Description

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

Conventionally, in a toilet device for general household use, drainage is performed using a gradient of a drain pipe from a toilet bowl to sewage. However, in the case where an additional toilet is installed in the home, there are many cases where the gradient cannot be secured due to the layout or the like. As a toilet device that can cope with such a case, there is known a pressure-fed toilet device equipped 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. 13 shows an example of a pulverization and 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 uses flushing water after using the toilet, the filth and the washing water are conveyed into the crushing chamber 221 through the inlet 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, the motor 6 cannot be rotated because the foreign matter bites between the grinding teeth that are the movable part and the storage tank that is the fixed part. Had occurred. And if a motor cannot rotate, since drainage cannot be pumped from a storage tank to sewage, there was a problem that a user would not be able to use a pumping-type toilet device until the trouble is solved.

  In addition, it is very difficult for a general user to remove foreign matter that has become entangled or bitten by the pulverized teeth, and it takes a lot of time and effort. there were. Therefore, there is a problem that once the pressure-fitted toilet apparatus cannot be used due to motor inactivation due to the biting of a foreign object or the like, the state where the pressure-fed toilet apparatus cannot be used for a long period of time has occurred. For this reason, although there is a demand for the pressure-feed toilet apparatus itself, the above-described problem has prevented the spread of the pressure-feed toilet apparatus.

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

In order to achieve the above object, the present invention receives a toilet, a supply means for supplying cleaning water for discharging filth from the toilet, and sewage which is cleaning water mixed with filth discharged from the toilet, And a processing device for compressing and pumping finely, the processing device includes a storage tank for storing the sewage discharged from the toilet by flowing into the interior from the inflow port, and a storage tank A rotating member provided at a lower portion, a disc-shaped bottom plate provided so as to cover a lower surface portion of the storage tank leaving a slight gap between the inner peripheral portion of the storage tank, and an upper surface of the bottom plate A rotating member having a stirring protrusion provided so as to protrude upward from, a driving means for rotating the rotating member, and a discharge port for discharging the stirred sewage from the storage tank, rotation of the rotary member by the processing apparatus, drive motion means The Rukoto, finely dirt by stirring the sewage in the reservoir, is configured to increase the sewage liquidity.

  According to the present invention configured as described above, since the instantaneous inflow flow rate of the cleaning water supplied from the inflow port to the processing device is larger than the instantaneous discharge flow rate from the discharge port, the cleaning operation is being performed. In this case, the level of sewage in the storage tank rises temporarily, and the drive means rotates the bottom plate, whereby the sewage is stirred at high speed in the storage tank. That is, when the sewage swirls in the storage tank, filth etc. is moved radially outward near the bottom plate, and then rises along the wall of the storage tank, and then moves radially inward and downward after the rise. As a convection in the wall of the storage tank.

  As described above, in the present invention, the filth flowing from the toilet bowl into the storage tank by the flow of sewage in the storage tank is stirred together with the sewage in the storage tank, thereby reducing the filth and improving the fluidity. Can do.

  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 (motor) There is a problem that the motor 224 becomes unable to rotate due to the biting between the two.

  On the other hand, in the present invention, the filth is not crushed by the pulverized teeth, but the filth is made fine by stirring with a water flow, and the fluidity is increased. Also, it does not become fine by stirring and does 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 the part, 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.

  If it is going to make a filth fine by stirring, it will require a long time compared with the conventional crushing tooth. In the present invention, further, a contrivance is made to shorten the time and enable quick pumping.

In other words, the present invention further includes a thin plate-like cutting projection formed so as to protrude upward from the upper surface of the bottom plate and extending in a tangential direction with respect to a virtual circle centered on the rotation axis of the bottom plate.

  According to the present invention configured as described above, when the rotating member in the storage tank rotates, the filth moves so as to turn around the rotation axis of the rotating member. When the cutting protrusions come into contact with the protrusions and the cutting protrusions bite into the filth, the filth moves relatively along the cutting protrusions. Since the cutting projection extends in a tangential direction with respect to a virtual circle centered on the rotation axis of the bottom plate, the centrifugal force acting on the filth moving along the cutting projection becomes a shearing force that tears the filth. As a result, the filth is torn and becomes finer in a shorter time. As a result, it is possible to provide a practically superior pumping toilet apparatus that can pump in a short time without entanglement of foreign matter.

  In the present invention, preferably, the cutting projection is provided at least in a portion near the end portion on the outer peripheral side of the bottom plate. According to the present invention configured as described above, since the sewage turning in the storage tank is directed to the outer peripheral side by centrifugal force, the cutting protrusion is provided at least on the portion near the end on the outer peripheral side of the bottom plate. The contact frequency between the filth and the cutting projection can be increased, and the filth can be made finer in a shorter time.

  Moreover, if the sewage in the storage tank is excessively stirred upward by the cutting projections, the filth is wound up, and the contact frequency between the filth and the cutting projections is reduced. Preferably, in the present invention, a plurality of cutting projections are provided, of which the outer peripheral cutting projection provided near the outer peripheral end of the bottom plate is closer to the rotating shaft side of the rotating member than the outer peripheral cutting projection. The length in the tangential direction is smaller than that of the center-side cutting protrusion provided on the surface. According to the present invention configured as described above, the outer peripheral cutting projections having a relatively high circumferential speed are formed smaller than the central cutting projections having a relatively low speed. It is possible to prevent the sewage from being excessively stirred upward, and to make the filth finer in a shorter time.

  In addition, if the sewage in the storage tank is excessively stirred upward by the stirring protrusion, the filth is wound up, and the contact frequency between the filth and the cutting protrusion is reduced. Preferably, in the present invention, a first inclined portion that forms a downward gradient is provided at an end of the stirring protrusion opposite to the rotation direction. According to the present invention thus configured, the filth wound up by the stirring protrusions can be provided by providing the first inclined part that has a downward slope at the end opposite to the rotation direction of the stirring protrusions. It is possible to form a flow of water that is directed again to the upper surface of the rotating member, and it is possible to increase the frequency of contact with the cutting projection. Further, since cavitation is not generated between the end portion of the stirring protrusion and the bottom plate, it is possible to prevent a situation in which bubbles are generated and filth cannot be pumped by so-called air biting.

  In the present invention, it is preferable that the cutting protrusion is provided with a second inclined portion that is inclined downward toward a tangential direction opposite to the rotation direction. According to the present invention configured as described above, while the filth is made fine, cavitation is not generated between the end portion of the cutting projection and the bottom plate, and the filth is made fine by the cutting projection. Thus, by creating a flow that guides the flow of sewage toward the upper surface of the bottom plate, the filth can be made fine in a short time, and the filth can be pumped more reliably.

  In the present invention, preferably, a cutting projection is provided on the upper surface of the inclined surface formed on the stirring projection. According to the present invention configured as described above, the filth is guided toward the upper surface of the bottom plate by the inclined portion provided on the stirring protrusion, thereby cutting the filth sufficiently guided toward the upper surface of the bottom plate. Therefore, the cutting projection can be brought into contact with the filth, and the filth can be made finer and more efficiently.

  ADVANTAGE OF THE INVENTION According to this invention, even if it is a case where a foreign material has been washed away accidentally, the pumping toilet apparatus which can provide the pumping toilet apparatus which can continue use can be provided. It is a thing.

The toilet body 2 may be provided with a flap valve at the inlet 2a. The toilet body 2 may be a siphon type or siphon jet type toilet.

  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. Further, the control device that controls the water supply valve 3 b may be another control device that is divided from the control device 5.

  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.

FIG. 2 is a cross-sectional view showing a pressure-feed toilet apparatus. As shown in FIG. 2, the processing apparatus 4 includes a storage tank 10, and a stirring unit 20 is provided in the storage tank 10.
The storage tank 10 is a hollow container configured to store wash water and filth that have flowed in from the toilet body 2. The storage tank 10 is surrounded by the side wall 11 and the bottom wall 12.
A tubular inflow port 13 is provided through the side wall 11, and the inflow port 2 a of the toilet body 2 is connected to the inflow 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) or a pressure relief device for preventing the pressure in the storage tank 10 from increasing.

An opening 12 a is formed in the bottom wall 12, and a pump chamber 14 is attached so as to 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 from the discharge port 15 and is further connected to sewage.

  The stirring unit 20 includes a bottomed cylindrical stirring chamber 21 disposed in the storage tank 10, a motor 6 as a driving unit disposed in the upper part of the storage tank 10, and a rotating shaft extending from the motor 6 to the pump chamber 14. 7, an impeller 9 mounted in the pump chamber 14 near the proximal end of the rotating shaft 7, and a stirring plate that is attached to the middle portion of the rotating shaft 7 and is a disk-shaped bottom plate located near the bottom of the stirring chamber 21. And wings 8. In addition, in this embodiment, although the motor 6 is arrange | positioned at the storage tank 10 upper part, as long as the rotating shaft 7 can be rotated, you may arrange | position in arbitrary positions.

  The rotating shaft 7 extends from the motor 6 through the stirring chamber 21 to the pump chamber 14. Further, the rotary shaft 7 is a part having a function as a foreign matter collecting means, and is configured to easily trap and entangle a fibrous soft foreign matter by increasing the friction of the surface. .

The stirring 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 stirring blade 8 is provided so as to be positioned above the bottom wall 23 of the stirring chamber 21, and a space for receiving cleaning water and filth is secured above the stirring blade 8.

  In the present embodiment, the peripheral wall 22 has an uneven shape along at least a part of the stirring blade 8 in the circumferential direction. The uneven shape may be formed over the entire height direction of the peripheral wall 22 or may be formed only in a height position corresponding to the side of the stirring blade 8 in the peripheral wall 22 and a predetermined range above and below the height position. Good.

By configuring the peripheral wall 22 in this manner, in the present embodiment, when the filth is pressed against the peripheral wall 22 by agitation accompanied by convection or swirl or by the centrifugal force due to the rotation of the agitating blade 8, 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, an inlet 13 is connected to the peripheral wall 22, and the stirring chamber 21 receives cleaning water and filth through the inlet 13.
The motor 6 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 stirring blade 8 is provided with a plurality of stirring protrusions 27 as stirring promoting means fixed to the upper surface. The agitation protrusion 27 is constituted by a receding wing member provided so as to protrude upward from the agitation blade 8.

  The shape of the stirring protrusion 27 is not limited to the receding wing shape, and may be various shapes such as a cube, a polygonal column, and a semi-cylinder. Furthermore, the number of the stirring protrusions 27 is not limited to two, but may be one or more.

  The stirring blade 8 is set to have a smaller diameter than the peripheral wall 22 of the stirring chamber 21 so that a predetermined gap G is formed between the stirring blade 8 and the peripheral wall 22. This gap G is a dimension through which the filth that has been stirred and becomes fine can pass.

  As shown in FIG. 2, the impeller 9 is disposed in the pump chamber 14 and is attached to the rotating shaft 7 so as to rotate together with the stirring blade 8. The 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 9.

  In this embodiment, the stirring protrusion 27 fixed to the stirring blade 8 is provided. However, the present invention is not limited to this, and the stirring protrusion 8 may be provided with the stirring protrusion.

  Furthermore, a thin-plate-like cutting projection 28 extending in the tangential direction 27b is provided for a virtual circle 27a centering on the rotating shaft 7 of the stirring blade 8. In addition to the stirring protrusions 27 whose main purpose is stirring of the water in the storage tank 10, by providing the cutting protrusions 28 whose main purpose is cutting of filth, the filth can be more effectively refined, The operation can be completed in a short time.

  The cutting projections 28 are provided at least in a portion near the end portion on the outer peripheral side of the stirring blade 8, and can be effectively brought into contact with filth bounced to the outer peripheral side by centrifugal force. ing.

  Further, the cutting projection 28 is formed with a smaller length in the tangential direction on the outer peripheral side than on the rotary shaft 7 side, such as Ha and Hb, so as not to disturb the water flow excessively when rotating. Has been.

  Further, the stirring protrusion 27 on the stirring blade 8 is formed with a first inclined portion 30 having a downward slope at the end opposite to the rotation direction. The first inclined portion 30 is formed to lower the resistance coefficient, and can form a flow of water that is directed toward the upper surface of the stirring blade 8, thereby increasing the contact frequency with the cutting projection 28. It becomes possible.

  In addition, since the generation of cavitation by the stirring protrusion 27 can be suppressed and no bubbles are generated, there is an effect of preventing air from being caught in the pump chamber 14.

  Further, the cutting projection 28 is formed with a second inclined portion 31 having a downward slope at an end opposite to the rotation direction. Similarly to the first inclined portion 30, the second inclined portion 31 is also formed to reduce the resistance coefficient, and it is possible to form a flow of water that is directed toward the upper surface of the stirring blade 8, and for cutting. The frequency of contact with the protrusions 28 can be increased.

  In addition, since the generation of cavitation by the cutting projections 28 can be suppressed and no bubbles are generated, there is also an effect of preventing air biting in the pump chamber 14.

  Further, the cutting projections 28 are formed on the upper surface of the stirring projections 27, so that the frequency of contact with the agitated dirt can be improved.

  Of the cutting protrusions 28, at least the outer peripheral cutting protrusion 28a may be formed in an arc shape centered on the rotation axis of the rotating member.

The rotating shaft 7 extends from the motor 6 through the stirring chamber 21 to the pump chamber 14.
Further, the rotating shaft 7 has a foreign matter collecting means 7a that protrudes in the outer peripheral direction, and is configured to easily catch and entangle the fibrous foreign matter. In order to increase the friction, notches may be formed, or other members such as rubber may be attached to the surface of the rotating shaft 7.

  Moreover, the foreign material collection means 7a is provided in the position facing the inflow port 2a, and it is comprised so that a contact frequency may become high when filth is carried into the storage tank 10 from the toilet bowl 2. FIG.

  Further, since the foreign matter collecting means 7a is formed to be smaller than the stirring blade 8, it is considered not to increase the torque so as to inhibit the rotation of the motor 6 when the foreign matter is entangled. Since the cross section of the storage tank 10 is not blocked over a wide range when entangled, the long-term continuous use becomes possible.

  Further, the foreign matter collecting means 7a is formed so as to taper from the rotating shaft 7 toward the outer peripheral direction, and when the foreign matter is entangled, the service staff can easily remove the foreign matter in a short time.

  The foreign matter collecting means 7a is formed so as to be a flat plate in the direction opposite to the rotation direction. When the rotary shaft 7 rotates, the foreign matter collecting means 7a causes turbulent flow, and The contact frequency is prevented from being lowered.

  Further, the rotary shaft 7 is provided with a large diameter portion 29 having a large diameter on the side of the stirring blade 8, and even when the foreign matter collected by the foreign matter collecting means 7 a slides down, the large diameter portion 29 is provided. It is possible to prevent the stirring protrusion 27 and the cutting protrusion 28 from being covered with foreign matter.

Next, with reference to FIG. 1 and FIGS. 5-12, the effect | action of the crush-type toilet apparatus 1 of this embodiment is demonstrated.
In the present embodiment, the stirring blade 8, the peripheral wall 22, the protrusion 28, and the like that are rotationally driven by the motor 6 are filth in solid water (solid matter such as feces and toilet paper) that flows into the stirring chamber 21 from the toilet body 2. It is configured to function as a means for reducing the size.
In the present embodiment, the impeller 9 and the pump chamber 14 that are rotationally driven by the motor 6 function as pressure feeding means that pressure-feeds sewage containing filth that is fine and has improved fluidity 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 6 to operate the motor 6 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 stirring chamber 21 flows out to the storage tank 10 through the hole 22a of the peripheral wall 22, and part of the cleaning water also flows out toward the bottom of the stirring chamber 21. Further, when the impeller 9 is rotated by driving the motor 6, 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 stirring blade 8 is rotationally driven by the motor 6, a vortex is formed in the storage tank 10 or the stirring chamber 21. That is, swirl force is given to the cleaning water W whose water level has temporarily increased by the rotation of the stirring blade 8, 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 stirring blade 8, in this embodiment, the stirring protrusion 27 as the stirring promoting means rotates together with the stirring blade 8, so that the stirring force is increased and the stirring can be promoted. Since the stirring protrusion 27 has a large resistance force against the cleaning water on the stirring blade 8, a large turning force can be applied to the cleaning water W by rotating the stirring protrusion 27, and a strong water flow is generated. Can be generated. 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 stirring blade 8 and the water level on the radially outer side is high.

  At this time, in the vicinity of the stirring blade 8, the cleaning water and the filth move radially outward, 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 stirring chamber 21 and moves downward from the vicinity of the rotating shaft 7. In this way, the washing water swirls and convects in the stirring chamber 21.

  The filth A is pushed onto the peripheral wall 22 of the stirring chamber 21 by the water flow on the stirring blade 8 and the centrifugal force generated by the rotation of the stirring blade 8. At this time, the filth A collides with the rotating stirring protrusion 27 and the cutting protrusion 28 and is finally pushed to the peripheral wall 22 of the stirring 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 stirring chamber 21 by swirling and convection by stirring the washing water.
Further, when the washing water swirls in the stirring chamber 21, the water flow collides with the unevenness 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 addition, when moving by water flow or centrifugal force, by repeatedly colliding with the peripheral wall 22 of the uneven surface, the agitation protrusion 27, the cutting protrusion 28, etc., crushing of filth is promoted, and it can be made fine enough. It is possible to improve the stirring efficiency.

  In this way, the small pieces of the filth A crushed in the crushing chamber 21 pass through the hole 22 a of the peripheral wall 22 and are carried to the pump chamber 14. The filth A that has been agitated and improved in fluidity is pumped by the impeller 9 in the pump chamber 14 and discharged to the sewage through the drain pipe 16.

Next, with reference to FIG. 7 to FIG. 9 and FIG. In the stirring chamber 21, the water stirred by the stirring protrusion 27 flows in the direction of the cylindrical peripheral wall 22 by centrifugal force. At that time, when the filth comes into contact with the rotating projection 28, the filth is divided into the cylindrical peripheral wall 22 side and the rotary shaft 7 side starting from the contact point. The filth on the cylindrical peripheral wall 22 side is caused to flow toward the cylindrical peripheral wall 22 side by centrifugal force, and the filth on the rotating shaft 7 side tends to be held by the cutting projection. By these, filth is divided.

  Further, the first inclined portion 30 is provided at the end opposite to the rotation direction of the stirring protrusion 27, and the second inclined portion 31 is provided at the end opposite to the rotation direction of the cutting protrusion 28. Since the water flow is generated on the lower side when the stirring blade 8 rotates, the frequency with which the filth comes into contact with the cutting projections 28 is increased.

Further, at least the outer peripheral cutting projection 28a is formed in an arc shape with the rotation axis of the rotating member as the center, thereby making it difficult to generate cavitation from the outer peripheral cutting projection having a high peripheral speed. Yes. Thus, the waste can be efficiently and finely divided by the cutting projections 28 without hindering the function of pumping.

  In addition, the inclination angle of the first inclined portion is set so that the inclination angle θA of the portion near the outer periphery of the rotating member is smaller than the inclination angle θB of the portion of the rotating member close to the rotation axis, so Even with the washing water flowing through the portion, the water flow can be smoothly directed relatively to the upper surface of the bottom plate without being separated from the first inclined portion.

  That is, in the portion near the rotation axis of the rotating member, a relatively large inclination angle is provided so that a portion where neither the stirring protrusion nor the cutting protrusion is formed on the upper surface of the bottom plate of the rotating member can be provided widely. As described above, it is possible to make sure that dirt is brought into contact with the cutting projections and cut, while in the portion near the outer periphery of the rotating member, even a flow of water with a high flow rate is relatively directed to the upper surface of the bottom plate, At the same time, since the filth can be attracted to the upper surface of the bottom plate, the filth can be reliably brought into contact with the cutting projection.

Next, foreign matter collecting means will be described with reference to FIGS. 2, 10, and 11.
The stirring means of this embodiment makes the filth fine by the stirring force of the washing water caused by the rotation of the stirring blade 8. Furthermore, the stirring of the filth is assisted by the impact force caused by the collision with the stirring projection 27 and the cutting projection 28, the impact force when the impact is caused by the centrifugal force generated by the rotation of the stirring blade 8 and the collision with the peripheral wall 22.

  Moreover, in this embodiment, it 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 stirring chamber. However, in this embodiment, the stirring blade 8 is simply provided with the stirring protrusion 27 and the cutting protrusion 28. Yes. These protrusions are not configured to extend into the space of the stirring chamber 21, protrude slightly from the disk member 27 of the stirring blade 8, and only rotate at the bottom of the stirring chamber 21.

  For this reason, even if a foreign material such as a diaper is accidentally flowed into the toilet body 2, the stirring blade 8 is not entangled 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 this embodiment, the stirring blade 8 is not provided with pulverized teeth, and only the stirring protrusions 28 and the cutting protrusions 29 are formed. Even in this case, the fibrous foreign matter does not get entangled with the stirring blade 8 and the motor 6 does not become unrotatable.

Further, in this embodiment, the stirring means has a disk-shaped stirring blade 8 as a rotating body and has a simple configuration in which a predetermined gap G is provided between the stirring blade 8 and the peripheral wall 22. Even if the foreign matter is a fibrous foreign matter, it is possible to greatly suppress biting between the stirring blade 8 and the peripheral wall 22.
Thereby, in this embodiment, the possibility that a foreign object may bite and the motor 6 may stop as in the conventional case can be greatly reduced.

  In the present embodiment, when the user turns on the cleaning switch as described above, the water level in the stirring chamber 21 rises as shown in FIG. Float in water and further convection. When the foreign matter reaches the vicinity of the rotary shaft 7 by this convection, the foreign matter can be entangled with the rotating rotary shaft 7. In the present embodiment, the portion 7a of the rotating shaft 7 constitutes a protruding foreign matter collecting means so as to easily catch the fibrous foreign matter.

  Therefore, when the fibrous foreign matter comes into contact with the surface of the rotary shaft 7, the foreign matter is quickly entangled with the rotating rotary shaft 7. And once a foreign material is entangled in the rotating shaft 7, it will be hold | maintained in the state. Further, even if the foreign matter is entangled with the rotating shaft 7, the foreign matter is located in the center of the stirring blade 8, so that an increase in torque when the motor 6 rotates the stirring blade 8 can be suppressed. It is possible to prevent the motor 6 from being overloaded. As described above, in this embodiment, while the fibrous foreign matter remains in the stirring chamber 21, the foreign matter can be entangled with the rotating shaft 7, so that the foreign matter is between the stirring blade 8 and the peripheral wall 22. Can be prevented from being bitten.

  However, since the rotating shaft 7 is very small with respect to the volume of the entire stirring chamber 21, foreign matter may not get tangled. Therefore, the rotating shaft 7 is provided with the foreign matter collecting means 7a extending in the outer peripheral direction, so that the foreign matter can be reliably wound up.

  Further, since the foreign matter collecting means 7a is provided at a position facing the inflow port 2a, the foreign matter is brought into contact with the foreign matter collecting means 7a when the filth is carried into the storage tank 10 from the toilet bowl 2. Is increasing. As a result, the foreign matter can be taken up immediately after the start of operation, and the stirring efficiency can be prevented from being lowered.

  Moreover, since the foreign material collection means 7a is formed smaller than the stirring blade 8, it does not increase to a large torque that inhibits the rotation of the motor 6 when the foreign material is entangled. If the foreign matter collecting means 7 is equal to or larger than the stirring blade 8, if the foreign matter is wound around the outer peripheral side of the foreign matter collecting means, the torque to the motor 6 is extremely increased, and even a small amount of foreign matter is caused by a high load. A lock may occur.

Further, when the foreign matter collecting means 7a is formed to be equal to or larger than the stirring blade 8, when the foreign matter is wound around the outer peripheral side of the foreign matter collecting means, the stirring chamber 21 is blocked over a wide range of the cross section. The flow of the water flow in the chamber 21 may be obstructed, and the filth to be stirred may not be able to contact the pulsator. However, according to the present invention, the foreign matter collecting means 7a is formed smaller than the stirring blade 8, and thus does not hinder the flow of water.

  Furthermore, since the foreign matter collecting means 7a is formed so as to taper from the rotating shaft 7 toward the outer peripheral direction, even when the foreign matter is entangled, the foreign matter can be taken out by pulling the foreign matter to the outer peripheral side. The service staff can easily remove foreign substances in a short time.

  Moreover, since the foreign material collection means 7a is formed so that it may become a flat plate in the direction opposite to the rotation direction, the foreign material collection means 7a may cause turbulent flow when the rotating shaft 7 rotates. Can be reduced. Thereby, since the foreign material does not reduce the frequency of contact with the foreign material collecting means 7a, the foreign material can be reliably collected.

  Further, since the rotary shaft 7 is provided with a large diameter portion 29 having a large diameter on the side of the stirring blade 8, even when the foreign matter collected by the foreign matter collecting means 7a slides downward, the large diameter portion It became possible to hook at 29. As a result, the stirring protrusions 27 and the cutting protrusions 28 can be prevented from being covered with foreign matter, and the stirring performance can be ensured for a long period of time.

  Furthermore, in the present embodiment, in order to more reliably prevent foreign matter from being caught between the stirring blades 8 and the peripheral wall 22, a lock due to biting is prevented, so that a hole is formed in the peripheral wall 22 near the height of the stirring blade 8. 22a is not formed. That is, the holes 22a are not formed in the vicinity of the stirring blade 8 because foreign matter is more easily caught than the smooth wall surface. Thereby, since the hole 22a is not formed in the peripheral wall 22 in the vicinity of the stirring blade 8, it is more reliably prevented that foreign matter is caught between the stirring blade 8 and the cutting projection 28 and the peripheral wall 22. .

  As described above, in this embodiment, when the fibrous foreign matter has been washed away, the portion 7a of the rotating shaft 7 as the foreign matter collecting means entangles the foreign matter and is fixed (for example, a lighter). When the foreign matter has been washed away, the foreign matter continues to stay on the stirring blade 8. In this way, in this embodiment, no matter what foreign matter has flowed, the foreign matter does not interfere with the rotation of the stirring blade 8 and the motor 6 does not lock. Even in the storage tank 10, the motor 6 can be driven. Therefore, in this embodiment, the user can continue to use the pressure-feed toilet apparatus 1 until the service staff comes even after the foreign object has been accidentally flushed.

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, and the surrounding wall 22 comprises a part of stirring part 20, it is not restricted to this. The peripheral wall 22 may not be provided. In this case, it is preferable to enlarge the diameter of the stirring blade 8 in accordance with the side wall 11.
