth is soft. It collides with the inner wall of the storage tank and can be crushed finely.

  In the past, crushed filth was crushed by pulverized teeth, and when foreign objects such as lighters, handkerchiefs, and diapers were accidentally flowed into the toilet, the pulverized teeth and surrounding structures rotated by driving means (motors) There is a problem that the motor becomes unable to rotate due to biting between the two.

  On the other hand, in the present invention, the filth is not crushed by the pulverized teeth, but is configured such that the filth is collided with the inner wall of the storage tank by stirring with a water flow, so that the foreign matter is mistaken. Even if it is swept away, it will not get caught. Specifically, since the foreign matter exists only between the water and the wall, there is no place to be caught, so it stays in the storage tank until drainage is completed, and when the drainage is completed, the bottom surface of the storage tank It remains on the bottom plate provided so as to cover substantially the whole, and the driving means is not locked and cannot be used.

Further, in the present invention, when a foreign object is accidentally flowed, the foreign object does not get entangled or bite into the bottom plate as described above, so that the bottom plate can be continuously driven by the driving means. it can. Therefore, conventionally, the toilet device itself cannot be used due to the motor lock, but in the present invention, the bottom plate can be driven by the driving device, so that the user can continue to use the toilet device. This can be said to be a very useful effect especially in portable toilets and the like that are used by people with physical disabilities.
Further, in the present invention, since the crushing teeth are not provided, the foreign matter is not complicatedly entangled or bitten, so it is easier to remove the foreign matter than in the past, and the maintenance property which is complicated is difficult. Can be improved.

In the present invention, preferably, the pulverization and pressure-feeding processing device includes stirring promoting means for promoting stirring of the washing water in the storage tank when the driving means rotates the bottom plate.
According to the present invention configured as described above, by providing the stirring promoting means, when the bottom plate rotates, the swirling force is more efficiently applied to the washing water in the storage tank, and the stirring force is increased. A large strong water stream can be generated. As a result, the turning force imparted to the filth can be increased, and the filth can be reliably crushed.

Further, in the present invention, preferably, a foreign matter collecting means is provided near the rotation center of the bottom plate in the storage tank to collect the soft foreign matter stirred together with the cleaning water by rotating with the bottom plate. It has been.
According to the present invention configured as described above, a soft handkerchief, a diaper, or the like that has been misflowed cannot have the possibility of being entangled during the stay as long as there is a rotating bottom plate. Thus, when the soft foreign matter is stirred together with the washing water in the storage tank, the soft foreign matter convects toward the center of rotation in the storage tank and comes into contact with the foreign substance collecting means that rotates together with the bottom plate. It is surely entangled by the means and staying itself is suppressed. Therefore, even if it is a soft foreign material, the drive means can be reliably prevented from being locked.

Preferably, in the present invention, the agitation promoting means is a movable protrusion that is rotatable on the upper surface of the bottom plate, and this movable protrusion promotes the agitation of the washing water by rotating together with the bottom plate, and collides with the filth. And the direction of rotation can be reversed by collision with dirt.
When the agitation promoting means is provided, the agitation force by the water flow can be increased, but the risk that the drive means is locked due to the foreign matter being caught by the agitation promoting means is increased. However, in the present invention, the agitation promoting means is a movable protrusion, so that when the foreign object is caught, it is configured to move and suppress the catch. You can increase your power.

In the present invention, preferably, the wall of the storage tank is provided with at least one of an opening and an uneven shape portion as a pulverization promoting means for accelerating the pulverization of filth.
According to the present invention configured as described above, when the washing water swirls in the storage tank, the water flow collides with an opening formed in the wall of the storage tank or an uneven shape portion, so that the turbulent flow near the wall. Or the flow of the direction irregular with respect to the turning direction can be produced. Therefore, in the present invention, in addition to swirling and convection of the washing water in the storage tank, turbulent flow or irregular flow can be generated. Therefore, in the present invention, in addition to crushing the waste by colliding with the inner wall of the storage tank by swirling and convection of the washing water, the crushing force can be increased by turbulent flow or irregular flow, which is more efficient. The filth can be crushed.

In the present invention, preferably, the concavo-convex shape is a curved concavo-convex shape.
According to the present invention configured as described above, since the uneven shape of the wall is a curved uneven surface, even if a foreign object collides with the curved uneven shape in the storage tank, it is driven without being caught. The locking of the means can be reliably suppressed.

Preferably, in the present invention, the inner wall of the storage tank facing the bottom plate in the horizontal direction is configured as a circular inner peripheral surface, while the crushing promotion means is provided at a position above the bottom plate by a predetermined distance. It has been.
According to the present invention configured as described above, the inner wall of the storage tank facing the bottom plate is configured as a simple annular inner peripheral surface, so that foreign matter is caught between the rotating bottom plate and the fixed inner wall of the storage tank. It is possible to reliably prevent the driving means from being locked.

  The water supply method of the water supply device 3 may be a water supply direct connection method that supplies water directly connected to a water supply, or a tank method that supplies water from a stored tank. The amount of water supplied to the toilet body 2 is adjusted by the control device 5 controlling the opening and closing of the water supply valve 3b including an electromagnetic valve.

  When the user turns on a cleaning switch for a cleaning command provided in a remote controller (not shown) or the like to clean the toilet body 2 after using the toilet, the control device 5 causes the water supply valve 3b to turn on based on this. A water supply command is output, water is supplied from the water supply device 3 into the toilet body 2 for a predetermined time, and a predetermined amount of washing water is supplied into the toilet body 2.

As shown in FIG. 2, the pulverization / pressure feeding processing device 4 includes a storage tank 10, and a pulverization / pressure feeding unit 20 is provided in the storage tank 10.
The storage tank 10 is a hollow container configured to store washing water and filth that have been conveyed from the toilet body 2. The storage tank 10 is surrounded by the side wall 11 and the bottom wall 12.
A tubular supply port 13 is provided through the side wall 11, and the discharge port 2 a of the toilet body 2 is connected to the supply port 13.
Further, in the storage tank 10, a vent pipe that discharges the air existing in the storage tank 10 to the outside of the storage tank 10 in order to drain the washing water discharged from the toilet body 2 without stagnation. (Not shown) is provided.

  In addition, an opening 12 a is formed in the bottom wall 12, and a pump chamber 14 is attached so as to close the opening 12 a and protrude downward from the bottom wall 12. A discharge port 15 is formed in the pump chamber 14, and a drain pipe 16 is connected to the discharge port 15. As shown in FIG. 1, the drain pipe 16 extends upward from the discharge port 15 and is connected to sewage.

  The crushing and feeding unit 20 includes a bottomed cylindrical crushing chamber 21 disposed in the storage tank 10, a motor 24 serving as a driving unit disposed in the lower part of the pump chamber 14, and the vicinity of the center of the storage tank 10 from the motor 24. A rotary shaft 25 extending to the bottom, an impeller 29 mounted in the pump chamber 14 in the vicinity of the base end of the rotary shaft 25, and a disk-shaped disk mounted near the bottom of the crushing chamber 21 and mounted in the middle of the rotary shaft 25. And a bottom plate 26. In the present embodiment, the motor 24 is disposed at the lower portion of the pump chamber 14, but may be disposed at any position as long as the rotation shaft 25 can be rotated.

  The rotary shaft 25 extends upward from the motor 24 through the pump chamber 14 to the grinding chamber 21. In addition, a notch is formed in the rotary shaft 25 from the top to the tip of the bottom plate 26 in order to increase surface friction. In order to increase the friction, other members such as rubber may be attached to the surface of the rotating shaft 25. The portion 25a above the bottom plate 26 of the rotary shaft 25 is a part that functions as a foreign matter collecting means, and is configured to easily catch and entangle a fibrous soft foreign matter by increasing the friction of the surface. Yes.

The crushing chamber 21 has a cylindrical peripheral wall 22 and a bottom wall 23 that closes a circular opening on the lower side of the peripheral wall 22. The storage tank 10 includes a side wall 11 that is an outer wall of the storage tank 10 and a peripheral wall 22 that is provided inside the storage tank 10 and constitutes an inner wall.
The bottom plate 26 is provided so as to be positioned above the bottom wall 23 of the crushing chamber 21, and a space for receiving cleaning water and filth is secured above the bottom plate 26.

  In the present embodiment, the peripheral wall 22 has an uneven shape that is wavy along at least a portion of the bottom plate 26 in the circumferential direction. This uneven shape is a curved surface. The uneven shape is preferably a smooth curved surface so that foreign matter is not caught. The uneven shape may be formed over the entire height direction of the peripheral wall 22, or may be formed only in the height position corresponding to the side of the bottom plate 26 in the peripheral wall 22 and a predetermined range above and below it. .

By configuring the peripheral wall 22 in this way, in the present embodiment, when the filth is pressed against the peripheral wall 22 by agitation accompanied by convection or swirl or by centrifugal force due to the rotation of the bottom plate 26, the filth is locally applied to the filth. Or concentrated stress can be applied. Moreover, when filth turns in the surrounding wall 22 with a water flow, it collides with the convex part of the surrounding wall 22, and can give local or concentrated stress to filth. That is, when filth collides with the circular peripheral wall 22 in plan view, the contact area between the filth and the peripheral wall 22 is large, and the filth easily moves along the peripheral surface of the peripheral wall 22, so that the impact on the filth is not affected. May weaken. On the other hand, in this embodiment, the filth A can be crushed more easily by colliding with the top part which protrudes inside among the uneven surfaces.
In the present embodiment, the peripheral wall 22 has a curved concavo-convex shape. However, the present invention is not limited to this, and the peripheral wall 22 may be formed to constitute a cylindrical surface having no concavo-convex shape.

In addition, a plurality of holes 22a through which washing water and small filth can pass are formed in the peripheral wall 22 as a wall of the storage tank of the present embodiment. Further, the bottom wall 23 is formed with a plurality of holes 23a through which crushed and reduced filth can pass.
The hole 22 a formed in the peripheral wall 22 is not provided in the vicinity of the height of the bottom plate 26 in the peripheral wall 22, and is formed in a region further upward from the bottom plate 26 by a predetermined height. Further, the hole 22a is formed so that the hole opening area is larger as it is formed higher than the lower part.

Further, a supply port 13 is connected to the peripheral wall 22, and the pulverization chamber 21 receives cleaning water and filth through the supply port 13.
The motor 24 is configured to rotate in a predetermined direction by a control signal from the control device 5.

  As shown in FIGS. 2 to 4, the bottom plate 26 includes a disk member 27 in which a plurality of through holes 27 a are formed, and a plurality of movable protrusions 28 as stirring promoting means fixed to the upper surface of the disk member 27. I have. The movable protrusion 28 is a substantially rectangular parallelepiped member attached so as to protrude upward from the disk member 27, and is rotatably attached to two positions facing each other across the center of the disk member 27. A support shaft 28a is attached to the disk member 27 so as to face a direction perpendicular to the plane thereof, and the movable protrusion 28 is rotatably attached to the support shaft 28a. The support shaft 28a supports the movable projection 28 at a position displaced from the central portion by a predetermined distance in the longitudinal direction so that the movable projection 28 rotates on the bottom plate 26 when the bottom plate 26 rotates.

  The shape of the movable protrusion 28 is not limited to a substantially rectangular parallelepiped, but may be various shapes such as a cube, a polygonal cylinder, and a semi-cylindrical body. Moreover, it is preferable that the corner | angular part of the movable protrusion 28 is smoothly chamfered so that the foreign material mentioned later may not get entangled. Furthermore, the number of the movable protrusions 28 is not limited to two, and may be one or more.

  Further, the through hole 27a is set to a dimension that allows a filth of a size that can be pumped through the drain pipe 16 to pass therethrough. Furthermore, the disk member 27 may be formed in a mesh shape by providing a large number of through holes 27a.

  The disc member 27 is set to have a smaller diameter than the peripheral wall 22 of the crushing chamber 21 so that a predetermined gap G is formed between the disc member 27 and the peripheral wall 22. The gap G has a dimension that allows the filth A, which has been crushed and reduced, to pass through.

  As shown in FIG. 2, the impeller 29 is disposed in the pump chamber 14 and is attached to the rotary shaft 25 so as to rotate together with the bottom plate 26. Sewage flowing into the pump chamber 14 from the storage tank 10 is pumped to the drain pipe 16 by the rotation of the impeller 29.

  In the present embodiment, the movable projection 28 is provided on the bottom plate 26. However, the present invention is not limited to this, and a configuration in which a fixed projection is provided on the bottom plate 26 or a configuration in which such a projection is not provided may be employed. . When the protrusion is not provided, the protrusion does not protrude from the disc member, so that the possibility of tangling with the foreign material or biting of the foreign material can be further reduced.

Next, with reference to FIG.5 and FIG.6, the effect | action of the pressure-feed type toilet device 1 of this embodiment is demonstrated.
In the present embodiment, the bottom plate 26, the peripheral wall 22, the movable projection 28, and the like that are rotationally driven by the motor 24 are filth (solid matter such as feces and toilet paper) in the sewage transported from the toilet body 2 into the crushing chamber 21. It is comprised so that it may function as a crushing means which grinds.
In the present embodiment, the impeller 29 and the pump chamber 14 that are rotationally driven by the motor 24 function as a pressure feeding unit that pumps sewage containing crushed filth to the drain pipe 16.

  When the user turns on a cleaning switch (not shown), the control device 5 switches the position of the water supply valve 3b from the closed state to the open state for a predetermined time. At this time, the control device 5 outputs a control signal to the motor 24 and operates the motor 24 for a predetermined time.

  As shown in FIG. 5, the discharge flow rate Fb (broken line) by the pumping means is constant. On the other hand, the water supply flow rate Fa (solid line) of the cleaning water supplied from the water supply means 3 via the water supply valve 3b in a single water supply operation or water supply treatment instantaneously exceeds the discharge flow rate Fb of the pumping means. Rises and then decreases. On the other hand, when the cleaning water is supplied to the storage tank 10, the water level of the cleaning water W in the storage tank 10 temporarily rises during a period when the feed water flow rate Fa is larger than the discharge flow rate Fb. FIG. 6 shows a state where the water level has risen.

  The washing water supplied together with the filth in the crushing chamber 21 flows toward the bottom of the crushing chamber 21, and part of it flows out to the storage tank 10 through the hole 22 a of the peripheral wall 22. Further, when the impeller 29 is rotated by driving the motor 24, the cleaning water and filth in the peripheral wall 22 are sucked toward the bottom of the storage tank 10.

  As shown in FIG. 6, when the bottom plate 26 is rotationally driven by the motor 24, a vortex is formed in the storage tank 10 or the crushing chamber 21. That is, swirl force is given to the cleaning water W whose water level has risen temporarily by the rotation of the bottom plate 26, and the cleaning water W is pushed along the peripheral wall 22 while being rotated along the peripheral wall 22. Although the washing water W is also stirred by the rotation of the bottom plate 26, in this embodiment, the movable projection 28 as the stirring promoting means rotates together with the bottom plate 26, so that the stirring force is increased and the stirring can be promoted. Since the movable protrusion 28 has a large resistance force against the cleaning water on the bottom plate 26, a large turning force can be applied to the cleaning water W by rotating the movable protrusion 28, and a strong water flow is generated. Is possible. Accordingly, as shown in FIG. 6, the cleaning water W is stirred so that the water level of the cleaning water W is low near the rotation center of the bottom plate 26 and the water level on the radially outer side is high.

  At this time, in the vicinity of the bottom plate 26, the cleaning water and filth move outward in the radial direction, and a part of the cleaning water hitting the peripheral wall 22 flows upward along the peripheral wall 22. Then, the washing water that has moved upward along the peripheral wall 22 again moves toward the center of the crushing chamber 21 and moves downward from the vicinity of the rotating shaft 25. In this way, the washing water swirls and convects in the crushing chamber 21.

  As shown in FIGS. 3 and 6, the filth A is pushed onto the peripheral wall 22 of the crushing chamber 21 by the water flow on the bottom plate 26 and the centrifugal force generated by the rotation of the bottom plate 26. At this time, the filth A collides with the rotating movable protrusion 28 and is finally pushed to the peripheral wall 22 of the crushing chamber 21 while changing the moving direction.

Then, the filth A is crushed by being exposed to a strong water flow while moving in the crushing chamber 21 by swirling and convection by stirring of the washing water.
Further, when the cleaning water swirls in the crushing chamber 21, the water flow collides with the curved irregularities provided on the peripheral wall 22, and a turbulent flow or an irregular flow occurs in the vicinity of the peripheral wall 22 with respect to the swirling direction. When the filth A moves in the vicinity of the peripheral wall 22, the turbulent flow or the irregular flow receives a shearing force and promotes crushing.
In the present embodiment, since the uneven shape provided on the peripheral wall 22 is a curved surface, even if the swirling washing water collides with the uneven shape of the peripheral wall 22, the momentum of the swirling force of the cleaning water is not easily attenuated. ing. Thereby, in this embodiment, a turbulent flow or an irregular flow is produced, maintaining a turning power of washing water, and filth can be efficiently crushed by stirring of washing water.

  Also, when moving by water flow or centrifugal force, crushing of filth is promoted by repeatedly colliding with the peripheral wall 22 of the uneven surface, the movable projection 28, etc., and it can be pulverized to a sufficiently small state, improving the pulverization efficiency. It becomes possible to make it.

  Further, when the bottom plate 26 is rotationally driven by the motor 24, the movable protrusion 28 rotates on the disk member 27 because the weight balance across the support shaft 28a is not uniform. When the filth A reaches the bottom plate 26, it collides with the rotating movable projection 28 and is crushed by receiving a large impact force, and further to the peripheral wall 22 in a direction different from the direction of the water flow direction or centrifugal force. It is made to collide. Thereby, the filth can be crushed more efficiently by the bottom plate 26 and the movable protrusion 28.

  Note that when the rotating movable protrusion 128 collides with a hard foreign object or large dirt, the movable protrusion 28 receives a repulsive force from the foreign object or dirt, and depending on the magnitude of the repulsive force, the rotating direction at the time of the collision And rotated in the opposite direction. Thereby, it is possible to prevent foreign matters and dirt from being caught between the movable protrusion 28 and the peripheral wall 22.

  In this way, the small pieces of the filth A crushed in the crushing chamber 21 pass through the gap G, and further pass through the hole 23 a of the bottom wall 23 and are carried to the pump chamber 14. The crushed filth A is pumped by the impeller 29 in the pump chamber 14 and discharged to the sewage through the drain pipe 16.

  In the present embodiment, the radial distance between the outer end of the movable protrusion 28 and the peripheral wall 22 is set to be larger than the gap G, and the crushing means is filth between the movable protrusion 28 and the peripheral wall 22. Crushing and crushing is not the main function. Rather, the pulverizing means of the present embodiment pulverizes the filth by the stirring force of the washing water caused by the rotation of the bottom plate 26. Furthermore, the crushing of filth is assisted by the impact force caused by the collision with the movable protrusion 28 or the impact force caused when the bottom plate 26 is caused to collide with the peripheral wall 22 by the centrifugal force.

  Moreover, in this embodiment, the grinding | pulverization means is formed with the disk-shaped bottom plate 26 and the surrounding wall 22, and does not have the grinding | pulverization tooth | gear for fracture | rupturing filth like the past. Conventionally, the grinding teeth extend obliquely upward into the space of the grinding chamber. However, in this embodiment, the bottom plate 26 is simply provided with a movable protrusion 28. The movable projection 28 is not configured to extend into the space of the crushing chamber 21, protrudes slightly from the disk member 27 of the bottom plate 26, and only rotates at the bottom of the crushing chamber 21.

  For this reason, even if a foreign material such as a diaper is accidentally flowed into the toilet body 2, the bottom plate 26 does not get tangled with the foreign material. In particular, fiber foreign materials such as handkerchiefs, paper and cloth diapers, string-like objects, cloth-like objects, rubber products, etc. have been easy to get entangled with the crushed teeth, and this makes the motor torque insufficient and the motor cannot rotate. It was. On the other hand, in the present embodiment, the bottom plate 26 is not provided with pulverized teeth and is merely formed with the movable protrusion 28, so even if fibrous foreign matter flows in, The fibrous foreign matter does not get entangled with the bottom plate 26 and the motor 24 cannot be rotated.

  Further, in the present embodiment, the pulverizing means has a disk-shaped bottom plate 26 as a rotating body, and has a simple configuration in which a predetermined gap G is provided between the bottom plate 26 and the peripheral wall 22, so that foreign matters are not generated. Even if it is a fibrous foreign material, biting between the bottom plate 26 and the peripheral wall 22 can be significantly suppressed. Thereby, in this embodiment, the possibility that foreign matter may bite into the motor and stop the motor as in the past can be greatly reduced.

  Further, in this embodiment, when the user turns on the cleaning switch as described above, the water level in the crushing chamber 21 rises as shown in FIG. Float in water and further convection. When the foreign matter reaches the vicinity of the rotary shaft 25 by this convection, the foreign matter can be entangled with the rotating rotary shaft 25. In the present embodiment, the portion 25a of the rotating shaft 25 constitutes a foreign matter collecting means having an increased surface frictional force so as to easily catch the fibrous foreign matter.

  Accordingly, when the fibrous foreign matter comes into contact with the surface of the rotary shaft 25, the foreign matter is quickly entangled with the rotating rotary shaft 25. And once a foreign material is entangled in the rotating shaft 25, it will be hold | maintained in the state. Even if the foreign matter is entangled with the rotary shaft 25, the foreign matter is located at the center of the bottom plate 26, so that an increase in torque when the motor 24 rotates the bottom plate 26 can be suppressed. Can be prevented from being overloaded. As described above, in this embodiment, while the fibrous foreign matter remains in the crushing chamber 21, the foreign matter can be entangled with the rotating shaft 25, so that the foreign matter is between the bottom plate 26 and the peripheral wall 22. Biting can be reliably prevented.

Further, in the present embodiment, in order to more reliably prevent foreign matter from being caught between the bottom plate 26 and the peripheral wall 22 to cause a lock due to biting, a hole 22a is formed in the peripheral wall 22 near the height of the bottom plate 26. The structure is not formed. That is, the hole 22a is not formed in the vicinity of the bottom plate 26 because foreign matter is more easily caught than a smooth wall surface. Thereby, in the vicinity of the bottom plate 26, the hole 22 a is not formed in the peripheral wall 22, and is formed in a smooth curved uneven shape, so that foreign matter is generated between the bottom plate 26 and the movable protrusion 28 and the peripheral wall 22. It is more reliably prevented that the catch is generated.
In the peripheral wall 22, a hole 22 a is formed in a region higher than the bottom plate 26 by a predetermined height or more and not pinched with the bottom plate 26 so that the hole opening area increases toward the upper side. From the upper part of the storage tank 10, it is possible to easily discharge the washing water and the suspended filth.

  As described above, in this embodiment, when the fibrous foreign matter has been washed away, the portion 25a of the rotating shaft 25 as the foreign matter collecting means entangles the foreign matter and is fixed (for example, a lighter). If foreign matter has been washed away, the foreign matter continues to stay on the bottom plate 26. In this way, in this embodiment, no matter what foreign matter has flowed, the foreign matter does not hinder the rotation of the bottom plate 26 and the motor 24 does not lock. Even in the storage tank 10, the motor 24 can be driven. Therefore, in this embodiment, the user can continue to use the pressure-fed toilet device 1 until the service staff comes even after the foreign object has been accidentally flown.

Next, the present embodiment may be modified as follows.
In the said embodiment, although the storage tank 10 is provided with the side wall 11 which is an outer wall, and the surrounding wall 22 which is an inner wall, the surrounding wall 22 comprises a part of grinding | pulverization pumping part 20, but it is not restricted to this. Alternatively, the peripheral wall 22 may not be provided. In this case, it is preferable to expand the diameter of the bottom plate 26 in accordance with the side wall 11.
