JP 2005-105581 A. JP 2007-23492 A. JP 2007-93434 A.

  In an apparatus equipped with a closed storage tank for pumping drainage, the pump operating part (such as the impeller part) must be submerged at the start of operation in order to perform an appropriate discharge operation every time the toilet is used. Since the internal storage tank needs a certain volume, it becomes an obstacle to making the whole apparatus compact.

  In addition, when a drainage pump operating part is incorporated in the discharge channel as described in Patent Document 3 without a storage tank, the apparatus can be made compact. However, the pump operating part and the bowl part serving as a waste receiver are Since it is continuous, it is necessary that the bottom of the bowl part and the pump operating part are always submerged. Then, even if the sewage in the bowl portion is discharged by a pump, complete discharge (a state where the bowl portion is empty) is not performed. For this reason, in order to retain clean water in the bowl part after using the toilet, the water amount necessary for discharging the filth is discharged, and then continuously until the inside of the bowl part and the discharge path are filled with clean water. It is necessary to discharge the water and the amount of water used becomes large.

  Therefore, the present invention incorporates a pump operating part in the discharge path, and the pump operating part is always submerged so that wastewater can be discharged efficiently, so that the pumping discharge toilet apparatus can be made compact and the amount of water used can be reduced. A new toilet device with a suction pumping and drainage mechanism is proposed.

  A toilet apparatus with a suction pressure feeding / draining mechanism according to claim 1 of the present invention is a reverse provided so as to be continuous with a bowl part, a water discharge mechanism part that discharges a predetermined amount of clean water to the bowl part, and a bottom part of the bowl part.

A drainage pipe section having a rising volume and connected to an external discharge pipe. Immediately after supplying the cleaning water from the water discharge mechanism section to the bowl section, the pump operation section starts operating, and at least in the trap pipe section. The drainage sewage is activated and stopped until it reaches an empty state, and the rising volume of the drainage pipe section is set so that the pulverized sewage fills the pump operation section after the pump operation section is stopped. It is what.

  Thus, the waste water to be discharged from the bowl portion of the toilet device once flows upward from the bottom of the bowl portion at the trap conduit portion, overflows the top of the trap conduit portion, and flows into the lower pressure feed conduit portion. Then, it flows upward again from the pumping pipe section at the rising portion of the drain pipe section, and is discharged outside the apparatus through the external discharge pipe.

During operation of the pump, the sewage is crushed and solids are crushed into sewage and pumped from the pumping line to the drainage line. Drains out of the device through an external discharge pipe. Accordingly, the waste can be sufficiently discharged by using the minimum amount of cleaning water required for the discharge of the waste.

  In addition, the sewage to be discharged in the bowl part is entirely sent to the pressure feeding pipe part by the suction action by the pump through the trap pipe part, but the discharge amount by the operation of the pump operating part is set in advance (setting of the operation time). In addition, pumping drainage (pump operation) is continued until the trap pipe section is empty (the pump operating section is submerged) or the pumping pipe section is empty (the pumping fluid is lost and the engine is idle or immediately before idling). And stop in this state. When the operation of the pump operating unit stops, the pressure feeding pressure is released, the flow of fluid in the entire drainage pipe is stopped, and the water level is adjusted naturally.

  The water level adjustment is performed by causing the crushed sewage remaining at the rising portion of the drain pipe part to flow backward until it reaches the same water level as the downstream side of the trap pipe part. In this reverse flow, the rising volume is set in advance so that the pulverized sewage does not overflow to the upstream side of the trap pipe section. Therefore, the pump operating part is always in a submerged state at the start of operation, and the drainage function is efficiently exhibited without causing idling (rotation in a non-submerged state) at the start of operation.

  Next, an embodiment of the present invention will be described. The toilet apparatus of the first embodiment shown in FIGS. 1 to 6 includes a bowl part 1, a water discharge mechanism part 2, a trap pipe part 3, a pressure feed pipe part 4, and a drain pipe part 5, and is provided outside the toilet device. An external discharge pipe 6 serving as a drainage channel and a control unit 7 for controlling the operation of each unit are attached. In the illustrated example, the diameter of the pipe is greatly expressed. However, in the actual apparatus, the discharge pipe (trap pipe section 3, pressure feed pipe section 4, drain pipe section 5 and external discharge pipe 6) has a diameter of 20 to 50 mm. The pipe diameter is adopted.

  The bowl portion 1 has an appropriate container shape with the bottom side as a discharge port 11 in the same manner as a normal toilet apparatus. The water discharge mechanism unit 2 includes a water storage tank unit 21, a water discharge pump 22, and a water discharge port 23. The water storage tank unit 21 is provided with a float valve 24 therein, and a water pipe is provided at a predetermined time (when a water level drop is detected). The water discharge pump 22 is connected to the water storage tank 21 and the water discharge port 23 and discharges a predetermined amount of water from the water discharge port 23 at a predetermined time. The operation is based on a control signal from the control unit 8. To do.

  The trap pipe section 3 is composed of an upstream pipe 31 and a downstream pipe 32 and is an inverted U-shaped pipe. The upstream pipe 31 is connected to the discharge section 11 at the bottom of the discharge bowl section 1 and exhausts to the top of the pipe. A pipe 33 is connected, and an exhaust valve 34 is provided on the exhaust pipe 33. The exhaust valve 34 is an automatic exhaust valve that is provided at a position higher than the water level of cleaning water B in the bowl portion 1 to be described later, and performs a passing operation only in one direction by a pressure difference. In particular, although the exhaust pipe line is not shown, the air discharged from the exhaust valve 34 is discharged to the atmosphere at a position apart from the vicinity of the apparatus.

  The pumping pipe line part 4 is connected to the downstream pipe 32 and the drain pipe line part 5 of the trap pipe part 3, and is positioned below the both pipe lines, and is a pump operating part ( Impeller etc.) 42 is interposed.

  The drainage pipe part 5 includes a riser pipe 51 having a predetermined volume from the connection part with the pressure feed pipe part 4, and an end portion of the riser pipe 51 is connected to the external discharge pipe 6 to form an inverted U-shaped pipeline. In addition, an intake pipe 52 is connected to the top of the pipe, and an automatic intake valve 53 that operates according to a pressure difference is attached to the intake pipe 52. Further, a flow rate adjusting valve 54 is provided at a connection point between the drain pipe section 5 and the external discharge pipe 6.

  The external discharge pipe 6 is a conduit for discharging sewage from the toilet device to a predetermined disposal place (such as a sewer pipe).

  The control unit 7 includes a switch unit 71 and a predetermined control circuit (program). When the switch is turned on after using the toilet, the water discharge pump 22 and the drive motor 41 (= pump operating unit 42) are set at a predetermined timing and at a predetermined level. It controls so that it may operate | move by operation time.

  Thus, the toilet device is in the state shown in FIG. That is, in the state where the bowl reservoir water (clean water) C is accumulated in the bottom of the bowl portion 1 and in the upstream pipe 31 of the trap conduit portion 3, the pulverized sewage E at the previous use is contained in the pressure feed conduit portion 4. Remains.

  Next, when the switch portion 71 is operated using the toilet, the water discharge pump 22 is activated and the tank water A is discharged as cleaning water B into the bowl portion 1. When the cleaning water B is discharged into the bowl portion 1, the water level in the bowl portion 1 increases, and the waste water to be drained D (cleaning water B, bowl stored water C, and excrement) flows into the trap pipe portion 3 (FIG. 3). ). In particular, air that is present in the trap pipe 3 when the sewage D to be discharged flows into the trap pipe 3 is discharged from the exhaust valve 34 due to the high water level in the bowl 1 (exhaust a). Is done.

  Immediately after the washing water B is discharged, the operation of the pump operating unit 42 starts. Since the pump operating unit 42 is submerged in the pulverized sewage E when the pump operating unit 42 starts to operate, an idling state (rotation in a state where no pumping fluid is present) does not occur, so that the pump function can be efficiently performed. Is done.

  By the operation of the pump operating part 42, the discharge target sewage D in the bowl part 1 is sucked in the direction of the pressure feed line part 4, and the excrement contained in the discharge target sewage D is pulverized by the pump operation part 42 and pulverized. The sewage E is pumped from the pressure feed line 4 to the drain line 5 and discharged outside the apparatus through the external discharge pipe 6 (FIG. 4).

  Since the discharge amount by the pump operation unit 42 is determined by the operation time, an operation time corresponding to the required discharge amount (the amount of water stored in the bowl + the amount of water for washing) is set in advance, and all of the waste water D to be discharged is pump operation unit. When passing through 42, the operation of the pump operating unit 42 is stopped. At the time of the stop, the crushed sewage E remains in the riser pipe 51 of the drain pipe section 5 as shown in FIG.

  Since the pumping pressure of the pulverized sewage E disappears due to the pump operation unit 42 being stopped, the pulverized sewage E remaining in the rising pipe 51 portion is backflowed and stabilized until it reaches the same water level as the downstream pipe 32 of the trap pipe part 3. (FIG. 6). When the external discharge pipe 6 has a small diameter and continues to be sealed in the reverse flow, the resistance to the reverse flow is obtained, but external air introduction (intake b) from the automatic intake valve 53 due to a pressure drop due to a drop in the water level of the riser pipe 51. As a result, the backflow is made smooth.

  Of course, in this reverse flow, the volume of the riser pipe 51 is set in advance so that the crushed sewage E does not overflow to the upstream pipe 31 side of the trap pipe section 3. Further, tap water or the like is supplied to the water storage tank unit 21 by the operation of the float valve 24 until a predetermined amount is reached.

  When the pump operation unit 42 is stopped, the water level is adjusted, the water discharge pump 22 is operated again, a predetermined amount of clean water is supplied from the water discharge port 23 to obtain the bowl stored water C, and the use shown in FIG. 2 is started. Return to the state.

  In this way, by operating the pump operating part 42 disposed in the middle of the discharge path after using the toilet, the waste target waste water D in the bowl part 1 is sucked and pulverized and pumped out to be discharged out of the apparatus. After the operation is stopped, a predetermined amount of pulverized sewage E is caused to flow backward so that the pump operating unit 42 is always submerged.

  The toilet apparatus according to the second embodiment shown in FIG. 7 includes a bowl portion 1, a water discharge mechanism portion 2, a trap conduit portion 3, a pressure feed conduit portion 4, and a drain conduit portion 5 as a first configuration. Although it is the same as that of a form, especially the temporary storage tank part 8 is provided. The configuration with the same number is the same as the configuration of the first embodiment, and the description of the configuration and operation is omitted.

  The temporary storage tank section 8 is a flat tank, the lower end port 35 of the downstream pipe 32 of the trap pipe section 3 is opened near the bottom surface of the temporary storage tank section 8, and the inlet of the pump operating section 42 of the discharge pipe section 4 is also the same. Are opened near the bottom of the temporary storage tank 8. Further, the temporary storage tank 8 is provided with an exhaust passage 81 and an exhaust valve 82 similar to the exhaust passage 33 and the exhaust valve 34 of the trap pipe 3.

  Similarly to the first embodiment, in the second embodiment, the drive motor 41 is operated for a predetermined time when the cleaning water B is used after the toilet is used, and the discharge target wastewater D discharged to the temporary storage tank 8 is started up. It discharges to the external discharge pipe 6 through the pipe 51.

  By stopping the pump operation part 42, the pulverized sewage E remaining in the rising pipe 51 part flows backward, and at least the lower end port 35 of the trap pipe part 3 is blocked. The air remaining in the upper space of the temporary storage tank 8 during the backflow of the pulverized sewage E is released to the atmosphere at a position away from the apparatus by the exhaust valve 81.

  In the second embodiment, in particular, by providing the temporary storage tank 8, a plurality of toilet parts constituted by the bowl part 1 and the trap pipe part 3 provided with a plurality of sets of water discharge mechanisms 2 are provided as the pressure feed pipe part 4. And the toilet apparatus provided with the some toilet part can be easily constructed | assembled by connecting to the temporary storage tank 8 provided with the single drainage part comprised by the drain pipe part 5. FIG.

  The adoption of the temporary storage tank 8 is not limited to the integrated type as in the first embodiment, and the wastewater D to be discharged from the plurality of toilet units 01 is also temporarily stored in the third embodiment described below. It may be stored and connected to the suction hose 9 of the single discharge mechanism unit 02. Also in the fourth embodiment, the discharge target sewage D from the plurality of toilet units 03 is temporarily stored, and the discharge mechanism unit You may make it connect the front-end | tip of the trap pipe line part 3 used as the front-end | tip of 04. FIG.

  Next, the toilet apparatus according to the third embodiment shown in FIGS. 8 to 12 will be described. This embodiment is formed by a toilet part 01 and a discharge mechanism part 02. The toilet part 01 includes a bowl part 1, a water discharge mechanism part 2a, and a trap pipe part 3. The discharge mechanism part 02 is a pressure feed pipe part 4. And a drain pipe 5a and a suction hose 9 having a desired length.

  The suction hose 9 is connected to the pressure-feeding pipe line part 4 and is provided with a connection part 91 with the trap pipe line part 3 at the tip. Of course, a downstream connection portion (socket) 36 connected to the connection portion 91 is provided on the outlet side of the trap pipe portion 3. The suction hose 9 may be previously attached to the discharge mechanism part (entrance of the pressure feed pipe part 4) 02, or may be connected by a socket structure.

  The bowl part 1 and the trap pipe part 3 of the toilet part 01 are the same as those in the basic first embodiment, and the water discharge mechanism part 2a is not particularly equipped with a water storage tank part in order to achieve compactness. A tap pipe is connected to directly discharge tap water as cleaning water B.

  The discharge mechanism unit 02 is provided with the suction hose 9 described above, and the pumping circuit unit 4 is basically the same as that of the first embodiment, and the control unit 7 that controls the operation of each unit also has predetermined control (water discharge). The valve opening time of the mechanism portion 2a, the operation time of the drive motor 41, etc.) are set.

  In particular, the discharge pipe section 5a employs a rising tank 51a having an appropriate volume in which the drive motor 41 of the pumping circuit section 4 can be placed in place of the rising pipe 51.

  The rising tank 51a is provided with a partition 57 in which a discharge part 56 connected to the external discharge pipe 6 is formed at an upper part of an outlet of the pump operating part 42 (an inlet 55 serving as a bottom surface of the rising tank 51a). The other is formed in the air storage space 58. The partition 57 is provided at a height that satisfies the sewage operation described later, and an intake pipe 52 having an automatic intake valve 53 interposed is connected to the upper part of the air storage space 58.

  The rising tank 51 a has a sealed structure except for a portion connected to the external discharge pipe 6 at the discharge portion 56. Further, instead of the partition 57, the discharge portion 56 may be formed by forming the discharge hose 56a shown in the fourth embodiment with a tubular body, and the pipe end (inlet side) may be suspended to an appropriate height in the rising tank 51a.

  Thus, in the toilet device, the suction hose 9 is connected to the trap pipe section 3, and the detour height of the suction hose 9 can be set arbitrarily, but at least the pump operating section 42 of the pressure feed pipe section 4 has its height. The position is set at a position lower than the height of the boundary portion between the upstream pipe 31 and the downstream pipe 32 of the trap pipe section 3.

  The use start state of the toilet device is the state shown in FIG. In a state where the bowl reservoir water (clean water) C is accumulated in the bottom of the bowl portion 1 and in the upstream pipe 31 of the trap pipe section 3, the pressure feed pipe section 4, the downstream pipe 32 of the trap pipe section 3, and In the suction hose 9, pulverized sewage E from the previous use remains.

  Next, cleaning water B is discharged from the water discharge mechanism 2a into the bowl 1 by operating a switch (not shown) of the controller using the toilet (FIG. 10). When the cleaning water B is discharged, the water level in the bowl portion 1 is increased, and the sewage D (cleaning water B, bowl stored water C, and excrement) flows into the trap pipe section 3 and exists in the trap pipe section 3. The discharged air is discharged from the exhaust valve 34 (exhaust a).

  Immediately after the discharge of the cleaning water B, the operation of the pump operation unit 42 is started, and the discharge target sewage D in the bowl unit 1 is sucked in the direction of the pressure feed line unit 4 and is discharged by the pump operation unit 42. Excrement contained in the sewage D is crushed to become crushed sewage E, and the crushed sewage E is sent from the inlet 55 into the rising tank 51a.

  When the pulverized sewage E reaches the lower end of the partition 57 in the rising tank 51 a, the air storage space 58 is in a sealed state, and the pulverized sewage E is pumped from the pressure feed line 4 to the discharge unit 56 and through the external discharge pipe 6. It will be discharged out of the device. When the pump operates for a predetermined time and stops, a part of the pulverized sewage E remains in the rising tank 51a (FIG. 11).

  Since the pumping pressure due to the stop of the pump operating unit 42 is lost, the crushed sewage E remaining in the rising tank 51a flows back and stabilizes until it reaches the same water level as the downstream pipe 32 of the trap pipe unit 3. In particular, in the above-described reverse flow, when the pressure in the air storage space 58 is reduced due to a drop in the water level of the rising tank 51a, outside air is introduced from the automatic intake valve 53 (intake b), and the reverse flow is smoothly performed.

  Simultaneously with the stop of the pump operating section 42, a predetermined amount of clean water is supplied into the bowl section 1 by the operation of the water discharge mechanism section 2 to become the bowl stored water C, and the use start state shown in FIG.

  In this way, by operating the pump operating part 42 disposed in the middle of the discharge path after using the toilet, the waste target waste water D in the bowl part 1 is sucked and pulverized and pumped out to be discharged out of the apparatus. After the operation is stopped, a predetermined amount of pulverized sewage E is caused to flow backward, and the pump operating unit 42 is always submerged, thereby preventing a reduction in drainage efficiency of the pump operating unit.

  In the third embodiment, the trap line 3 and the pressure line 4 are connected by the suction hose 9, and the toilet part 01 and the discharge mechanism 02 can be arranged at positions separated from each other. It is also possible to install the compact toilet unit 01 in a desired place, such as a nursing bed.

  Next, the toilet apparatus according to the fourth embodiment shown in FIG. 13 will be described. This embodiment includes a toilet unit 03 and a discharge mechanism unit 04 as in the third embodiment. The toilet part 03 includes a bowl part 1 and a water discharge mechanism part 2a, and is provided at the upstream end of the trap pipe part 3a described later, particularly at the end of the discharge path of the discharge port 11 provided at the bottom of the bowl part 1. An upstream connection portion (socket structure) 37 and a discharge connection portion 12 that is detachable are provided.

  The discharge mechanism section 04 is configured by a trap pipe section 3a, a suction hose 9, a pressure feed pipe section 4 and a drain pipe section 5a, and particularly at the upstream end of the trap pipe section 3a. An upstream connection portion 37 is provided which is detachably connected to 12. The length of the suction hose 9 is arbitrarily determined depending on the location of the toilet device, but is limited to a length that can achieve the object of the present invention (always submerging the pump drive unit). Alternatively, the discharge mechanism unit 04 may be incorporated so as to be integrated, or may be structured so as to be detachable from the inlet of the pressure feed conduit unit 4.

  The fourth embodiment employs the configuration of the third embodiment as it is except for the configuration described above.

  Thus, the toilet device arranges the toilet part 03 at a desired location, and also arranges the parts of the pressure feed conduit 4 and the drain conduit 5a in the discharge mechanism 04 at the desired location, and the trap conduit It is used by being connected to the upstream connection portion 37 of 3a and the discharge connection portion 2 of the toilet cloth 3, and its operation is the same as in the third embodiment.
