Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pressure-feeding / draining device capable of cleaning the inside of a container, and a pressure-feeding / draining toilet using the same.
[0002]
[Prior art]
Japanese Patent Application Laid-Open No. 4-290559 discloses a cutter for preventing the urine fragments crushed by the cutter from adhering to the inside of the container or the water level sensor for the purpose of improving the reliability of the pressure drainage device and the maintenance workability. It is shown that the upper surface and the side surface of the screen disposed around the screen have a double structure.
[0003]
[Problems to be solved by the invention]
The pressure drainage device is equipped with a pressure pump, water level detection switch and crushing device in the water tank, collects wastewater such as manure, remaining hot water in the bath, washing and wash surface, etc. in the water storage tank, and the water level detection switch It is a device that detects the water level, activates a pressure pump, simultaneously crushes manure with a cutter, and pumps and discharges manure and waste water that have passed through a screen arranged around the cutter through a drain pipe. Such a pressure drainage device is required in places where water is forced to be drained, such as a basement installed at a lower position than a sewer pipe or a building where the drain pipe cannot be inclined. Furthermore, in the future, it is expected to be frequently used in a system in which the diameter of the drain pipe is reduced to reduce the piping space, and a system in which the drain pipe is made flexible to improve the workability.
On the other hand, it is particularly important in maintenance and hygiene management of the pressure drainage device, so that the urine and toilet paper finely crushed by the cutter do not remain in the storage tank, so that there is no odor and insects are not generated in the storage tank. One example is keeping it clean.
[0004]
However, the above-mentioned pressure drainage device is composed of a cutter which is a pulverizer and a screen on a cylinder with a small hole arranged around the cutter, and the urine crushed by the cutter is caused by the rotational force of the cutter. There was a problem in that it flew through the small holes to the four sides of the storage tank, and the crushed pieces adhered and remained in the storage tank, causing odor and causing insects in the summer. In addition, there is a problem that if this crushed piece adheres to the water detection switch to cause a malfunction of the water level detection switch or the tank is opened during maintenance, it is very unsanitary.
In Japanese Patent Laid-Open No. 4-290559, in order to keep the inside of the water storage tank clean, it is shown that a partition lid and a partition plate are provided so as to cover the upper surface and the side surface of the screen. The urine caught between the partition plates leads to a reduction in the grinding efficiency, and in turn a reduction in the capacity of the pressure drainage device. In addition, human urine floating in the storage tank and “red” from the human body contained in the miscellaneous wastewater may stick to the storage tank, and it cannot be said that the water storage tank is kept clean. Furthermore, since floating dirt adheres to the water level detection switch, there is a risk of causing a malfunction.
[0005]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to maintain a sanitary condition in the container and further reduce the malfunction of the pressure pump to increase the reliability, and the same. It is to provide a pressure-feeding drainage toilet.

[0023]
The operation of the pressure-feeding / draining device according to this embodiment will be described with reference to FIG.
Drainage from the bathtub or the washing place flows into the tank 50 from the first inflow part 51 or the second inflow part (not shown) through the bathtub drain pipe 25 or the washing place drain pipe (not shown).
Waste water from the toilet flows through the toilet pipe 41 and flows into the screen 81 in the tank 50 from the toilet inflow part 52. The filth larger than the hole diameter of the screen 81 remains in the screen 81, and the filth and drainage smaller than the hole diameter flow down to the tank 50.
The waste water that flows into these tanks 50 is stored in the tank 50, and when the water level in the tank 50 rises, the water level sensor 77 detects the water level, operates the pumping pump 70, and at the same time, a cutter attached to the upper part of the pumping pump 70. 82 rotates. When the cutter 82 rotates, the filth remaining on the screen 81 is crushed, and the crushed filth falls into the tank 50 from the hole of the screen 81. The waste water and the crushed filth are sucked from the suction port 73 by the pressure feed pump 70, are pumped from the discharge port 74 to the pressure feed pipe 72, and are fed to a sewage pipe (not shown).
However, some of the filth crushed by the rotation of the cutter 82 is scattered in the tank 50 by the rotational force and may adhere to the side wall of the tank 50, the screen 81, or the water level sensor 77.
[0024]
The valve control unit 63 counts the operation of the pressure pump 70, and counts from the previous cleaning as shown in FIG. 5, and transmits the open signal to the cleaning electromagnetic valve 62 at the same time that the pressure pump 70 operates for the fifth time. To do. The cleaning electromagnetic valve 62 is opened by this signal, and the cleaning water flows into the vertical water discharge unit 66 and the horizontal water discharge unit 67 from the external water supply source. Here, the external water supply source has pressurizing means to pressurize the cleaning water, and the cleaning electromagnetic valve 62 has a built-in constant flow valve, and the cleaning water having a constant flow rate is supplied to the vertical water discharge unit 66 and the horizontal water discharge. The part 67 can be supplied. The washing water whose flow rate has been adjusted in this manner is spouted from the hole formed in the side surface of the vertical water discharge section 66 in the tank wall direction so as to wash away dirt mixed in the tank 50 and dirt mixed with drainage. . Further, water is discharged from the hole in the front toward the water level sensor 77, and the filth adhering to the water level sensor 77 is surely washed away. The washing water discharged from the horizontal water discharge part 67 mainly washes the filth adhering to the screen 81 and prevents clogging of the holes of the screen 81. Moreover, water is discharged from the water outlet that opens to the side in a horizontal direction, and the tank wall surface is cleaned. The valve control unit 63 transmits a close signal to the cleaning electromagnetic valve 62 30 seconds after the cleaning electromagnetic valve 62 is in the open state, and the cleaning electromagnetic valve 62 is closed to supply each water discharge unit. Water supply stops and cleaning is completed. The washing water discharged during this time is sent to a sewer pipe (not shown) by the pressure feed pump 70 in the same manner as other drainage.
The cleaning solenoid valve 62 is set to be closed when the power is turned off. When a power failure occurs during cleaning, the pump 50 stops and the cleaning stops at the same time, so the cleaning water does not overflow into the tank 50. In addition, when the tank is opened for maintenance, it is performed after the power is turned off, and it is possible to prevent the washing water from being blown out due to a malfunction when the tank is opened.

Odors and insects can be prevented from entering from the ventilation portion 53.
[0038]
Moreover, in the said pressure-feed drainage toilet, the sequence of a control part can be variously changed. For example, the trigger switch 104 is for urine and urine. When the urine is used, as shown in FIG. 14, the trigger switch 104 for urine is turned ON and the bowl water supply solenoid valve 103 is immediately opened for a certain time. Wash bowl 101. {Circle around (2)} Although the motor unit 76 is driven after a certain time, the tank 50 is not cleaned because it does not contain dirt or paper. {Circle around (3)} When the tank water level is reduced and the motor stop water level sensor 107 is activated, the motor unit 76 is stopped and the pumping drain is also stopped. At the same time, the cleaning electromagnetic valve 62 is opened, and the water level in the tank 50 is restored with relatively clean water while cleaning the tank 50.
Thereby, the inside of the tank 50 can be cleaned only when necessary, and there is a water saving effect.
