As shown in FIGS. 8 and 9, a submersible pump 3 and a water level detection switch 4 are installed inside a storage tank 2 sealed with a lid 1. The above water level detection switch 4 is
When the increase / decrease in the water level in the storage tank 2 is detected and when the water level reaches a predetermined level, the submersible pump 3 is automatically operated to discharge human waste and gray water. The miscellaneous drainage inlets 5 are provided at the lower portions on both sides of the storage tank 2, and drainage from the rest of the bath, the washing and washing surface, etc. flows in. A cutter 8 is fixed coaxially with the submersible pump 3 to a rotary shaft of a vertical electric motor 6 fixed integrally with the submersible pump 3. A human waste inflow port 9 provided above the front of the storage tank 2 is connected to a drain port of a flush toilet (not shown) and communicates with a side surface of the screen 7. Further, the submersible pump 3 has a suction port in a recess 11 at the bottom of the storage tank 2 and is connected to the discharge port of the submersible pump 3 under pressure and drainage pipe 10.
Rises in the storage tank 2 and is guided to the outside from the upper portion of the side surface. Further, a partition cover 12a configured to be fitted is attached to the upper surface of the screen 7, and a partition plate 12b formed integrally with the partition cover 12a is provided so as to cover the periphery of the screen 7 with a gap. .

Next, the operation of the conventional human waste crushing and pressure-feeding device constructed as described above will be described. The excrement that flows from the flush toilet together with the transport water in the low tank (not shown) flows into the screen 7 through the excrement inlet 9, and the transport water passes through the eyes of the screen 7 and flows down into the storage tank 2 for storage. Raise the water level in tank 2. When the water level rises above the set water level of the water level detection switch 4, the submersible pump 3 is operated to start discharging carrier water. At the same time, the human waste and the toilet paper remaining in the screen 7 are crushed by the cutter 8, and when they are smaller than the mesh of the screen 7, they flow into the storage tank 2 together with the carrier water, and are pumped to the pumping drainage pipe 10 by the submersible pump 3. Further, when crushed by the cutter 8, it passes through the eyes of the screen 7 and scatters in all directions. At this time, the crushed pieces hit the partition wall 12a and the partition plate 12b, flow down along the wall of the partition plate 12b, collect in the recess 11 provided at the bottom of the storage tank 2, and are sucked by the submersible pump 3 and discharged to the outside of the tank.

Therefore, the air pressure sensor 108 is installed in the ventilation pipe 82.
Since it is located in the pipeline, not only is there no adhesion of sticky filth contained in wastewater mixed with filth, but also because it does not come into contact with water, no scale of water adheres and the reliability of the sensor section is high. Regarding the method of detecting the supply detection sensor 109, by rotating the cleaning operation lever 76 during the cleaning operation, the spindle 86, which is its rotation axis, also rotates. When the supply detection sensor 109 detects the rotation of the spindle 86, the start-up information is transmitted to the start-up unit 56, and the pressure-feeding device is started up. Therefore, since the supply detection sensor 109 can be detected in accordance with the cleaning operation mechanism, the supply detection sensor 109 has few malfunctions and is highly reliable. Further, the cleaning water can be supplied to the urinal body 68 depending on the rotation direction and the rotation amount of the cleaning operation lever 76 of the tank 77 when the stool is used and when the urine is used. Therefore, the supply detection sensor 109 can identify stool cleaning and urine cleaning by detecting the rotation direction and the rotation amount of the spindle 86.
Therefore, the pumping device is activated only during stool cleaning, the pumping device is not activated during urine cleaning, and the bypass pipe 63 communicating with the drain pipe 75 from the main body container 52 is used to drain water. It saves electricity without having to start up. In addition, supply sensor 109 is code B
81 is connected to the starting unit 56, and the pressure sensor 108 which is the second sensor is connected in parallel to the starting unit 56 by the code A80. In the starting unit 56, the code A80 and the code B81 are changed by the switching lever 79 which is a switching unit. By selecting and switching, even if one of them fails, the other can be used, and the reliability of the system becomes higher.
In the case of the direct pressure type toilet bowl as shown in FIG. 4, the same effect can be obtained by substituting the water pressure sensor 112 for the supply detection sensor 109 of this embodiment. Further, after the atmospheric pressure sensor 108 senses the start-up information, the tank outlet 92
It takes some time for the flush water to be discharged to the toilet body 68 and for the wastewater containing dirt to be discharged to the screen 51 from the toilet outlet (not shown). Therefore, by delay-controlling this time by a delay control unit (not shown) and starting the pressure-feeding device, it is possible to efficiently crush and pressure-feed, and it is possible to save electricity.

Next, FIG. 7 shows a schematic side view of a toilet bowl drainage system according to a fifth embodiment of the present invention. Hereinafter, constituent elements that are the same as or correspond to those in the above-described embodiment will be assigned the same reference numerals and detailed description thereof will be omitted. The toilet drainage system 67 shown in FIG. 7 has a structure in which a tank 77, a toilet bowl including a toilet body 68, and a main body container 52 of the pressure-feeding device are watertight via a connecting pipe 71 and are directly connected to each other. Further, the front panel 93 and the counter 94, which are concealing portions, conceal the rear portion of the toilet body 68, the tank 77, the main body container 52 of the pumping device, the activation unit 56, and other cords. Next, this embodiment will be described while showing the operating state of the pressure feeding device. At the time of urination, the user is detected by the human body detection sensor 103 provided in the lower front part of the toilet body 68,
When the urinal is separated from the toilet body 68 after the urination, it is determined whether it is stool or urine according to the detection time, and the information is transmitted to the automatic cleaning device 95 which is an electric drive unit by the code C96, and the automatic cleaning device 95 automatically The cleaning water is supplied from the tank discharge port (not shown) of the tank 77 to the ball surface (not shown) of the toilet body 68, and the waste water is discharged from the toilet discharge port (not shown). And is discharged to the screen 51 through an inflow port (not shown) of the main body container 52.
Here, the detection information transmitted to the automatic cleaning device 95 through the code C96 is further transmitted to the activation unit 56 as the activation start information by the code D97, so that the pressure feeding device is activated and the dirt in the screen 51 is not mixed. The waste water is crushed by the cutter 66, discharged from the small holes 64 of the screen 51, stored in the bottom of the main body container 52, passed through the pressure feed pipe 59 by the pump 55, and discharged into the drain pipe 75 from the outlet (not shown). Here, the automatic cleaning device 95 electrically operates an internal motor (not shown),
By rotating the spindle 86 shown in FIG. 6, the valve 88 is opened to supply the cleaning water, and the power is supplied by the power cord B101. On the other hand, the pressure-feeding device also has a mechanism for electrically actuating an internal motor to actuate the pump 55 and the cutter 66, and supplies the electricity by a power cord A100. Power cord A100 and power cord B101
Is taken from the power supply 102 which is a common power supply unit. Therefore, the power can be centralized and only one outlet in the toilet room is required. Further, the front panel 93 and the counter 94 allow the tank 77 and the main container 5 of the pumping device.
2. By hiding the activation unit 56 and other cords, not only does the appearance look good, but also mischief by which the cords are cut can be prevented.
