Description

Flush toilet

This invention relates to a flush toilet apparatus, and more particularly to a non-fixed flush toilet apparatus.

Patent Document 1 proposes a non-fixed flush toilet device (pressurized transport toilet device) that is disposed as a care flushing device beside a bed in a living room of a user. In the flushing toilet device, the dirt is pulverized by the agitation of the water flow in the pulverizing portion, and the pulverized dirt is pressurized and transported to the outside by the pressurizing and conveying portion.

In the conventional flush toilet device, even if foreign matter other than dirt or toilet paper (foreign matter that cannot be pulverized) is accidentally washed away, the foreign matter does not remain in the water storage tank, and Since the drive unit such as the electric motor is locked and cannot be used, the user can continue to use the toilet device. In the flush toilet device that is used in the toilet flushing device that is placed next to the bed in the living room, the countermeasure against foreign matter is an extremely important issue that can be commercialized.

In addition, the nursing flushing device disposed beside the bed discharges the finely pulverized dirt through the elongated drain pipe. Department (drainage pipe outside the house), so it is best to use a centrifugal pump that is relatively small, inexpensive and can achieve high lift. However, in order to generate a high pressure, the flow path of the centrifugal pump needs to be narrowed, so that there is a problem that the flow path is blocked if a large amount of dirt or the like flows in.

Therefore, in the toilet device of the patent document 1, only the fine flow pulverized in the pulverization portion by a predetermined size or less is introduced into the pressure transfer portion to prevent clogging of the flow path of the pressure transfer portion.

Patent Document 1: Japanese Patent No. 5549191

On the other hand, in order to form a centrifugal pump which is relatively small and can generate a relatively high pressure, the inventors of the present invention have studied the pressurized conveying as shown in FIG. 7 as a structure in which the flow path is narrowed and the pressure transmitting portion is simple. Part 136.

However, as described above, in the flush toilet device, foreign matter other than dirt and toilet paper may be accidentally washed out, especially like "boxed tissue paper", "flushable wet tissue", and "can be used for facial tissue". The foreign matter such as the "flushable dust-removing cloth" is a foreign matter (a foreign matter that has not been completely pulverized) which is pulverized only in a fibrous state in the pulverizing portion, and such foreign matter has recently been used. Since the fibrous foreign matter is reduced in the state in which the fibrous portion is pulverized in the pulverized portion, it flows into the pressurized transport portion. The fibrous foreign matter flows into the pressurized conveying portion, and is easily caught in the narrow flow of the pressurized conveying portion. In addition, the stuck fibrous foreign matter continuously entangles and grows with the new fibrous foreign matter, and a new problem of clogging the narrow flow path in the pressurized conveying portion is caused.

In particular, as shown in Fig. 7, in order to form a centrifugal pump capable of generating a higher pressure, it is known that the side wall 164 is formed by one vertical wall surface, and the pressure transmitting portion 136 is disposed such that the disk portion 166 is disposed in the vicinity of the side wall 164. With the above new problems, the following problems will arise. In the pressurized conveying unit 136, as shown by the arrows a1 and a2, the collision region 178 which collides with the outer side wall 164 from the radial flow path 174 by the centrifugal force generated by the rotation of the impeller 162 includes a fibrous shape. The dirt of the foreign matter F and the washing water flow from the collision region 178 into the gap 170 formed between the side wall 164 and the disk portion 166.

At this time, the fibrous foreign matter F flows into the gap 170 together with the washing water, and flows into the region B between the disk portion 166 and the pressurized conveying portion 136 as indicated by an arrow a3, because the fibrous foreign matter F is in the region B. The entanglement and growth of each other, so that the disk portion 166, that is, the impeller 162 cannot be rotated, causes the motor to be locked. Further, since the dirt and the washing water further flow into the region C on the outer circumference of the rotating shaft 152, since the fibrous foreign matter F is entangled and grown in the region C, the rotating shaft 152 and the disk portion 166, that is, the impeller 162 cannot be Rotating causes the motor to be locked.

Accordingly, the present invention has been made to solve the above problems, and an object thereof is to provide a flush toilet apparatus using a centrifugal type pressurized conveying unit (such as a centrifugal pump) that can realize a high lift, even if it is washed out in the crushing portion. It can also be smashed into foreign matter until it is in a fibrous state. The fibrous foreign matter is prevented from being entangled and grown between the disk portion and the pressurized conveying portion, so that the disk portion, that is, the impeller cannot be rotated.

In order to achieve the above object, the present invention is a flush toilet device which is a non-fixed flush toilet device, comprising: a toilet body; a water supply unit that supplies washing water to the toilet body; and the crushing is performed together with the washing water from the toilet body a pulverizing portion that discharges the dirt; a pressurized conveying portion that sucks the dirt and the washing water pulverized by the pulverizing portion; and discharges the dirt and the washing water pressurized by the pressurized conveying portion to the outside And a flexible drain pipe; and a passage between the pulverizing portion and the pressurizing and conveying portion, and the pulverized portion is pulverized by a predetermined size or less, and is transported to the passage regulating portion of the pressurized conveying portion. The pressure conveying unit is a centrifugal type pressure conveying unit including an impeller, an inflow port, an outflow port, a radial flow path, and a circumferential flow path, and the impeller is disposed inside the side wall of the pressurizing conveying unit and rotates in the pressurized conveying unit. The impeller includes a disk-shaped disk portion and a protruding portion that is provided to protrude from the disk portion, the inflow port is formed at a central portion of the pressurizing transport portion, and the outflow port is formed at an outer peripheral portion of the pressurizing transport portion. The flow path is formed between the protrusions and communicates with the inflow port and extends toward the outer circumference. The circumferential flow path extends in the circumferential direction on the outer circumference of the impeller and communicates with the outflow port, and the side wall of the pressurized conveying portion is provided by the impeller The centrifugal force generated by the rotation causes the collision between the dirt flowing from the radial flow path to the circumferential flow path and the collision of the side wall where the cleaning water collides with the gap formed between the side wall and the disk portion, and the dirt and cleaning It is difficult for water to flow from the collision region into the restriction portion of the gap portion.

In the present invention configured as described above, if foreign matter such as "boxed tissue" or "squeezable wet tissue" is washed out from the toilet body, the pulverized portion is pulverized into a fibrous shape and flows into the pressurized conveyance. unit. The fibrous foreign matter that has flowed into the pressurized conveying portion from the inflow port and the washing water flow from the radial flow path to the outer circumferential flow path by the centrifugal force generated by the rotation of the impeller. When the dirt and the washing water in the collision region from the radial flow path collide with the outer side wall flow from the collision region into the gap formed between the side wall and the disk portion, the fibrous foreign matter flows into the gap together with the washing water due to Since the fibrous foreign matter is entangled and grown between the disk portion and the pressurized conveying portion, the disk portion, that is, the impeller cannot be rotated, and the motor is locked. However, according to the flush toilet device of the present embodiment, the side wall of the pressurizing and conveying portion is provided with dirt that flows from the radial flow path to the circumferential flow path by the centrifugal force generated by the rotation of the impeller and collides with the collision region of the side wall. Since it is difficult for the washing water to flow into the restricting portion of the gap portion from the collision region, it is possible to prevent the fibrous foreign matter from being entangled and grown between the disk portion and the pressurized conveying portion, so that the disk portion, that is, the impeller cannot be rotated and the motor is locked. The problem of living.

In the present invention, it is preferable that the side wall of the pressurizing conveyance portion includes an outer side wall having a collision region; and an inner side wall formed on the inner side in the radial direction from the outer side wall, and the gap portion is formed on the inner side wall and the disc portion The restricting portion extends inward in the radial direction of the pressurizing conveying portion and connects the outer side wall and the inner side wall.

In the present invention configured as described above, since the gap portion is formed between the inner side wall and the disk portion, it is difficult for the dirt and the washing water that collide with the collision region of the outer side wall to flow from the collision region to the radial direction against the centrifugal force. On the inner side, it is possible to make it difficult to flow into a gap portion formed on the inner side in the radial direction from the collision region.

In the present invention, it is preferable that the restricting portion is provided at a position apart from the radial flow path on the radial flow path side of the disk portion by a predetermined distance in the height direction, and the gap portion is provided on the radial flow path side from the disk portion. The radial flow path is away from the specified distance in the height direction.

In the present invention configured as described above, the restricting portion is provided at a position away from the predetermined distance by the flow of the dirt and the washing water flowing from the radial flow path to the circumferential flow path and the collision region in the height direction. Further, the gap portion provided on the inner side wall to which the restricting portion is connected is also a position that is disposed at a predetermined distance in the height direction from the flow of the dirt and the washing water flowing from the radial flow path to the circumferential flow path and the collision area. Therefore, it is possible to more reliably suppress the dirt flowing into the circumferential flow path from the radial flow path of the radial flow path and the washing water from flowing into the gap portion before colliding with the collision region.

In the present invention, it is preferable to further include: a common rotary drive shaft extending between at least the pulverizing portion and the pressurized conveying portion, and transmitting a driving force for agitating the washing water in the pulverizing portion from the driving source and conveying the pressure a driving force for rotating the impeller in the portion; a flow path around the rotating shaft, the communicating portion and the pressurized conveying portion, and a part of which is formed on an outer peripheral surface of the common rotational driving shaft between the crushing portion and the pressurized conveying portion; And another portion is formed between the disk portion and the pressurized conveying portion.

In the present invention, the common rotating shaft is disposed between the pulverizing portion and the pressurized conveying portion, and the flow path around the rotating shaft such as the wear of the common rotating drive shaft is reduced to pass the common rotation. drive The outer peripheral surface of the shaft is formed, and the fibrous foreign matter and the washing water can flow together to form a part of the outer peripheral surface of the common rotary drive shaft and the other part of the rotary shaft formed between the disc portion and the pressurized conveying portion. In the case of the structure of the surrounding flow path, since it is possible to prevent the dirt and the washing water that collide with the collision region of the side wall from flowing into the gap portion from the collision region, it is possible to prevent the fibrous foreign matter from being pressed in the disk portion and the pressurizing portion. The rotating portions of the conveying portions and/or the common rotating drive shaft are entangled with each other and grow, so that the disk portion, that is, the impeller cannot rotate and the motor is locked.

According to the flush toilet device of the present invention, even when a centrifugally pressurized conveying unit (such as a centrifugal pump) that can realize a high lift is used, and a foreign matter that can only be pulverized into a fibrous state in the pulverizing portion is washed out, It is also possible to prevent the fibrous foreign matter from being entangled and grown between the disk portion and the pressurized conveying portion, so that the disk portion, that is, the impeller cannot be rotated.

Next, the pulverizing and pressing conveying device 4 of the flush toilet device 1 will be described with reference to Figs. 3 to 7 . 3 is a cross-sectional view showing a pulverizing and conveying device of a flush toilet device according to an embodiment of the present invention, and FIG. 4 is an enlarged cross-sectional view showing a pressurizing and conveying portion of the pulverizing and pressing conveying device, and FIG. 5 is obliquely downward. The external view of the state of the pressurization conveyance part of the pressurization conveyance part of the pulverization-pressure-conveying apparatus which the detachment of the lower cover has been observed, and FIG. FIG. 7 is a schematic view showing the flow of the dirt and the washing water in the pressure transfer chamber, and FIG. 7 is a view showing the dirt and the washing water in the pressurized transfer chamber of the pressurizing and conveying portion of the pulverizing and conveying device of the conventional flush toilet device. A schematic diagram of the flow.

As shown in Fig. 3, the pulverizing and pressing conveying device 4 is connected to the discharge port 32 of the discharge water trap conduit 26 of the above-described toilet body 2, and the dirt flows therein together with the washing water.

The pulverizing and conveying device 4 includes a storage tank 46, and a pulverizing portion 34 is provided inside the storage tank 46. The pulverizing portion 34 has a pulverizing chamber 48 formed inside the peripheral wall 48a. The peripheral wall 48a of the pulverizing chamber 48 communicates with the discharge port 32 of the above-described discharge water trap conduit 26 on one side thereof. A disc 50 for agitating the dirt in the pulverizing chamber 48 is provided at a lower portion of the pulverizing chamber 48. The disk 50 is directly coupled to a rotating shaft 52 (common rotating drive shaft) attached to the electric motor 38 and is rotatable. And, in the disc A plurality of protrusions 50a are formed on the upper surface of the 50, and dirt is caught on the protrusions 50a and becomes easily stirred.

Specifically, the arrow in Fig. 3 indicates the flow state of the dirt and the washing water. From the arrow, it is understood that the dirt dropped onto the disk 50 moves toward the outer peripheral side together with the washing water due to the rotation of the disk 50. The collision rises along the peripheral wall 48a after the peripheral wall 48a, and descends on the disk 50 while moving toward the inner peripheral side. The dirt is stirred and pulverized while rotating in the vertical direction as described above. In this way, the pulverizing unit 34 constitutes a pulverizing unit of a water flow decomposition type in which the water is generated by agitating the stored washing water while storing the washing water to decompose the dirt. Further, the pulverizing portion 34 may be a pulverizing portion that physically pulverizes dirt by a blade such as a cutter.

As shown in Fig. 3, a plurality of passage openings 48b (through the restricting portions) having a predetermined size are formed in the vicinity of the outer peripheral side of the disk 50 of the peripheral wall 48a. Because of these passage openings 48b, only the dirt pulverized by a predetermined size can pass through the peripheral wall 48a, and on the other hand, the dirt larger than a predetermined size can be restricted from passing.

Next, the pressurized conveying unit 36 of the pulverizing and pressing conveying device 4 will be described in detail based on FIGS. 4 to 6 .

The impeller 62 includes a disk portion 66 having a disk shape and a projection portion 68 that is provided to protrude downward from the disk portion.

The disk portion 66 is disposed above the inner side of the side wall 64 of the pump chamber 56 so as to be substantially horizontal. The disk portion 66 is coupled to the lower end of the rotating shaft 52 and is rotated by the electric motor 38. The rotating shaft 52 extends at least between the pulverizing portion 34 and the pressure transmitting portion 36, and serves as a driving force for transmitting the disk 50 for agitating the washing water in the pulverizing portion 34 from the electric motor 38 (driving source) and at the pressurizing conveying portion. In 36, a common rotational driving shaft for driving the disk portion 66 of the impeller 62 is formed.

Side 66c. As will be described later, the disk side surface 66c of the disk portion 66 is slightly separated from the inner side wall 64b of the pump chamber 56, and the gap portion 70 is formed. Further, the crushing portion side surface 66a of the disk portion 66 is slightly separated from the upper surface 56a of the pump chamber 56, and a gap flow path 82c is formed. Thus, the disk portion 66 can be driven to rotate with respect to the upper surface 56a of the pump chamber 56. Further, the gap flow path 82c forms a relatively narrow flow path between the pulverizing portion side surface 66a and the upper surface 56a.

The two projections 68 of the impeller 62, that is, the two blade portions have the same shape, and are arranged in point symmetry in plan view, and the inner wall surface 68a of each of the projections 68 is formed to extend radially outward from the center portion around the inlet 58.

In addition, two protrusions on the impeller 62 Between the outer peripheral side wall surface 68b of each of the rising portions 68 and the side wall 64 of the pump chamber 56, a circumferential flow path 76 extending in the circumferential direction is formed, and the upstream ends of the circumferential flow paths 76 communicate with the radial flow paths 74, respectively. The end is connected to the outflow port 60 of the pump chamber 56.

In the radial flow path 74, the dirt and the washing water are relatively strongly pushed outward from the center portion by the centrifugal force generated by the rotation of the impeller 62, and a relatively strong flow is formed toward the outside. Here, in the present embodiment, the entire two radial flow paths 74 formed by the two projections 68 of the pressurizing and conveying portion 36 are formed as a single flow path that extends substantially linearly. As a modification, the radial flow path 74 of the impeller 62 may be a different shape or a number of radial flow paths formed by protrusions of different shapes and numbers, and may be formed, for example, by three protrusions. The three radial flow paths may be four radial flow paths formed by four protrusions, or may be a plurality of radial flow paths formed by a plurality of protrusions.

In the present embodiment, the impeller 62 that rotates in the pump chamber 56 of the pressurizing and conveying unit 36 includes a disk portion 66 that is provided above the pump chamber 56 and that is attached to the rotating shaft 52 that extends upward; The protrusion 68 that protrudes downward from the disk portion 66 is provided. However, in the flush toilet device of another embodiment, the impeller that rotates in the pump chamber of the pressure transfer unit may be provided in the pump chamber. The lower portion is attached to a disk portion of a rotating shaft extending downward; and a structure provided with a protruding portion that protrudes upward from the disk portion.

Next, the restricting portion and the gap portion of the pressurizing and conveying portion 36 of the pulverizing and conveying device 4 will be described in detail based on FIGS. 4 to 6 . Bright.

The collision region 78 is formed between the gap portion 70 formed between the side wall 64 and the disk portion 66, and it is difficult for the dirt and the washing water to flow into the restricting portion 80 of the gap portion 70 from the collision region 78.

The side wall 64 of the pump chamber 56 of the pressurizing conveying portion 36 is provided with an outer side wall 64a that forms a longitudinal wall surface of a side portion of the pump chamber 56 that faces the outlet of the radial flow path 74, and is disposed closer to the outer side wall 64a. The inner side wall 64b of the longitudinal wall surface of the side portion of the pump chamber 56 opposite to a portion of the disc side surface 66c of the disk portion 66 is formed on the inner side in the radial direction.

The lower portion of the outer side wall 64a is connected to the lower cover 57, and the upper portion thereof is connected to the restricting portion 80. The outer side wall 64a is formed on the outer side in the radial direction of the radial flow path 74 and the outer side in the radial direction of the circumferential flow path 76. As shown in FIGS. 4 and 6 , the outer side wall 64 a is formed to have a height larger than the height of the radial flow path 74 , and is formed to cover the radially outer side of the radial flow path 74 in the horizontal direction.

The outer side wall 64a has a collision area 78 where the dirt and the washing water collide with each other from the radial flow path 74 to the circumferential flow path 76 by the centrifugal force generated by the rotation of the impeller 62. In such a collision region 78, since the washing water flowing straight from the center of the impeller 62 to the outer side in the radial direction maintains its flow and collides with the outer side wall 64a as if it is pressed, when the dirt and the washing water collide, Water pressure is formed in the conflict zone 78 The state of a relatively high area. Therefore, the dirt and the washing water form a flow that is diffused not only in the circumferential direction but also in the height direction from the region where the water pressure is relatively high toward the relatively low surrounding region. The flow from the collision region 78 to the gap portion 70 among the flow of the diffusion can be restricted by the restriction portion 80.

The lower portion of the inner side wall 64b is connected to the restricting portion 80, and the upper portion thereof is connected to the upper surface 56a of the pump chamber 56. The lower end 64c of the inner side wall 64b is disposed between the crushing portion side surface 66a of the disk portion 66 and the radial flow path 66b. The lower end 64c of the inner side wall 64b is provided at a position separated from the radial flow path 66b on the radial flow path side of the disk portion 66 by a predetermined distance D1 in the height direction.

The restricting portion 80 is provided between the upper end 64d of the outer side wall 64a and the lower end 64c of the inner side wall 64b to connect the outer side wall 64a and the inner side wall 64b. The restricting portion 80 forms a step portion extending radially inward from the outer side wall 64a between the outer side wall 64a and the inner side wall 64b. More specifically, the restricting portion 80 is formed to extend in a horizontal direction substantially at right angles to the outer side wall 64a and the inner side wall 64b extending substantially perpendicularly.

The restricting portion 80 is disposed on the side wall 64 of the pump chamber 56 to prevent linear flow paths that can linearly connect the collision region 78 and the gap portion 70 on the same plane, and/or to avoid forming a collision region that can be linearly connected on the same plane. 78 is a linear flow path with the gap portion 70. In other words, the restricting portion 80 suppresses and/or restricts the washing water flowing (diffusing) along the outer side wall 64a among the dirt and the washing water that collides with the conflicting region 78, along the same An extension line of a substantially linear flow direction on the plane flows into the gap portion 70. A step portion or the like is formed in the restricting portion 80 so as to restrict the dirt and the washing water diffused from the relatively high pressure region in the vicinity of the collision region 78 from flowing directly into the gap portion 70 along the same plane. The restricting portion 80 is capable of changing the flow of dirt and washing water that hits itself and weakens the flow. The restricting portion 80 is disposed at a position higher than the collision region 78 on the outer side in the radial direction of the flow path in the radial flow path 74. In other words, the restricting portion 80 is disposed on the outer side in the height direction of the collision region 78 and on the disk portion 66 side. The restricting portion 80 is provided at a position separated from the radial flow path 66b on the radial flow path side of the disk portion 66 by a predetermined distance D1 in the height direction.

The gap portion 70 is formed between the inner side wall 64b connected to the inner side of the restricting portion 80 and the disk portion 66, and the gap portion 70 is provided in the height direction from the radial flow path surface 66b on the radial flow path side of the disk portion 66. Distance to the location of D1.

These predetermined distances D1 are set such that the water flow of the washing water or the like flowing out from the radial flow path 74 on the radial flow path 66b is supposed to spread upward, and the water flow does not directly flow into the gap portion 70, or It collides with the lower end 64c of the inner side wall 64b.

In order to reduce the size of the pump and improve the performance of the pump, the disc side surface 66c is disposed close to the inner wall surface 68a, and the gap portion 70 is formed with a relatively small gap size. In the cross section shown in Fig. 6, the flow path width of the gap portion 70 is in the range of 0.5 mm to 20 mm.

Further, the pulverizing and conveying device 4 includes a rotating shaft peripheral flow path 82 that communicates with the pulverizing portion 34 and the pressurized conveying portion 36, and has a partial shape The other peripheral portion of the rotating shaft 52 that passes through the common portion between the crushing portion 34 and the pressurized conveying portion 36 is formed between the disk portion 66 and the pressurized conveying portion 36.

A pressurizing transport unit 36 is provided at a lower portion of the pulverizing chamber 48 of the pulverizing unit 34. The rotating shaft 52 extends from the electric motor 38 through the pulverizing unit 34 and extends inside the pressurizing transport unit 36. The rotating shaft 52 is attached to the disk 50 in the pulverizing portion 34, and is attached to the disk portion 66 in the pressurized conveying portion 36.

In the back side (lower side) of the disk 50 at the lower portion of the pulverization chamber 48, a pulverization chamber lower flow path 82a is formed between the disk 50 and the pulverization chamber 48. Since the crushing chamber lower flow path 82a is formed, the disk 50 can be driven to rotate without contacting the bottom surface of the crushing chamber 48. An opening portion 84 is formed in the vicinity of the center in the radial direction between the pulverizing portion 34 and the pressure transmitting portion 36. A rotating shaft 52 is disposed at the center of the opening portion 84. In the opening portion 84, a peripheral region on the outer peripheral surface of the rotating shaft 52 forms an outer peripheral surface flow path 82b. In this way, since the outer peripheral surface flow path 82b which passes through the outer peripheral surface of the rotating shaft 52 is formed, the wear of the common rotating shaft 52 and the like, and/or the frictional resistance (rotational resistance) of the rotating shaft 52 can be reduced.

Further, in the portion of the flow path 82 around the rotating shaft 82 formed in the gap flow path 82c between the disk portion 66 and the pressurized conveying portion 36, since the gap flow path 82c is formed, the disk portion 66 can be prevented from contacting the pump. The upper surface 56a of the chamber 56 is driven to rotate.

In this way, the flow path 82 around the rotating shaft forms a flow path from the crushing chamber lower flow path 82a on the back side (lower side) of the disk 50 through a slight gap between the crushing chamber 48 and the disk 50, and the image is rotated by the image. The outer peripheral surface flow path 82b on the outer circumferential surface of the shaft 52 reaches the gap portion 70 through the gap flow path 82c formed between the disk portion 66 and the pressure transfer portion 36. The dirt and the washing water can flow into the pressurizing and conveying unit 36 from the crushing chamber 48 through the rotating shaft surrounding flow path 82, and can flow into the crushing chamber 48 from the pressurizing and conveying unit 36 through the rotating shaft surrounding flow path 82. Further, since a small gap between the pulverizing chamber 48 and the disk 50 forms a very small gap (a smaller gap than the opening 48b), dirt larger than a predetermined size does not flow into the flow path 82 around the rotating shaft, Further, the flow rate of the dirt and the washing water flowing through the flow path 82 around the rotating shaft is restricted to be extremely small compared to the flow rate flowing through the flow path 54.

Further, in the present embodiment, the inner side wall 64b is disposed closer to the inner side in the radial direction than the outer side wall 64a, the restricting portion 80 extends inward in the radial direction, and the gap portion 70 is formed closer to the radial direction than the collision region 78. Different walls on the inside.

On the other hand, in another embodiment, the side wall of the pump chamber is not formed on the respective planes of the inner side wall and the outer side wall, but the side wall is formed as a longitudinal wall surface from the lower end to the upper end of the pump chamber, and therefore, the gap portion is Conflict zones may be arranged on the same wall. At this time, between the gap portion and the collision region, the restricting portion may be formed as a protruding portion or a convex portion that protrudes inward from the side wall. That is, on the side wall of the pump chamber, the restricting portion is disposed to prevent the flow paths of the collision region and the gap portion from being linearly connected on the same plane. In other words, since the flow of the dirt and the washing water flowing from the collision region to the gap portion collides with the restricting portion, it becomes difficult to flow into the gap portion. Thus, in other embodiments, the side wall is also provided by: The centrifugal force generated by the rotation flows from the radial flow path to the circumferential flow path, and the conflicting region of the side wall where the dirt and the washing water collide with each other and the gap portion formed between the side wall and the disk portion, and the dirt and the washing water It is difficult to flow into the restriction portion of the gap portion from the collision region.

Next, the operation (operation) of the above-described flush toilet device according to the embodiment of the present invention will be described with reference to FIGS. 2 to 6 . In Figs. 2 to 6, each arrow indicates the flow state of the dirt and the washing water.

First, the user operates the operation switch of the operation unit 40 to clean the toilet body 2 with the washing water, thereby starting the washing operation. When an operation switch or the like of the operation unit 40 is operated, the operation command is transmitted to the control unit 44, and the control unit 44 transmits a water supply command to the water supply device 24 based on the command, and performs water supply from the water supply device 24 to the bowl portion 22 for a predetermined period of time. Thereby cleaning the toilet body 2. Further, an operation command is transmitted from the control unit 44 to the electric motor 38, and the electric motor 38 starts the rotation operation.

The dirt and the washing water are discharged from the discharge water trap conduit 26 by the drop of the washing water, flow into the crushing chamber 48 of the crushing and pressure conveying device 4 through the discharge port 32, and descend to the disk 50. In the pulverization chamber 48, the disk 50 has been rotated, and the dirt dropped onto the disk 50 moves toward the outer peripheral side together with the washing water by the rotation of the disk 50, and rises along the peripheral wall 48a after colliding with the peripheral wall 48a. In addition, it is lowered while moving toward the inner peripheral side, and is stirred and pulverized while rotating in the vertical direction (see FIG. 3).

Then, as shown in FIG. 3 and FIG. 4, a plurality of passage openings 48b having a predetermined size are formed in the vicinity of the outer peripheral side of the disk 50 of the peripheral wall 48a, and therefore the dirt is pulverized in the pulverization chamber 48. The dirt smaller than the size passing through the opening 48b is discharged from the passage 48b passing through the opening 48b to the downstream side. Further, the dirt larger than the size of the passage opening 48b is continuously stirred and pulverized in the vertical direction in the pulverization chamber 48 until the predetermined size is equal to or smaller than the predetermined size.

The pulverized dirt flows into the pump chamber 56 from the inflow port 58 formed at the central portion of the lower surface of the pump chamber 56 of the pressurizing and conveying portion 36 through the flow path 54 together with the washing water. As shown in Fig. 6, the dirt flowing into the pump chamber 56 and the washing water flow into the radial flow path 74 formed between the projections 68, as indicated by an arrow A1, from the center of the pump chamber 56 by the impeller. The centrifugal force generated by the rotation of 62 flows from the radial flow path 74 to the circumferential flow path 76. In addition, the dirt and the washing water pushed from the radial flow path 74 to the outer circumferential side of the circumferential flow path 76 by the centrifugal force collide with the collision region 78 of the side wall 64 while maintaining the flow potential and direction. As indicated by the arrow A2, the dirt and the washing water that collide with the collision region 78 form a flow that is diffused from the collision region 78 not only in the circumferential direction but also in the height direction. A relatively strong flow of the dirt and the cleaning water to the outflow port 60 is formed in the circumferential flow path 76, and the flow that is diffused in the circumferential direction from the collision region 78 becomes a flow toward the outflow port 60. On the other hand, as indicated by an arrow A2, there is a flow that is vertically diffused from the collision region 78 in the height direction.

Here, the flow of the dirt and the washing water to be diffused up and down from the collision region 78 in the height direction flows along the outer side wall 64a, and conflicts. In the restriction portion 80. As indicated by an arrow A3 in Fig. 5, the water flow colliding with the restricting portion 80 flows in the direction of the outflow port 60 of the circumferential flow path 76 (the direction toward the front side or the back side in Fig. 6). The restricting portion 80 suppresses and/or restricts the dirt that has collided with the collision region 78 and the washing water that is intended to flow along the outer side wall 64a among the washing water flows into the gap portion 70 along a substantially linear water flow on the same plane. In addition, even in the vicinity of the restricting portion 80, most of the flow flows outward in the radial direction by the centrifugal force generated by the rotation of the impeller 62, and it is difficult to form a flow that flows inward in the radial direction against the centrifugal force. Therefore, it is difficult for the dirt and the washing water reaching the restricting portion 80 to flow to the gap portion 70. Therefore, as shown in Fig. 6, it is possible to prevent the fibrous foreign matter F in the dirt from flowing into the gap portion 70 from the collision region 78, and it is possible to prevent the fibrous foreign matter F from being entangled between the disk portion 66 and the pump chamber 56. And growing, the disk portion 66, that is, the impeller 62, cannot be rotated and the motor is locked.

Further, the restricting portion 80 is provided at a position where the dirt and the washing water flowing from the radial flow path 66b to the circumferential flow path 76 and the collision region 78 are separated by a predetermined distance D1 in the height direction. Further, the gap portion 70 provided in the inner side wall 64b to which the restricting portion 80 is connected is also provided in the height direction from the dirt and the washing water flowing from the radial flow path 66b to the circumferential flow path 76 and the collision area 78. Distance to the location of D1. Therefore, it is possible to more reliably prevent the dirt and the washing water flowing from the radial flow path surface 66b of the radial flow path 74 to the circumferential flow path 76 from directly flowing into the gap portion 70 before colliding with the collision region 78, or colliding with the lower end of the inner side wall 64b. 64c.

As shown in Fig. 6, in the flow path 82 around the rotating shaft, since it is difficult for the dirt and the washing water to flow into the gap portion 70, the water flow of the washing water flowing from the gap portion 70 to the gap flow path 82c is not formed. Therefore, as shown by the arrow A4, the dirt and the washing water form a flow from the crushing chamber 48 to the gap portion 70 through the crushing chamber lower flow path 82a, the outer peripheral surface flow path 82b, and the gap flow path 82c, or in the flow path. The washing water is in a state of being substantially retained.

Further, in the flow path 82 around the rotating shaft, since the washing water can flow between the crushing portion 34 and the pressurized conveying portion 36, the gap flow path 82c formed between the disk portion 66 and the pressurized conveying portion 36 serves as a stain. The object and the part of the flow path of the flow path 82 around the rotating shaft through which the washing water can flow are formed, and the technical meaning is different from the fixed gap between the conventional disk portion 66 and the pressurized conveying portion 36. In the flush type toilet device of the non-fixed type, the rotating shaft around which the pulverizing portion 34 and the pressurized conveying portion 36 are commonly driven is driven such that the rotating shaft surrounding passage 82 is provided as a unique flow path. Further, the problem that the fibrous foreign matter and the washing water flow in the flow path 82 around the rotating shaft also poses a problem inherent to the non-fixed flush toilet device.

Thereafter, the dirt and the washing water in the pump chamber 56 are discharged from the outflow port 60. The dirt and the washing water discharged by the pressurized conveying unit 36 are discharged to the outdoor drain pipe 20 through the indoor drain pipe 8, and the discharge operation of the dirt is ended.

Next, the operation and effect of the above-described flush toilet device 1 of the present embodiment will be described.

First, in the flush toilet device 1 of the present embodiment, when foreign matter such as "boxed tissue paper" or "smokable wet tissue" is washed out to the toilet body 2, it is pulverized in the pulverizing portion 34. The fiber flows into the pressurized conveying portion 36. The fibrous foreign matter F and the washing water flowing into the pressurizing and conveying portion 36 from the inflow port 58 flow from the radial flow path 74 to the outer circumferential flow path 76 by the centrifugal force generated by the rotation of the impeller 62. When the dirt and washing water colliding from the collision region 78 of the side wall 64 of the outer side from the radial flow path 74 flow from the collision region 78 into the gap formed between the side wall 64 and the disk portion 66, the fibrous foreign matter F and the cleaning The water flows into the gap together, and since the fibrous foreign matter F is entangled and grown between the disk portion 66 and the pressurized conveying portion 36, the disk portion 66 is generated, that is, the impeller 62 cannot be rotated and the motor is locked. .

However, according to the flush toilet device 1 of the present embodiment, the side wall of the pressurizing and conveying unit 36 is provided with the centrifugal force generated by the rotation of the impeller 62, and flows from the radial flow path 74 to the circumferential flow path 76 and collides with the side wall 64. The dirt and the washing water in the collision region 78 are less likely to flow into the restricting portion 80 of the gap portion 70 from the collision region 78. Therefore, it is possible to prevent the fibrous foreign matter F from being entangled and grown between the disk portion 66 and the pressurizing transport portion 36. Thus, the disk portion 66, that is, the impeller 62, cannot be rotated and the motor is locked.

Further, according to the flush toilet device 1 of the present embodiment, since the gap portion 70 is formed between the inner side wall 64b and the disk portion 66, it is difficult for the dirt and the washing water that collide with the collision region 78 of the outer side wall 64a to collide with the conflict. The region 78 flows inward in the radial direction against the centrifugal force, so that it is difficult to flow in and is formed closer to the radius than the collision region 78. The gap portion 70 on the inner side.

Further, according to the flush toilet device 1 of the present embodiment, the restricting portion 80 is provided at a predetermined distance from the flow of the dirt and the washing water flowing from the radial flow path 66b to the circumferential flow path 76 and the collision area 78 in the height direction. position. Further, the gap portion 70 provided in the inner side wall 64b to which the restricting portion 80 is connected is also provided in the height direction from the flow of the dirt and the washing water flowing from the radial flow path 66b to the circumferential flow path 76 and the collision area 78. Leave the location of the specified distance. Therefore, it is possible to more reliably suppress the dirt and the washing water flowing from the radial flow path surface 66b of the radial flow path 74 to the circumferential flow path 76 from flowing into the gap portion 70 before colliding with the collision region 78.

In addition, the flushing toilet device 1 of the present embodiment has a common rotating shaft 52 disposed between the crushing unit 34 and the pressurizing and conveying unit 36, and reduces the wear of the common rotating shaft 52 or the like around the rotating shaft. The flow path 82 is formed so as to pass through the outer peripheral surface of the common rotating shaft 52, and the fibrous foreign matter F can flow into a part of the outer peripheral surface of the common rotating shaft 52 and the other part is formed in the disk part together with the washing water. In the case of the configuration of the gap flow path 82c between the 66 and the pressurizing transport unit 36, the restricting portion 80 that makes it difficult for the dirt and the washing water that collides with the collision region 78 of the side wall 64 to flow into the gap portion 70 from the collision region 78 is provided. Therefore, it is also possible to prevent the fibrous foreign matter F from being entangled and grown between the disk portion 66 and the pressure transmitting portion 36 and/or the common rotating shaft 52, so that the disk portion 66, that is, the impeller 62 cannot be rotated and the motor is Locked.
