Hereinafter, embodiments of the pumping toilet of the present invention will be described in detail with reference to the accompanying drawings. The present invention is not limited to the embodiments shown below.

FIG. 1 is a schematic view showing a pumping toilet according to the present invention. As shown in FIG. 1, the pumping toilet 1 according to the embodiment includes a toilet TB, a storage tank 10, a crushing section 20, an opening 14, a pumping section 30, a discharge port 60, a prevention section 40, and a water level. It includes a detection unit 80 and an operation unit 90.

The toilet bowl TB includes a water supply pipe 4 that supplies wash water to the toilet bowl TB, and an on-off valve 3 that opens and closes the water supply pipe 4. The wash water is supplied to the toilet bowl TB via the water supply pipe 4 when the on-off valve 3 is opened by the control unit 70.

The storage tank 10 is connected to the toilet bowl TB by the connecting pipe 100. The filth F (see FIG. 4) in the toilet bowl TB and the washing water supplied from the water supply pipe 4 flow into the storage tank 10 via the connecting pipe 100. Further, the storage tank 10 stores wash water and filth F (for example, excrement and toilet paper).

The crushing unit 20 is provided inside the storage tank 10 and crushes the filth F that has flowed into the storage tank 10. The outer wall 11 of the crushing portion is provided with an opening 14 for discharging the washing water and the filth F that have flowed into the storage tank to the downstream side. The crushing unit 20 further includes a rotating unit 21 and a driving means 50 (for example, a motor). The driving means 50 is driven by the control unit 70 to rotate the rotating unit 21. The crushing unit 20 agitates the washing water and the filth F stored in the storage tank 10 so that the filth F collides with the outer wall 11 of the crushing unit 20 and is crushed. The filth F is crushed by the crushing unit 20 until it becomes smaller than the diameter of the opening 14, and when it becomes smaller than the diameter of the opening 14, it flows out from the opening 14.

The pressure feeding unit 30 is provided on the downstream side of the opening 14, pressurizes the filth F that has passed through the opening 14, and sends it to the discharge port 60. The discharge port 60 discharges the filth F to the outside of the pumping toilet 1.

The water level detection unit 80 is provided inside the storage tank 10, detects the water level inside the storage tank 10, and transmits the water level information to the control unit 70.

The operation unit 90 is operated when the user wants to supply the wash water to the toilet bowl TB, and when the operation unit 90 is operated by the user, the wash water is supplied to the toilet bowl TB.

As described above, the pumping toilet 1 according to the embodiment is larger than the storage tank 10 by crushing the filth F into a predetermined size, specifically, a size smaller than the opening 14 and discharging it from the discharge port 60. It is possible to prevent clogging of filth with the piping on the downstream side.

However, foreign matter having an elongated shape such as a hairpin or a toothpick may be mixed in the storage tank 10 and the crushing portion 20. Even if the foreign matter can pass through the opening 14, it cannot pass through the bent pipe portion, which may induce clogging of the pipe.

Therefore, in the pumping toilet 1 according to the embodiment, a prevention unit 40 for preventing the outflow of foreign matter mixed in the storage tank 10 and the crushing unit 20 from the crushing unit 20 is provided on the downstream side of the opening 14 and on the upstream side of the discharge port 60. I decided. As a result, it is possible to prevent the pipe from being clogged even when a slender foreign matter is mixed in.

Next, the control unit 70 of the pumping toilet 1 described above will be described. FIG. 2 is a diagram showing a signal of the control unit 70 of the pumping toilet according to the embodiment.

As shown in FIG. 2, the control unit 70 is connected to the on-off valve 3, the pumping unit 30, the driving means 50, the water level detection unit 80, the operation unit 90, and the notification unit 95. When operated by the user, the operation unit 90 transmits the operated information to the control unit 70. The notification unit 95 notifies the state of the pumping toilet 1 and the like.

The water level detection unit 80 transmits the water level information inside the storage tank 10 to the control unit 70. Alternatively, the water level detection unit 80 detects the water level inside the storage tank 10 according to the command of the control unit 70.

When the control unit 70 supplies the wash water to the toilet bowl TB, the control unit 70 transmits an open / close signal to the on-off valve 3 to supply the wash water to the toilet bowl TB.

When the washing water and the filth F flow into the inside of the storage tank 10, the control unit 70 transmits a signal to the drive means 50 to start the operation of crushing the filth F, and drives the drive means 50. Similarly, when the washing water and the filth F flow into the inside of the storage tank 10, a signal is transmitted to the pumping unit 30 to discharge the washing water and the filth F to the outside of the pumping toilet 1 to drive the pumping unit 30.

Next, a specific configuration of the pumping toilet 1 described above will be described. FIG. 3 is a cross-sectional view of the pumping toilet 1 according to the embodiment. Further, FIG. 4 is a diagram schematically showing the flow of the washing water and the filth F in the pumping toilet 1 according to the embodiment.

As shown in FIG. 3, the water level detection unit 80 is provided inside the storage tank 10 and is provided below the connecting pipe 100. The crushing portion 20 has a cylindrical outer wall 11. The outer wall 11 has a peripheral wall 12 having a wall surface in the circumferential direction of the crushing portion 20, and a bottom wall 13 (see FIG. 1) connected to the peripheral wall 12 on the lower side of the crushing portion 20. The peripheral wall 12 and the bottom wall 13 form a cylindrical crushed portion 10, and it is possible to store filth F and washing water.

A plurality of openings 14 are formed in the lower portion of the peripheral wall 12 to discharge the filth F crushed by the crushing portion 20 to the downstream side of the crushing portion 20. Each opening 14 is assumed to be circular, but does not necessarily have to be a perfect circle and may be elliptical. By discharging only the filth F smaller than the diameter of the opening 14 to the downstream side of the crushing portion 20, it is possible to prevent the filth from being clogged on the downstream side of the crushing portion 20.

The crushing unit 20 has a connecting unit 17 with a connecting pipe 100 (see FIG. 1). The connecting portion 17 is an opening formed from the upper portion to the central portion of the peripheral wall 12, and is closed by the lid portion 101 described later in the used state. The plurality of openings 14 are formed below the connecting portion 17. Further, the crushing portion 20 has a mounting portion 18 for mounting the prevention portion 40. The mounting portion 18 has, for example, a protruding portion 18a and a screw 18b. The protruding portion 18a is a member projecting from the peripheral wall 12 and has a screw hole at the tip thereof. The screw 18b is screwed into the screw hole of the protrusion 18a.

The rotating portion 21 is provided in the vicinity of the bottom wall 13, and is formed in a circular shape when the rotating portion 21 is viewed from above the paper surface (that is, along the axial direction of the drive shaft 51). Further, the rotating portion 21 is connected to the driving means 50 (for example, a motor) via the driving shaft 51 in order to rotationally drive the rotating portion 21 formed in a circular shape. The driving means 50 is provided above the storage tank 10.

The flow path 15 on the downstream side of the opening 14 includes a peripheral wall 12 of the crushing section 20, an outer wall (peripheral wall and bottom wall) of the pumping section 30, and a storage tank 10 arranged so as to surround the crushing section 20 and the pumping section 30. The gap provided between the two is the flow path 15. The flow path 15 is a first region A, which is a region of the feed flow path 15 on the peripheral wall 12 of the crushing portion 20, and a region on the downstream side of the first region A, in a direction along the bottom wall of the pumping portion 30, which will be described later. It has a second region B which is a region of the flow path 15 of the above. The bottom wall of the pumping section 30 and the bottom wall 13 of the crushing section 10 are substantially parallel to each other.

The pumping section 30 provided on the downstream side of the opening 14, specifically, the lower portion of the crushing section 20, has an impeller 31. The impeller 31 is connected to the drive means 50 via the drive shaft 51. The pressure feeding unit 30 is configured so that the impeller 31 is rotated by driving the driving means 50 and can be pressurized when sending the filth F and the washing water to the discharge port 60 by utilizing the centrifugal force. The bottom wall 13 of the crushing portion 20 corresponds to the upper wall of the pumping portion 30.

The prevention portion 40 is formed in a plate shape and in an arc shape along the peripheral wall 12, and is attached to the mounting portion 18 so as to cover the opening 14 on the downstream side of the crushing portion 20 and separated from the peripheral wall 12. It is fixed to the crushing section 20. The prevention portion 40 is provided so as to cover the opening 14 in a state of being separated from the peripheral wall 12, so that the filth F is allowed to flow out from the crushing portion 20 and the elongated foreign matter is prevented from flowing out from the crushing portion 10. ..

Next, the flow of the washing water and the filth F in the pumping toilet 1 will be described with reference to FIG.
The wash water and the filth F flow into the storage tank 10 via the connecting pipe 100 and are stored in the storage tank 10. After that, the drive means 50 is driven by the control unit 70 (see FIG. 1), and the rotating unit 21 and the impeller 31 of the crushing unit 20 connected to the drive shaft 51 rotate.

As the rotating portion 21 rotates, the washing water and the filth F stored in the storage tank 10 move outward from the rotation center of the rotating portion 21 due to centrifugal force, and the filth F collides with the outer wall 11 and this collision occurs. It is crushed by the energy when it is used. Thereby, the filth F can be reduced. The filth F larger than the size of the opening 14 collides with the outer wall 11 and then moves upward, and then moves toward the rotation center side of the rotating portion 21. The flow in which the filth F moves outward from the rotation center side of the rotating portion 21, then moves upward, and then returns to the center direction is repeated until the filth F becomes smaller than the opening 14.

Further, as the rotating portion 21 rotates, a flow in the direction along the peripheral wall 12 is also formed, and the filth F moves along the peripheral wall 12, and the peripheral wall 12 and the peripheral wall 12 when moving along the peripheral wall 12 The filth F can be crushed by utilizing the friction of.

The filth F that has been crushed by the crushing section 20 and has become smaller than the opening 14 is discharged from the opening 14 to the outside of the crushing section 20, that is, to the first region A of the flow path 15.

The filth F discharged from the opening 14 sequentially passes through the first region A and the second region B of the flow path 15 and flows into the pumping unit 30. Specifically, when the impeller 31 inside the pumping unit 30 is rotated by the driving means 50, the vicinity of the rotation center of the impeller 31 becomes a negative pressure, so that the washing water and the filth F existing in the flow path 15 are pumped. It is sucked into the portion 30. The suctioned washing water and filth F move outward from the rotation center of the impeller 31 by centrifugal force, so that the pressure increases, and the suction water and the filth F are pumped to the discharge port 60 and discharged to the outside of the pressure-feeding toilet 1.

By using such a crushing method using a water flow, it is not necessary to provide a crushing blade for crushing the filth F. The chance of foreign matter getting caught in the crushing blade can be reduced, and the risk of the drive means 50 being locked can be reduced.

Next, the control operation of the pumping toilet 1 will be described. FIG. 5 is a flowchart showing the control operation of the pumping toilet 1.

As shown in FIG. 5, the state in which the pumping toilet 1 is connected to the power source and is not used by the user is the standby state (step S100). When the control unit 70 detects the washing water by the water level detection unit 80, the water level detection unit 80 is turned on (step S101).

When the water level detection unit 80 is turned on in step S101, the control unit 70 drives the pumping unit 30 to perform the drainage operation as the first water level detection operation (step S102). When the control unit 70 drives the pumping unit 30 for Tsu 1 second for the first predetermined time in step S102, the washing water in the storage tank 10 is discharged to the outside of the pumping toilet 1, and the cleaning water in the storage tank 10 is discharged to the outside. The water level drops.

After that, the control unit 70 executes the first water level measurement in which the water level detection unit 80 measures the water level in the storage tank 10 (step S103). Although steps S100 to S103 described above are explanations of the control flowchart from the standby state, a signal about the cleaning operation is also input to the pumping toilet 1 from the outside. Specifically, when the operation unit 90 is operated by the user, a cleaning operation signal is transmitted to the control unit 70 (step S200).

When the control unit 70 receives the control operation signal, the notification unit 95 notifies the reception BEEP sound (step S201). After that, the control unit 70 performs the first water level detection operation (step S102). After that, the first water level measurement for measuring the water level inside the storage tank 10 after the first water level detection operation is executed (step S103).

When the control unit 70 determines in the first water level measurement in step S103 that the water level is lower than a predetermined water level, it determines whether the operation unit 90 has been operated (step S109). When the control unit 70 determines that the operation unit 90 has been operated in step S109, it receives a control operation signal from the operation unit 90 and supplies wash water to the toilet bowl TB (step S110). More specifically, in step S110, the control unit 70 opens and closes the on-off valve 3 to supply the wash water to the toilet bowl TB.
If it is determined in step S109 that the operation unit 90 is not operated, the process returns to the standby state (step S111).

The control flow of step S200, step S201, step S102, step S103, step S109, and step S110 described above is the first mode. By executing this first mode, when the control unit 70 receives the cleaning operation signal, the water level in the storage tank 10 can be grasped by executing the first water level measurement, so that the storage tank 10 can be grasped. It is possible to prevent the washing water from being supplied to the toilet bowl TB and prevent the water from overflowing from the pumping toilet bowl 1 even though the water level of the toilet bowl is equal to or higher than the predetermined water level.

Next, when the water level is measured in step S103, if the control unit 70 determines that the water level in the storage tank 10 is higher than the predetermined water level, the second is longer than the first water level detection operation (step S102). The water level detection operation is executed (step S104). More specifically, in the first water level detection operation, the pumping unit 30 is operated for Tsu 1 second, but in the second water level detection operation, the pumping unit 30 is operated for Tsu 2 seconds. By operating in this way, assuming that the washing water that cannot be discharged in the first water level detection operation is stored inside the storage tank 10, by operating the pumping unit 30 for a long time, the water inside the storage tank 10 is discharged. A large amount can be discharged to the outside of the pumping toilet 1, and the water level in the storage tank 10 can be lowered. The control flow of step S104 and step S105 becomes the second mode.

After performing the second water level detection operation in step S104, the control unit 70 again executes the second water level measurement in which the water level detection unit 80 measures the water level inside the storage tank 10 (step S105). After executing the second water level measurement, the control unit 70 determines that the water level inside the storage tank 10 is lower than the predetermined water level, and executes steps S109 to S111 described above.

When the control unit 70 determines that the water level inside the storage tank 10 is higher than the predetermined water level when the second water level measurement is executed, the control unit 70 operates the pumping unit 30 in order to lower the water level in the storage tank 10. The third water level detection operation is executed (step S106). After that, the control unit 70 executes a third water level measurement in which the water level detection unit 80 measures the water level inside the storage tank 10 (step S107).

If the control unit 70 determines that the water level inside the storage tank 10 is lower than the predetermined water level after executing the third water level measurement, the control unit 70 executes steps S109 to S111 described above. Further, when the control unit 70 determines that the water level inside the storage tank 10 is higher than the predetermined water level after executing the third water level measurement, the water level is continuously equal to or higher than the predetermined water level, that is, the water level inside the storage tank 10. Is not lowered, the continuous water level detection error is notified from the notification unit 95 (step S108). By notifying the notification unit 95, the user can know that maintenance is required and can quickly prepare for the maintenance work. Although the notification from the notification unit 95 has been described with reference to an example after the third water level measurement is executed, the notification may be performed after the second water level measurement is executed.

Next, the fluctuation of the water level inside the storage tank 10 will be described. FIG. 6 is a diagram showing a normal water level fluctuation of the storage tank 10.

As shown in FIG. 6, when the water level detecting unit 80 detects the washing water, the pumping unit 30 is driven. By driving the pumping unit 30, the water level inside the storage tank 10 will drop. If the operating unit 90 is operated during the driving of the pumping unit 30, the driving of the pumping unit 30 is stopped. After that, the water level detection unit 80 determines whether or not the water level inside the storage tank 10 has dropped. Here, it is determined based on a predetermined predetermined water level to determine whether or not the water level has dropped. In FIG. 6, when the pumping unit 30 is stopped, the water level in the storage tank 10 is lower than the predetermined water level. Therefore, in order to start the supply of washing water, the on-off valve 3 is opened and closed for washing. To start.

When the washing water is supplied, the pumping unit 30 which is a normal cleaning operation is driven to lower the water level of the storage tank 10, that is, the washing water is discharged to the outside of the pumping toilet 1.

Next, the water level fluctuation when the water level inside the storage tank 10 is high will be described. FIG. 7 is a diagram showing the water level fluctuation of the storage tank 10 when the second mode is executed.

As shown in FIG. 7, when the water level detecting unit 80 detects the washing water, the pumping unit 30 is driven. By driving the pumping unit 30, the water level inside the storage tank 10 will drop. If the operation unit 90 is operated while the pumping unit 30 is being driven, the driving of the pumping unit 30 is stopped. After that, the water level detection unit 80 determines whether or not the water level inside the storage tank 10 has dropped. In the case of FIG. 7, since the water level detection unit 80 detects the washing water, the control unit 70 does not open the on-off valve 3 and executes the second mode. By executing the second mode, the water level inside the storage tank 10 is lowered, and at the end of the execution of the second mode, the water level inside the storage tank 10 becomes lower than the predetermined water level. When it is detected that the water level inside the storage tank 10 is lower than the predetermined water level, the on-off valve 3 is opened to supply the wash water to the toilet bowl TB.

Next, a case where the water level inside the storage tank 10 does not drop will be described. FIG. 8 is a diagram showing a case where the water level of the storage tank 10 does not drop.

As shown in FIG. 8, when the water level detecting unit 80 detects the washing water, the pumping unit 30 is driven. If the operation unit 90 is operated while the pumping unit 30 is being driven, the driving of the pumping unit 30 is stopped. After that, the water level detection unit 80 determines whether or not the water level inside the storage tank 10 has dropped. In the case of FIG. 8, since the water level detection unit 80 detects the washing water, the control unit 70 does not open the on-off valve 3 and executes the second mode. However, since the water level in the storage tank 10 does not drop even if the second mode is executed, the third mode is executed. Since the water level in the storage tank 10 does not drop even when the third mode is executed, the operation of the pumping toilet 1 is locked on the assumption that the water level detecting unit 80 continuously detects the washing water. More specifically, the drive of the pumping unit 30 is locked as shown in FIG.

In FIG. 8, the drive of the pumping unit 30 is locked when the water level detecting unit 80 continuously detects the washing water, but the notification unit 95 lowers the water level in the storage tank 10. You may notify that you do not.

According to the above-described invention, the washing water from the pumping toilet 1 is determined by detecting the water level inside the storage tank 10 when the operation unit 90 is operated and determining whether or not to supply the washing water to the toilet TB. Can be prevented from overflowing.

In the above-described invention, the water level is measured by the water level detection unit 80 after the pumping unit 30 is driven after the operation unit 90 is operated, but the operation of the pumping unit 30 is performed at the same time as the operation unit 90 is operated. It is also preferable to stop the water level and measure the water level.

When the water level is measured by the water level detection unit 80 after the pumping unit 30 is driven after the operation unit 90 is operated, the cleaning water is supplied to the toilet bowl TB after the user operates the operation unit 90. Although it takes time, the operation unit 90 is operated and the pumping unit 30 is stopped at the same time to measure the water level, so that the user operates the operation unit 90 until the washing water is supplied to the toilet bowl TB. There is no need to wait for a long time, and usability can be improved.

Further effects and variations can be easily derived by those skilled in the art. For this reason, the broader aspects of the invention are not limited to the particular details and representative embodiments expressed and described as described above. Therefore, various modifications can be made without departing from the spirit or scope of the general concept of the invention as defined by the appended claims and their equivalents.
