The present invention provides a suction-type flush toilet system including a butt washing hot water nozzle and a hot air drying nozzle, wherein a suction means rotated by an electric motor, a waste crusher, a gas / liquid A sewage treatment device with a separation mechanism is connected, assists with defecation including suction stimulation, suction drying that cleans the local area with pulsed water flow and dries in a short time, and a urinal with standing urine using suction power The present invention relates to a defecation assist suction type flush toilet system having a function of preventing peripheral contamination.

It is known that high concentrations of pathogenic bacteria can be found in the stool of patients suffering from infectious harmful bacteria (norovirus, rotavirus, Salmonella, O-157, Escherichia coli, etc.). If a person suffering from infectious harmful bacteria uses a conventional flush toilet and a toilet inside or outside the handwashing facility, hands and fingers contaminated with pathogenic bacteria after stool is wiped with toilet paper, various switches with flush fingers, flush knobs, Many cases have been reported from the Ministry of Health, Labor and Welfare, the National Institute of Infectious Diseases, etc., which caused secondary contamination by touching the toilet lid, hand wash faucet, common towel, door knob, door lock, patient's clothes, etc., and spread to food poisoning. . It has also been reported that elderly people die of heart disease, cerebral hemorrhage or vascular insufficiency such as cerebral infarction when breathing in the toilet. Defecation and wiping the buttocks after defecation are very difficult for the elderly and those with disabilities such as hemiplegia due to brain disorders.Severely ill persons must have their caregivers wipe the local area after defecation. There is also the problem of an aging society. Another problem is that the urinal in the standing position becomes unsanitary around the toilet. In view of this fact, there is a long-awaited need for a toilet that has a mechanism for assisting smooth defecation when a flush toilet is used and that does not require the operation of wiping the buttocks with toilet paper.

This application is a patent application in which the same inventor as in Patent Document 14 is improved with different solutions to the same object of the invention.

The conventional flush toilet device provided with the ass washing hot water nozzle and the hot air drying nozzle has the following problems.
That is, the first problem is that when the anus is wiped off with toilet paper after washing the local part with the conventional hot water shower cleaning, the hot water shower cleaning is often incomplete so that the residue of dirt comes to the toilet paper. .
The second problem is that in the method of drying by blowing dry hot air to a local area after washing with a hot water shower, it is necessary to take a long time to dry the hot water with a hot air drying part to feel “completely dried”. There was a problem in that it required disposal and the toilet user could not wait and was inconvenient to use.
As a result, the toilet user may not have a complete local cleanliness and the anus and the pubic area may be wet or moistened to remove the discomfort of getting wet after the shower shower. It is customary to wipe off the toilet with toilet paper, and hot air drying is not widely used in the world at present.
Therefore, the third problem is that the work of "wiping the buttocks with toilet paper", which is the cause of the outbreak of food poisoning even now when the toilet system has been developed due to the contamination and spread of the infectious pathogens, is not eliminated. It is.
The fourth problem is that it is difficult for a disabled person who has sequelae due to cerebral disorder to have a sequelae of hemiplegia or an elderly person who has weak abdominal muscles. Also, it is not easy to wipe the hips after defecation.
A fifth problem is that a conventional vacuum flush toilet is used for an aircraft or a Shinkansen train toilet, but the system cannot be used for home use as it is. Further, the patent document discloses an application example mainly for nursing care using a large-sized vacuum pump. However, there is a problem that a caregiver is troubled and a complicated system becomes large and expensive. As a sixth problem, it has been a long-standing problem to make the area around the toilet bowl unsanitary by splashing urine water in the standing urination process.

The solution of the present application is to devise the shape and structure of the toilet seat and the toilet so that the toilet bowl becomes a substantially airtight space when the toilet user sits on the toilet seat. The purpose of the present invention is to develop a process sequence for managing and controlling a device and a toilet device system having a waste disposal device having a gas-liquid separating means using a microcomputer, and solving the problems.

The present application has solved the above-mentioned six problems of the flush toilet having the conventional hot water washing and hot air drying device, and realized a toilet system that does not use toilet paper. By fundamentally resolving and eliminating urine in the vicinity of the toilet by urinating in the suction air flow, furthermore, assisting defecation so that disabled people with weak abdominal muscles and elderly people can defecate smoothly. After the defecation, it is possible to clean the buttocks sufficiently and completely dry it in a short time.Drainage is discharged to the sewer pipe by the flow of the washing water and exhaust air, and the toilet is made without toilet paper. The effect of greatly reducing the load can be expected.

In order to achieve the object of the present application, a method for solving the problem includes a pulse generator that sufficiently performs cleaning after defecation, and a filth having an electric motor that drives a suction unit that suctions and discharges air in a filth pool at a discharge port of a toilet. Connect a processing device and combine the functions of the in-line hot water creation device and hot air creation device to create a mechanism for defecation assist, pulsed water washing, and rapid drying, and mix the waste and toilet water excreted in the toilet bowl. The grinding rotary blade for fine grinding, the suction means, and the auxiliary rotating blades of the gas / liquid separation means are installed by penetrating the rotating shaft of one electric motor, and the electric motor is powerfully cooled by the separated clean air. The purpose of the present invention is to develop a waste disposal apparatus that discharges waste water to a sewer pipe and discharges waste liquid to a sewer pipe, and develops a toilet system that controls a toilet process sequence by a microcomputer.

FIG. 1 shows the overall configuration of the toilet-assisted suction-type flush toilet of the present application, FIG. 14 shows a control system diagram of the system, and FIG. 15 shows an overall flowchart of the toilet process.
The toilet process sequence includes a preparation process and a main process sequence.

As shown in FIGS. 5 and 6, the structure of the toilet 48 and the toilet seat 3 of the present application is provided with water-repellent resin layers 5 and 6 on at least one or both of the upper peripheral edge 7 of the toilet 48 and the opposing surface of the toilet seat 3. When the toilet user sits on the toilet seat 3, the gap is filled with the water-repellent resin layers 5 and 6.
Moreover, as shown in FIGS. 6, 6-a, 6-b, and 6-c, the shape of the toilet seat is raised in an inverted V-shape at the center line of the front portion of the toilet seat. The shape fills the space of the triangle to be created.

1 and 2 show a waste disposal apparatus 49.
A silent sirocco fan 12 for creating a suction airflow and a rotating body 13 of a waste crushing blade 14 are installed on a rotating shaft 20 of one electric motor 11, and the waste discharged from the waste storage 8 of the toilet 48 and the washing water are removed. When the electric motor 11 rotates at high speed and the sirocco fan 12 rotates, it falls into the crushing groove 16 of the waste crushing device 49 together with the suction airflow. The dirt is crushed by the rotation of the crushing blade 14 in the crushing groove 16, and the suction airflow and the filth water flow into the cyclone 18 over the outer wall 68 of the crushing groove 16 by centrifugal force. The wire does not flow into the cyclone 18 due to the wire mesh 90 provided on the outer wall 68 of the groove. When the wastewater containing the waste that has been pulverized into fine particles enters the suction airflow and the cyclone 18, the wastewater is separated into gas and liquid by centrifugal force.
At the center of the cyclone 18 is provided an air take-out pipe 22 for taking out a clean gas to the outside, and the rotation shaft 20 of the electric motor 11 passes through the center. Auxiliary wings 21 are installed on the rotating shaft 20 and rotate at the same rotation speed as the electric motor 11, so that the clean gas at the center of the cyclone device 18 is strongly sucked and air is pushed out. The clean air is guided to a hood 29 surrounding the electric motor 11 and used for cooling the electric motor 11.
The sirocco fan 12, the crushing blade 14, and the auxiliary wing 21 installed on the rotating shaft 20 of the electric motor 11 are simultaneously rotating, so that the above-described processing is performed simultaneously.

The electric motor 11 is a household power supply, an electric motor of 50 to 500 Watt is used, and has an output variable control circuit using a PWM control circuit. It is possible to adjust to the suction power desired by the user.
The microcomputer is programmed standard rotation of the electric motor 11 in accordance with the progress of the process, the suction amount speed of the electric motor 11 is "2-stage dry" process (M ³ / min) is the discharge amount of the drying hot air A low-speed rotation that does not exceed the speed is commanded by the microcomputer. However, at the "end" of the process, it is reset to normal rotation.

As shown in FIGS. 1 and 4, hot water used for local cleaning is produced by in-line hot water producing devices 39 and 32, and a heater 32 for heating supply water sent by a gear pump 30 in-line, and an in-line temperature sensor 34. And the heating control unit 39, and the temperature control was set to an appropriate temperature of 38 ° C and an appropriate temperature range ± 2 ° C.
The discharge power of the discharge hot water can be adjusted by controlling the rotation speed of the gear pump 30 from the remote 107 at hand.

The hot air used for drying is produced by an in-line hot air generating device 59, and includes a blower fan 50 for blowing in-line, an in-line hot air temperature sensor 54, a heater 53, and a heating controller 59. The temperature was controlled at an appropriate temperature of 38 ° C. and an appropriate temperature range ± 2 ° C. as in the case of the hot water. Alternatively, for hot air drying, it is also effective to design the temperature to be higher than the hot water temperature to speed up the drying. However, you must take into account dangers such as burns.

The hot water washing cylinder nozzles are provided with bidet washing 42 and 43 and buttocks washing 40 and 41, and a pulsed water flow generator 38 is provided immediately before the buttocks washing cylinder 40.
The pulse cleaning is prepared for the ass cleaning and defecation assist under the standard conditions shown in FIG.

The bidet cleaning cylinder nozzles 42 and 43 discharge a straight stream of water and are also used for bidet cleaning applications and "warm water stimulation" for defecation assist.

A method for creating a pulsed water flow with the pulse water flow generator 38 shown in FIGS. 8 to 10 is to stop the water flow flowing through the pipe by completely closing the on-off valve or to fully open the water flow by maximizing the water flow. Thus, a pulsed water flow is obtained.
FIGS. 8A and 8B show a type in which the valve plate 91 is moved up and down by an electromagnetic coil 93 with respect to a water flow to open and close.
9A and 9B are cylindrical rotating bodies in which the on-off valve 95 has a cylindrical shape and intersects the buttocks washing hot water pipe 45 at right angles. The rotating body has a cylindrical hole having the same diameter as the conduit 45, and the direction of the cylindrical hole is the conduit If it is the same as 45, it is fully open, and if the cylindrical hole is perpendicular to the conduit, it is fully closed.
When a single ON pulse is input, the cylindrical rotary valve 95 is a rotary stepping solenoid that rotates 90 degrees in one direction. When the fully open state of the water flow is electrically turned off for 2 seconds, the fully open state of the water flow for 2 seconds is turned on. Then, when the cylindrical rotary valve 95 rotates 90 degrees by the next ON pulse of the electric signal, the water flow is fully closed, and when the signal is OFF for 2 seconds, the water flow becomes a fully closed pulsed water flow for 2 seconds. By repeating this, the pulsed water flow shown in FIG. 7 can be obtained. In other forms, a similar pulsed water flow can be created using a ball valve.
In addition to the two types of pulsed water flow generators shown in FIGS. 8 and 9, a pulse waveform can be formed by the ordinary ON / OFF valve shown in FIG. 10, but the O-ring 97 on the contact surface of the valve can withstand many uses. There are no drawbacks.

The purpose of the defecation assist is to stimulate the anus by a straight water flow or a pulsed water flow to stimulate the anus and promote self-defecation, as described later. The straight water flow 123 or the pulsed water flow 124 can be remotely selected by the toilet user. Do.

In addition, pulsed water flow is a standard condition for flushing the buttocks after defecation, and a thick pulsed water flow is intermittently discharged to the wrinkles of the anus, and the anus is closed and opened to perform cleaning. Then, effective cleaning can be performed.
However, a narrow pulsed water flow may damage the anal mucosa and cause bleeding, so a thick pulsed water flow is preferable. It should be noted that the buttock is moved slightly back and forth and back and forth during cleaning, and that pulse cleaning is not continued at the same location for a long time.
A thick stream of about 10 mm diameter is used for the cleaning application of the present application.

When the consumption of hot water increases, cold water is discharged from the storage-type hot water creation device, which is uncomfortable. In order to avoid such a phenomenon, it is preferable to use an in-line type hot water producing apparatus.

The rapid drying process is performed in two stages. Most of the moisture in the wet area when the local area is washed is attached to the pubic hair and the skin in the form of water droplets. Therefore, when the “first-stage drying” is started by the “drying” command 119, the waste disposal apparatus The rotation of the electric motor 11 causes the sirocco fan 12 to rotate, thereby sucking the air in the waste pool 8 of the toilet at a high speed.
At this time, in the present application, as described above, the gap between the toilet seat 3 and the toilet bowl 48 is closed, and the suction airflow passes between the thighs of the toilet user and flows into the pubic region and the buttock in a concentrated manner. As a result, the pubic hair and skin vibrate violently, and the attached water drops are mechanically shaken off in a short time.

The second stage of “drying” is a process of drying a site wet with a large amount of warm air, and a small amount of moisture remaining on the skin surface is removed through the “first stage suction drying” process. Dry in a short time with hot air discharge. At this time, the sirocco fan 12 of the waste disposal device 49 rotates at a low speed, sucks the waste air from the waste outlet 9 of the toilet 48 with a suction airflow slightly smaller than the discharge amount of the hot air nozzle, and the warm air dries the local surface. The electric motor 11 and the sirocco fan 12 are programmed so as to rotate by suction to such an extent that does not decrease.

As a variable output control device of an electric motor, for example,
https://www.amazon.co.jp/PWM-400W-%E3%83%A2%E3%83%BC%E3%82%BF%E3%83%BC-%E3%82%B3%E3% 83% B3% E3% 83% 88% E3% 83% AD% E3% 83% BC% E3% 83% A9% E3% 83% BC-% E3% 83% A2% E3% 82% B8% E3% 83 % A5% E3% 83% BC% E3% 83% AB / dp / B00IK6P8KI
There is "PWM 10A 400W DC motor speed controller module".
As described above, a rapid drying process after cleaning was realized.

The suction force is used to stimulate the anus and rectum of the buttocks of the person sitting on the toilet seat 3, to enhance the defecation and assist the defecation, and the pulsed water flow generator 38 sufficiently cleans the anus after defecation. As a result, the process for drying the drying portion in a short time was completed.
As a result, the operation of wiping the buttocks with toilet paper is unnecessary, and a toilet flush suction type flush toilet system that solves the problems of the conventional flush toilet has been completed.

As described above, since the electric motor 11 rotates in each process, the sirocco fan 12, the crushing rotary blade 14, and the cyclone auxiliary wing 21 rotate each time, and even when dirt remains in the crushing groove 16, all the toilet processes are performed. There is a chance that the waste treatment process will be performed many times before the operation is completed, and all the waste can be discharged to the sewer 26.

Unlike the conventional flush toilet, the toilet bowl 48 according to the present application does not have a flush knob for discharging waste after the toilet, does not require a flush water tank, and does not require a siphon structure. It is a simple and compact toilet as a high-performance toilet system.

The toilet process sequence of the embodiment is shown below.
FIG. 15 shows the entire sequence of the toilet process sequence.
The first of the preparation sequences is a "hot water discharge standby" sequence shown in FIG. 16, in which the heater 32 is arranged in-line in the middle of the pipe 33 through which the supply water flows, as shown in FIGS. The PID control is independently performed by the signal of the temperature sensor 34 and the heating temperature control device 39, and the ON / OFF of the device is a system controlled by a microcomputer, which is shown in a "hot water discharge standby" sequence in FIG. In this way, the hot water that does not enter the appropriate temperature range is switched to the direction in which the second electromagnetic three-way valve 36 is released into the waste pool 8 so that only the hot water that enters the appropriate temperature range is discharged to the washing unit, and is then discharged. If a command to start the process of using hot water is not issued even if the temperature enters the appropriate temperature range, the hot water is discharged to the waste pool 8, T Low is set to 36 ° C., T High is set to 40 ° C., and the temperature is set. Is suitable around 38 ° C Only the warm water of the width so as to discharge towards the human body. However, the discharge hot water flow rate during the standby period is about 1/2 of the prescribed discharge hot water flow rate, and when there is a discharge command, the supply water of 100% of the design flow rate increases the rotation of the gear pump 30 to in-line hot water heating. The water is sent to the heater 32, and hot water is discharged to the cleaning part at a design rate.
Therefore, it is possible to discharge hot water at an appropriate temperature range and at a specified rate from the beginning of the discharge toward the cleaning site. For example, as an in-line hot water generator 39
There is http://www.nippon-heater.co.jp/products/liquid/sgl/.

The second of the preparation sequence is a "warm air discharge standby" sequence, in which an in-line warm air generator 51 having its own blower fan 50 as shown in FIG. 1 and FIG. An independent temperature control circuit 59 is provided to generate hot air having a set temperature range by the heating heater device 53, and ON / OFF of the device is controlled by a microcomputer. The appropriate temperature range of the hot air is also set to the same temperature as the hot water, and the hot air that is not within the set temperature range and the hot air during the period in which the dry hot air command is not received are passed through the sewage pipe 58 by the third three-way solenoid valve 55 through the sewage pipe 26. Has been released. However, it is on standby with the discharge hot air flow rate being about 1/2 of the design flow rate, and is switched to 100% of the design flow rate after receiving the dry hot air command to reduce the wasteful energy. I have less.
Therefore, it is possible to discharge at a design rate at an appropriate temperature width from the beginning of the hot air discharge.
For example, as in-line warm air generators 51, 53, 59
There is http://www.nippon-heater.co.jp/products/gas/hotwind/.

The first, second, and third electromagnetic three-way valves 35, 36, and 55 used in the apparatus structural diagram of the present invention shown in FIG. product / general-ball / T3.html T3 type AE1-120 and the like.
The solenoid valve 63 is a two-way solenoid valve for general use.

In the toilet process of the present invention, the standard conditions are programmed in the microcomputer, and the process conditions can be changed remotely. When the sequence end is instructed by the process “end” command, the sequence is reset to the standard conditions again. I have.

The first of the main process sequence of the present application is a “standing urination process” shown in FIG. Otherwise, the microcomputer determines that it is a “standing urinal process”.
Then, during execution of the “standing urination process”, even if a sequence start command of another process is erroneously pressed, the sequence is locked without being “started”. The sequence to be locked is “butt cleaning”, “bidet cleaning”, “defecation assist”, and “drying sequence”.
However, when the “standing urination process” is “finished”, the sequence lock is released.

It goes without saying that the "standing urination process" sequence is not initiated when the seating sensor senses.
When the “piss in the standing position” action is performed and the “piss discharge” command switch 113 is pressed, the electric motor 11 is driven and the sirocco fan 12 is rotated. The electromagnetic valve 63 opens along the wall of the waste pool 8 for about 10 seconds, flushing water flows from the upper edge 7 of the toilet bowl, and the waste water falls to the crushing groove 16 of the waste disposal apparatus 49.
Due to the strong suction airflow and the rotational centrifugal force of the crushing blade 14, the liquid level of the waste liquid becomes higher than the outer wall 68 of the crushing groove 16 and flows into the cyclone introduction passage 17 over the outer wall 68. The waste liquid flows from the tangential direction of the cyclone 18, the air and the liquid component are separated by the centrifugal force of the high-speed vortex of the cyclone 18, the liquid component is pushed to the wall of the cyclone 18, and the waste water discharge pipe below the cyclone 18. It flows down to 23 and is discharged to a sewer pipe 26 through a sewer pipe 25. The air component is taken out from an air take-out pipe 22 provided at the center of the cyclone. A waste prevention cover 19 is attached to the upper part of the air extraction pipe 22 so that waste water does not enter.
The rotation shaft 20 of the electric motor 11 penetrates through the center of the air extraction pipe 22, and the auxiliary wing 21 is installed on the rotation shaft 20. The auxiliary wings 21 installed on the rotating shaft 20 of the electric motor 11 are rotating in the same manner as the electric motor 11, and strongly suck / push out the clean air in the center of the cyclone which is not mixed with the liquid component. The electric motor 11 is conveyed to the hood 29 of the motor 11, cools the electric motor 11, and is then discharged to the drain 26 through the air discharge pipe 27.

The "piss discharge" command switch 113 is automatically turned off after 10 seconds, the sequence lock is released at the same time, and the "piss discharge" sequence is automatically "terminated".
When the toilet user exits, the human sensor detects the exit and the “post-washing” sequence shown in FIG. 24 is automatically performed, and the fourth solenoid valve 63 is turned on from above the waste pool 8 of the toilet 48. When opened, about 3 L of washing water flows to wash the waste residue on the toilet surface and the waste pool 8 surface, and also serves to stop the odor from the waste disposal device 49 by storing the wash water in the toilet odor stopper 69. I do. The fourth solenoid valve 63 is automatically turned off after 5 seconds.
This completes the “standing urination process”.

The second of the main process is the process sequence of “bide cleaning” shown in FIG. 19, and the preparation process of “hot water discharge standby” shown in FIG. 16 is performed as shown in FIG. If the "discharge standby" sequence is activated and a "hot water discharge" command is issued, the appropriate temperature of hot water can be discharged from the nozzle at any time.
When there is a command 114 to start “bidet cleaning”, the second three-way valve 36 is switched to a bidet nozzle pipe, and hot water of an appropriate temperature width is supplied to the bidet cylinder nozzles 42 and 43, and a straight water flow is discharged from the bidet nozzle 43. You.
The bidet washing can change the water force of the standard condition with the remote 117, 118 with the hot water flow of the straight water flow, and it is memorized when the water pressure condition is changed. When the "bidet cleaning" command is pressed again, the microcomputer determines that "the bidet cleaning is to be re-cleaned" by the same toilet occupant, calls the memory condition, and performs the cleaning under the same conditions as the previous cleaning conditions. The system is easy to use for the user. When the bidet cleaning process is completed, the process proceeds to a “first-stage suction drying” and a “second-stage hot-air drying” processes described later.

When the bidet cleaning and drying are completed, and the toilet user leaves the toilet seat, the seating sensor "detects leaving", the memory of the cleaning condition disappears, and the standard condition is reset.

The third sequence is “defecation assist” shown in FIG. 20, in which an elderly person with weak abdominal muscles or a disabled person gives warm water stimulation and suction stimulation to the buttocks to elevate defecation and perform self-defecation. It is a sequence that helps.
“Straight hot water flow stimulation” 123 and “pulse hot water flow stimulation” 124 are selected from the “defecation assist” command board 115, and the command switches of “stop hot water discharge” 125 and “suction stimulation” 126 are remote. It is prepared in. If the “defecation assist” command board 115 shown in FIG. 13 is installed independently of other command boards, it is easy for a toilet user to understand.

That is, in the case of defecation while sitting on the toilet seat 3 and the toilet bowl 48 having the structure proposed in the present application, first, a person who can defecate by himself performs defecation by himself, but a person with low constipation “straight warm water flow stimulation” 123 toward the anus. Is issued, the hot water of the straight water flow is discharged from the bidet hot water discharge nozzle 43 toward the anus under the standard condition. The toilet servant adjusts the position of the buttocks so that hot water is applied.

If the user desires to stimulate the anus with pulsed hot water stimulation and enhance the defecation of the bowel, selecting the "pulse hot water flow stimulation" command 124 switches the three-way solenoid valve 35 to supply hot water to the ass washing pipe. Then, the pulse water flow generator 38 is operated, and the same “pulse hot water flow stimulation” mode as the post-defecation pulse hot water flow shown in FIG. 7 composed of the straight water flow and the pulse water flow under the standard conditions is discharged from the nozzle.
In the case where defecation can be performed on its own due to the excitement raised by the warm water stimulation, the discharge of hot water is stopped by the “stop discharge of hot water” command 125 to “defecate”.

In addition, when the defecation convenience is low, when the "suction stimulation" command switch 126 is pressed, the electric motor 11 is driven, and the sirocco fan 12 rotates for about 10 seconds to discharge the air from the waste pool 8 of the toilet 48.
As shown in FIGS. 6 and 6-a to 6-c, the shape of the toilet seat of the present application has a structure 67 that rises on the center line of the front part of the toilet seat,
When sitting on the toilet seat, placing the thighs in the shallow U-shaped groove 66, and contacting both kneecaps with each other and closing the knee, a substantially triangular space on the center line formed by the thighs and the toilet seat The toilet seat 3 and the water-repellent resin layers 5 and 6 at the upper part of the toilet contact with each other as shown in FIGS. 1 and 5, and FIGS. Since the gap is closed, the waste pool 8 of the toilet 48 is substantially airtight.

When the "suction stimulation" switch 126 is turned on while sitting on the toilet 48 and the toilet seat 3 of the present application, the sirocco fan 12 of the waste disposal device 49 rotates at a high speed, and when the air in the waste pool 8 is sucked, the toilet user I feel the stimulation that my buttocks are strongly sucked. A similar "suction stimulus" is felt in the anus and rectum when the suction tube of a home vacuum cleaner is closed by hand. When the suction force is too large, the output of the electric motor 11 can be remotely adjusted by the suction force adjustment dial 127.
The electric motor 11 automatically turns off in about 10 seconds.

When stool or gas coming down near the anus of the rectum tries to come out of the anus, the feeling becomes exhilarating and “defecation” is performed.
Unless the suction stimulus is given by the defecation assist, it goes without saying that the posture of sitting on the toilet seat is as usual, with both kneecaps widened to shoulder width and relaxed.

However, even for those who are still unsatisfactory, the sequence is such that they can repeatedly stimulate the rectum and anus by repeating "warm water stimulation" and "suction stimulation". It is effective for those who have difficulty in defecation because they can defecate smoothly.

However, instead of the defecation assist that sucks the stool out of the rectum with a negative pressure, the “defecation assist” of the present application is to perform the defecation by itself and to enhance the defecation to encourage defecation.

When the defecation is completed, the process proceeds to the “butt washing” process shown in FIG.
The fourth sequence is a process of “tail washing” shown in FIG. 21. When a command 116 of “tail washing” is issued, the first electromagnetic three-way valve 35 is cut in a direction in which water flows through the tail washing cylinder 40. Instead, the hot water generated by the in-line hot water generators 32 and 39 forms the pulse water flow shown in FIG. 7 by the pulse water flow generator 38 shown in FIGS. 8A to 10B, and the nozzle 40 under the standard pulse water flow conditions. , 41, a thick warm water stream having a diameter of about 10 mm is discharged toward the anus. The thickness of the hot water flow is determined by the design of the nozzle port 41.
The flow pattern of the standard pulsed water flow shown in FIG. 7 is a pattern 100 in which a pulsed hot water flow in which a straight water flow 99 flows for about 5 seconds, then pauses for 2 seconds, and flows for 2 seconds is repeated 5 times, It is possible to wash off the dirt that has arrived at the details of the anal wrinkle with a shock wave that turns it on and off, and to change the water condition from the standard condition to “strong” or “weak”. The re-cleaning is a sequence in which the memory is called up and the cleaning is performed under the previous condition.
The ON / OFF condition for determining the pulse width of the pulsed water flow generator 38 is operated by inputting a pattern in advance to the microcomputer.
Since the in-line hot water generators 32 and 39 are used, it is possible to repeatedly discharge and clean the hot water for as long as necessary, and to sufficiently clean the tail.

FIGS. 8A to 10B show the fully opened and completely closed water states of the three types of pulsed water flow generators 38, respectively. In the embodiment, FIGS. 8A and 8B show the state. A pulsed water flow generator was used. Although the pulsed water flow shown in FIG. 7 can be generated by three types of pulse generators 38, the pulse generators 38 of FIGS. 8 and 9 have a structure that is resistant to wear and can withstand long use.

The fifth sequence is a "first stage suction drying" process sequence shown in FIG.
When the sirocco fan 12 rotates by the rotation of the electric motor 11 and sucks the air in the filth pool 8, the suction airflow passes between the thighs of the person sitting on the toilet seat 3 and concentrates violently on the pubic region and the buttocks. Passing while shaking pubic hair and skin. At that time, water drops adhering to the pubic hair and skin are mechanically shaken off. Most of the moisture that is wet due to the washing process and the butt warm water stimulation is present in the buttocks and the pubic area in the form of water droplets, so that most of the moisture has been removed by the suction airflow.

The “first-stage suction drying process” in FIG. 22 is “started” when the “dry” command 119 is pressed, and the “hot-air discharge” in FIG. 17 is prepared in preparation for “second-stage hot-air drying” in FIG. A "standby" process is started.
Then, the waste discharged into the waste pool 8 of the toilet 48 is sucked into the waste disposal device 49 together with the washing water.
When the sirocco fan 12 rotates, the filth, sewage and washing water are sucked by the suction airflow and fall into the crushing groove 16, and the crushing rotating body 13 having the plurality of crushing blades 14 installed on the rotating shaft 20 of the electric motor 11 operates at high speed. Because it is rotating, the filth is finely crushed and becomes as fine as crushed by a mixer.
The crushing groove 16 has a depth, and feces are crushed in the crushing groove 16 for a while. When the liquid level of the wastewater rises above the height of the outer wall 68 of the crushing groove 16, the wastewater enters the cyclone device 18 through the cyclone introduction path 17 together with the suction airflow.
Since the crushing groove 16 and the cyclone introduction path 17 are attached so that the suction airflow enters from the tangential direction of the cylindrical cyclone 18, the fine dirt and the suction airflow vortex at high speed in the cyclone 18.
In the cyclone 18, the fine dirt and the liquid component are pushed by the wall of the cyclone 18 by the swirling airflow, gather downward along the wall of the cyclone 18, flow into the waste water discharge pipe 23 provided at the lower part of the cyclone, The water is discharged to the sewer pipe 26 through the sewer pipe 25.

On the other hand, the clean air component from which the fine contaminants have been removed is taken out of the cyclone 18 from the center of the cyclone 18 by the air take-out pipe 22. The rotation shaft 20 of the electric motor 11 attached to the upper part of the waste disposal device 49 penetrates through the center of the air extraction pipe 22, and the auxiliary wing 21 attached to the rotation shaft 20 rotates at high speed to provide powerful air. The clean air cools the electric motor 11 because the clean air pipe 24 is connected to the electric motor hood 29 surrounding the electric motor 11 by generating a suction force and an air pushing force. Thereafter, the air is discharged to the sewer pipe 26 through the air discharge pipe 27.

The sixth sequence is the “second-stage hot air drying” shown in FIG. 23, and the electric motor 11 is automatically turned off after 10 seconds in the first-stage suction drying process, and then automatically again. The rotation is started.
In the “second-stage hot air drying”, the output of the electric motor 11 is reduced, and the sirocco fan 12 sucks a small amount of suction speed from the waste pool 8 at a low rotation speed.
This is a measure to prevent the drying effect of the hot air drying from being lost and to prevent the bad smell from reaching the toilet user's face.
This is because if the output of the electric motor 11 is large and the suction force of the sirocco fan 12 is large, the effect of hot air drying is reduced. This is because the stench of the filth pool comes up.
The microcomputer is programmed so that the output of the electric motor 11 is suppressed to a low output and the sirocco fan 12 rotates at a low speed.
The hot air discharge amount speed and the suction amount speed are determined at the design stage.

This delicate balance is set up by installing a pressure sensor that detects the differential pressure between the waste pool side and the atmosphere side, and using the hot air discharge rate from the nozzle so that the waste pool is slightly positive with respect to the atmospheric pressure. A method of controlling the rotation with a microcomputer so as to slightly reduce the speed of suction by the sirocco fan is also conceivable.

In the first-stage and second-stage drying sequences shown in FIG. 22 and FIG. 23, the hot-air discharge standby is started when the in-line hot air generators 51, 53, and 59 instruct “dry” 119. Therefore, it is in a state where the warm air can be discharged immediately for the second stage drying.
When the electric motor 11 starts rotating at a low speed designed by the microcomputer, a large amount of hot air is discharged from the hot air nozzle 57 at the same time.
The rotation of the electric motor 11 is programmed in the microcomputer so as to suck the air flow rate slightly lower than the discharge rate of the hot air from the waste disposal apparatus 49. The moisture remaining in the water is rapidly dried.
The user can continue until the toilet user feels “dry” in the second drying, and presses “END” 120 to end the “second drying” process.
The power of the electric motor and the power of the in-line warm air device are turned off.

The toilet user prepares himself, leaves the toilet room, and starts the “post-washing” sequence shown in FIG. 24 when the motion sensor or the toilet seat sitting sensor detects the absence.

As described above, the “post-washing” is to turn on the fourth solenoid valve 63 to serve to wash the dirt and the like adhering to the surface of the dirt pool 8 of the toilet 48, and After installation, about 3 L of washing water flows from the washing outlet 62 and flows along the inner surface of the waste pool 8 to wash the inside of the toilet, and the washing water collects in the odor stopper 69 and the crush groove 16 of the toilet, It plays a role of stopping the odor from the waste disposal device 49.
As described above, the entire sequence of the toilet process is completed.

As shown in FIG. 14, the toilet system of the present invention is process-managed intensively in a microcomputer control circuit, and a sequence is programmed.
Process start and end commands from the hot water and hot air temperature sensor signals, motion sensor and seat sensor signal, remote switches 113, 114, 116, 119, 120 and hot water flow stimulation modes 123, 124, 125, A command signal for changing 117 and 118 of the cleaning water force is input to the microcomputer in the middle of the sequence, and a change of the high / low speed rotation control 126 and 127 of the sirocco fan 12 is programmed. Further, when the "end" command is pressed, the process in which the condition is changed is reset to the standard condition. The standard condition is also programmed in the microcomputer.
The power supply of the electric motor 11 of the waste disposal apparatus 49, the electromagnetic valve 63 including the electromagnetic three-way valves 35, 36, and 5, the power supply of the piping system, the hot water and hot air in-line heating system power supplies 39 and 59, and the apparatus power supply of the pulse water flow generator 38 Are ON / OFF controlled from the microcomputer control circuit to the power supply of all devices via the relay block according to the process sequence.
Although the temperature control of the in-line hot water device 39 and the in-line hot air device 59 has a local independent control circuit, it operates according to a sequence controlled by the microcomputer control circuit.

If the temperature of hot water and hot air exceeds 45 ° C., it is determined that an abnormality has occurred, and in an emergency state in the event of an abnormality, an emergency stop for stopping power supply from the microcomputer control circuit is given priority. Have.

The technical contents using the improved waste disposal apparatus as a second embodiment of the present invention will be described below.
Note that paragraphs (0011) to (0057) are descriptions of the specification of the earlier application (Japanese Patent Application No. 2018-127425), and the other paragraphs describe the technical contents of the second embodiment according to the present application. Things.

In the prior application, the water system used in the buttocks cleaning process is shown in FIGS. 1 and 4, a water system diagram, and FIG.
In a second embodiment of the later application, FIGS. 25 and 39 clearly show the water system using the pressure reducing valve 215 and the accumulator 214 in the water system diagram of the toilet system.
Further, FIG. 44 shows details of the pulsed water flow discharge water pressure waveform of FIG.
In the prior application, although not described, a pressure reducing valve is used for the main line of the washing water system, the water pressure of the entire nozzle water system is adjusted to a low water pressure, and the accumulator 214 is provided with a bidet pipe and a bottom cleaning pipe. It is installed at a close position upstream of the open / close solenoid valve.

In the earlier application, since the accumulator was not considered to directly affect the toilet function in FIG. 1 and FIG. 4, the accumulator for water hammer countermeasures uses a pulsed water flow generator 38 for rapidly closing and opening the waterway in the water system. Is considered to be understood to be used without being described, and the pressure reducing valve and the accumulator are omitted, and the simplified substantially rectangular wave is shown in FIG. 7 without any explanation. Is discharged to the anus, and the pressure reducing valve 215 and the accumulator 214 are actually used.
In the earlier application and the second embodiment of the present application, a shock wave having a suppressed impact force and a high cleaning ability remaining generated by interference between the pulsed water flow generator 38 and the accumulator 214 for countermeasures against water hammer. Pulsed hot water containing is used for ass washing.

In paragraph 0040 of the previous application, even in the defecation assist process, when a command of “pulse hot water flow stimulation” is issued once remotely, the same hot water flow as in the ass washing shown in FIG. 7 is discharged. It is described.
Also, in paragraph 0046, “The water flow pattern of the standard pulse water flow shown in FIG. It is a pattern 100 that is repeated and is washed with a shock wave that turns on and off dirt that has reached the details of the anal wrinkle.
FIG. 44, which is described in detail below, represents that a pulse flow including a shock wave with a reduced impact force included in a rising period of the pulse water flow at the time of ON is washed under standard conditions.

Again, in the second embodiment of the earlier application and the later application of the present application, the defecation assist and the pulse water flow generator 38 used for the buttocks cleaning process and the water hammer phenomenon occurring at the time of ON / OFF are prevented The function of the accumulator 214 and the discharge water of the present application having a substantially rectangular wave discharge force discharged toward the buttocks cleaning section will be described below for better understanding.

In general, sudden opening and closing operations of water flow pipes for flowing city water with high water pressure, such as household baths, washing machines, water heaters, toilet facilities, industrial air conditioners, and plant facilities In applications where a valve body that performs water hammering is installed, if water hammer countermeasures are not taken, a water hammer phenomenon occurs, and in the worst case, a shock wave enough to destroy water-based equipment shown in FIG. 40 is generally generated. Is known.

Regarding the function of the accumulator 214, for example, a structure in which nitrogen gas from NOK is sealed in a bladder made of thick rubber is widely used. http://www.nok.co.jp/product/fluid.html

Please refer to.
In the piping flow path that constitutes the solenoid valve that opens and closes rapidly in the water system, close to the solenoid valve device that turns the water channel ON / OFF in order to prevent the water system device from being destroyed by the water hammer phenomenon Therefore, it is common sense to install a water hammer prevention device such as an accumulator on the upstream side.

The effect of the accumulator 214 and the shock wave generated by ON / OFF of the pulse water flow generator 38 will be described below.

The water system of the second embodiment of the earlier and later applications is a water system that uses a low water pressure by adjusting the water pressure with a pressure reducing valve 215 to wash sensitive parts of the human body. However, since the rapid opening and closing are performed using the pulsed water flow generator 38, the water system is likely to generate a strong shock wave even at a low water pressure and damage a local part of a human body.
First, the earlier application, and later application, in the low-pressure water system of the second embodiment, as a simple model to illustrate the shock wave of the water system in which the water hammer prevention device such as the accumulator 214 is used, Consider a model water system as shown in FIG.
In the earlier and later applications, the pressure of the water supply pump 240 in the low water pressure system is P, the point A on the downstream side immediately after the solenoid valve 242 that performs rapid opening and closing, and the upstream side immediately before the solenoid valve 242. At point B, the most downstream side of the pipe 241 is an open end (nozzle open) a 243.

When the water flow flowing in the pipe 241 is rapidly opened or closed by the solenoid valve 242 and the speed of the water flow is suddenly changed, a compression wave is generated in the water flow, and an abnormally high water pressure is generated in the pipe 241. May occur.
Since the velocity at which the compression wave propagates through the pipe is as high as 1200 m / sec, the first wave shock wave with the highest energy of the water hammer phenomenon is generated before and after the solenoid valve 242 in a short time within about 0.2 seconds. It is known.

In the model water system shown in FIG. 41, when the solenoid valve 242 is turned on, the valve is rapidly opened, and the water flow is caused to flow in the downstream nozzle direction, the water pressure change at the point A is suddenly fully opened as shown in FIG. When the water stream starts flowing, the density of water at the tip of the water stream increases, and a positive pressure shock wave having high water pressure and high energy is formed.
The water flow is continuously flowing through the pipe 241, and the shock wave of positive pressure or negative pressure (honey or coarse) is instantaneously propagated. It is thought that it is transmitted to the whole water system from when ON / OFF.
Therefore, the shock wave of positive pressure generated at point A by rapidly opening the valve at the time of ON is suppressed in the direction in which the shock pressure becomes coarse due to the interference phenomenon of the accumulator 214, and the shock force represented by a in FIG. It becomes a suppressed shock wave and is discharged as a water flow from the discharge nozzle.

At this time, on the point B side upstream of the solenoid valve 242, the water flow is pulled to the point A side, so that water is separated from the water and a shock wave in a negative pressure direction in which the density is low (coarse) is generated. After passing through the accumulator 214, the energy of the opposite positive pressure is applied, resulting in a shock wave with reduced impact, which propagates upstream. However, the shock wave propagated upstream is not discharged from the downstream nozzle.
The above-mentioned phenomenon in which the impact force is reduced at the points A and B occurs almost simultaneously because the water flow is connected, and when the shock wave passes through the accumulator 214, the impact wave is suppressed at each point. .
On the other hand, when the solenoid valve 242 is turned off and rapidly closed while the water flow is flowing through the pipe 241, as shown in FIG. 43B, the water system of the second embodiment of the earlier application and the later application In FIG. 42, since the discharge nozzle 243 has an open end, when the electromagnetic valve 242 is closed, there is no water flow supplied downstream from the electromagnetic valve 242, so that the water flow is supplied to the nozzle 243 as shown in FIG. Not supplied. Therefore, no water flow is discharged to the local area, and there is no impact.

However, at point B in the pipe 241 on the upstream side of the solenoid valve 242, when the solenoid valve 242 is suddenly closed and turned off, the flowing water flow is pushed to the valve by the inertia of the water and the density is increased to about twice as high. As shown by b, even when the accumulator 214 is used, a reflected wave having a considerably strong positive pressure is generated. However, the high-density reflected wave becomes a shock wave toward the accumulator 214 upstream in the water pipe, and energy is absorbed by the accumulator 214 with time, and the shock wave ends.

When the accumulator 214 receives a steep pressure change from the outside, the rubber bladder ball in which the gas is filled reacts so as to oppose an external force, so that it absorbs energy and has a high positive pressure (Honeyami). And acts as a buffer that moderates the transient phenomena in which the pressure changes abruptly by interfering to raise a high negative pressure (coarse wave).

Therefore, in the earlier application and the second embodiment of the later application, the shock wave that gives a shock to the human body is discharged from the nozzle 41 because the pulse of the pulse water flow generator 38 is turned on and the water flow starts to flow and rises. Only a generated shock wave, and a pulsed washing water discharge including a shock wave whose shock force is suppressed by the accumulator 214 shown in FIG. 42A at the time of rising, is discharged toward the human body.
Regarding the impact of the discharged water on the local part of the human body, the first wave of the shock wave is felt most strongly.
As described above, in the case of the ass washing discharge power that the toilet user feels uncomfortable, it is possible to remotely adjust the output of the gear pump 30, and also by reducing the water pressure and the flow velocity of the feed water gear pump 30. In addition, the strength of the maximum pressure of the shock wave can be reduced, which is effective for reducing the impact feeling.

FIG. 44 shows, in an enlarged manner, the pressure change of the discharge water discharged in the buttocks cleaning process. Discharge having an impact water pressure waveform in which the impact force is suppressed at the rise of each pulse of the pulse water flow generator 38 when the pulse is ON. Water will be discharged from the nozzle.
There is a pulse flow with the rising of the water flow at the ON time of 6 times by one "butt cleaning" command. It will be washed.
Even if the shock wave is reduced in impact force, since the water pressure is higher than the water pressure P of the feed water gear pump 30, the washing power is still high, and it can be used as a discharge washing water flow for washing even the wrinkles in the anus.

However, in the second embodiment of the earlier application and the later application, it is needless to say that the water flow to be cleaned is not only the shock wave component but also the cleaning during the pulse ON period.
In FIG. 7 of the earlier application, the above-described “tail washing” discharge water pressure intensity shown in FIG. 44 is simply represented as a substantially rectangular waveform.
FIG. 39 shows a detailed view of the water system used in the earlier application and the second embodiment of the present application, in which the pressure reducing valve 215 and the accumulator 214 are installed.

Next, it is explained that the waste disposal apparatus according to the earlier application has the following industrial problem, and that the waste disposal apparatus of the second embodiment has been solved by making improvements in the second embodiment of the present application. I do.
That is, the waste disposal apparatus of the earlier application had the following industrial problems.
As shown in FIGS. 1 to 3, since the crushing blade 14 is attached to the rotating shaft 20 of the electric motor 11 at the tip of the long crushing rotating body 13, since the rotational moment is large, the filth and the crushing blade 14 collide. In this case, the amount of work required for the electric motor 11 when pulverizing waste is increased. Therefore, the load applied to the electric motor 11 is large, and it is necessary to use a large motor.
In order to secure clean air for cooling the large-sized electric motor 11, auxiliary air wings 21 for separating air / liquid by a cyclone device 18 to produce clean air for forced air cooling and sending it to the electric motor 11 are required. It is necessary to further increase the rotational load of the refuse and to install the cyclone device 18 in the waste disposal device 49, and the toilet system device becomes large and expensive.

In order to solve the above-mentioned industrial problems, the following measures were taken in the waste disposal apparatus of the second embodiment.
First, in order to reduce the load applied to the electric motor 11, the waste is previously formed into a small lump by the coarse crushing plate 205, and the rotating shaft 20 of the electric motor 11 is not used without using the long crushing rotating body 13. The crushing blade 14 is directly attached to the crusher, and the crushing blade 14 is formed into a shape having a small turning radius to reduce the rotational moment and work during crushing. Second, a simple structure without using a large cyclone device 18 The gas / liquid separation was carried out to obtain a small waste disposal device.
Thirdly, the propeller fan 203 having a strong suction force can be used, and in another embodiment, a small-sized waste disposal apparatus using a sirocco fan 12 which is silent and has a high space utilization rate is improved.
Fourth, the electromagnetic discharge valve 211 is used as a part of the wall of the waste crushing tank 208, and the electromagnetic discharge valve 211 is closed at the time of depressurization to ensure the negative pressure in the decompression chamber 202.
Fifth, in the standing urination process, the urine around the urinal bounces, and a part of the urine diffuses and scatters. Prevented.

Hereinafter, the waste disposal apparatus 49 of the second embodiment will be described in detail.
The configuration of the waste disposal apparatus 49 of the second embodiment includes a decompression chamber 202 and a waste discharge chamber 210 as shown in FIGS.
The decompression chamber 202 has a filth introduction unit 204 for introducing filth from the toilet 48 into the filth treatment device 49, and a gas / liquid separation unit 206 at the lower end of the filth introduction unit 204. A suction means for the propeller fan 203 or the sirocco fan 12 is attached to the shaft 20, and a waste crushing blade 14 is attached to the tip of the rotating shaft 20. Then, it is structured to grind the filth.
In the second embodiment, the decompression chamber 202 and the waste discharge chamber 210 are connected by a partition 201, and an opening at the upper part of the partition 201 through which the discharged airflow that has cooled the streak radiating fins 216 flows into the waste discharge chamber 210. 218, a wastewater discharge port 212 is provided below the partition 201, and an electromagnetic discharge valve 211 is installed in connection with the wastewater discharge port 212. When the electromagnetic discharge valve 211 is opened, the lower part of the decompression chamber 202 is opened. The structure is such that waste water flows out of the waste grinding tank 208 through the waste discharge chamber 210 to the sewer pipe 26 along the inclined path, and is transferred to the sewer pipe 26.

The first problem to be solved in the second embodiment of the present application is to reduce the load of pulverization.
As shown in FIGS. 25 and 26 using a propeller fan and FIG. 27 using a sirocco fan as another example, when excreted feces are introduced into the waste disposal device 49 from the waste introduction part 204 and dropped. Then, the dirt is made to collide with the coarse crushing plate 205 to form a small filth lump, and then the rotary crushing blade 14 is rotated in the crushing tank 208 to become filth water in which fine filth particles, washing water and air are mixed. As described above, the coarse grinding is performed in advance so that a large load during the grinding is not applied to the electric motor 11.

A short-length crushing blade 14 shown in FIGS. 25 to 29 is attached to the tip of the rotating shaft 20 of the electric motor 11 and rotates in the trash crushing tank 208 to collide with the small refuse lump described above. Crushed to reduce the rotational moment.
The odor control structure 69 at the lower part of the toilet bowl stores only a certain amount of water, but when more water flows from the toilet bowl, it flows into the waste crushing tank 208 of the waste disposal apparatus 49 and is collected. When the lump flows into the grinding tank 208, a lot of water is already present in the waste grinding tank 208.

Next, the waste introduction part 204 and the coarse crush plate 205 of the waste disposal apparatus 49 will be described.
The waste introduction part 204 of the decompression chamber 202 is airtightly connected to the waste discharge port 9 below the waste storage 8 of the toilet, and is stored together with the washing water in the odor prevention structure 69 below the waste storage 8 of the toilet. The dirt is decompressed by the rotation of the suction means in the decompression chamber 202 to a pressure difference exceeding the water layer thickness of the odor control structure 69, and when the pressure becomes negative, the water layer of the odor control structure 69 is broken and the atmospheric pressure of the outside air Then, the waste falls along with the washing water and the air into the waste introduction section 204 of the waste disposal apparatus 49 by a suction airflow.
As shown in FIGS. 25 to 27, a plurality of coarse crushing plates 205 are provided inside the waste introduction part 204, and the large lump of sewage after defecation falls downward together with the washing water and collides with the coarse crushing plate 205. Then it breaks down into a little litter. The waste mass and the washing water hit the sliding plate 207 which is inclined downward at the lowermost part of the waste introducing portion 204, slide down on the surface of the sliding plate 207, and fall into the waste crushing tank 208.

A description will be given of a second problem to be solved by the second embodiment, which is a structure capable of achieving a gas / liquid separation action with a simple structure.
As shown in FIGS. 25 to 27, the suction airflow is sucked through the waste introduction part 204 of the waste disposal apparatus 49. Since the air is sucked by the rotation of the suction means provided in the upper part of the decompression chamber 202, the suction airflow is turned into a U-shape at the lower end of the waste introduction part 204 and is sucked up.
When the direction of the suction airflow is sharply bent at the tip of the waste introduction part 204, the waste component and the washing water component mixed in the suction airflow are shaken off by centrifugal force, and the same as when the cyclone device 18 is used. A gas / liquid separation phenomenon occurs in which air separates from lumps and washing water.
Therefore, the suctioned airflow that has been subjected to the gas / liquid separation is a clean airflow that is free of dirt components.
Since the gas / liquid separation is performed after finely crushing the filth in the filth crushing groove 16 of the previous application, it was difficult to separate fine solids without using a full-scale cyclone device 18. In this embodiment and the other embodiments, before the filth is finely crushed, gas / liquid separation is performed at the stage where the filth is coarsely crushed into small-sized filth lump in advance. The gas / liquid separation unit 206 having a simple structure that can be changed only at the tip of the unit 204 can efficiently remove waste lump components and liquid components from the suction airflow and can be installed in the cyclone device 18 as in the embodiment of the earlier application. There is no need for the air extraction pipe 22 and the auxiliary wing 21 that have been used. The air flow can be a clean air flow used for cooling the electric motor 11.
The air that is bent by the gas / liquid separation unit 206 of the waste introduction unit 204 and strongly sucked by the suction unit becomes a rising air current, collides with the rotors (203 and 219) of the suction unit, and generates air molecules at the angle of the rotor. Is subjected to a force that is strongly pushed out, and becomes an exhaust airflow.
As described above, the dirt component and the liquid component can be efficiently removed from the suction airflow by the gas / liquid separation unit 206 having a simple structure without using the large and expensive cyclone device 18, and the clean air flow can be taken out. Therefore, the waste disposal equipment could be made smaller.

The third problem to be solved by the present application is to devise a structure that can use either the sirocco fan 12 or the propeller fan 203 as the suction means.

That is, an example in which the propeller fan 203 is used will be described below.
The propeller fan 203 is an inexpensive suction means that strongly pushes out a straight airflow in the direction of the rotating shaft 20 and has strong exhaust power.
For this reason, the propeller fan 203 is not optimal for applications in which the airflow is bent at a right angle, and the sirocco fan 12 that can easily bend the exhaust direction is generally used. However, it is expensive.
In the waste disposal apparatus 49 of the second embodiment, as shown in FIG. 25, FIG. 26, FIG. 28, and FIG. 29, the streak radiating fins 216 are provided at positions where the propeller fan 203 receives the straight exhaust airflow at right angles. Thus, the airflow was bent at a right angle to flow toward the waste discharge chamber. As a result, the propeller fan 203 having the straight exhaust air can be used.
In the examples shown in FIGS. 26, 28 and 29, the propeller fan 203 is attached to the rotating shaft 20 of the electric motor 11, and the exhaust airflow strongly pushed by the rotation of the propeller fan 203 is supplied to the upper part of the decompression chamber 202 by the electric motor. The motor 11 collides with the radiating fins 216 on which the motor 11 is installed, and performs heat exchange on the surface of the radiating fins 216 to cool the heated electric motor 11.
The shape of the streak-shaped heat radiation fins 216 is such that a plurality of lines of fins arranged in a streak shape having a large surface area are formed in order to efficiently exchange heat on the surface.
The exhaust airflow generated by the rotation of the suction means is received by the streak radiating fins 216, and the streak-like fins are installed so that the exhaust airflow can pass through the opening 218 of the waste discharge chamber 210. It flows according to the streaks of the radiating fins 216 and enters the waste discharge chamber 210 through the opening 218 provided at the upper part of the partition 201.

27, FIG. 30, and FIG. 31 are assembly drawings of an example using the sirocco fan 12, in which a radiation fin 222 is provided in a space inside a cylindrical rotor 219 of the sirocco fan 12. The electric motor 11 attached in close contact with the support 225 is installed in a state where the electric motor 11 is attached to the support 225, and heat is exchanged by the radiation fins 222 in the suction airflow of the sirocco fan 12 to efficiently cool the electric motor 11. As a result, the space utilization rate of the waste disposal apparatus 49 could be improved.
A heat radiation fin 222 in which a large number of plate-like fins are arranged in a cylindrical shape is closely attached to a casing 226 of the electric motor 11, and is installed in the space of the sirocco fan rotor 219, and is provided in the space of the sirocco fan rotor 219. When the air rotates to generate a suction airflow, the suction airflow cools the electric motor 11 and the radiation fins 222 and rises, and enters the waste discharge chamber 210 through the opening 218 provided at the upper part of the partition wall 201.
As shown in FIGS. 27, 30, and 31, the electric motor 11 for rotating the sirocco fan 12 is attached to a support 225 fixed to the wall of the decompression chamber 202, and has a semi-cylindrical sirocco fan blade. The electric motor 11 is mounted at a position where there is no problem even if the 219 rotates.
This structure is located inside the narrow decompression chamber 202 of the waste disposal apparatus 49 and has a very high space utilization rate.

The fourth of the problems of the second embodiment is the waste crushing tank 208 and the electromagnetic discharge valve 211, which will be described below.
When the first-stage suction drying process is started, the rotation of the electric motor 11 is started, and when the suction drying is started by the rotation of the suction means, the sewage that has slipped into the sewage crushing tank 208 is removed after the previous toilet user. The washing water and the discharge water used in the defecation assist process are already accumulated in the crush tank 208, and the washing water used in the ass washing after the defecation is added, and the electric motor 11 is rotated in the crush tank 208. The crushing blade 14 that rotates at a high speed with the force collides and cuts with a small lump of filth, and is crushed into fine filth particles.
At this time, the large filth litter that has been defecation is previously crushed into a somewhat small lump by the collision with the coarse crushing plate 205 at the filth introduction unit 204, and is crushed by the collision with the rotating crushing blade 14 many times. Is performed, only a small work load is applied to the electric motor 11.
The crushing blade 14 is a knife edge and is made of a hard metal such as phosphor bronze or stainless steel. The crushing blade 14 is rotated horizontally to slice and cut the waste mass. Although the crushing blade 14 collides with the filth many times, the length of the crushing blade 14 is designed to be small and the turning radius small so as not to cause a large rotational moment. Is small. In addition, the draining noise is reduced by horizontally rotating the crushing blade 14.
The bottom of the waste crushing tank 208 may have a V-shape so that the crushing blade 14 can easily rotate and collide with the waste lumps. However, consideration must be given to a structure that facilitates drainage of waste water.

The fifth problem of the second embodiment is that when a negative pressure is generated in the decompression chamber 202, the decompression chamber 202 and the waste discharge chamber 210 are connected to each other in order to ensure the negative pressure and to ensure the suction stimulation in the defecation assist. The electromagnetic discharge valve 211 is installed at the waste water discharge port 212 of the partition wall 201.
This structure is a structure of the waste disposal apparatus 49 of the second embodiment shown in FIGS. 25 to 27 and another embodiment. If the electromagnetic discharge valve 211 is not provided, the suction means is rotated by the rotation of the electric motor 11. Then, a phenomenon occurs in which air from the sewer pipe side flows backward through the wastewater discharge port 212 to the waste discharge chamber 210, and the decompression chamber 202 cannot reach a sufficient negative pressure even if the suction means is rotated.
In order to eliminate such a phenomenon and obtain a sufficient suction capacity, an electromagnetic discharge valve 211 is attached to the waste water discharge port 212 of the partition wall 201 to create a negative pressure in the decompression chamber 203, or to perform suction urination or suction stimulation, In the suction drying process, when the electromagnetic discharge valve 211 is closed and the suction means is rotated, the backflow of air from the sewer pipe 26 can be prevented.

However, by providing the electromagnetic discharge valve 211 on the partition wall 201, in order to discharge the waste water from the waste crushing tank 208 to the drain 26, the power supply of the electromagnetic actuator 209 of the electromagnetic discharge valve 211 is turned on and the valve is opened. Thus, the waste water is taken out and discharged to the sewer pipe 26.
When the wastewater is discharged from the waste crushing tank 208 to the sewer pipe 26, the electromagnetic discharge valve 211 is only opened, and in order for the wastewater to naturally flow from the waste crush tank 208 toward the sewer pipe 26, the electromagnetic discharge valve 211 is required. Before opening, the air pressure upstream and downstream of the electromagnetic discharge valve 211 needs to be equalized.
If the air pressure is different between the upstream side and the downstream side of the electromagnetic discharge valve 211, air flows between the decompression chamber 202 and the sewer pipe 26, and the waste water flows in the direction of the sewer pipe 26 along the descending slope of the bottom for a short time. This is because sometimes it does not flow well.

As shown in FIGS. 25, 26, and 27, the valve portion of the electromagnetic discharge valve 211 in a closed state is a part of the wall of the waste crushing tank 208, and the opening of the electromagnetic discharge valve 211 is When the electromagnetic discharge valve 211 is opened, most or all of the waste water in the waste crushing tank 208 flows out to the bottom of the waste discharge chamber 210 when the waste water outlet 212 including the bottom of the waste tank 208 is closed. Therefore, the wastewater flow is designed so that there is almost no obstacle on the way, and the wastewater flows into the wastewater discharge pipe 213 inclined downward toward the sewer pipe 26.
The filth is crushed into fine filth particles, has moisture, and has a lubricating effect, so that it has a structure that can operate and open and close without impairing the function as an electromagnetic valve.
If the electromagnetic discharge valve 211 uses a liquid electromagnetic valve having a diameter of about 20 mm or more, waste water can be discharged in a short time.
As the type of the electromagnetic discharge valve 211, an electromagnetic valve such as a ball valve, a butterfly valve, a slide gate valve, and a flange valve can be used.
25, 26, and 27 show examples using a slide gate valve.
25, 26, and 27 show an example in which the electromagnetic actuator 209 of the electromagnetic discharge valve 211 is installed inside the waste discharge chamber 210, but it is also easy to install the electromagnetic actuator 209 outside the waste discharge chamber 210.

The discharged airflow that has entered the waste discharge chamber 210 enters the waste water discharge pipe 213 installed at the lower part of the waste discharge chamber 210, and the waste water in the waste water discharge pipe 213 is inclined downward by the waste water discharge pipe 213. , And is transferred to the sewer pipe 26 by the flow of the discharged airflow. The discharge airflow is also discharged to the sewer pipe 26.
When the power is OFF, the valve body of the electromagnetic discharge valve 211 is closed, waste is introduced into the waste crush tank 208, and the waste lumps are rotated by the rotation of the grinding blade 14 attached to the tip of the electric motor 11. During the pulverization, a negative pressure is created in the decompression chamber 202, and in the suction urination, suction stimulation, suction drying, and post-cleaning processes, the electromagnetic discharge valve 211 is opened or closed according to an appropriate sequence. .

Only when the waste water is discharged to the sewer pipe 26, as described above, the upstream and downstream of the electromagnetic discharge valve 211 are equal in pressure or almost equal in pressure. The valve body is opened, and the waste water naturally flows out of the waste crush tank 208 to the sewer pipe 26 via the waste discharge chamber 210 to the sewer pipe 26. Thereafter, when the suction means rotates in the post-washing process to send the discharged airflow to the waste discharge chamber 210, the wastewater is flushed to the sewer pipe 26 by the flow of the airflow, and at the same time, the post-wash water is discharged from the waste pool 8 to the waste crushing tank 208. The accumulated waste water can be washed off the waste flow path with fresh washing water to keep the valve body of the electromagnetic discharge valve 211 moist.

A sixth problem of the toilet system using the waste disposal apparatus of the second embodiment and the other embodiments is to prevent urine water from splashing around the toilet in the standing urinal process and becoming dirty.
When urinating in a standing position, urine water released from the urinary tract draws a parabola and falls on the odor-stopping water surface 250 of the filth pool 8, and sewage jumps on the water surface, or parabolic urine water is not necessarily a single water column. In addition, there is also urine water that partially spreads out in a conical shape and falls around the toilet, and the area around the toilet is contaminated with urine water or bounce water.
The odor control structure 69 of the toilet according to the second embodiment and other embodiments of the present application uses the structure shown in FIG.
When the suction means is rotated to reduce the pressure in the decompression chamber 202 to a negative pressure, most of the water layer serving as an odor control is sucked and dropped into the crushing tank 208. If the suction means continues to rotate during urination, urine water will not accumulate in the odor control structure 69 and will not bounce.
Since the outside air is continuously sucked from the toilet bowl 8, the suction air current sucks the splash of urine water into the crushing tank 208 and does not scatter outside the toilet.
That is, as shown in the standing urine process sequence of the present application in FIG. 53, if the suction means is continuously rotated until the urination is completed from the start of urination until the urination is completed, the urine water which spreads in a conical shape and scatters is formed. In part, contamination around the toilet bowl can be eliminated.
Further, when the suction means rotates and the odor preventing water layer is sucked into the waste crushing tank 208, the water of the odor preventing structure 69 becomes completely invisible when viewed from above the filth reservoir 8. If the odor prevention structure 69 is designed, it is more effective to completely prevent bouncing.
In order to prevent the toilet area from being unsanitary in the standing urination process, as shown in a sequence in FIG. 51, the entrance to the toilet room is sensed, and the toilet seat 3 is not seated. When the button is flipped upward, the limit switch (not shown) installed in the toilet seat bearing 4 of the toilet seat is turned on, the microcomputer determines that the process is a standing urinal process, and automatically turns off the electromagnetic discharge valve. Then, the electric motor 11 is turned on. When the suction means rotates to start sucking the ambient air from the waste pool 8 of the toilet, urination is completed, urination is completed, and the toilet seat 3 is lowered to the original upper position of the toilet bowl. The limit switch is turned off, and the next wastewater discharge sequence is started.

The toilet process sequence of the present application using the waste disposal apparatus 49 of the second embodiment and the other embodiment is almost the same as the sequence shown in FIGS. In the defecation assist process, the suction drying process, the hot air drying process, the process of sucking and dropping filth into a crushing tank, the filth crushing process, the discharging process of filth water to a sewer pipe, and the pre / post-cleaning process, FIG. Slight changes are required, as shown in (1).

First, since the present application is a water-saving toilet system, for the contamination of the toilet surface, if defecation is performed in a state where the toilet surface is dry, dirt may stick to the toilet surface. In order to prevent the case where it is difficult to easily wash off in the step of, the “pre-cleaning” process shown in FIG. 52 is performed, and the fourth solenoid valve 63 is provided on the toilet surface before starting the toilet process. Is opened, and about 1 L of washing water is flowed from the toilet water pipe or pipe to keep it wet.
Toilet water pipes or pipes are provided so that when the user senses entry into the toilet room, flush water spreads from the upper part around the toilet to the inner surface of the toilet bowl.
In addition, when the human sensor detects that the user has left the toilet room after the entire toilet process has been completed, the washing water is placed on the inner surface of the toilet bowl in the same manner as described above as a fourth post-wash process. When the solenoid valve 63 is opened, about 3 L of flush water flows from the toilet water pipe or pipe to clean the toilet surface and at the same time to wash the waste passage of the waste treatment device 49 and to improve the lubricity of the valve body of the electromagnetic discharge valve 211. Water is stored in the waste crushing tank at a water level that maintains it.

Next, the sequence of the toilet system using the waste disposal apparatus 49 according to the second embodiment and another embodiment will be described by taking as an example a process of discharging waste water to the sewer pipe 26 from defecation by the defecation assist process. . For details, refer to the sequences shown in FIGS.
In the defecation assist sequence, "straight hot water" of the standard condition cleaning of the bidet cleaning process shown in Fig. 54 and "pulse water flow cleaning" of the buttocks cleaning of Fig. 56 are also applied to the warm water stimulation of the defecation assist. After confirming whether these two processes are being used for bidet washing, buttocks washing, or in the process of assisting defecation, the system was changed to a method of incorporating them into the warm water stimulation sequence of assisting defecation.

In addition, as shown in the defecation assist process sequence of FIG. 55, a sequence in which “straight warm water stimulation”, “pulse water flow stimulation”, and “suction stimulation” are selected and commanded remotely at the start of the defecation assist process did.
In other words, it is also possible to select "suction stimulation" from the beginning,
The electromagnetic discharge valve 211 of the waste disposal apparatus 49 is turned off and the valve is closed, the electric motor 11 is turned on, and the propeller fan 203 or the sirocco fan 12 as a suction means is rotated to exhaust air from the waste pool 8 of the toilet. When the toilet user sits with both knees together, the electromagnetic discharge valve 211 of the decompression chamber 202 is closed, so that the negative pressure in the decompression chamber 202 and the waste pool 8 is secured. Toilet users felt a negative pressure suction stimulus in the rectum and anus, and improved their defecation assist process, which increased their instinct and allowed them to select a process that could perform defecation assist. By making it possible to select a suction stimulus from the beginning without going through warm water stimulation, it is possible to enhance the defecation of defecation in a non-contact manner, and it is also effective for persons with diseases such as cut hemorrhoids.

In the structure of the above-mentioned toilet seat and toilet using the waste disposal apparatus 49 shown in FIGS. 26 and 27 of the second embodiment and another embodiment, when the two kneecaps are put together on the toilet seat, FIG. As shown in the image diagram in FIG. 33, the space created by the thighs becomes a substantially air-tight space. Therefore, when the electric motor 11 rotates and the suction means sucks air at high speed, the substantially air-tight space is decompressed. A negative pressure suction stimulus is felt without contacting the anus and the rectum.
When gas near the anus of the rectum is sucked into the anus, the toilet user feels strong defecation and encourages independent defecation. For a person with inadequate instinct, the warm water stimulation of the straight stream, the pulsed stream, and the suction stimulation can be repeated any number of times. As described above, in the defecation assist process sequence in FIG. 55, when the user's feelings are enhanced by the aforementioned stimulus and the self-sustaining defecation is performed, the process proceeds to the buttocks cleaning process.

The buttocks cleaning process sequence shown in FIG. 56 occurs when the toilet is seated in a relaxed position and the pulse water flow generator 38 is turned on to rapidly open the water channel and flow the water flow, as shown in FIG. The shock wave is converted into a shock wave in which the impact force is suppressed by the interference of the accumulator 214, and includes the suppressed impact of six times with a single pulse water flow discharge command as in the hot water discharge pulse flow shown in FIG. The pulsed hot water flow is discharged toward the anus, and the inside of the anal wrinkle can be sufficiently washed. You can repeat the ass washing many times.
Of course, a person who feels a strong impact can adjust the discharge force of the gear pump 30.

Next, when the process proceeds to the first-stage suction drying process shown in FIG. 57, it is confirmed that the power of the electromagnetic discharge valve 211 is OFF. If the power is ON, the power is turned OFF and the valve is closed. When the motor 11 is turned on, the pressure in the decompression chamber 202 is reduced to a negative pressure, and the air in the waste pool 8 of the toilet is sucked. As shown in FIG. An airflow is generated that is sucked into the toilet from between the thighs.
The suction airflow passes through the anterior part from the anterior genital area, reaches the fan of the suction means installed in the waste disposal device 49 from the waste outlet 9 of the toilet bowl, passes through the waste discharge chamber 210, and is discharged to the sewer pipe 26.
At this time, most of the water that wets the pubic area and anal area is in the form of water droplets attached to or adsorbing to the pubic hair and skin. And is mechanically removed.

During the suction drying process, which is the first drying process, when the pressure in the decompression chamber 202 of the waste disposal device 49 becomes a negative pressure exceeding the pressure difference of the water layer thickness of the odor control structure 69, the odor control structure 69 is activated. The water layer is broken, and the dirt and the cleaning water in the dirt pool 8 of the toilet bowl are dropped into the dirt introduction part 204, and the large dirt mass collides with the coarse crushing plate 205 to become a small lump of dirt and the sliding water 207 together with the cleaning water. To fall into the waste crushing tank 208.
In the filth crushing tank 208, the crushing blade 14 attached to the tip of the rotary shaft 20 of the electric motor 11 is rotating at high speed, and the filth lump becomes filth water mixed with washing water and air.
Since the present application does not use toilet paper, it is possible to use the crushing blade 14 to turn the waste into highly fluid waste water mixed with fine particles.

In the water-saving toilet system of the present application, in the above-mentioned waste crushing process, if there is too little liquid component in the crushing tank 208, there is a possibility that sewage cannot be crushed well. In order to avoid such troubles, a water level gauge is installed in the crushing tank 208, the crushing process is started only when there is a liquid component above a certain water level, and when the water level does not reach the certain water level, the fourth step is performed. It is also a good method to open the electromagnetic valve 63 and inject water into the crushing tank 208 to increase the liquid component to a certain level.
The process of turning the waste into waste water is performed during the first-stage suction drying, as shown in FIG.

Next, the process proceeds to a hot air drying process, which is a second-stage drying process shown in FIG. 58, in which hot air is blown out from a nozzle toward a local portion, and moisture remaining on the skin surface is dried with the hot air.
In order to prevent the stench of the filth pool 8 from coming up on the face, the fan of the suction means is rotated at a low speed at the same time as the hot air is discharged from the nozzle 57, so that the speed is slightly lower than the hot air discharge speed. Air is suctioned by suction means.
When the second-stage hot air drying process is completed and the rotation of the electric motor 11 is stopped, the air flows from the toilet and the sewer pipe into the decompression chamber 202, and the waste discharge chamber 210 becomes atmospheric pressure. When the valve 211 is opened, the waste water spontaneously flows out, flows toward the drain 26 along the slope of the pipe, and the waste water discharge sequence shown in FIG. 59 is started.
In the drying process, when the toilet user feels that the area is completely dry, he issues a command of "end", stands up, prepares clothes, and exits the toilet room.
When an instruction of “end” is issued and the user leaves the toilet room and the motion sensor detects “exit”, the post-cleaning process of FIG. 52 described above is started.

The process sequence of discharging waste water according to the second embodiment and the other embodiment shown in FIG. 59 will be described. When the rotation of the electric motor 11 is automatically turned off, the air flows in from the toilet and the sewer pipe. Then, the decompression chamber 202 becomes the atmospheric pressure, the upstream and downstream of the electromagnetic discharge valve 211 have the same pressure of the atmospheric pressure. The water flows along the descending slope, and most or all of the wastewater is discharged to the drain 26.
The power of the electromagnetic discharge valve 211 is automatically turned off again in about 10 seconds, and the electromagnetic discharge valve 211 is closed, thereby completing the waste discharging process.

Next, when the toilet user exits the toilet room and the human sensor detects the exit, the post-washing process sequence shown in FIG. 52 starts, the electric motor 11 is turned on for 5 seconds, and the suction means rotates, The waste air in the sewer pipe 26 is discharged by the flow of the air with the discharged air flow, the air in the toilet is replaced with fresh outside air, and about 3 L of post-wash water is used to wash the inner surface of the toilet from the fourth solenoid valve 63. I do.
Part of the washing water accumulates in the odor control structure 69 at the outlet of the toilet, and works to prevent the bad odor from the waste disposal device 49 from flowing back into the toilet room.
Further, the remaining amount of the washing water for the post-washing flows into the waste disposal device 49, flows to the crushing tank 208, wets the valve body of the electromagnetic discharge valve 211, and also serves to maintain the lubrication of the operating surface of the valve.

The description of the sequence of the toilet process is completed above, but the hot water and hot air standby sequence is the same as that in FIGS. 16 and 17 of the earlier application, and thus the description is omitted.

The present invention is not limited to the above-described embodiment at all, and various suction means and a high degree of vacuum operated by the aircraft can be easily obtained outside the toilet system without departing from the gist of the present invention. In an environment or the like, it is of course possible for a person skilled in the art to easily carry out the same invention purpose as in the present application by replacing the suction unit of the present application with the depressurized state of the decompression chamber.

1. It assists defecation using the mechanism of the suction toilet of the present application, so it is not easy to defecate, and it becomes a toilet friendly to elderly people with abdominal muscle weakness, disabled people, not only general household toilets, It can also be used in toilet systems used by an unspecified number of people, such as hospitals, nursing homes, highway service areas, transportation stations such as trains and aircraft, and vehicles.
2. The possibility of pathogenic harmful bacteria spreading through the toilet has been fundamentally solved by eliminating the "wiping the ass" toilet operation. The toilet system according to the present invention is an effective infectious disease countermeasure for a catering center, a food processing industry, a hospital facility, and the like. It is also considered to contribute to a society that is friendly to the elderly and the disabled and is widely accepted.
3. By eliminating the need for toilet paper and finely crushing the waste, the waste can be discharged into the sewer pipe with a small amount of water without any problem.
4. In the standing urination process, it was possible to prevent urine water splashing around the toilet and "splashing of odor-stopping water" and improve sanitary conditions around the toilet.
5. Without using expensive and large-sized vacuum equipment, almost equivalent or higher toilet function was obtained, and it became a toilet type that could be introduced for home use.

First, in order to reduce the load applied to the electric motor 11, the waste is previously formed into a small lump by the coarse crushing plate 205, and the rotating shaft 20 of the electric motor 11 is not used without using the long crushing rotating body 13. The crushing blade 14 is directly attached to the crusher, and the crushing blade 14 is formed into a shape having a small turning radius to reduce the rotational moment and work during crushing. Second, a simple structure without using a large cyclone device 18 The gas / liquid separation was carried out to obtain a small waste disposal device.
Thirdly, the propeller fan 203 having a strong suction force can be used, and in another embodiment, a small-sized waste disposal apparatus using a sirocco fan 12 which is silent and has a high space utilization rate is improved.
Fourth, the electromagnetic discharge valve 211 is used as a part of the wall of the waste crushing tank 208, and the electromagnetic discharge valve 211 is closed at the time of depressurization to ensure the negative pressure in the decompression chamber 202.
Fifth, in the standing urination process, a urination process has been developed to prevent urine water from splashing around the toilet bowl and preventing some of the urine water from diffusing and scattering. Prevented hygiene.

27, FIG. 30, and FIG. 31 are assembly drawings of an example using the sirocco fan 12, in which a radiation fin 222 is provided in a space inside a cylindrical rotor 219 of the sirocco fan 12. The electric motor 11 attached in close contact with the support 225 is installed in a state where the electric motor 11 is attached to the support 225, and heat is exchanged by the radiation fins 222 in the suction airflow of the sirocco fan 12 to efficiently cool the electric motor 11. As a result, the space utilization rate of the waste disposal apparatus 49 could be improved.
A heat radiation fin 222 in which a large number of plate-like fins are arranged in a cylindrical shape is closely attached to a casing 226 of the electric motor 11, and is installed in the space of the sirocco fan rotor 219, and is provided in the space of the sirocco fan rotor 219. When the air rotates to generate a suction airflow, the suction airflow cools the electric motor 11 and the radiation fins 222 and rises, and enters the waste discharge chamber 210 through the opening 218 provided at the upper part of the partition wall 201.
As shown in FIGS. 27, 30, and 31, the electric motor 11 for rotating the sirocco fan 12 is attached to a support 225 fixed to the wall of the decompression chamber 202, and the semi-cylindrical sirocco fan rotor 219 rotates. The electric motor 11 and the radiation fins 222 were mounted inside the sirocco fan rotor 219 which would not hinder the operation .
This structure is located inside the narrow decompression chamber 202 of the waste disposal apparatus 49 and has a very high space utilization rate.

A sixth problem of the toilet system using the waste disposal apparatus of the second embodiment and the other embodiments is to prevent urine water from splashing around the toilet in the standing urinal process and becoming dirty.
When urinating in a standing position, urine water released from the urinary tract draws a parabola and falls on the odor-stopping water surface 250 of the filth pool 8, and sewage jumps on the water surface, or parabolic urine water is not necessarily a single water column. In addition, there is also urine water that partially spreads out in a conical shape and falls around the toilet, and the area around the toilet is contaminated with urine water or bounce water.
The odor control structure 69 of the toilet according to the second embodiment and other embodiments of the present application uses the structure shown in FIG.
When the suction means is rotated to reduce the pressure in the decompression chamber 202 to a negative pressure, most of the water layer serving as an odor control is sucked and dropped into the crushing tank 208. If the suction means continues to rotate during urination, urine water will not accumulate in the odor control structure 69 and will not bounce.
Since the outside air is continuously sucked from the toilet bowl 8, the suction air current sucks the splash of urine water into the crushing tank 208 and does not scatter outside the toilet.
That is, as shown in the standing urine process sequence of the present application in FIG. 53, if the suction means is continuously rotated until the urination is completed from the start of urination until the urination is completed, the urine water which spreads in a conical shape and scatters Can be prevented from contaminating around the toilet .
Further, when the suction means rotates and the odor preventing water layer is sucked into the waste crushing tank 208, the water of the odor preventing structure 69 becomes completely invisible when viewed from above the filth reservoir 8. If the odor prevention structure 69 is designed, it is more effective to completely prevent bouncing.
In order to prevent the toilet area from being unsanitary in the standing urination process, as shown in a sequence in FIG. 51, the entrance to the toilet room is sensed, and the toilet seat 3 is not seated. When the button is flipped upward, the limit switch (not shown) installed in the toilet seat bearing 4 of the toilet seat is turned on, the microcomputer determines that the process is a standing urinal process, and automatically turns off the electromagnetic discharge valve. Then, the electric motor 11 is turned on. When the suction means rotates to start sucking the ambient air from the waste pool 8 of the toilet, urination is completed, urination is completed, and the toilet seat 3 is lowered to the original upper position of the toilet bowl. The limit switch is turned off, and the next wastewater discharge sequence is started.

In addition, as shown in the defecation assist process sequence of FIG. 55, a sequence in which “straight warm water stimulation”, “pulse water flow stimulation”, and “suction stimulation” are selected and commanded remotely at the start of the defecation assist process did.
In other words, it is also possible to select "suction stimulation" from the beginning,
The electromagnetic discharge valve 211 of the waste disposal apparatus 49 is turned off and the valve is closed, the electric motor 11 is turned on, and the propeller fan 203 or the sirocco fan 12 as a suction means is rotated to exhaust air from the waste pool 8 of the toilet. When the toilet user sits with both knees together, the electromagnetic discharge valve 211 of the decompression chamber 202 is closed, so that the negative pressure in the decompression chamber 202 and the waste pool 8 is secured. Toilet users felt negative stimulus of suction in the rectum and anus, improved their defecation, and improved the defecation assist process to select a process that can perform defecation assist. By making it possible to select a suction stimulus from the beginning without going through warm water stimulation, it is possible to enhance the defecation of defecation in a non-contact manner, and it is also effective for persons with diseases such as cut hemorrhoids.

1. It assists defecation using the mechanism of the suction toilet of the present application, so it is not easy to defecate, and it becomes a toilet friendly to elderly people with abdominal muscle weakness, disabled people, not only general household toilets, It can also be used in toilet systems used by an unspecified number of people, such as hospitals, nursing homes, highway service areas, transportation stations such as trains and aircraft, and vehicles.
2. The possibility of pathogenic harmful bacteria spreading through the toilet has been fundamentally solved by eliminating the "wiping the ass" toilet operation. The toilet system according to the present invention is an effective infectious disease countermeasure for a catering center, a food processing industry, a hospital facility, and the like. It is also considered to contribute to a society that is friendly to the elderly and the disabled and is widely accepted.
3. By eliminating the need for toilet paper and finely crushing the waste, the waste can be discharged into the sewer pipe with a small amount of water without any problem.
4. In the standing urination process, splashing of urine around the toilet and "splashing of odor-stopping water" could be prevented, and sanitary conditions around the toilet could be improved.
5. Without using expensive and large-sized vacuum equipment, almost equivalent or higher toilet function was obtained, and it became a toilet type that could be introduced for home use.

The present invention provides a suction-type flush toilet system including a butt washing hot water nozzle and a hot air drying nozzle, wherein a suction means rotated by an electric motor, a waste crusher, a gas / liquid A sewage treatment device with a separation mechanism is connected, assists with defecation including suction stimulation, suction drying that cleans the local area with pulsed water flow and dries in a short time, and a urinal with standing urine using suction power The present invention relates to a defecation assist suction type flush toilet system having a function of preventing peripheral contamination.

It is known that high concentrations of pathogenic bacteria can be found in the stool of patients suffering from infectious harmful bacteria (norovirus, rotavirus, Salmonella, O-157, Escherichia coli, etc.). If a person suffering from infectious harmful bacteria uses a conventional flush toilet and a toilet inside or outside the handwashing facility, hands and fingers contaminated with pathogenic bacteria after stool is wiped with toilet paper, various switches with flush fingers, flush knobs, Many cases have been reported from the Ministry of Health, Labor and Welfare, the National Institute of Infectious Diseases, etc., which caused secondary contamination by touching the toilet lid, hand wash faucet, common towel, door knob, door lock, patient's clothes, etc., and spread to food poisoning. . It has also been reported that elderly people die of heart disease, cerebral hemorrhage or vascular insufficiency such as cerebral infarction when breathing in the toilet. Defecation and wiping the buttocks after defecation are very difficult for the elderly and those with disabilities such as hemiplegia due to brain disorders.Severely ill persons must have their caregivers wipe the local area after defecation. There is also the problem of an aging society. Another problem is that the urinal in the standing position becomes unsanitary around the toilet. In view of this fact, there is a long-awaited need for a toilet that has a mechanism for assisting smooth defecation when a flush toilet is used and that does not require the operation of wiping the buttocks with toilet paper.

This application is a patent application in which the same inventor as in Patent Document 14 is improved with different solutions to the same object of the invention.

The conventional flush toilet device provided with the ass washing hot water nozzle and the hot air drying nozzle has the following problems.
That is, the first problem is that when the anus is wiped off with toilet paper after washing the local part with the conventional hot water shower cleaning, the hot water shower cleaning is often incomplete so that the residue of dirt comes to the toilet paper. .
The second problem is that in the method of drying by blowing dry hot air to a local area after washing with a hot water shower, it is necessary to take a long time to dry the hot water with a hot air drying part to feel “completely dried”. There was a problem in that it required disposal and the toilet user could not wait and was inconvenient to use.
As a result, the toilet user may not have a complete local cleanliness and the anus and the pubic area may be wet or moistened to remove the discomfort of getting wet after the shower shower. It is customary to wipe off the toilet with toilet paper, and hot air drying is not widely used in the world at present.
Therefore, the third problem is that the work of "wiping the buttocks with toilet paper", which is the cause of the outbreak of food poisoning even now when the toilet system has been developed due to the contamination and spread of the infectious pathogens, is not eliminated. It is.
The fourth problem is that it is difficult for a disabled person who has sequelae due to cerebral disorder to have a sequelae of hemiplegia or an elderly person who has weak abdominal muscles. Also, it is not easy to wipe the hips after defecation.
A fifth problem is that a conventional vacuum flush toilet is used for an aircraft or a Shinkansen train toilet, but the system cannot be used for home use as it is. Further, the patent document discloses an application example mainly for nursing care using a large-sized vacuum pump. However, there is a problem that a caregiver is troubled and a complicated system becomes large and expensive. As a sixth problem, it has been a long-standing problem to make the area around the toilet bowl unsanitary by splashing urine water in the standing urination process.

The solution of the present application is to devise the shape and structure of the toilet seat and the toilet so that the toilet bowl becomes a substantially airtight space when the toilet user sits on the toilet seat. The purpose of the present invention is to develop a process sequence for managing and controlling a device and a toilet device system having a waste disposal device having a gas-liquid separating means using a microcomputer, and solving the problems.

The present application has solved the above-mentioned six problems of the flush toilet having the conventional hot water washing and hot air drying device, and realized a toilet system that does not use toilet paper. By fundamentally resolving and eliminating urine in the vicinity of the toilet by urinating in the suction air flow, furthermore, assisting defecation so that disabled people with weak abdominal muscles and elderly people can defecate smoothly. After the defecation, it is possible to clean the buttocks sufficiently and completely dry it in a short time.Drainage is discharged to the sewer pipe by the flow of the washing water and exhaust air, and the toilet is made without toilet paper. The effect of greatly reducing the load can be expected.

In order to achieve the object of the present application, a method for solving the problem includes a pulse generator that sufficiently performs cleaning after defecation, and a filth having an electric motor that drives a suction unit that suctions and discharges air in a filth pool at a discharge port of a toilet. Connect a processing device and combine the functions of the in-line hot water creation device and hot air creation device to create a mechanism for defecation assist, pulsed water washing, and rapid drying, and mix the waste and toilet water excreted in the toilet bowl. The grinding rotary blade for fine grinding, the suction means, and the auxiliary rotating blades of the gas / liquid separation means are installed by penetrating the rotating shaft of one electric motor, and the electric motor is powerfully cooled by the separated clean air. The purpose of the present invention is to develop a waste disposal apparatus that discharges waste water to a sewer pipe and discharges waste liquid to a sewer pipe, and develops a toilet system that controls a toilet process sequence by a microcomputer.

FIG. 1 shows the overall configuration of the toilet-assisted suction-type flush toilet of the present application, FIG. 14 shows a control system diagram of the system, and FIG. 15 shows an overall flowchart of the toilet process.
The toilet process sequence includes a preparation process and a main process sequence.

As shown in FIGS. 5 and 6, the structure of the toilet 48 and the toilet seat 3 of the present application is provided with water-repellent resin layers 5 and 6 on at least one or both of the upper peripheral edge 7 of the toilet 48 and the opposing surface of the toilet seat 3. When the toilet user sits on the toilet seat 3, the gap is filled with the water-repellent resin layers 5 and 6.
Moreover, as shown in FIGS. 6, 6-a, 6-b, and 6-c, the shape of the toilet seat is raised in an inverted V-shape at the center line of the front portion of the toilet seat. The shape fills the space of the triangle to be created.

1 and 2 show a waste disposal apparatus 49.
A silent sirocco fan 12 for creating a suction airflow and a rotating body 13 of a waste crushing blade 14 are installed on a rotating shaft 20 of one electric motor 11, and the waste discharged from the waste storage 8 of the toilet 48 and the washing water are removed. When the electric motor 11 rotates at high speed and the sirocco fan 12 rotates, it falls into the crushing groove 16 of the waste crushing device 49 together with the suction airflow. The dirt is crushed by the rotation of the crushing blade 14 in the crushing groove 16, and the suction airflow and the filth water flow into the cyclone 18 over the outer wall 68 of the crushing groove 16 by centrifugal force. The wire does not flow into the cyclone 18 due to the wire mesh 90 provided on the outer wall 68 of the groove. When the wastewater containing the waste that has been pulverized into fine particles enters the suction airflow and the cyclone 18, the wastewater is separated into gas and liquid by centrifugal force.
At the center of the cyclone 18 is provided an air take-out pipe 22 for taking out a clean gas to the outside, and the rotation shaft 20 of the electric motor 11 passes through the center. Auxiliary wings 21 are installed on the rotating shaft 20 and rotate at the same rotation speed as the electric motor 11, so that the clean gas at the center of the cyclone device 18 is strongly sucked and air is pushed out. The clean air is guided to a hood 29 surrounding the electric motor 11 and used for cooling the electric motor 11.
The sirocco fan 12, the crushing blade 14, and the auxiliary wing 21 installed on the rotating shaft 20 of the electric motor 11 are simultaneously rotating, so that the above-described processing is performed simultaneously.

The electric motor 11 is a household power supply, an electric motor of 50 to 500 Watt is used, and has an output variable control circuit using a PWM control circuit. It is possible to adjust to the suction power desired by the user.
The microcomputer is programmed standard rotation of the electric motor 11 in accordance with the progress of the process, the suction amount speed of the electric motor 11 is "2-stage dry" process (M ³ / min) is the discharge amount of the drying hot air A low-speed rotation that does not exceed the speed is commanded by the microcomputer. However, at the "end" of the process, it is reset to normal rotation.

As shown in FIGS. 1 and 4, hot water used for local cleaning is produced by in-line hot water producing devices 39 and 32, and a heater 32 for heating supply water sent by a gear pump 30 in-line, and an in-line temperature sensor 34. And the heating control unit 39, and the temperature control was set to an appropriate temperature of 38 ° C and an appropriate temperature range ± 2 ° C.
The discharge power of the discharge hot water can be adjusted by controlling the rotation speed of the gear pump 30 from the remote 107 at hand.

The hot air used for drying is produced by an in-line hot air generating device 59, and includes a blower fan 50 for blowing in-line, an in-line hot air temperature sensor 54, a heater 53, and a heating controller 59. The temperature was controlled at an appropriate temperature of 38 ° C. and an appropriate temperature range ± 2 ° C. as in the case of the hot water. Alternatively, for hot air drying, it is also effective to design the temperature to be higher than the hot water temperature to speed up the drying. However, you must take into account dangers such as burns.

The hot water washing cylinder nozzles are provided with bidet washing 42 and 43 and buttocks washing 40 and 41, and a pulsed water flow generator 38 is provided immediately before the buttocks washing cylinder 40.
The pulse cleaning is prepared for the ass cleaning and defecation assist under the standard conditions shown in FIG.

The bidet cleaning cylinder nozzles 42 and 43 discharge a straight stream of water and are also used for bidet cleaning applications and "warm water stimulation" for defecation assist.

A method for creating a pulsed water flow with the pulse water flow generator 38 shown in FIGS. 8 to 10 is to stop the water flow flowing through the pipe by completely closing the on-off valve or to fully open the water flow by maximizing the water flow. Thus, a pulsed water flow is obtained.
FIGS. 8A and 8B show a type in which the valve plate 91 is moved up and down by an electromagnetic coil 93 with respect to a water flow to open and close.
9A and 9B are cylindrical rotating bodies in which the on-off valve 95 has a cylindrical shape and intersects the buttocks washing hot water pipe 45 at right angles. The rotating body has a cylindrical hole having the same diameter as the conduit 45, and the direction of the cylindrical hole is the conduit If it is the same as 45, it is fully open, and if the cylindrical hole is perpendicular to the conduit, it is fully closed.
When a single ON pulse is input, the cylindrical rotary valve 95 is a rotary stepping solenoid that rotates 90 degrees in one direction. When the fully open state of the water flow is electrically turned off for 2 seconds, the fully open state of the water flow for 2 seconds is turned on. Then, when the cylindrical rotary valve 95 rotates 90 degrees by the next ON pulse of the electric signal, the water flow is fully closed, and when the signal is OFF for 2 seconds, the water flow becomes a fully closed pulsed water flow for 2 seconds. By repeating this, the pulsed water flow shown in FIG. 7 can be obtained. In other forms, a similar pulsed water flow can be created using a ball valve.
In addition to the two types of pulsed water flow generators shown in FIGS. 8 and 9, a pulse waveform can be formed by the ordinary ON / OFF valve shown in FIG. 10, but the O-ring 97 on the contact surface of the valve can withstand many uses. There are no drawbacks.

The purpose of the defecation assist is to stimulate the anus by a straight water flow or a pulsed water flow to stimulate the anus and promote self-defecation, as described later. The straight water flow 123 or the pulsed water flow 124 can be remotely selected by the toilet user. Do.

In addition, pulsed water flow is a standard condition for flushing the buttocks after defecation, and a thick pulsed water flow is intermittently discharged to the wrinkles of the anus, and the anus is closed and opened to perform cleaning. Then, effective cleaning can be performed.
However, a narrow pulsed water flow may damage the anal mucosa and cause bleeding, so a thick pulsed water flow is preferable. It should be noted that the buttock is moved slightly back and forth and back and forth during cleaning, and that pulse cleaning is not continued at the same location for a long time.
A thick stream of about 10 mm diameter is used for the cleaning application of the present application.

When the consumption of hot water increases, cold water is discharged from the storage-type hot water creation device, which is uncomfortable. In order to avoid such a phenomenon, it is preferable to use an in-line type hot water producing apparatus.

The rapid drying process is performed in two stages. Most of the moisture in the wet area when the local area is washed is attached to the pubic hair and the skin in the form of water droplets. Therefore, when the “first-stage drying” is started by the “drying” command 119, the waste disposal apparatus The rotation of the electric motor 11 causes the sirocco fan 12 to rotate, thereby sucking the air in the waste pool 8 of the toilet at a high speed.
At this time, in the present application, as described above, the gap between the toilet seat 3 and the toilet bowl 48 is closed, and the suction airflow passes between the thighs of the toilet user and flows into the pubic region and the buttock in a concentrated manner. As a result, the pubic hair and skin vibrate violently, and the attached water drops are mechanically shaken off in a short time.

The second stage of “drying” is a process of drying a site wet with a large amount of warm air, and a small amount of moisture remaining on the skin surface is removed through the “first stage suction drying” process. Dry in a short time with hot air discharge. At this time, the sirocco fan 12 of the waste disposal device 49 rotates at a low speed, sucks the waste air from the waste outlet 9 of the toilet 48 with a suction airflow slightly smaller than the discharge amount of the hot air nozzle, and the warm air dries the local surface. The electric motor 11 and the sirocco fan 12 are programmed so as to rotate by suction to such an extent that does not decrease.

As a variable output control device of an electric motor, for example,
https://www.amazon.co.jp/PWM-400W-%E3%83%A2%E3%83%BC%E3%82%BF%E3%83%BC-%E3%82%B3%E3% 83% B3% E3% 83% 88% E3% 83% AD% E3% 83% BC% E3% 83% A9% E3% 83% BC-% E3% 83% A2% E3% 82% B8% E3% 83 % A5% E3% 83% BC% E3% 83% AB / dp / B00IK6P8KI
There is "PWM 10A 400W DC motor speed controller module".
As described above, a rapid drying process after cleaning was realized.

The suction force is used to stimulate the anus and rectum of the buttocks of the person sitting on the toilet seat 3, to enhance the defecation and assist the defecation, and the pulsed water flow generator 38 sufficiently cleans the anus after defecation. As a result, the process for drying the drying portion in a short time was completed.
As a result, the operation of wiping the buttocks with toilet paper is unnecessary, and a toilet flush suction type flush toilet system that solves the problems of the conventional flush toilet has been completed.

As described above, since the electric motor 11 rotates in each process, the sirocco fan 12, the crushing rotary blade 14, and the cyclone auxiliary wing 21 rotate each time, and even when dirt remains in the crushing groove 16, all the toilet processes are performed. There is a chance that the waste treatment process will be performed many times before the operation is completed, and all the waste can be discharged to the sewer 26.

Unlike the conventional flush toilet, the toilet bowl 48 according to the present application does not have a flush knob for discharging waste after the toilet, does not require a flush water tank, and does not require a siphon structure. It is a simple and compact toilet as a high-performance toilet system.

The toilet process sequence of the embodiment is shown below.
FIG. 15 shows the entire sequence of the toilet process sequence.
The first of the preparation sequences is a "hot water discharge standby" sequence shown in FIG. 16, in which the heater 32 is arranged in-line in the middle of the pipe 33 through which the supply water flows, as shown in FIGS. The PID control is independently performed by the signal of the temperature sensor 34 and the heating temperature control device 39, and the ON / OFF of the device is a system controlled by a microcomputer, which is shown in a "hot water discharge standby" sequence in FIG. In this way, the hot water that does not enter the appropriate temperature range is switched to the direction in which the second electromagnetic three-way valve 36 is released into the waste pool 8 so that only the hot water that enters the appropriate temperature range is discharged to the washing unit, and is then discharged. If a command to start the process of using hot water is not issued even if the temperature enters the appropriate temperature range, the hot water is discharged to the waste pool 8, T Low is set to 36 ° C., T High is set to 40 ° C., and the temperature is set. Is suitable around 38 ° C Only the warm water of the width so as to discharge towards the human body. However, the discharge hot water flow rate during the standby period is about 1/2 of the prescribed discharge hot water flow rate, and when there is a discharge command, the supply water of 100% of the design flow rate increases the rotation of the gear pump 30 to in-line hot water heating. The water is sent to the heater 32, and hot water is discharged to the cleaning part at a design rate.
Therefore, it is possible to discharge hot water at an appropriate temperature range and at a specified rate from the beginning of the discharge toward the cleaning site. For example, as an in-line hot water generator 39
There is http://www.nippon-heater.co.jp/products/liquid/sgl/.

The second of the preparation sequence is a "warm air discharge standby" sequence, in which an in-line warm air generator 51 having its own blower fan 50 as shown in FIG. 1 and FIG. An independent temperature control circuit 59 is provided to generate hot air having a set temperature range by the heating heater device 53, and ON / OFF of the device is controlled by a microcomputer. The appropriate temperature range of the hot air is also set to the same temperature as the hot water, and the hot air that is not within the set temperature range and the hot air during the period in which the dry hot air command is not received are passed through the sewage pipe 58 by the third three-way solenoid valve 55 through the sewage pipe 26. Has been released. However, it is on standby with the discharge hot air flow rate being about 1/2 of the design flow rate, and is switched to 100% of the design flow rate after receiving the dry hot air command to reduce the wasteful energy. I have less.
Therefore, it is possible to discharge at a design rate at an appropriate temperature width from the beginning of the hot air discharge.
For example, as in-line warm air generators 51, 53, 59

The first, second, and third electromagnetic three-way valves 35, 36, and 55 used in the apparatus structural diagram of the present invention shown in FIG. product / general-ball / T3.html T3 type AE1-120 and the like.
The solenoid valve 63 is a two-way solenoid valve for general use.

In the toilet process of the present invention, the standard conditions are programmed in the microcomputer, and the process conditions can be changed remotely. When the sequence end is instructed by the process “end” command, the sequence is reset to the standard conditions again. I have.

The first of the main process sequence of the present application is a “standing urination process” shown in FIG. Otherwise, the microcomputer determines that it is a “standing urinal process”.
Then, during execution of the “standing urination process”, even if a sequence start command of another process is erroneously pressed, the sequence is locked without being “started”. The sequence to be locked is “butt cleaning”, “bidet cleaning”, “defecation assist”, and “drying sequence”.
However, when the “standing urination process” is “finished”, the sequence lock is released.

It goes without saying that the "standing urination process" sequence is not initiated when the seating sensor senses.
When the “piss in the standing position” action is performed and the “piss discharge” command switch 113 is pressed, the electric motor 11 is driven and the sirocco fan 12 is rotated. The electromagnetic valve 63 opens along the wall of the waste pool 8 for about 10 seconds, flushing water flows from the upper edge 7 of the toilet bowl, and the waste water falls to the crushing groove 16 of the waste disposal apparatus 49.
Due to the strong suction airflow and the rotational centrifugal force of the crushing blade 14, the liquid level of the waste liquid becomes higher than the outer wall 68 of the crushing groove 16 and flows into the cyclone introduction passage 17 over the outer wall 68. The waste liquid flows from the tangential direction of the cyclone 18, the air and the liquid component are separated by the centrifugal force of the high-speed vortex of the cyclone 18, the liquid component is pushed to the wall of the cyclone 18, and the waste water discharge pipe below the cyclone 18. It flows down to 23 and is discharged to a sewer pipe 26 through a sewer pipe 25. The air component is taken out from an air take-out pipe 22 provided at the center of the cyclone. A waste prevention cover 19 is attached to the upper part of the air extraction pipe 22 so that waste water does not enter.
The rotation shaft 20 of the electric motor 11 penetrates through the center of the air extraction pipe 22, and the auxiliary wing 21 is installed on the rotation shaft 20. The auxiliary wings 21 installed on the rotating shaft 20 of the electric motor 11 are rotating in the same manner as the electric motor 11, and strongly suck / push out the clean air in the center of the cyclone which is not mixed with the liquid component. The electric motor 11 is conveyed to the hood 29 of the motor 11, cools the electric motor 11, and is then discharged to the drain 26 through the air discharge pipe 27.

The "piss discharge" command switch 113 is automatically turned off after 10 seconds, the sequence lock is released at the same time, and the "piss discharge" sequence is automatically "terminated".
When the toilet user exits, the human sensor detects the exit and the “post-washing” sequence shown in FIG. 24 is automatically performed, and the fourth solenoid valve 63 is turned on from above the waste pool 8 of the toilet 48. When opened, about 3 L of washing water flows to wash the waste residue on the toilet surface and the waste pool 8 surface, and also serves to stop the odor from the waste disposal device 49 by storing the wash water in the toilet odor stopper 69. I do. The fourth solenoid valve 63 is automatically turned off after 5 seconds.
This completes the “standing urination process”.

The second of the main process is the process sequence of “bide cleaning” shown in FIG. 19, and the preparation process of “hot water discharge standby” shown in FIG. 16 is performed as shown in FIG. If the "discharge standby" sequence is activated and a "hot water discharge" command is issued, the appropriate temperature of hot water can be discharged from the nozzle at any time.
When there is a command 114 to start “bidet cleaning”, the second three-way valve 36 is switched to a bidet nozzle pipe, and hot water of an appropriate temperature width is supplied to the bidet cylinder nozzles 42 and 43, and a straight water flow is discharged from the bidet nozzle 43. You.
The bidet washing can change the water force of the standard condition with the remote 117, 118 with the hot water flow of the straight water flow, and it is memorized when the water pressure condition is changed. When the "bidet cleaning" command is pressed again, the microcomputer determines that "the bidet cleaning is to be re-cleaned" by the same toilet occupant, calls the memory condition, and performs the cleaning under the same conditions as the previous cleaning conditions. The system is easy to use for the user. When the bidet cleaning process is completed, the process proceeds to a “first-stage suction drying” and a “second-stage hot-air drying” processes described later.

When the bidet cleaning and drying are completed, and the toilet user leaves the toilet seat, the seating sensor "detects leaving", the memory of the cleaning condition disappears, and the standard condition is reset.

The third sequence is “defecation assist” shown in FIG. 20, in which an elderly person with weak abdominal muscles or a disabled person gives warm water stimulation and suction stimulation to the buttocks to elevate defecation and perform self-defecation. It is a sequence that helps.
“Straight hot water flow stimulation” 123 and “pulse hot water flow stimulation” 124 are selected from the “defecation assist” command board 115, and the command switches of “stop hot water discharge” 125 and “suction stimulation” 126 are remote. It is prepared in. If the “defecation assist” command board 115 shown in FIG. 13 is installed independently of other command boards, it is easy for a toilet user to understand.

That is, in the case of defecation while sitting on the toilet seat 3 and the toilet bowl 48 having the structure proposed in the present application, first, a person who can defecate by himself performs defecation by himself, but a person with low constipation “straight warm water flow stimulation” 123 toward the anus. Is issued, the hot water of the straight water flow is discharged from the bidet hot water discharge nozzle 43 toward the anus under the standard condition. The toilet servant adjusts the position of the buttocks so that hot water is applied.

If the user desires to stimulate the anus with pulsed hot water stimulation and enhance the defecation of the bowel, selecting the "pulse hot water flow stimulation" command 124 switches the three-way solenoid valve 35 to supply hot water to the ass washing pipe. Then, the pulse water flow generator 38 is operated, and the same “pulse hot water flow stimulation” mode as the post-defecation pulse hot water flow shown in FIG. 7 composed of the straight water flow and the pulse water flow under the standard conditions is discharged from the nozzle.
In the case where defecation can be performed on its own due to the excitement raised by the warm water stimulation, the discharge of hot water is stopped by the “stop discharge of hot water” command 125 to “defecate”.

In addition, when the defecation convenience is low, when the "suction stimulation" command switch 126 is pressed, the electric motor 11 is driven, and the sirocco fan 12 rotates for about 10 seconds to discharge the air from the waste pool 8 of the toilet 48.
As shown in FIGS. 6 and 6-a to 6-c, the shape of the toilet seat of the present application has a structure 67 that rises on the center line of the front part of the toilet seat,
When sitting on the toilet seat, placing the thighs in the shallow U-shaped groove 66, and contacting both kneecaps with each other and closing the knee, a substantially triangular space on the center line formed by the thighs and the toilet seat The toilet seat 3 and the water-repellent resin layers 5 and 6 at the upper part of the toilet contact with each other as shown in FIGS. 1 and 5, and FIGS. Since the gap is closed, the waste pool 8 of the toilet 48 is substantially airtight.

When the "suction stimulation" switch 126 is turned on while sitting on the toilet 48 and the toilet seat 3 of the present application, the sirocco fan 12 of the waste disposal device 49 rotates at a high speed, and when the air in the waste pool 8 is sucked, the toilet user I feel the stimulation that my buttocks are strongly sucked. A similar "suction stimulus" is felt in the anus and rectum when the suction tube of a home vacuum cleaner is closed by hand. When the suction force is too large, the output of the electric motor 11 can be remotely adjusted by the suction force adjustment dial 127.
The electric motor 11 automatically turns off in about 10 seconds.

When stool or gas coming down near the anus of the rectum tries to come out of the anus, the feeling becomes exhilarating and “defecation” is performed.
Unless the suction stimulus is given by the defecation assist, it goes without saying that the posture of sitting on the toilet seat is as usual, with both kneecaps widened to shoulder width and relaxed.

However, even for those who are still unsatisfactory, the sequence is such that they can repeatedly stimulate the rectum and anus by repeating "warm water stimulation" and "suction stimulation". It is effective for those who have difficulty in defecation because they can defecate smoothly.

However, instead of the defecation assist that sucks the stool out of the rectum with a negative pressure, the “defecation assist” of the present application is to perform the defecation by itself and to enhance the defecation to encourage defecation.

When the defecation is completed, the process proceeds to the “butt washing” process shown in FIG.
The fourth sequence is a process of “tail washing” shown in FIG. 21. When a command 116 of “tail washing” is issued, the first electromagnetic three-way valve 35 is cut in a direction in which water flows through the tail washing cylinder 40. Instead, the hot water generated by the in-line hot water generators 32 and 39 forms the pulse water flow shown in FIG. 7 by the pulse water flow generator 38 shown in FIGS. 8A to 10B, and the nozzle 40 under the standard pulse water flow conditions. , 41, a thick warm water stream having a diameter of about 10 mm is discharged toward the anus. The thickness of the hot water flow is determined by the design of the nozzle port 41.
The flow pattern of the standard pulsed water flow shown in FIG. 7 is a pattern 100 in which a pulsed hot water flow in which a straight water flow 99 flows for about 5 seconds, then pauses for 2 seconds, and flows for 2 seconds is repeated 5 times, It is possible to wash off the dirt that has arrived at the details of the anal wrinkle with a shock wave that turns it on and off, and to change the water condition from the standard condition to “strong” or “weak”. The re-cleaning is a sequence in which the memory is called up and the cleaning is performed under the previous condition.
The ON / OFF condition for determining the pulse width of the pulsed water flow generator 38 is operated by inputting a pattern in advance to the microcomputer.
Since the in-line hot water generators 32 and 39 are used, it is possible to repeatedly discharge and clean the hot water for as long as necessary, and to sufficiently clean the tail.

FIGS. 8A to 10B show the fully opened and completely closed water states of the three types of pulsed water flow generators 38, respectively. In the embodiment, FIGS. 8A and 8B show the state. A pulsed water flow generator was used. Although the pulsed water flow shown in FIG. 7 can be generated by three types of pulse generators 38, the pulse generators 38 of FIGS. 8 and 9 have a structure that is resistant to wear and can withstand long use.

The fifth sequence is a "first stage suction drying" process sequence shown in FIG.
When the sirocco fan 12 rotates by the rotation of the electric motor 11 and sucks the air in the filth pool 8, the suction airflow passes between the thighs of the person sitting on the toilet seat 3 and concentrates violently on the pubic region and the buttocks. Passing while shaking pubic hair and skin. At that time, water drops adhering to the pubic hair and skin are mechanically shaken off. Most of the moisture that is wet due to the washing process and the butt warm water stimulation is present in the buttocks and the pubic area in the form of water droplets, so that most of the moisture has been removed by the suction airflow.

The “first-stage suction drying process” in FIG. 22 is “started” when the “dry” command 119 is pressed, and the “hot-air discharge” in FIG. 17 is prepared in preparation for “second-stage hot-air drying” in FIG. A "standby" process is started.
Then, the waste discharged into the waste pool 8 of the toilet 48 is sucked into the waste disposal device 49 together with the washing water.
When the sirocco fan 12 rotates, the filth, sewage and washing water are sucked by the suction airflow and fall into the crushing groove 16, and the crushing rotating body 13 having the plurality of crushing blades 14 installed on the rotating shaft 20 of the electric motor 11 operates at high speed. Because it is rotating, the filth is finely crushed and becomes as fine as crushed by a mixer.
The crushing groove 16 has a depth, and feces are crushed in the crushing groove 16 for a while. When the liquid level of the wastewater rises above the height of the outer wall 68 of the crushing groove 16, the wastewater enters the cyclone device 18 through the cyclone introduction path 17 together with the suction airflow.
Since the crushing groove 16 and the cyclone introduction path 17 are attached so that the suction airflow enters from the tangential direction of the cylindrical cyclone 18, the fine dirt and the suction airflow vortex at high speed in the cyclone 18.
In the cyclone 18, the fine dirt and the liquid component are pushed by the wall of the cyclone 18 by the swirling airflow, gather downward along the wall of the cyclone 18, flow into the waste water discharge pipe 23 provided at the lower part of the cyclone, The water is discharged to the sewer pipe 26 through the sewer pipe 25.

On the other hand, the clean air component from which the fine contaminants have been removed is taken out of the cyclone 18 from the center of the cyclone 18 by the air take-out pipe 22. The rotation shaft 20 of the electric motor 11 attached to the upper part of the waste disposal device 49 penetrates through the center of the air extraction pipe 22, and the auxiliary wing 21 attached to the rotation shaft 20 rotates at high speed to provide powerful air. The clean air cools the electric motor 11 because the clean air pipe 24 is connected to the electric motor hood 29 surrounding the electric motor 11 by generating a suction force and an air pushing force. Thereafter, the air is discharged to the sewer pipe 26 through the air discharge pipe 27.

The sixth sequence is the “second-stage hot air drying” shown in FIG. 23, and the electric motor 11 is automatically turned off after 10 seconds in the first-stage suction drying process, and then automatically again. The rotation is started.
In the “second-stage hot air drying”, the output of the electric motor 11 is reduced, and the sirocco fan 12 sucks a small amount of suction speed from the waste pool 8 at a low rotation speed.
This is a measure to prevent the drying effect of the hot air drying from being lost and to prevent the bad smell from reaching the toilet user's face.
This is because if the output of the electric motor 11 is large and the suction force of the sirocco fan 12 is large, the effect of hot air drying is reduced. This is because the stench of the filth pool comes up.
The microcomputer is programmed so that the output of the electric motor 11 is suppressed to a low output and the sirocco fan 12 rotates at a low speed.
The hot air discharge amount speed and the suction amount speed are determined at the design stage.

This delicate balance is set up by installing a pressure sensor that detects the differential pressure between the waste pool side and the atmosphere side, and using the hot air discharge rate from the nozzle so that the waste pool is slightly positive with respect to the atmospheric pressure. A method of controlling the rotation with a microcomputer so as to slightly reduce the speed of suction by the sirocco fan is also conceivable.

In the first-stage and second-stage drying sequences shown in FIG. 22 and FIG. 23, the hot-air discharge standby is started when the in-line hot air generators 51, 53, and 59 instruct “dry” 119. Therefore, it is in a state where the warm air can be discharged immediately for the second stage drying.
When the electric motor 11 starts rotating at a low speed designed by the microcomputer, a large amount of hot air is discharged from the hot air nozzle 57 at the same time.
The rotation of the electric motor 11 is programmed in the microcomputer so as to suck the air flow rate slightly lower than the discharge rate of the hot air from the waste disposal apparatus 49. The moisture remaining in the water is rapidly dried.
The user can continue until the toilet user feels “dry” in the second drying, and presses “END” 120 to end the “second drying” process.
The power of the electric motor and the power of the in-line warm air device are turned off.

The toilet user prepares himself, leaves the toilet room, and starts the “post-washing” sequence shown in FIG. 24 when the motion sensor or the toilet seat sitting sensor detects the absence.

As described above, the “post-washing” is to turn on the fourth solenoid valve 63 to serve to wash the dirt and the like adhering to the surface of the dirt pool 8 of the toilet 48, and After installation, about 3 L of washing water flows from the washing outlet 62 and flows along the inner surface of the waste pool 8 to wash the inside of the toilet, and the washing water collects in the odor stopper 69 and the crush groove 16 of the toilet, It plays a role of stopping the odor from the waste disposal device 49.
As described above, the entire sequence of the toilet process is completed.

As shown in FIG. 14, the toilet system of the present invention is process-managed intensively in a microcomputer control circuit, and a sequence is programmed.
Process start and end commands from the hot water and hot air temperature sensor signals, motion sensor and seat sensor signal, remote switches 113, 114, 116, 119, 120 and hot water flow stimulation modes 123, 124, 125, A command signal for changing 117 and 118 of the cleaning water force is input to the microcomputer in the middle of the sequence, and a change of the high / low speed rotation control 126 and 127 of the sirocco fan 12 is programmed. Further, when the "end" command is pressed, the process in which the condition is changed is reset to the standard condition. The standard condition is also programmed in the microcomputer.
The power supply of the electric motor 11 of the waste disposal apparatus 49, the electromagnetic valve 63 including the electromagnetic three-way valves 35, 36, and 5, the power supply of the piping system, the hot water and hot air in-line heating system power supplies 39 and 59, and the apparatus power supply of the pulse water flow generator 38 Are ON / OFF controlled from the microcomputer control circuit to the power supply of all devices via the relay block according to the process sequence.
Although the temperature control of the in-line hot water device 39 and the in-line hot air device 59 has a local independent control circuit, it operates according to a sequence controlled by the microcomputer control circuit.

If the temperature of hot water and hot air exceeds 45 ° C., it is determined that an abnormality has occurred, and in an emergency state in the event of an abnormality, an emergency stop for stopping power supply from the microcomputer control circuit is given priority. Have.

The technical contents using the improved waste disposal apparatus as a second embodiment of the present invention will be described below.
Note that paragraphs (0011) to (0057) are descriptions of the specification of the earlier application (Japanese Patent Application No. 2018-127425), and the other paragraphs describe the technical contents of the second embodiment according to the present application. Things.

In the prior application, the water system used in the buttocks cleaning process is shown in FIGS. 1 and 4, a water system diagram, and FIG.
In the second embodiment of the present application, the water system using the pressure reducing valve 215 and the accumulator 214 is clearly shown in the water system diagram of the toilet system in FIGS. 25 and 35.
FIG. 40 shows the details of the pulse water flow discharge water pressure waveform in FIG.
In the prior application, although not described, a pressure reducing valve is used for the main line of the washing water system, the water pressure of the entire nozzle water system is adjusted to a low water pressure, and the accumulator 214 is provided with a bidet pipe and a bottom cleaning pipe. It is installed at a close position upstream of the open / close solenoid valve.

In the earlier application, since the accumulator was not considered to directly affect the toilet function in FIG. 1 and FIG. 4, the accumulator for water hammer countermeasures uses a pulsed water flow generator 38 for rapidly closing and opening the waterway in the water system. Is considered to be understood to be used without being described, and the pressure reducing valve and the accumulator are omitted, and the simplified substantially rectangular wave is shown in FIG. 7 without any explanation. Is discharged to the anus, and the pressure reducing valve 215 and the accumulator 214 are actually used.
In the earlier application and the second embodiment of the present application, the pulsed water flow generator 38 and the accumulator 214 for countermeasures against water hammer have a reduced impact force generated by interference with the water hammer countermeasure, and high cleaning ability remains. Pulsed hot water containing shock waves is used for ass cleaning.

In paragraph 0040 of the previous application, even in the defecation assist process, when a command of “pulse hot water flow stimulation” is issued once remotely, the same hot water flow as in the ass washing shown in FIG. 7 is discharged. It is described.
Also, in paragraph 0046, “The water flow pattern of the standard pulse water flow shown in FIG. It is a pattern 100 that is repeated and is washed with a shock wave that turns on and off dirt that has reached the details of the anal wrinkle.
FIG. 40, which is described in detail below, represents that a pulse stream including a shock wave with a reduced impact force included in a rising period of the pulse water flow at the time of ON is washed under standard conditions.

Again, the earlier application and the second embodiment of the present application, the defecation assist and the pulse water flow generator 38 used in the buttocks cleaning process, and to prevent the water hammer phenomenon occurring at the time of ON / OFF The function of the accumulator 214 and the discharge water of the present application having a substantially rectangular wave discharge force discharged toward the buttocks cleaning section will be described below for better understanding.

Generally, rapid opening and closing operations are performed in water flow pipes for flowing city water with high water pressure, such as household baths, washing machines, water heaters, toilet facilities, industrial air conditioners, and plant facilities. In applications where a valve body that performs water hammering is installed, a water hammer phenomenon occurs unless water hammer countermeasures are taken, and in the worst case, a shock wave enough to destroy water-based equipment shown in FIG. 36 is generally generated. Is known.

Regarding the function of the accumulator 214, for example, a structure in which nitrogen gas from NOK is sealed in a bladder made of thick rubber is widely used. http://www.nok.co.jp/product/fluid.html

Please refer to.
In the piping flow path that constitutes the solenoid valve that opens and closes rapidly in the water system, close to the solenoid valve device that turns the water channel ON / OFF in order to prevent the water system device from being destroyed by the water hammer phenomenon Therefore, it is common sense to install a water hammer prevention device such as an accumulator on the upstream side.

The effect of the accumulator 214 and the shock wave generated by ON / OFF of the pulse water flow generator 38 will be described below.

The water system of the second embodiment of the previous application and the present application is a water system that uses a low water pressure by adjusting the water pressure with a pressure reducing valve 215 to wash a sensitive part of a human body. However, since the rapid opening and closing are performed using the pulsed water flow generator 38, the water system is likely to generate a strong shock wave even at a low water pressure and damage a local part of a human body.
First, in the low-pressure water system of the second embodiment of the prior application and the present application, as a simple model for illustrating the shock wave of the water system in which the water hammer prevention device such as the accumulator 214 is used, FIG. Consider a model water system like 37.
In the prior application and the present application, the pressure of the water supply pump 240 in the low water pressure system is set to P, a point A on the downstream side immediately after the solenoid valve 242 for performing rapid opening and closing, and an upstream side immediately before the solenoid valve 242. It is possible to use a water-based model in which the point B, the most downstream side of the pipe 241 is an open end (nozzle open) a 243.

When the water flow flowing in the pipe 241 is rapidly opened or closed by the solenoid valve 242 and the speed of the water flow is suddenly changed, a compression wave is generated in the water flow, and an abnormally high water pressure is generated in the pipe 241. May occur.
Since the velocity at which the compression wave propagates through the pipe is as high as 1200 m / sec, the first wave shock wave with the highest energy of the water hammer phenomenon is generated before and after the solenoid valve 242 in a short time within about 0.2 seconds. It is known.

In the model water system of FIG. 37, when the solenoid valve 242 is turned on, the valve is rapidly opened, and the water flow is caused to flow in the direction of the downstream nozzle, the water pressure change at the point A suddenly opens to a large amount as shown in FIG. When the water stream begins to flow, the density of water at the tip of the water stream increases, forming a positive pressure shock wave with high water pressure and high energy.
The water flow is continuously flowing through the pipe 241, and the shock wave of positive pressure or negative pressure (honey or coarse) is instantaneously propagated. It is thought that it is transmitted to the whole water system from when ON / OFF.
Accordingly, the shock wave of positive pressure generated at point A by rapidly opening the valve at the time of ON is suppressed in a direction in which the shock pressure becomes coarse due to the interference phenomenon of the accumulator 214, and the shock force represented by a in FIG. It becomes a suppressed shock wave and is discharged as a water flow from the discharge nozzle.

At this time, on the point B side upstream of the solenoid valve 242, the water flow is pulled to the point A side, so that water is separated from the water and a shock wave in a negative pressure direction in which the density is low (coarse) is generated. After passing through the accumulator 214, the energy of the opposite positive pressure is applied, resulting in a shock wave with reduced impact, which propagates upstream. However, the shock wave propagated upstream is not discharged from the downstream nozzle.
The above-mentioned phenomenon in which the impact force is reduced at the points A and B occurs almost simultaneously because the water flow is connected, and when the shock wave passes through the accumulator 214, the impact wave is suppressed at each point. .
On the other hand, when the solenoid valve 242 is turned off and rapidly closed in a state where the water flow is flowing in the pipe 241, as shown in FIG. 39B, in the water system of the second embodiment of the prior application and the present application, Since the discharge nozzle 243 has an open end, when the solenoid valve 242 is closed, there is no water flow supplied downstream from the solenoid valve 242, so that the water flow is supplied to the nozzle 243 as shown in FIG. Not done. Therefore, no water flow is discharged to the local area, and there is no impact.

However, at point B in the pipe 241 on the upstream side of the solenoid valve 242, when the solenoid valve 242 is suddenly closed and turned off, the flowing water flow is pushed to the valve by the inertia of the water and the density is increased to about twice as high. As shown by b, even when the accumulator 214 is used, a reflected wave having a considerably strong positive pressure is generated. However, the high-density reflected wave becomes a shock wave toward the accumulator 214 upstream in the water pipe, and energy is absorbed by the accumulator 214 with time, and the shock wave ends.

When the accumulator 214 receives a steep pressure change from the outside, the rubber bladder ball in which the gas is filled reacts so as to oppose an external force, so that it absorbs energy and has a high positive pressure (Honeyami). And acts as a buffer that moderates the transient phenomena in which the pressure changes abruptly by interfering to raise a high negative pressure (coarse wave).

Therefore, in the earlier application and the second embodiment of the present application, the shock wave that impacts the human body is discharged from the nozzle 41 when the pulse of the pulse water flow generator 38 is turned on and the water flow starts to flow, and is generated when the pulse rises. As shown in FIG. 38A, pulsed washing water is discharged toward the human body, including a shock wave whose impact force is suppressed by the accumulator 214 at the time of rising.
Regarding the impact of the discharged water on the local part of the human body, the first wave of the shock wave is felt most strongly.
As described above, in the case of the ass washing discharge power that the toilet user feels uncomfortable, it is possible to remotely adjust the output of the gear pump 30, and also by reducing the water pressure and the flow velocity of the feed water gear pump 30. In addition, the strength of the maximum pressure of the shock wave can be reduced, which is effective for reducing the impact feeling.

FIG. 40 shows, in an enlarged manner, the pressure change of the discharge water discharged in the buttocks cleaning process. Discharge having an impact water pressure waveform in which the impact force is suppressed at the rise of each pulse of the pulse water flow generator 38 when the pulse is ON. Water will be discharged from the nozzle.
There is a pulse flow with the rising of the water flow at the ON time of 6 times by one "butt cleaning" command. It will be washed.
Even if the shock wave is reduced in impact force, since the water pressure is higher than the water pressure P of the feed water gear pump 30, the washing power is still high, and it can be used as a discharge washing water flow for washing even the wrinkles in the anus.

However, in the earlier application and the second embodiment of the present application, it is needless to say that not only the shock wave component but also the water stream to be cleaned is cleaned during the pulse ON period.
In FIG. 7 of the earlier application, the discharge water pressure intensity of the “tail washing” shown in FIG. 40 described above is simply represented as a substantially rectangular waveform.
FIG. 35 shows a detailed view of the water system used in the previous application and the second embodiment of the present application, in which the pressure reducing valve 215 and the accumulator 214 are installed.

Next, the waste disposal apparatus according to the earlier application has the following industrial problem, and it is understood that the waste disposal apparatus of the second embodiment has been solved by making improvements in the second embodiment of the present application. explain.
That is, the waste disposal apparatus of the earlier application had the following industrial problems.
As shown in FIGS. 1 to 3, since the crushing blade 14 is attached to the rotating shaft 20 of the electric motor 11 at the tip of the long crushing rotating body 13, since the rotational moment is large, the filth and the crushing blade 14 collide. In this case, the amount of work required for the electric motor 11 when pulverizing waste is increased. Therefore, the load applied to the electric motor 11 is large, and it is necessary to use a large motor.
In order to secure clean air for cooling the large-sized electric motor 11, auxiliary air wings 21 for separating air / liquid by a cyclone device 18 to produce clean air for forced air cooling and sending it to the electric motor 11 are required. It is necessary to further increase the rotational load of the refuse and to install the cyclone device 18 in the waste disposal device 49, and the toilet system device becomes large and expensive.

In order to solve the above-mentioned industrial problems, the following contrivances have been made in the waste disposal apparatus according to the second embodiment of the present application.
First, in order to reduce the load applied to the electric motor 11, the waste is previously formed into a small lump by the coarse crushing plate 205, and the rotating shaft 20 of the electric motor 11 is not used without using the long crushing rotating body 13. The crushing blade 14 is directly attached to the crusher, and the crushing blade 14 is formed into a shape having a small turning radius to reduce the rotational moment and work during crushing. Second, a simple structure without using a large cyclone device 18 The gas / liquid separation was carried out to obtain a small waste disposal device.
Thirdly, the propeller fan 203 having a strong suction force can be used, and in another embodiment, a small-sized waste disposal apparatus using a sirocco fan 12 which is silent and has a high space utilization rate is improved.
Fourth, the electromagnetic discharge valve 211 is used as a part of the wall of the waste crushing tank 208, and the electromagnetic discharge valve 211 is closed at the time of depressurization to ensure the negative pressure in the decompression chamber 202.
Fifth, in the standing urination process, a urination process was developed to prevent urine water from splashing around the toilet bowl and dispersing and scattering some of the urine water. Prevented hygiene.

Hereinafter, the waste disposal apparatus 49 of the second embodiment and other embodiments of the present application will be described in detail.
The configuration of the waste disposal apparatus 49 according to the second embodiment includes a decompression chamber 202 and a waste discharge chamber 210, as shown in FIGS.
The decompression chamber 202 has a filth introduction unit 204 for introducing filth from the toilet 48 into the filth treatment device 49, and a gas / liquid separation unit 206 at the lower end of the filth introduction unit 204. A suction means for the propeller fan 203 or the sirocco fan 12 is attached to the shaft 20, and a waste crushing blade 14 is attached to the tip of the rotating shaft 20. Then, it is structured to grind the filth.
In the second embodiment and the other embodiments, the decompression chamber 202 and the waste discharge chamber 210 are connected by a partition 201, and the discharge airflow that has cooled the streak radiating fins 216 is provided above the partition 201. Has an opening 218 that flows into the container, has a waste water discharge port 212 at the lower part of the partition wall 201, and is provided with an electromagnetic discharge valve 211 connected to the waste water discharge port 212. When the electromagnetic discharge valve 211 is opened, The structure is such that waste water flows out of the waste crushing tank 208 below the decompression chamber 202 through the waste discharge chamber 210 to the sewer pipe 26 along the inclined path, and is transferred to the sewer pipe 26.

The first problem to be solved in the second embodiment of the present application is to reduce the grinding load.
As shown in FIGS. 25 and 26 using a propeller fan and FIG. 27 using a sirocco fan as another example, when excreted feces are introduced into the waste disposal device 49 from the waste introduction part 204 and dropped. Then, the dirt is made to collide with the coarse crushing plate 205 to form a small filth lump, and then the rotary crushing blade 14 is rotated in the crushing tank 208 to become filth water in which fine filth particles, washing water and air are mixed. As described above, the coarse grinding is performed in advance so that a large load during the grinding is not applied to the electric motor 11.

A short-length crushing blade 14 shown in FIGS. 25 to 29 is attached to the tip of the rotating shaft 20 of the electric motor 11 and rotates in the trash crushing tank 208 to collide with the small refuse lump described above. Crushed to reduce the rotational moment.
The odor control structure 69 at the lower part of the toilet bowl stores only a certain amount of water, but when more water flows from the toilet bowl, it flows into the waste crushing tank 208 of the waste disposal apparatus 49 and is collected. When the lump flows into the grinding tank 208, a lot of water is already present in the waste grinding tank 208.

Next, the waste introduction part 204 and the coarse crush plate 205 of the waste disposal apparatus 49 will be described.
The waste introduction part 204 of the decompression chamber 202 is airtightly connected to the waste discharge port 9 below the waste storage 8 of the toilet, and is stored together with the washing water in the odor prevention structure 69 below the waste storage 8 of the toilet. The dirt is decompressed by the rotation of the suction means in the decompression chamber 202 to a pressure difference exceeding the water layer thickness of the odor control structure 69, and when the pressure becomes negative, the water layer of the odor control structure 69 is broken and the atmospheric pressure of the outside air Then, the waste falls along with the washing water and the air into the waste introduction section 204 of the waste disposal apparatus 49 by a suction airflow.
As shown in FIGS. 25 to 27, a plurality of coarse crushing plates 205 are provided inside the waste introduction part 204, and the large lump of sewage after defecation falls downward together with the washing water and collides with the coarse crushing plate 205. Then it breaks down into a little litter. The waste mass and the washing water hit the sliding plate 207 which is inclined downward at the lowermost part of the waste introducing portion 204, slide down on the surface of the sliding plate 207, and fall into the waste crushing tank 208.

A description will be given of a second problem to be solved by the second embodiment, which is a structure capable of achieving a gas / liquid separation action with a simple structure.
As shown in FIGS. 25 to 27, the suction airflow is sucked through the waste introduction part 204 of the waste disposal apparatus 49. Since the air is sucked by the rotation of the suction means provided in the upper part of the decompression chamber 202, the suction airflow is turned into a U-shape at the lower end of the waste introduction part 204 and is sucked up.
When the direction of the suction airflow is sharply bent at the tip of the waste introduction part 204, the waste component and the washing water component mixed in the suction airflow are shaken off by centrifugal force, and the same as when the cyclone device 18 is used. A gas / liquid separation phenomenon occurs in which air separates from lumps and washing water.
Therefore, the suctioned airflow that has been subjected to the gas / liquid separation is a clean airflow that is free of dirt components.
Since the gas / liquid separation is performed after finely crushing the filth in the filth crushing groove 16 of the previous application, it was difficult to separate fine solids without using a full-scale cyclone device 18. In this embodiment and the other embodiments, before the filth is finely crushed, gas / liquid separation is performed at the stage where the filth is coarsely crushed into small-sized filth lump in advance. The gas / liquid separation unit 206 having a simple structure that can be changed only at the tip of the unit 204 can efficiently remove waste lump components and liquid components from the suction airflow and can be installed in the cyclone device 18 as in the embodiment of the earlier application. There is no need for the air extraction pipe 22 and the auxiliary wing 21 that have been used. The air flow can be a clean air flow used for cooling the electric motor 11.
The air that is bent by the gas / liquid separation unit 206 of the waste introduction unit 204 and strongly sucked by the suction unit becomes a rising air current, collides with the rotors (203 and 219) of the suction unit, and generates air molecules at the angle of the rotor. Is subjected to a force that is strongly pushed out, and becomes an exhaust airflow.
As described above, the dirt component and the liquid component can be efficiently removed from the suction airflow by the gas / liquid separation unit 206 having a simple structure without using the large and expensive cyclone device 18, and the clean air flow can be taken out. Therefore, the waste disposal equipment could be made smaller.

The third problem to be solved by the present application is to devise a structure that can use either the sirocco fan 12 or the propeller fan 203 as the suction means.

That is, an example in which the propeller fan 203 is used will be described below.
The propeller fan 203 is an inexpensive suction means that strongly pushes out a straight airflow in the direction of the rotating shaft 20 and has strong exhaust power.
For this reason, the propeller fan 203 is not optimal for applications in which the airflow is bent at a right angle, and the sirocco fan 12 that can easily bend the exhaust direction is generally used. However, it is expensive.
In the waste disposal apparatus 49 of the second embodiment, as shown in FIG. 25, FIG. 26, FIG. 28, and FIG. 29, the streak radiating fins 216 are provided at positions where the propeller fan 203 receives the straight exhaust airflow at right angles. Thus, the airflow was bent at a right angle to flow toward the waste discharge chamber. As a result, the propeller fan 203 having the straight exhaust air can be used.
In the examples shown in FIGS. 26, 28 and 29, the propeller fan 203 is attached to the rotating shaft 20 of the electric motor 11, and the exhaust airflow strongly pushed by the rotation of the propeller fan 203 is supplied to the upper part of the decompression chamber 202 by the electric motor. The motor 11 collides with the radiating fins 216 on which the motor 11 is installed, and performs heat exchange on the surface of the radiating fins 216 to cool the heated electric motor 11.
The shape of the streak-shaped heat radiation fins 216 is such that a plurality of lines of fins arranged in a streak shape having a large surface area are formed in order to efficiently exchange heat on the surface.
The exhaust airflow generated by the rotation of the suction means is received by the streak radiating fins 216, and the streak-like fins are installed so that the exhaust airflow can pass through the opening 218 of the waste discharge chamber 210. It flows according to the streaks of the radiating fins 216 and enters the waste discharge chamber 210 through the opening 218 provided at the upper part of the partition 201.

Another embodiment shown in FIGS. 27, 30-a to 30-c, and 31-a to 31-c is an assembly diagram of an example using the sirocco fan 12, and the semi-cylindrical rotor 219 of the sirocco fan 12 is shown. The electric motor 11 having the radiation fins 222 attached thereto in close contact with the support 225 is installed in a space inside the sirocco fan 12, and heat is exchanged by the radiation fins 222 in the suction airflow of the sirocco fan 12. Since the motor 11 is efficiently cooled, the space utilization rate of the waste disposal device 49 can be improved.
The support ring of the radiation fins 222 in which a large number of plate-like fins are arranged in a radial pattern is mounted in close contact with the casing 226 of the electric motor 11, and is installed in the semi-cylindrical space of the sirocco fan rotor 219. When the sirocco fan rotor 219 rotates to generate a suction airflow, the suction airflow cools the electric motor 11 and the radiating fins 222 and rises. to go into.
As shown in FIG. 27, FIG. 30-a to c, and FIG. 31-a to c, the electric motor 11 for rotating the sirocco fan 12 is attached to a support 225 fixed to the wall of the decompression chamber 202 to form a semi-cylindrical shape. The electric motor 11 and the radiation fins 222 were mounted inside the sirocco fan rotor 219 so that the rotation of the sirocco fan rotor 219 did not hinder the rotation.
This structure is located inside the narrow decompression chamber 202 of the waste disposal apparatus 49 and has a very high space utilization rate.

The fourth of the problems of the second embodiment is the waste crushing tank 208 and the electromagnetic discharge valve 211, which will be described below.
When the first-stage suction drying process is started, the rotation of the electric motor 11 is started, and when the suction drying is started by the rotation of the suction means, the sewage that has slipped into the sewage crushing tank 208 is removed after the previous toilet user. The washing water and the discharge water used in the defecation assist process are already accumulated in the crush tank 208, and the washing water used in the ass washing after the defecation is added, and the electric motor 11 is rotated in the crush tank 208. The crushing blade 14 that rotates at a high speed with the force collides and cuts with a small lump of filth, and is crushed into fine filth particles.
At this time, the large filth litter that has been defecation is previously crushed into a somewhat small lump by the collision with the coarse crushing plate 205 at the filth introduction unit 204, and is crushed by the collision with the rotating crushing blade 14 many times. Is performed, only a small work load is applied to the electric motor 11.
The crushing blade 14 is a knife edge and is made of a hard metal such as phosphor bronze or stainless steel. The crushing blade 14 is rotated horizontally to slice and cut the waste mass. Although the crushing blade 14 collides with the filth many times, the length of the crushing blade 14 is designed to be small and the turning radius small so as not to cause a large rotational moment. Is small. In addition, the draining noise is reduced by horizontally rotating the crushing blade 14.
The bottom of the waste crushing tank 208 may have a V-shape so that the crushing blade 14 can easily rotate and collide with the waste lumps. However, consideration must be given to a structure that facilitates drainage of waste water.

The fifth problem of the second embodiment is that when a negative pressure is generated in the decompression chamber 202, the decompression chamber 202 and the waste discharge chamber 210 are connected to each other in order to ensure the negative pressure and to ensure the suction stimulation in the defecation assist. The electromagnetic discharge valve 211 is installed at the waste water discharge port 212 of the partition wall 201.
This structure is a structure of the waste disposal apparatus 49 of the second embodiment shown in FIGS. 25 to 27 and another embodiment. If the electromagnetic discharge valve 211 is not provided, the suction means is rotated by the rotation of the electric motor 11. Then, a phenomenon occurs in which air from the sewer pipe side flows backward through the wastewater discharge port 212 to the waste discharge chamber 210, and the decompression chamber 202 cannot reach a sufficient negative pressure even if the suction means is rotated.
In order to eliminate such a phenomenon and obtain a sufficient suction capacity, an electromagnetic discharge valve 211 is attached to the waste water discharge port 212 of the partition wall 201 to create a negative pressure in the decompression chamber 203, or to perform suction urination or suction stimulation, In the suction drying process, when the electromagnetic discharge valve 211 is closed and the suction means is rotated, the backflow of air from the sewer pipe 26 can be prevented.

However, by providing the electromagnetic discharge valve 211 on the partition wall 201, in order to discharge the waste water from the waste crushing tank 208 to the drain 26, the power supply of the electromagnetic actuator 209 of the electromagnetic discharge valve 211 is turned on and the valve is opened. Thus, the waste water is taken out and discharged to the sewer pipe 26.
When the wastewater is discharged from the waste crushing tank 208 to the sewer pipe 26, the electromagnetic discharge valve 211 is only opened, and in order for the wastewater to naturally flow from the waste crush tank 208 toward the sewer pipe 26, the electromagnetic discharge valve 211 is required. Before opening, the air pressure upstream and downstream of the electromagnetic discharge valve 211 needs to be equalized.
If the air pressure is different between the upstream side and the downstream side of the electromagnetic discharge valve 211, air flows between the decompression chamber 202 and the sewer pipe 26, and the waste water flows in the direction of the sewer pipe 26 along the descending slope of the bottom for a short time. This is because sometimes it does not flow well.

As shown in FIGS. 25, 26, and 27, the valve portion of the electromagnetic discharge valve 211 in a closed state is a part of the wall of the waste crushing tank 208, and the opening of the electromagnetic discharge valve 211 is When the electromagnetic discharge valve 211 is opened, most or all of the waste water in the waste crushing tank 208 flows out to the bottom of the waste discharge chamber 210 when the waste water outlet 212 including the bottom of the waste tank 208 is closed. Therefore, the wastewater flow is designed so that there is almost no obstacle on the way, and the wastewater flows into the wastewater discharge pipe 213 inclined downward toward the sewer pipe 26.
The filth is crushed into fine filth particles, has moisture, and has a lubricating effect, so that it has a structure that can operate and open and close without impairing the function as an electromagnetic valve.
If the electromagnetic discharge valve 211 uses a liquid electromagnetic valve having a diameter of about 20 mm or more, waste water can be discharged in a short time.
As the type of the electromagnetic discharge valve 211, an electromagnetic valve such as a ball valve, a butterfly valve, a slide gate valve, and a flange valve can be used.
25, 26, and 27 show examples using a slide gate valve.
25, 26, and 27 show an example in which the electromagnetic actuator 209 of the electromagnetic discharge valve 211 is installed inside the waste discharge chamber 210, but it is also easy to install the electromagnetic actuator 209 outside the waste discharge chamber 210.

The discharged airflow that has entered the waste discharge chamber 210 enters the waste water discharge pipe 213 installed at the lower part of the waste discharge chamber 210, and the waste water in the waste water discharge pipe 213 is inclined downward by the waste water discharge pipe 213. , And is transferred to the sewer pipe 26 by the flow of the discharged airflow. The discharge airflow is also discharged to the sewer pipe 26.
The electromagnetic discharge valve 211 has a valve body closed when the power supply is in the OFF state, introduces dirt into the dirt crushing tank 208, and sets the crushing blade 14 attached to the tip of the rotating shaft 20 of the electric motor 11. During the crushing of the filth lump by rotation, and creating a negative pressure in the decompression chamber 202, suction urination, suction stimulation, suction drying, and post-cleaning process, the electromagnetic discharge valve 211 is opened by an appropriate sequence, Alternatively, it is closed.

Only when the waste water is discharged to the sewer pipe 26, as described above, the upstream and downstream of the electromagnetic discharge valve 211 are equal in pressure or almost equal in pressure. The valve body is opened, and the waste water naturally flows out of the waste crush tank 208 to the sewer pipe 26 via the waste discharge chamber 210 to the sewer pipe 26. Thereafter, when the suction means rotates in the post-washing process to send the discharged airflow to the waste discharge chamber 210, the wastewater is flushed to the sewer pipe 26 by the flow of the airflow, and at the same time, the post-wash water is discharged from the waste pool 8 to the waste crushing tank 208. The accumulated waste water can be washed off the waste flow path with fresh washing water to keep the valve body of the electromagnetic discharge valve 211 moist.

A sixth problem of the toilet system using the waste disposal apparatus of the second embodiment and the other embodiments is to prevent urine water from splashing around the toilet in the standing urinal process and becoming dirty.
When urinating in a standing position, urine water released from the urinary tract draws a parabola and falls on the odor-stopping water surface 250 of the filth pool 8, and sewage jumps on the water surface, or parabolic urine water is not necessarily a single water column. In addition, there is also urine water that partially spreads out in a conical shape and falls around the toilet, and the area around the toilet is contaminated with urine water or bounce water.
The odor control structure 69 of the toilet according to the second embodiment and other embodiments of the present application uses the structure shown in FIG.
When the suction means is rotated to reduce the pressure in the decompression chamber 202 to a negative pressure, most of the water layer serving as an odor control is sucked and dropped into the crushing tank 208. If the suction means continues to rotate during urination, urine water will not accumulate in the odor control structure 69 and will not bounce.
Since the outside air is continuously sucked from the toilet bowl 8, the suction air current sucks the splash of urine water into the crushing tank 208 and does not scatter outside the toilet.
That is, as shown in the standing urine process sequence of the present application in FIG. 44, if the suction means is continuously rotated until the urination is completed before the urination is started and the urination is performed, the urine which spreads in a conical shape and scatters Part of the water can be prevented from contaminating around the toilet.
Further, when the suction means rotates and the odor preventing water layer is sucked into the waste crushing tank 208, the water of the odor preventing structure 69 becomes completely invisible when viewed from above the filth reservoir 8. If the odor prevention structure 69 is designed, it is more effective to completely prevent bouncing.
In order to prevent the above toilet from being unsanitary in the standing urination process, as shown in the sequence in FIG. When the button is flipped upward, the limit switch (not shown) installed in the toilet seat bearing 4 of the toilet seat is turned on, the microcomputer determines that the process is a standing urinal process, and automatically turns off the electromagnetic discharge valve. Then, the electric motor 11 is turned on. When the suction means rotates to start sucking the ambient air from the waste pool 8 of the toilet, urination is completed, urination is completed, and the toilet seat 3 is lowered to the original upper position of the toilet bowl. The limit switch is turned off, and the next wastewater discharge sequence is started.

The toilet process sequence of the present application using the waste disposal apparatus 49 of the second embodiment and the other embodiments is almost the same as the sequence shown in FIGS. In the process, the defecation assist process, the suction drying process, the hot air drying process, the process of sucking and dropping filth into the crushing tank, the filth crushing process, the discharging process of filth water to the sewer pipe, and the pre / post cleaning process, FIG. A slight change is required as shown at 50.

First, since the present application is a water-saving toilet system, for the contamination of the toilet surface, if defecation is performed in a state where the toilet surface is dry, dirt may stick to the toilet surface, In order to prevent a case where it is difficult to easily wash off in a later process, a “pre-cleaning” process shown in FIG. 43 is performed, and a fourth solenoid valve is previously provided on the toilet surface before starting the toilet process. 63 is opened, and about 1 L of flush water is flown from the toilet water pipe or pipe to make it wet.
Toilet water pipes or pipes are provided so that when the user senses entry into the toilet room, flush water spreads from the upper part around the toilet to the inner surface of the toilet bowl.
In addition, when the human sensor detects that the user has left the toilet room after the entire toilet process has been completed, the washing water is placed on the inner surface of the toilet bowl in the same manner as described above as a fourth post-wash process. When the solenoid valve 63 is opened, about 3 L of flush water flows from the toilet water pipe or pipe to clean the toilet surface and at the same time to wash the waste passage of the waste treatment device 49 and to improve the lubricity of the valve body of the electromagnetic discharge valve 211. Water is stored in the waste crushing tank at a water level that maintains it.

Next, the sequence of the toilet system using the waste disposal apparatus 49 according to the second embodiment and another embodiment will be described by taking as an example a process of discharging waste water to the sewer pipe 26 from defecation by the defecation assist process. . For details, refer to the sequences shown in FIGS.
In the defecation assist sequence, "straight hot water" of the standard condition cleaning of the bidet cleaning process shown in Fig. 45 and "pulse water flow cleaning" of the buttocks cleaning of Fig. 47 are also applied to the warm water stimulation of the defecation assist. It was confirmed whether these two processes were being used during bidet washing, buttocks washing, or in the process of assisting defecation, and the system was changed to a method of incorporating them into the warm water stimulation sequence of assisting defecation.

In addition, as shown in the defecation assist process sequence in FIG. 46, a sequence in which “straight warm water stimulation”, “pulse water flow stimulation”, and “suction stimulation” are selected and commanded remotely at the start of the defecation assist process did.
In other words, it is also possible to select "suction stimulation" from the beginning,
The electromagnetic discharge valve 211 of the waste disposal apparatus 49 is turned off and the valve is closed, the electric motor 11 is turned on, and the propeller fan 203 or the sirocco fan 12 as a suction means is rotated to exhaust air from the waste pool 8 of the toilet. When the toilet user sits with both knees together, the electromagnetic discharge valve 211 of the decompression chamber 202 is closed, so that the negative pressure in the decompression chamber 202 and the waste pool 8 is secured. Toilet users felt negative stimulus of suction in the rectum and anus, improved their defecation, and improved the defecation assist process to select a process that can perform defecation assist. By making it possible to select a suction stimulus from the beginning without going through warm water stimulation, it is possible to enhance the defecation of defecation in a non-contact manner, and it is also effective for persons with diseases such as cut hemorrhoids.

In the structure of the above-mentioned toilet seat and toilet using the waste disposal apparatus 49 shown in FIGS. 26 and 27 of the second embodiment and another embodiment, when the two kneecaps are put together on the toilet seat, FIG. As shown in the image diagram in FIG. 33, the space created by the thighs becomes a substantially air-tight space. Therefore, when the electric motor 11 rotates and the suction means sucks air at high speed, the substantially air-tight space is decompressed. A negative pressure suction stimulus is felt without contacting the anus and the rectum.
When gas near the anus of the rectum is sucked into the anus, the toilet user feels strong defecation and encourages independent defecation. For a person with inadequate instinct, the warm water stimulation of the straight stream, the pulsed stream, and the suction stimulation can be repeated any number of times. As described above, in the bowel movement assisting process sequence of FIG. 46, when the user's feelings are enhanced by the above-mentioned stimulus and the self-sustaining bowel movement is performed, the process proceeds to the hip cleaning process.

The buttocks cleaning process sequence shown in FIG. 47 occurs when the toilet is seated in a relaxed position and the pulse water flow generator 38 is turned on to rapidly open the water channel and flow the water flow as shown in FIG. The shock wave is made into a shock wave in which the impact force is suppressed by the interference of the accumulator 214, and includes a shock wave of six times with a single pulse water flow discharge command as in the hot water discharge pulse flow shown in FIG. The pulsed hot water flow is discharged toward the anus, and the inside of the anal wrinkle can be sufficiently washed. You can repeat the ass washing many times.
Of course, a person who feels a strong impact can adjust the discharge force of the gear pump 30.

Next, when the process proceeds to the first-stage suction drying process shown in FIG. 48, it is confirmed that the power of the electromagnetic discharge valve 211 is OFF. If the power is ON, the power is turned OFF and the valve is closed. When the motor 11 is turned on, the pressure in the decompression chamber 202 is reduced to a negative pressure, and the air in the sewage pool 8 of the toilet is sucked. Then, as shown in FIG. An airflow is generated that is sucked into the toilet from between the thighs.
The suction airflow passes through the anterior part from the anterior genital area, reaches the fan of the suction means installed in the waste disposal device 49 from the waste outlet 9 of the toilet bowl, passes through the waste discharge chamber 210, and is discharged to the sewer pipe 26.
At this time, most of the water that wets the pubic area and anal area is in the form of water droplets attached to or adsorbing to the pubic hair and skin. And is mechanically removed.

During the suction drying process, which is the first drying process, when the pressure in the decompression chamber 202 of the waste disposal device 49 becomes a negative pressure exceeding the pressure difference of the water layer thickness of the odor control structure 69, the odor control structure 69 is activated. The water layer is broken, and the dirt and the cleaning water in the dirt pool 8 of the toilet bowl are dropped into the dirt introduction part 204, and the large dirt mass collides with the coarse crushing plate 205 to become a small lump of dirt and the sliding water 207 together with the cleaning water. To fall into the waste crushing tank 208.
In the filth crushing tank 208, the crushing blade 14 attached to the tip of the rotary shaft 20 of the electric motor 11 is rotating at high speed, and the filth lump becomes filth water mixed with washing water and air.
Since the present application does not use toilet paper, it is possible to use the crushing blade 14 to turn the waste into highly fluid wastewater mixed with fine particles.

In the water-saving toilet system of the present application, in the above-mentioned waste crushing process, if the amount of the liquid component is too small in the crushing tank 208, there is a possibility that sewage cannot be successfully crushed. In order to avoid such troubles, a water level gauge is installed in the crushing tank 208, the crushing process is started only when there is a liquid component above a certain water level, and when the water level does not reach the certain water level, the fourth step is performed. It is also a good method to open the electromagnetic valve 63 and inject water into the crushing tank 208 to increase the liquid component to a certain level.
The process of turning the waste into waste water is performed during the first stage suction drying, as shown in FIG.

Next, the process proceeds to a hot-air drying process, which is a second-stage drying process shown in FIG. 49, in which hot air is blown out from a nozzle toward a local portion, and moisture remaining on the skin surface is dried with the hot air.
In order to prevent the stench of the filth pool 8 from coming up on the face, the fan of the suction means is rotated at a low speed at the same time as the hot air is discharged from the nozzle 57, so that the speed is slightly lower than the hot air discharge speed. Air is suctioned by suction means.
When the second-stage hot-air drying process is completed and the rotation of the electric motor 11 is stopped, the air from the toilet and the sewer pipe flows into the decompression chamber 202, and the waste discharge chamber 210 becomes atmospheric pressure. When the valve 211 is opened, the waste water spontaneously flows out, flows toward the sewer pipe 26 along the slope of the pipe, and the waste water discharge sequence shown in FIG. 50 is started.
In the drying process, when the toilet user feels that the area is completely dry, he issues a command of "end", stands up, prepares clothes, and exits the toilet room.
When the "end" command is issued and the user leaves the toilet room and the motion sensor detects "exit", the post-washing process of FIG. 43 is started.

The process sequence of discharging waste water according to the second embodiment and the other embodiment shown in FIG. 50 will be described. When the rotation of the electric motor 11 is automatically turned off, the air flows in from the toilet and the sewer pipe. Then, the decompression chamber 202 becomes the atmospheric pressure, the upstream and downstream of the electromagnetic discharge valve 211 become the same pressure of the atmospheric pressure, and then, when the electromagnetic discharge valve 211 is opened, the waste water is discharged from the bottom of the waste discharge chamber 210. The water flows along the descending slope, and most or all of the wastewater is discharged to the drain 26.
The power of the electromagnetic discharge valve 211 is automatically turned off again in about 10 seconds, and the electromagnetic discharge valve 211 is closed, thereby completing the waste discharging process.
