For this reason, a pumping part will be arrange | positioned so that it may communicate with a stored water surface. At this time, there is a problem that the filth attached to the pumping portion where the filth easily adheres due to the narrow flow path is peeled off from the pumping portion by buoyancy after the pumping is finished, and floats on the surface of the stored water. In particular, since the flush toilet apparatus is arranged in the user's living room, when the filth rises on the surface of the accumulated water and the odor of the filth is generated, the user is uncomfortable. In addition, when the filth is floating on the water storage surface at the next use, the user is uncomfortable.

  Therefore, the present invention has been made to solve the above-described problems, and filth floats on the water storage surface of the water storage section, generates odors, or is uncomfortable for the user who uses the toilet device next time. An object of the present invention is to provide a toilet device which can prevent giving a toilet.

  The upper portion of the rotary shaft 28 is attached to the electric motor 30, extends downward in the vertical direction, and the lower portion is attached to the center of the rotating body 26. The rotating shaft 28 extends through the water reservoir 14 to the rotating body 26, and directly transmits the driving force of the electric motor 30 to the rotating body 26. Instead of the rotary shaft 28, the rotary shaft is formed by a non-contact type rotation transmission mechanism using a magnet or the like so as not to penetrate the ceiling surface of the water reservoir 14, and accumulates the driving force of the electric motor 30. You may be comprised so that it may transmit indirectly to the rotary body 26 via the water part 14. FIG. The electric motor 30 is a DC brushless motor, and variable speed control is possible.

  The pumping device 20 forms a centrifugal pump capable of realizing a high head. The pressure feeding device 20 includes an impeller 34 that constitutes a rotating impeller, a pump chamber 32 that constitutes a casing that houses the impeller 34, a rotary shaft 36 that rotates the impeller 34, and an electric motor that drives the impeller 34 and the rotary shaft 36. And a motor 38.

  The impeller 34 is rotated about a rotation shaft 36. The impeller 34 includes a disk-shaped disk part 34a and a protruding part 34b provided so as to partially protrude from the disk part 34a. Due to the centrifugal force generated by the rotation of the impeller 34, the filth and washing water are pushed out from the pump chamber 32 toward the drain trap pipe 12 relatively strongly and pumped.

  The pump chamber 32 has an impeller 34 disposed therein. An inlet 32a of the pump chamber 32 is formed at the center of the pump chamber 32, and the lateral flow path 25 is connected to the inlet 32a. An outlet 32b of the pump chamber 32 is formed on the outer periphery of the upper portion of the pump chamber 32, and the inlet 12b of the drain trap pipe 12 is connected to the outlet 32b. The rising pipe 12 a of the drain trap pipe 12 extends in the tangential direction of the outer periphery of the pump chamber 32.

  The rotating shaft 36 is disposed sideways so as to extend in the front-rear direction of the toilet body 2. The rotating shaft 36 has a base attached to the electric motor 38 and a tip attached to the center of the disk portion 34a. The rotary shaft 36 extends through the pump chamber 32 to the impeller 34 and directly transmits the driving force of the electric motor 38 to the impeller 34. Instead of the rotation shaft 36, the rotation shaft is formed by a non-contact type rotation transmission mechanism using a magnet or the like so as not to penetrate the side wall of the pump chamber 32, and the driving force of the electric motor 38 is supplied to the pump chamber 32. It may be configured to indirectly transmit to the impeller 34 via the. The electric motor 38 is a DC brushless motor, and variable speed control is possible.

  The filter 22 is disposed on the bottom surface of the water reservoir 14 below the pulverizer 18. The filter 22 is disposed between the water reservoir 14 and the pressure feeding device 20, preferably between the water reservoir 14 and the lateral flow path 25. The filter 22 forms a large number of passage openings 22a having a predetermined size. Only the filth crushed to a predetermined size or less can pass through the passage opening 22 a, while the filth larger than the predetermined size is restricted from passing and remains on the filter 22 in the water reservoir 14.

  The control unit 24 controls the water supply unit 4, the crushing device 18, and the pressure feeding device 20 by the operation of the operation unit by the user or the setting by the user. The control unit 24 includes a CPU, a memory, and the like for performing these controls. The control unit 24 is electrically connected to the water supply unit 4, the crushing device 18, the pressure feeding device 20, and the like, and sends an operation signal to these devices and the like to operate each device and the like.

  The lateral flow path 25 extends laterally from the lower portion of the water reservoir 14 to the inlet 32 a of the pump chamber 32. The ceiling surface of the lateral flow path 25 also extends substantially horizontally from the inlet 32 a of the pump chamber 32.

Next, the restriction mechanism of the portable toilet device 1 will be described with reference to FIG.
In the present embodiment, the impeller 34 is arranged vertically in the pressure feeding device 20. The pump chamber 32 has a vertically installed impeller 34 disposed therein. In the pump chamber 32, a portion in the pump chamber 32 of the rotary shaft 36 extending from the impeller 34 is arranged. The drain trap pipe 12 is provided with an inlet 12 b on the downstream side of the pumping device 20 and on the upper side of the pump chamber 32. The lateral flow path 25 is connected to the inlet 32 a of the pump chamber 32. The filter 22 is provided between the water reservoir 14 and the lateral flow path 25. In addition, the outlet 32 b of the pump chamber 32 is disposed in a region near the vertically lower side of the water storage surface Wt inside the drain trap pipe 12. The inlet 32a of the pump chamber 32 is opened in the lateral direction, and the outlet 32b of the pump chamber 32 is arranged to be opened upward.

By including all or part of these configurations, when the dirt attached to the pump chamber 32, the impeller 34, and a part of the rotary shaft 36 of the pressure feeding device 20 is detached when the operation of the pressure feeding device 20 is stopped, Since the ascending pipe 12a rises from the outlet 32b at the upper part of the pump chamber 32 and rises from the inlet 12b of the drain trap pipe 12, the separated filth from the pump chamber 32 or the like of the pressure feeding device 20 Lifting to W0 is prevented. Therefore, all or a part of these configurations acts as a regulating mechanism that prevents the separated dirt from floating on the water storage surface W0 of the water storage unit 14.
Further, the separated filth is unlikely to flow out from the inlet 32 a at the center of the pump chamber 32 to the lateral flow path 25 extending in the lateral direction. Therefore, the separated dirt is prevented from floating from the pump chamber 32 or the like of the pressure feeding device 20 to the water storage surface W0 of the water storage unit 14. Such a configuration also acts as a regulating mechanism.

Further, the filth floating from the pump chamber 32 of the pressure feeding device 20 is lifted from the outlet 32 b at the top of the pump chamber 32, and is lifted from the inlet 12 b of the drain trap pipe 12 through the rise pipe 12 a. To the stored water surface Wt. Such a configuration also acts as a regulating mechanism.
In addition, even if the separated filth flows from the inlet 32a at the center of the pump chamber 32 to the lateral flow path 25 on the side of the water reservoir, the passage of the filth separated by the filter 22 can be suppressed. it can. In addition, even if the filth has once passed through the filter 22, the filth may become larger again due to entanglement between the filth in the pump chamber 32 (for example, entanglement of fibers such as paper contained in the filth). Such filth can also be restricted from passing by the filter 22. Such a configuration also acts as a regulating mechanism.

  In the regulating mechanism, the pump chamber 32 is arranged so that the vertically installed impeller 34 is arranged inside, and the drain trap pipe 12 is arranged above the pump chamber 32. The impeller 34 is an impeller arranged vertically with a rotating shaft 36 extending in the horizontal direction as a center. The axial width D1 of the impeller 34 is smaller than the radial width D2. The pump chamber 32 is formed in a vertical cylindrical shape so as to cover the vertical impeller 34. Therefore, the axial width D3 of the pump chamber 32 is smaller than the radial width D4. The width of the outlet 32b of the pump chamber 32 is formed to be the same width as the tube diameter width D5 of the drain trap pipe 12, and is slightly smaller than the axial width D3 of the pump chamber 32. Since the impeller 34 is disposed vertically in the pump chamber 32, the electric motor 38 is disposed in the lateral direction of the impeller 34. Therefore, the inlet 12b of the drain trap pipe 12 is provided above the horizontal impeller 34, and the electric motor 30 of the pressure feeding device 20 is placed vertically compared to the case where the electric motor 30 is arranged above or below the horizontal impeller 34. The height in the vertical direction of the pressure feeding device 20 when the impeller 34 is disposed can be suppressed, and the height of the toilet body 2 can be suppressed. Therefore, the height of the toilet seat of the toilet body 2 can be prevented from being increased by the pressure feeding device 20 provided between the water reservoir 14 and the drain trap pipe 12. Therefore, it is possible to guide the filth separated from the impeller 34 and the pump chamber 32 to the water storage surface of the drain trap pipe 12 while adopting a configuration that prevents the toilet seat height of the toilet body 2 from increasing. Such a configuration also acts as a regulating mechanism.

As a modification, the restriction mechanism may be configured to have a recess formed in the lateral flow path 25 or the ceiling surface of the rising pipe 12a extending obliquely upward. The filth that floats up by the recess recessed upward from the ceiling surface can be captured in the recess. Therefore, the restriction mechanism prevents the filth that floats from floating on the water surface W0 of the water reservoir 14. Such a configuration also acts as a regulating mechanism.
Furthermore, as a modification, the regulating mechanism may be configured to further include a connection flow path that extends obliquely upward from the outlet 32 b of the pump chamber 32 to the inlet 12 b of the drain trap pipe 12. Also in this case, since the inlet 12b of the drain trap pipe 12 is arranged above the outlet 32b of the pump chamber 32, the separated filth rises from the outlet 32b of the pump chamber 32 to the connection channel, and the pump chamber 32 is led from the inlet 12 b of the drain trap pipe 12 on the upper side of 32 to the stored water surface Wt inside the drain trap pipe 12. Such a configuration also acts as a regulating mechanism.

  Next, the operation (action) of the portable toilet apparatus according to the above-described embodiment of the present invention will be described with reference to FIGS. In FIG. 5 to FIG. 10, the hatched portion schematically shows a state where cleaning water is stored.

  As shown in FIG. 5, the user uses the toilet body 2 and the filth (stool, urine, toilet paper, etc.) A enters the bowl portion 10. In this state, the water supply unit 4 is in a stopped state, and the crushing device 18 and the pressure feeding device 20 are also stopped. The accumulated water surface W1 is slightly raised by the entry of the filth A from the accumulated water surface W0 in the standby state before cleaning.

  Next, as shown in FIG. 6, when the user operates an operation switch or the like of the operation unit, the cleaning operation is started. When an operation switch or the like of the operation unit is operated, the operation command is transmitted to the control unit 24, and the control unit 24 sends a water supply command to the water supply unit 4 based on the command, and the water supply unit 4 sends the water supply command to the bowl unit 10. Water is supplied for a predetermined time, and the bowl portion 10 is washed with the washing water B. The filth A is moved into the reservoir 14 by the cleaning water B. The stored water surface W2 is at a position that is further elevated than the stored water surface W1 by supplying the cleaning water B. The crushing device 18 and the pressure feeding device 20 are still stopped.

  Next, as shown in FIG. 7, the control unit 24 drives the pressure feeding device 20 to drain the cleaning water C by a predetermined flow rate that lowers the water level of the water storage surface W2 to the position of the water storage surface W3. The amount of cleaning water present in the water storage section 14 is reduced, and the water storage surface of the water storage section 14 becomes the position of the water storage surface W3. During the driving of the pressure feeding device 20, the water supply unit 4 remains stopped, and the crushing device 18 also remains stopped. Of the filth A, the filth of a predetermined size or larger does not pass through the filter 22 and remains in the water reservoir 14.

  Next, as shown in FIG. 8, the control unit 24 drives the electric motor 30 of the crushing device 18 to rotate the rotating body 26 to perform a crushing operation of filth. At this time, the pressure feeding device 20 remains stopped. The rotation of the rotating body 26 causes a rotational flow in the water reservoir 14, and the filth is stirred and pulverized in the water reservoir 14. The water supply unit 4 remains stopped. The filth A is crushed and becomes a filth a having a predetermined size or less.

  As shown in FIG. 9, when the crushing of the filth is completed, the control unit 24 stops the crushing device 18 and drives the pressure feeding device 20. The filth a can pass through the filter 22. The pressure feeding device 20 pumps (discharges) the washing water and the filth a to the drain pipe 16 via the drain trap pipe 12. Almost all of the cleaning water and filth a in the water reservoir 14 are discharged by the pumping device 20. In this way, the filth a is discharged from the water reservoir 14. Since the rotator 26 pulverizes filth on the upstream side of the pumping device 20 and the filth a is relatively small, the rotator 26 is not easily entangled with the impeller 34 and the pump chamber 32 of the pumping device 20, and the filth adheres to the pumping device 20. It is hard to do.

  As shown in FIG. 10, the control unit 24 operates the water supply unit 4 again to supply water to the bowl unit 10. Therefore, the wash water is stored in the water storage part 14, and the water storage of the water storage surface W0 is formed. At this time, the crushing device 18 and the pressure feeding device 20 are stopped. The control unit 24 stops the water supply unit 4 when a predetermined flow rate of cleaning water is supplied, and ends a series of cleaning operations.

  As shown in FIG. 10, when the control unit 24 stops the pumping device 20 and then stops the pumping device 20, the pump 24, the impeller 34, and a part of the rotating shaft 36 of the pumping device 20 are partly stopped. When the attached filth a peels off, the peeled filth a floats up because it is relatively small in diameter and light. The separated filth a rises from the outlet 32b at the top of the pump chamber 32 due to the configuration of the regulation mechanism, rises from the inlet 12b of the drain trap pipe 12, and is guided to the water surface Wt. The separated filth a is prevented from flowing out from the inlet 32a at the center of the pump chamber 32 to the lateral flow path 25 by the configuration of the regulating mechanism. Even if the separated filth a flows from the inlet 32a in the central portion of the pump chamber 32 to the lateral flow path 25 on the water storage section side, the passage of the filth a separated by the filter 22 of the regulating mechanism is suppressed. Is done. In this way, the regulating mechanism prevents the separated filth a from floating from the pump chamber 32 or the like of the pressure feeding device 20 to the water storage surface W0 of the water storage unit 14. When the peeled filth a is guided to the pooled water surface Wt of the drain trap pipe 12, it is possible to prevent the peeled filth a from generating an odor outside the portable toilet device 1.

Next, the effect by the portable toilet device 1 by this embodiment mentioned above is demonstrated.
According to the portable toilet device 1 according to the present embodiment, when the filth a adhering to the pressure feeding device 20 is peeled off when the pressure feeding device 20 is stopped, the regulation mechanism causes the peeled filth a to be collected from the pressure feeding device 20 in the reservoir 14. Prevents floating on the water surface W0. Therefore, when the pumping device 20 is stopped, it is possible to prevent the filth a from floating on the water storage surface W0 of the water storage unit 14 and generating odors or causing discomfort to the user who uses the portable toilet device 1 next time. it can.

  The structure which forms a recessed part in the middle of a flow path is also considered so that the filth a which the regulation mechanism peeled may float on the stored water surface W0. According to the portable toilet device 1 according to the present embodiment, filth does not stay in the recess or cause a flow pressure loss compared to the structure in which the recess is formed. Therefore, in the structure in which the regulation mechanism guides the filth a floating from the impeller 34 of the pressure feeding device 20 to the water storage surface Wt inside the drain trap pipe 12 downstream of the pressure feeding device 20, the filth discharge performance can be further improved. Furthermore, since the regulating mechanism guides the separated filth a to the pooled water surface Wt of the drain trap pipe 12, it is possible to prevent the filth from rising to the pooled water surface W0 of the pooled water portion 14.

  Furthermore, according to the portable toilet device 1 according to the present embodiment, the regulating mechanism has the drain trap pipe 12 provided with the inlet 12b above the impeller 34 of the pressure feeding device 20. Therefore, the restriction mechanism guides the separated filth a to the water storage surface Wt of the drain trap pipe 12 with a relatively simple configuration without complicating the structure of the toilet device, and the separated filth a is pumped. Can be prevented from floating to the water storage surface W0 of the water storage unit 14.

  Furthermore, according to the portable toilet device 1 according to the present embodiment, when the filth a adhering to the pressure feeding device 20 is peeled off when the pressure feeding device 20 is stopped, the peeled filth a is temporarily transferred from the pressure feeding device 20 to the reservoir portion 14 side.
