Description

The present invention relates to a suction-type flush toilet system including a butt washing hot water nozzle and a hot air drying nozzle, and a suction means that is rotated by an electric motor, a waste crushing device, a gas / liquid under the outlet of the toilet A waste disposal device with a separation mechanism is connected, defecation assistance including suction stimulation, suction drying that cleans the local area with pulsed water flow, and drying in a short time, and a toilet bowl with standing urine using suction force The present invention relates to a defecation assist suction flush toilet system having a function of preventing surrounding contamination.

It is known that high-concentration pathogens are found in the stool of persons affected by infectious harmful bacteria (norovirus, rotavirus, salmonella, O-157, E. coli, etc.). If a person suffering from infectious harmful bacteria uses a conventional flush toilet and hand-washing equipment inside or outside the toilet, hands that are contaminated with pathogens after wiping feces with toilet paper, various switches with fingers, flush flush knob, Many cases have been reported by the Ministry of Health, Labor and Welfare and the National Institute of Infectious Diseases that have been secondary contaminated by touching toilet seat lids, hand-washing faucets, common towels, door knobs, door locks, and patient clothes, and have spread to mass food poisoning. . In addition, cases have been reported in which elderly people die from vascular disorders such as heart disease, cerebral hemorrhage, and cerebral infarction when they breathe defecation in the toilet. Defecation and the wiping of the hips after defecation are very difficult for elderly people and people with disabilities such as involuntary cerebral disabilities, and severely ill people must wipe off the local area after defecation. There is also a problem of an aging society. Another problem is that the toilet area is unsanitary in standing urine. In view of this fact, there has been a long-awaited demand for a toilet that has a mechanism for assisting smooth evacuation when a flush toilet is used and does not require the operation of wiping the butt with toilet paper.

This application is a patent application that has been improved by the same inventor as Patent Document 14 with a different solution to the object of the same invention.

The conventional flush toilet apparatus provided with the butt washing hot water nozzle and the hot air drying nozzle has the following problems.
In other words, the first problem was that when the anus was wiped with toilet paper after washing the local area with conventional hot water shower washing, the hot water shower washing was often incomplete so that the residue of filth was attached to the toilet paper. .
In addition, the second problem is that in the method in which the hot water shower is washed and then dried hot air is blown locally, the hot water is dried for a long time to feel that the hot water shower washed portion is “completely dry”. There was a problem that it was difficult to use and that the toilet user could not wait.
As a result, toilet users do not get a complete local cleanliness, and the anal area after washing with a hot water shower to remove the discomfort of getting wet or wet around the anus and genital area It is customary to wipe it with toilet paper, and hot air drying is not widely used in the world.
Therefore, the third problem is that the contamination and spread of the infectious pathogen described above does not eliminate the "wiping the buttocks with toilet paper" work that is a cause of mass food poisoning even in the present when the toilet system has been developed. It is.
In addition, the fourth problem was reported to be a case of a person who suffered from a brain disorder and had a sequelae of his / her body and an elderly person who had weak abdominal muscles. Also, it is not easy to wipe the hips after defecation.
The fifth problem is that conventional vacuum flush toilets are used for toilets of airplanes and Shinkansen trains, but the system cannot be used for home use as it is. Further, in the patent document, an application example is disclosed mainly for nursing care using a large vacuum pump, but there is a problem that the caregiver's hand is bothered and the system is large and expensive with a complicated system. As a sixth problem, it has been a long-standing problem to make the urinal area unsanitary by splashing urine in the standing urination process.

The solution of the present application is to devise the shape and structure of the toilet seat and toilet bowl, so that when the toilet user sits on the toilet seat, the toilet bowl becomes a substantially airtight space, and the suction means and filth crushing at the lower part of the toilet bowl portion To develop a process sequence to solve the problem by managing and controlling a toilet system having a device and a waste disposal device having gas-liquid separation means with a microcomputer.

This application solves the above-mentioned six problems of flush toilets with hot water washing and hot air drying devices, and has realized a toilet system that does not use toilet paper. By fundamentally solving the problem, and eliminating urination in the suction airflow, the contamination around the toilet bowl is eliminated.Furthermore, the defecation movement of the disabled and elderly people whose abdominal muscle strength has been weakened can be smoothly defecationed. After defecation, sufficient buttocks washing and complete drying in a short period of time are possible, and filth is discharged into the sewage pipes with the flow of washing water and exhaust airflow to make toilets that do not use toilet paper. It can be expected to bring about a significant load reduction.

The method of solving the problem to achieve the object of the present application is a filth having a pulse generator for sufficiently washing after defecation and an electric motor for driving a suction means for sucking and discharging air from a sewage pool at a toilet outlet. Connect the treatment device, combine the functions of the inline hot water creation device and hot air creation device to create a mechanism of defecation assistance, pulsed water washing, and rapid drying, and mix the filth and washing water excreted in the toilet bowl Finely pulverizing rotary blades, suction means, and auxiliary rotor blades for gas / liquid separation means are installed through the rotating shaft of one electric motor to cool the electric motor strongly with separated clean air Then, it is to develop a filth processing device that discharges sewage liquid to the sewage pipe and discharges the sewage liquid to the sewage pipe, and to develop a toilet system that controls the toilet process sequence with a microcomputer.

Fig. 1 shows the overall configuration of the defecation assist suction flush toilet of the present application, Fig. 14 shows a system control system diagram, and Fig. 15 shows a whole toilet process flowchart.
The toilet process sequence includes a preparation process and a main process sequence.

As shown in FIGS. 5 and 6, the toilet bowl 48 and toilet seat 3 of the present application are provided with water-repellent resin layers 5 and 6 on at least one or both of the upper peripheral edge 7 of the toilet bowl 48 and 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.
In addition, the toilet seat shape is raised in an inverted V shape at the center line of the front of the toilet seat as shown in FIGS. 6, 6-a, 6-b, and 6-c, and the thigh and toilet seat of the toilet user are It is a shape that fills the space of the triangle to be created.

1 and 2 show a waste disposal apparatus 49. FIG.
A silent sirocco fan 12 that creates a suction airflow and a rotating body 13 of a filth crushing blade 14 are installed on a rotating shaft 20 of a single electric motor 11, and the filth and washing water excreted in the filth reservoir 8 of the toilet 48 are When the electric motor 11 rotates at a high speed and the sirocco fan 12 rotates, the electric motor 11 falls into the crushing groove 16 of the waste crushing device 49 together with the suction airflow. The dirt is pulverized by the rotation of the pulverizing blade 14 in the pulverizing groove 16, and the suction airflow and the filth water flow into the cyclone 18 over the outer wall 68 of the pulverizing groove 16 by centrifugal force. It does not flow into the cyclone 18 because of the filth lump inflow prevention wire mesh 90 provided on the outer wall 68 of the groove. When the filth water containing the filth crushed into fine particles enters the suction airflow and the cyclone 18, gas / liquid separation is performed by centrifugal force.
At the center of the cyclone 18, an air take-out pipe 22 for taking out the purified gas to the outside is installed, and the rotating shaft 20 of the electric motor 11 passes through the center. Since the auxiliary wing 21 is installed on the rotating shaft 20 and rotates at the same rotational speed as that of the electric motor 11, the clean gas at the center of the cyclone device 18 is strongly sucked and the air is pushed out. The clean air is guided to the hood 29 surrounding the electric motor 11 and is used for cooling the electric motor 11.
Since the sirocco fan 12, the crushing blade 14, and the auxiliary blade 21 installed on the rotating shaft 20 of the electric motor 11 are rotating at the same time, the above processing is performed simultaneously.

The electric motor 11 is a 50 to 500 Watt electric motor 11 used as a household power supply, has an output variable control circuit using a PWM control circuit, and has a “suction force adjustment dial” 127 on the “defecation assist” command board 115. It can be adjusted to the suction force you want.
The microcomputer is programmed with a standard rotation of the electric motor 11 as the process progresses. In the “second stage drying” process, the suction speed (M ³ / min) of the electric motor 11 is the amount of discharge of dry hot air. The microcomputer commands the low-speed rotation that does not exceed the speed. However, it is reset to normal rotation at the end of the process.

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

The warm air used for drying is produced by an in-line warm air creating device 59, and includes a blower fan 50 for blowing air in-line, an in-line warm air temperature sensor 54, a heater unit 53, and a heating control unit 59. As with the hot water, the temperature was controlled at an appropriate temperature of 38 ° C and an appropriate temperature range of ± 2 ° C. Alternatively, it is also effective for warm air drying to design the temperature higher than the hot water temperature to speed up drying. However, you must consider the risk of burns.

The warm water cleaning cylinder / nozzle includes bidet cleaning 42 and 43 and buttocks cleaning 40 and 41, and a pulse water flow generator 38 is disposed immediately before the buttocks cleaning cylinder 40.
The pulse cleaning is prepared for the butt cleaning and the defecation assist under the standard conditions shown in FIG. 7 for the straight water flow and the pulse water flow.

The bidet cleaning cylinder nozzles 42 and 43 discharge a straight water stream and are also used for bidet cleaning applications and “warm water stimulation” for defecation assistance.

The method of 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 with the on-off valve fully closed, or to fully open to maximize the water flow. Thus, a pulsed water stream 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 the water flow.
FIGS. 9A and 9B show a cylindrical rotating body in which the on-off valve 95 is cylindrical and intersects at right angles to the buttocks washing hot water pipe 45, has a cylindrical hole with 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.
With a single ON pulse 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 turned OFF for 2 seconds, the fully open state of the water flow for 2 seconds is changed. Then, when the cylindrical rotary valve 95 rotates 90 degrees with the next electric signal ON pulse, the water flow becomes a fully closed state, and when the signal is OFF for 2 seconds, a fully closed pulsed water flow is generated for 2 seconds. By repeating this, the pulse water flow shown in FIG. 7 can be obtained. Other forms can create a similar pulsed water flow using a ball valve.
In addition to the two types of pulsed water flow generators shown in FIGS. 8 and 9, the normal ON / OFF valve shown in FIG. 10 can form a pulse waveform, but the 0 ring 97 on the contact surface of the valve can withstand many uses. There are no drawbacks.

The purpose of defecation assist is to stimulate the anus by means of stimulation of the anus by straight water flow or pulse water flow and to promote self-defecation as described later. The straight water flow 123 or pulse water flow 124 is selected remotely by the toilet user. Do.

In addition, pulsed water flow is a standard condition for butt washing after defecation, and a pulse-like thick water flow is intermittently discharged to the vagina of the anus, and washing is performed by closing and opening the anus. Then, effective cleaning can be performed.
However, a thick pulsed water flow is desirable because a thin pulsed water flow may damage the anal mucosa and bleed. It should be noted that during washing, the hips are moved slightly from side to side and back and forth, and pulse washing is not continued for a long time at the same location.
A thick water stream with a diameter of about 10 mm is used for the cleaning application of the present application.

In the storage-type hot water producing device, when the consumption of hot water increases, cold water is discharged, which is uncomfortable. In order to avoid this phenomenon, it is better to use an in-line type hot water preparation device.

The rapid drying process is performed in two stages. Since most of the water adheres to the pubic hair and skin in the form of water droplets in the wet part when the local area is washed, when the “drying” command 119 starts “drying of the first stage”, the waste disposal apparatus The sirocco fan 12 is rotated by the rotation of the electric motor 11 of 49, and the air in the septic pool 8 of the toilet bowl is sucked at 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 is concentrated between the thighs of the toilet user and flows into the genital area and the buttocks area. For this reason, the pubic hair and skin vibrate violently, and the attached water droplets are mechanically shaken off in a short time.

The subsequent second stage of “drying” is a process of drying the wetted part with a large amount of hot air. After the “first stage of suction drying” process, a slight amount of moisture remaining on the skin surface is removed. Dry quickly with hot air discharge. At this time, the sirocco fan 12 of the waste disposal device 49 rotates at a low speed and sucks from the waste discharge port 9 of the toilet 48 with a suction air flow slightly smaller than the discharge amount of the hot air nozzle, so that the hot air dries the local surface. The electric motor 11 and the sirocco fan 12 are programmed to rotate by suction to such an extent that they do not decrease.

As an output variable control device for 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 a person sitting on the toilet seat 3, to promote defecation and to assist defecation, and the pulse water flow generator 38 also sufficiently cleans the anus after defecation. We were able to complete the process of drying the drying area in a short time.
As a result, we have completed a defecation assist suction flush toilet system that eliminates the need to wipe the buttocks with toilet paper and solves the problems associated with conventional flush toilets.

As described above, since the electric motor 11 rotates in each process, the sirocco fan 12, the pulverizing rotary blade 14, and the cyclone auxiliary blade 21 are rotated each time, and all toilet processes are performed even when filth remains in the pulverizing groove 16. There is an opportunity to perform the waste disposal process many times before the end of the operation, and all the waste can be discharged into the sewer pipe 26.

The toilet bowl 48 according to the present application does not have a flush knob for discharging filth after the toilet is finished, unlike a conventional flush toilet, does not require a flush water tank, and does not require a siphon structure. As a highly functional toilet system, it becomes a simple and small toilet.

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 sequence is the “warm water discharge standby” sequence shown in FIG. 16, and as shown in FIGS. 1 and 4, the heater 32 is disposed in-line in the middle of the pipe 33 through which the supply water flows. The PID control is independently performed by the temperature sensor 34 and the heating temperature control device 39, and the device is ON / OFF controlled by the microcomputer, which is shown in the “hot water discharge standby” sequence in FIG. As described above, the hot water that does not fall within the proper temperature range is discharged by switching to the direction in which the second electromagnetic three-way valve 36 is discharged to the filth reservoir 8 so that only the warm water that falls within the proper temperature range is discharged to the cleaning unit. If the command to start the process using hot water is not issued even if the temperature is within the appropriate temperature range, the hot water is discharged to the filth reservoir 8 and T Low is set to 36 degrees C and T High is set to 40 degrees C. Is suitable around 38 degrees C Only the warm water of the width so as to discharge towards the human body. However, the discharge warm water speed during standby is about 1/2 of the specified discharge hot water speed, and if there is a discharge command, 100% of the supply water will increase the rotation of the gear pump 30 and inline hot water heating. It is sent to the heater 32, and hot water at a designed amount is discharged to the cleaning part.
Accordingly, it is possible to discharge hot water at a specified amount speed with an appropriate temperature range from the beginning of discharge toward the cleaning site. For example, as an in-line hot water generator 39
http://www.nippon-heater.co.jp/products/liquid/sgl/

The second of the preparation sequence is a “warm air discharge standby” sequence. As shown in FIGS. 1 and 4, an in-line hot air generator 51 having a blower fan 50 itself inputs a signal from the temperature sensor 54. Thus, an independent temperature control circuit 59 is provided so that warm air of a set temperature range is generated by the heater device 53, and ON / OFF of the device is controlled by a microcomputer. The appropriate temperature range of the warm air is also set to the same temperature as the warm water, and the warm air that is not within the set temperature range and the warm air during the period when the dry warm air command is not received are passed through the sewer pipe 58 by the third three-way solenoid valve 55. Has been released. However, the discharge warm air speed is set at about 1/2 of the design air speed, and it is on standby. After receiving the dry warm air command, it is switched to 100% of the design air speed to waste energy. Less.
Therefore, it is possible to discharge at a designed amount speed with an appropriate temperature range from the beginning of discharging hot air.
For example, as in-line hot air generators 51, 53, 59
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 device structure diagram of the present application shown in FIG. 1 can be switched in three directions https://www.valco.co.jp/ There are T3 type AE1-120 of product / general-ball / T3.html.
The electromagnetic valve 63 is a general purpose two-way electromagnetic valve.

In the toilet process of this application, the standard conditions are programmed in the microcomputer, and it is possible to change the process conditions remotely. When the end of the sequence is instructed by the process “end” command, the sequence is reset to the standard conditions again. Yes.

The first of the main process sequence of this application is the “standing urinal process” shown in FIG. 18. When a toilet user enters the toilet room, the human sensor detects it, but the seat sensor detects it without sitting on the toilet seat. Otherwise, the microcomputer determines that it is a “standing piss process”.
Then, during the execution of the “standing urinal process”, even if a sequence start command of another process is erroneously pressed, it is not “started” and the sequence is locked. The sequences to be locked are “butt washing”, “bidet washing”, “defecation assistance”, and “drying sequence”.
However, when the “standing piss process” is “finished”, the sequence lock is released.

It goes without saying that the “standing urinal process” sequence is not initiated when the seating sensor senses it.
When the “piss urine” action is performed and the “piss discharge” command switch 113 is pressed, the electric motor 11 is driven to rotate the sirocco fan 12, and the filth water is sucked from the filth reservoir 8. The electromagnetic valve 63 is opened for about 10 seconds along the container wall of the filth reservoir 8 and washing water flows from the upper edge 7 of the toilet, and the filth water drops and moves to the crushing groove 16 of the filth treatment device 49.
The liquid level of the waste liquid becomes higher than the outer wall 68 of the crushing groove 16 due to the strong suction air flow and the rotational centrifugal force of the crushing blade 14, and flows into the cyclone introduction path 17 beyond the outer wall 68. The waste liquid flows from the tangential direction of the cyclone 18, and the air and liquid components are separated by the centrifugal force of the high-speed vortex airflow of the cyclone 18. The liquid components are 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 the sewage pipe 26 through the sewage pipe 25. Moreover, an air component is taken out from the air extraction pipe | tube 22 provided in the cyclone center part. A filth prevention cover 19 is attached to the upper portion of the air extraction pipe 22 so that filth water does not enter.
The rotary shaft 20 of the electric motor 11 passes through the center of the air extraction pipe 22, and the auxiliary wing 21 is installed on the rotary shaft 20. The auxiliary wing 21 installed on the rotary shaft 20 of the electric motor 11 rotates in the same manner as the electric motor 11, and strongly sucks / push out clean air not mixed with liquid components in the center of the cyclone, and is electrically driven by the clean air pipe 24. The electric motor 11 is cooled by being conveyed to the hood 29 of the motor 11 and then discharged to the sewer pipe 26 through the air discharge pipe 27.

The “piss discharge” command switch 113 is automatically turned off after 10 seconds, at the same time the sequence lock is released, and the “piss discharge” sequence is automatically “finished”.
When the toilet user exits, the human sensor detects the exit, and the “post-cleaning” sequence shown in FIG. 24 is automatically performed, and the fourth electromagnetic valve 63 is opened from the upper part of the filth reservoir 8 of the toilet 48. It opens and flows about 3 L of cleaning water, cleaning the sewage residue on the toilet bowl surface and the sewage reservoir 8 surface, and collecting the cleaning water in the toilet bowl scent stop 69 to prevent the smell of odors from the sewage treatment device 49. To do. The fourth solenoid valve 63 is automatically turned off after 5 seconds.
This completes the “standing urination process”.

The second main process is the “bidet cleaning” process sequence shown in FIG. 19, and the “warm water discharge standby” preparation process shown in FIG. 16 is performed as shown in FIG. If the “Discharge standby” sequence is activated and a “warm water discharge” command is issued, hot water of an appropriate temperature can be discharged from the nozzle at any time.
When there is an instruction 114 to start “bidet cleaning”, the second three-way valve 36 is switched to the bidet nozzle pipe, hot water having an appropriate temperature range is supplied to the bidet cylinder nozzles 42 and 43, and a straight water flow is discharged from the bidet nozzle 43. The
Bidet washing is a straight stream of warm water that can change the water pressure of the standard condition with the remote 117, 118, and is stored when the water condition is changed. When the “Bidet Cleaning” command is pressed again, the microcomputer determines that “Re-washing for bidet cleaning” is performed by the same toilet user, and the sequence is such that the memory conditions are recalled and cleaning is performed under the same conditions as the previous cleaning conditions. It is a user-friendly system for users. When the bidet cleaning process is completed, the process proceeds to the “first-stage suction drying” and “second-stage hot air drying” processes described later.

When the bidet cleaning and drying are finished and the toilet user leaves the toilet seat, the seating sensor “detects sitting”, the memory of the cleaning condition disappears, and the standard condition is reset.

The third sequence is “defecation assist” shown in FIG. 20. Elderly persons with weak abdominal muscle strength or disabled persons give warm water stimulation and suction stimulation to the buttocks to enhance their constipation and perform self-defecation. It is a sequence that helps.
“Straight warm water flow stimulation” 123 and “pulse warm water flow stimulation” 124 are selected from the “defecation assist” command board 115, and the command switches of “warm water discharge stop” 125 and “suction stimulation” 126 are remote. It is prepared in. When the “defecation assist” command board 115 shown in FIG. 13 is installed independently of other command boards, it is easy for the toilet user to understand.

That is, when sitting on the toilet seat 3 and the toilet bowl 48 having the structure proposed in this application and defecation is performed, first, a person who can defecate by himself performs defecation by himself, but a person having low constipation performs “straight hot water flow stimulation” 123 toward the anus. In the standard condition, warm water of a straight water flow is discharged from the bidet hot water discharge nozzle 43 toward the anus. Toilet users adjust so that hot water hits the buttocks.

If you want to stimulate the anus with pulsed warm water stimulation and enhance the stool of defecation, if you select the "pulse warm water flow stimulation" command 124, the three-way solenoid valve 35 is switched and hot water is supplied to the buttocks washing pipe Then, the pulse water flow generator 38 is operated, and the same “pulse hot water flow stimulation” mode as the pulse hot water flow after defecation shown in FIG.
When the stool is enhanced by the warm water stimulation and defecation is possible by itself, the hot water discharge is stopped by the “warm water discharge stop” command 125 and “defecation” is performed.

In addition, when the bowel movement is unsatisfactory, 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 in the filth reservoir 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,
Sitting on the toilet seat, placing the thigh in a shallow U-shaped groove 66 and sitting with the knees closed with both knee heads in contact with each other, a substantially triangular space on the center line formed by the thigh and toilet seat is the toilet seat As shown in FIGS. 1, 5, 6, and 6-a to c, the toilet seat 3 and the water-repellent resin layers 5, 6 at the top of the toilet are brought into contact with each other so that the toilet 48 and the toilet seat 3 Since the gap is closed, the filth reservoir 8 of the toilet 48 is substantially airtight.

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

If stool or gas that has come down to the rectum near the anus tries to get out of the anus, the stool will be lifted and “defecation” will be executed.
Except when giving suction stimulation with defecation assistance, it goes without saying that the posture of sitting on the toilet seat is as usual, with both knee heads widened to the shoulder width and relaxed.

However, for those who still lack convenience, it is a sequence that can repeatedly stimulate the rectum and anus by repeating "warm water stimulation" and "suction stimulation". Therefore, it is effective for people who have difficulty in defecation.

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

When the defecation is completed, the process proceeds to the “butt cleaning” process shown in FIG.
The fourth sequence is the “butt cleaning” process shown in FIG. 21. When the “butt cleaning” command 116 is issued, the first electromagnetic three-way valve 35 is turned off in the direction of passing water through the buttocks cleaning cylinder 40. Instead, the hot water produced 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. 8-a to 10-b, and the nozzle 40 under the standard pulse water flow conditions. 41, a thick hot water flow 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 pulse water flow shown in FIG. 7 is a pattern 100 in which a straight water flow 99 flows for about 5 seconds, then pauses for 2 seconds, and a pulsed warm water flow that passes for 2 seconds is repeated 5 times. It is possible to change the water condition from the standard condition to “stronger” or “weaker” by washing off the dirt attached to the detail of the anal fistula with the ON / OFF shock wave. If the water condition is changed, remember the condition. Re-cleaning is a sequence for recalling the memory and cleaning under the previous conditions.
The ON / OFF condition that determines the pulse width of the pulsed water flow generator 38 is operated by inputting a pattern into the microcomputer in advance.
Since the in-line hot water generators 32 and 39 are used, hot water can be repeatedly discharged and washed as long as necessary, and sufficient butt washing can be performed.

FIGS. 8-a to 10-b show the full-open water and fully-closed water states of the three types of pulsed water flow generators 38, respectively, and in the embodiment, shown in FIGS. 8-1a and 8-1b. A pulsed water flow generator was used. Although the pulse water flow shown in FIG. 7 can be generated by three types of pulse generators 38, the pulse generator 38 in the form of FIGS. 8 and 9 has a structure that is resistant to wear and can withstand long use.

The fifth sequence is the “first suction drying” process sequence shown in FIG.
When the sirocco fan 12 is rotated by the rotation of the electric motor 11 and the air in the filth reservoir 8 is sucked, the suction airflow passes between the thighs of the person sitting on the toilet seat 3 and concentrates on the pubic area and the buttocks. Pass while shaking the pubic hair and skin. At that time, water droplets adhering to the pubic hair and skin are mechanically shaken off. Since most of the water wetted by the washing process and stimulation of the buttocks is present in the buttock and genital area in the form of water droplets, most of the water is removed by the suction airflow.

The “first-stage suction drying process” in FIG. 22 is “started” when the “dry” command 119 is pressed, and “hot-air discharge” in FIG. 17 is prepared in preparation for “second-stage hot air drying” in FIG. The “standby” process is started.
At the same time, the filth discharged in the filth reservoir 8 of the toilet 48 is sucked into the filth treatment device 49 together with the washing water.
When the sirocco fan 12 rotates, 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 a plurality of crushing blades 14 installed on the rotating shaft 20 of the electric motor 11 is operated at high speed. Since it is rotating, the filth is finely crushed and becomes as fine as if it was crushed with a mixer.
The crushing groove 16 has a depth, and feces are crushed for a while in the crushing groove 16, but are pulverized to a fine state when rotated several tens of times by a plurality of crushing blades 14, and have buoyancy and centrifugal force. When the liquid level of the waste water rises beyond the height of the outer wall 68 of the crushing groove 16, it enters the cyclone device 18 from 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 is input from the tangential direction of the cylindrical cyclone 18, the fine dirt and the suction airflow are swirled at high speed in the cyclone 18.
In the cyclone 18, the fine filth and liquid components are driven by the vortex-rotating airflow and are pushed down the vessel wall of the cyclone 18, gathered downward along the vessel wall, and flow into the filth water discharge pipe 23 provided at the lower part of the cyclone, It is discharged to the sewage pipe 26 through the sewage pipe 25.

On the other hand, the clean air component from which fine dirt has been removed is taken out of the cyclone device 18 from the center of the cyclone 18 through the air extraction pipe 22. The rotary shaft 20 of the electric motor 11 attached to the upper part of the waste disposal device 49 passes through the center of the air extraction pipe 22, and the auxiliary wing 21 attached to the rotary shaft 20 rotates at high speed and has strong air. The clean air cools the electric motor 11 because the clean air pipe 24 is connected to the electric motor hood 29 that surrounds the electric motor 11 by generating suction force and air pushing force. Thereafter, it is discharged to the sewer pipe 26 through the air discharge pipe 27.

The sixth sequence is “second stage warm air drying” shown in FIG. 23. In the first stage suction drying process, the electric motor 11 is automatically turned off after 10 seconds, and at the same time, the electric motor 11 is automatically turned on again. The sequence is such that the rotation starts.
In the “second stage warm air drying”, the output of the electric motor 11 is reduced, and the sirocco fan 12 rotates at a low speed and sucks a suction amount speed slightly smaller than the warm air discharge amount speed from the filth reservoir 8.
This is a contrivance that does not lose the drying effect of the hot air drying and that the bad smell does not rise to 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. On the other hand, if the amount of hot air discharged from the nozzle is overwhelmingly larger than the suction amount, This is because the foul odor of the filth pool comes up.
The microcomputer is programmed to rotate the sirocco fan 12 at a low speed while keeping the output of the electric motor 11 low.
The hot air discharge rate and the suction rate are determined at the design stage.

By installing a pressure sensor that detects the differential pressure between the filth reservoir side and the atmosphere side, this delicate balance is set to be faster than the hot air discharge rate from the nozzle so that the filth reservoir is slightly positive with respect to atmospheric pressure. A method of controlling the rotation with a microcomputer so as to slightly reduce the suction speed by the sirocco fan is also conceivable.

In the first-stage and second-stage drying sequences shown in FIGS. 22 and 23, the hot-air discharge standby is started when the in-line hot-air creating devices 51, 53, 59 command 119 “drying”. Therefore, it is in a state where hot air can be discharged immediately for the second stage of drying.
When the electric motor 11 starts the low-speed rotation designed in the microcomputer, the hot air discharge from the hot air nozzle 57 starts simultaneously.
Since the rotation of the electric motor 11 is programmed in the microcomputer so that the air volume speed slightly less than the discharge speed of the hot air is sucked from the waste disposal device 49, the surface of the skin at the site to be cleaned by "warm air drying" Moisture remaining in the water is quickly dried.
It can be continued until the toilet user feels “dry” in the second stage of drying, and pressing “Finish” 120 ends the “second stage of drying” process.
The electric motor power and the in-line hot air power supply are turned off.

The toilet user prepares himself / herself, leaves the toilet room, and starts the “post-cleaning” sequence shown in FIG. 24 when the human sensor or the toilet seat seating sensor senses separation.

As described above, the “post-cleaning” serves to clean the filth adhering to the surface of the filth reservoir 8 of the toilet 48, so that the fourth electromagnetic valve 63 is turned on and the filth reservoir 8 is placed above the filth reservoir 8. After the installation, about 3 L of washing water flows from the washing outlet 62 and flows along the inner surface of the filth reservoir 8 to wash the inside of the toilet bowl. The washing water collects in the toilet smell stop 69 and the crushing groove 16. It serves as a odor odor stoper from the waste disposal device 49.
All sequences of the toilet process are completed as described above.

As shown in FIG. 14, the toilet system of the present application is intensively managed by a microcomputer control circuit, and a sequence is programmed.
Warm water and hot air temperature sensor signals, human sensor and seating sensor signals, process start and end commands from remote switches 113, 114, 116, 119, 120 and hot water flow stimulation modes 123, 124, 125, A command signal for changing the washing water flow 117, 118 is input to the microcomputer in the middle of the sequence, or the high speed / low speed rotation control 126, 127 of the sirocco fan 12 is changed. In addition, a standard condition is reset in the microcomputer so that the process that has changed the condition when the “end” command is pressed is reset to the standard condition.
The power source of the electric motor 11 of the waste disposal device 49, the electromagnetic valve 63 including the electromagnetic three-way valves 35, 36 and 5 and the piping system power source, the hot water and hot air inline heating device system power sources 39 and 59, and the device power source of the pulse water flow generator 38 Is controlled from the microcomputer control circuit according to the process sequence to the power supply of all devices via the relay block,
The temperature control of the inline hot water device 39 and the inline hot air device 59 has an independent control circuit locally, but operates according to a sequence controlled by the microcomputer control circuit.

When hot water and warm air show temperatures exceeding 45 degrees C, it is determined that there is an abnormality, and the emergency stop that stops the power supply from the microcomputer control circuit is given priority in the emergency state at the time of abnormality. Have.

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

In the previous application, the water system used in the buttocks cleaning process is shown in FIGS. 1 and 4, and FIG. 7 shows the substantially rectangular wave buttocks cleaning discharge water pressure.
In the second embodiment of the present application, the water system using the pressure reducing valve 215 and the accumulator 214 is specified in FIGS. 25 and 35 in the water system diagram of the toilet system.
The details of the pulse water flow discharge water pressure waveform of FIG. 7 are shown in FIG.
Although not described in the previous application, the pressure reducing valve is used for the main pipe of the cleaning water system, the water pressure of the entire nozzle water system is adjusted to a low water pressure, and the accumulator 214 is connected to the bidet pipe and the buttocks cleaning pipe. It is installed at the closest position upstream of the open / close solenoid valve.

In the previous application, the accumulator was not considered to directly affect the toilet function in FIGS. 1 and 4, and the pulse water flow generator 38 that suddenly closes and opens the water channel in the water system is used. It is assumed that it is understood that it is naturally used even if it is not described, so that the pressure reducing valve and the accumulator are not described, and a simplified rectangular wave simplified in FIG. 7 without any explanation. The pulse water flow is discharged to the anus, and actually, the pressure reducing valve 215 and the accumulator 214 are used.
In the previous application and the second embodiment of the present application, the pulse water flow generator 38 and the water hammer accumulator 214 interfere with each other to generate a suppressed impact force and a high cleaning ability remains. Pulsed hot water containing shock waves is used for butt washing.

In paragraph 0040 of the previous application, even in the defecation assist process, when a command of “pulse warm water flow stimulation” is issued once remotely, a hot water flow similar to the butt cleaning shown in FIG. 7 is discharged. It is described.
Further, in paragraph 0046, “The flow pattern of the standard pulsed water flow shown in FIG. 7 is that the straight water flow 99 flows for about 5 seconds, then pauses for 2 seconds, and the pulsed warm water flow that passes for 2 seconds is 5 times. The pattern 100 is repeated, and the filth attached to the detail of the anal heel is washed off with a shock wave that turns on and off.
FIG. 40, which will be described in detail below, expresses that a pulse flow including a shock wave with a reduced impact force included in the rising period of the pulse water flow when ON is cleaned under standard conditions.

Again, in the previous application and in the second embodiment of the present application, the defecation assist, the pulsed water flow generator 38 used for the buttocks cleaning process, and the water hammer phenomenon that occurs at ON / OFF are prevented. In order to deepen the understanding of 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 portion, the following description will be given.

In general, rapid opening and closing operations in water pipes that flow city water with high water pressure, such as home baths, washing machines, water heaters, toilet facilities, industrial air conditioners, and plant facilities In a case where the valve body for performing the operation is installed, a water hammer phenomenon occurs unless water countermeasures are taken, and in the worst case, a shock wave is generated so as to destroy the water system equipment shown in FIG. Known.
Regarding water hammer phenomenon, refer to “Water hammer pattern classification” FE-06-IG-001, N.Miyamoto

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

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

The shock wave generated by ON / OFF of the pulse water flow generator 38 and the effect of the accumulator 214 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 in order to wash sensitive parts of the human body. However, since it is rapidly opened and closed using the pulse water flow generator 38, it is a water system that generates a strong shock wave at a low water pressure and is worried about damaging a local part of the human body.
First, 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 in the low-pressure water system of the second application of the previous application or the present application for illustration, Consider a model water system like 37.
In the previous application and the present application, 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 electromagnetic valve 242 performing the rapid opening and closing, the upstream side immediately before the electromagnetic valve 242 A water system model in which the most downstream side of the point B, the pipe 241 is an open end (nozzle open) a 243 can be obtained.

When the water flow flowing in the pipe 241 is suddenly opened or closed by the electromagnetic valve 242 and the speed of the water flow is suddenly changed, a dense wave is generated in the water flow, and the water pressure in the pipe 241 is abnormally high. There are times when shock waves are generated.
Since the speed at which the dense wave propagates through the pipe is as high as 1200 m / sec, the shock wave of the first 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 opened rapidly, and the water flow is made to flow in the downstream nozzle direction, the water pressure change at point A suddenly fully opens and becomes large as shown in FIG. When the water flow begins, the density of the water at the tip of the water flow increases, forming a positive shock wave with high water pressure and high energy.
Since the water flow continuously flows in the pipe 241 and the positive or negative (honey or coarse) shock wave propagates instantaneously, the phenomenon that the impact force is mitigated by the interference of the accumulator 214 is also the electromagnetic valve 242. It is thought that it is transmitted to the whole water system from when the is turned on / off.
Therefore, when the valve is turned ON, the shock wave of positive pressure generated at the point A is suppressed in the direction of roughening the impact pressure by the interference phenomenon of the accumulator 214, and the impact force represented by a in FIG. The shock wave is suppressed and discharged from the discharge nozzle as a water flow.

At that time, on the point B side upstream of the electromagnetic valve 242, the water flow is pulled to the point A side, and water and water are separated to generate a shock wave in the negative pressure direction in which the density is low (coarse). When passing through the accumulator 214, the energy of the opposite positive pressure is added, and the shock wave is reduced in impact and propagates upstream. However, the shock wave propagated upstream is not discharged from the downstream nozzle.
The phenomenon effect that the impact force is reduced at the above points A and B occurs almost simultaneously because the water flow is connected, and when the shock wave passes through the accumulator 214, it becomes a shock wave in which the impact force is suppressed at each point. .
On the other hand, when the electromagnetic valve 242 is turned off and the valve is suddenly closed while the water flow is flowing in the pipe 241, as shown in FIG. 39b, in the water system of the second embodiment of the previous application and the present application, Since the discharge nozzle 243 is an open end, when the solenoid valve 242 is closed, the water flow supplied downstream from the solenoid valve 242 is eliminated, so that the water flow is supplied to the nozzle 243 as shown in FIG. Not. Therefore, the water flow is not discharged locally 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 turned OFF, the water flow that has flowed is pushed to the valve due to the inertia of the water, and the density increases to about twice, as shown in FIG. As shown by b, even if the accumulator 214 is used, a reflected wave having a fairly strong positive pressure is generated. However, the high-density reflected wave becomes a shock wave toward the upstream accumulator 214 in the water pipe, energy is absorbed by the accumulator 214 with time, and the shock wave ends.

When the accumulator 214 receives a sudden change in pressure from the outside, the rubber bladder sphere filled with gas reacts against the external force, so it absorbs energy and has a high positive pressure (honey wave). , And acts as a buffer that relaxes the change to a small degree against a transient phenomenon in which the pressure changes sharply.

Therefore, in the previous application and the second embodiment of the present application, the shock wave that gives a shock to the human body is ejected from the nozzle 41 when the pulse of the pulse water flow generator 38 is turned on and the water flow begins to flow and rises. In this case, a pulsed cleaning water discharge including a shock wave whose impact force is suppressed by the accumulator 214 shown in FIG. 38a at the time of rising is discharged toward the human body.
As for 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, when the toilet user feels uncomfortable butt cleaning discharge force, the output of the gear pump 30 can be adjusted remotely, and the water pressure and flow rate of the supply water gear pump 30 can be reduced. It can reduce the strength of the maximum pressure of the shock wave and is effective in reducing the feeling of impact.

In FIG. 40, a discharge having an impact water pressure waveform in which the impact force is suppressed at the start-up time of each pulse of the pulse water flow generator 38, showing an enlarged change in the pressure of the discharge water discharged in the buttocks cleaning process. Water will be discharged from the nozzle.
There is a pulse flow with the rise of the water flow at the time of ON 6 times in one “butt wash” command, and the butt is discharged with the discharge water with the shock wave hydraulic waveform with suppressed impact force in a short time of rise. Will be washed.
Even if the shock wave has a reduced impact force, it is higher than the water pressure P of the supply water gear pump 30, so the cleaning power is still high, and it can be used as a discharge cleaning water stream that cleans even inside the anal fold.

However, in the previous application and the second embodiment of the present application, it is needless to say that the water flow for cleaning the hips is not only the shock wave component, but cleaning is performed during the pulse ON period.
In FIG. 7 of the previous application, the “butt cleaning” discharge water pressure intensity shown in FIG. 40 is simply expressed as a substantially rectangular waveform.
FIG. 35 shows a detailed view of the water-based pressure reducing valve 215 and accumulator 214 used in the previous application and the second embodiment of the present application.

Next, the waste disposal apparatus according to the previous application has the following industrial problems, and it has been solved as the waste disposal apparatus of the second embodiment by making improvements in the second embodiment of the present application. explain.
That is, the waste disposal apparatus of the previous application has the following industrial problems.
As shown in FIGS. 1-3, since the crushing blade 14 is attached to the front-end | tip part of the long crushing rotary body 13 to the rotating shaft 20 of the electric motor 11, since a rotational moment is large, a dirt and the crushing blade 14 collide. Thus, the amount of work applied to the electric motor 11 when crushing filth 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 electric motor 11, the auxiliary airfoil 21 is required to produce clean air for forced air cooling by separating the gas / liquid in the cyclone device 18 and sending it to the electric motor 11. In addition, the cyclone device 18 must be installed in the waste disposal device 49, and the toilet system device becomes large and expensive.

In order to solve the above-described industrial problems, the following device has been made in the waste disposal apparatus of the second embodiment of the present application.
First, in order to reduce the load applied to the electric motor 11, the filth is made into a small filth lump in advance with the coarse pulverizing plate 205, and the rotary shaft 20 of the electric motor 11 is not used without using the long pulverizing rotating body 13. The pulverizing blade 14 is directly attached to the pulverizing blade 14 so that the pulverizing blade 14 has a small rotational radius to reduce the rotational moment and work amount at the time of pulverization. Second, a simple structure without using a large cyclone device 18 is used. The gas / liquid separation was carried out with a small waste disposal device.
Thirdly, the propeller fan 203 having a strong suction force can be used, and in another embodiment, the propeller fan 203 is improved to a small waste disposal apparatus using the sirocco fan 12 which is quiet and has a high space utilization rate.
Fourth, the electromagnetic discharge valve 211 was used as a part of the wall of the filth pulverization tank 208, and the electromagnetic discharge valve 211 was closed during decompression to ensure a negative pressure in the decompression chamber 202.
Fifth, in the standing urination process, we developed a process for urinating in the suction airflow to prevent the urine from splashing around the toilet and part of the urine from being scattered and scattered. Prevented hygiene.

The detailed description of the waste disposal apparatus 49 of the second embodiment and other embodiments of the present application will be given below.
The configuration of the waste disposal apparatus 49 of the second embodiment is composed of a decompression chamber 202 and a waste discharge chamber 210, as shown in FIGS.
The decompression chamber 202 has a waste introduction section 204 for introducing waste from the toilet 48 to the waste disposal apparatus 49, and a gas / liquid separation section 206 at the lower end of the waste introduction section 204. The decompression chamber 202 has a rotation of the electric motor 11. A suction means for the propeller fan 203 or the sirocco fan 12 is attached to the shaft 20, and a filth pulverizing blade 14 is attached to the tip of the rotary shaft 20, which rotates in a filth pulverization tank 208 at the bottom of the decompression chamber 202. Then, it has the structure which grinds filth.
In the second embodiment and the other embodiments, the decompression chamber 202 and the filth discharge chamber 210 are connected by a partition wall 201, and a discharge airflow that has cooled the streaky radiating fins 216 is formed on the upper portion of the partition wall 201. The sewage water discharge port 212 is provided at the lower part of the partition wall 201 and the electromagnetic discharge valve 211 is connected to the sewage water discharge port 212. When the electromagnetic discharge valve 211 is opened, The structure and configuration are such that filth water flows from the filth pulverization tank 208 below the decompression chamber 202 through the filth discharge chamber 210 to the sewage pipe 26 along the inclined path and is transferred to the sewage pipe 26.

The first problem to be solved in the second embodiment of the present application is to reduce the load of grinding.
25 and 26 using a propeller fan, and FIG. 27 using a sirocco fan as another example, when defecation feces are introduced and dropped from the filth introduction unit 204 to the filth treatment apparatus 49 The sludge is made to collide with the coarse crushing plate 205 to make a small lump of litter, 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, coarse pulverization was performed in advance so that a large load during pulverization was not applied to the electric motor 11.

A short 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 rotated in a filth crushing tank 208 to collide with the above-mentioned small filth litter. Is pulverized to reduce the rotational moment.
The odor prevention structure 69 at the lower part of the toilet bowl can only store a certain amount of water. However, if more water flows from the toilet bowl, it flows into the filth pulverization tank 208 of the filth disposal device 49 and is stored. When the lump flows into the crushing tank 208, there is already a lot of water in the waste crushing tank 208.

Next, the waste introduction part 204 and the coarse pulverization plate 205 of the waste treatment apparatus 49 will be described.
The filth introduction part 204 of the decompression chamber 202 is airtightly connected to the filth discharge port 9 at the lower part of the filth reservoir 8 of the toilet bowl, and is stored in the odor prevention structure 69 at the lower part of the filth reservoir 8 of the toilet bowl together with the washing water. The filth is decompressed by the rotation of the suction means so that the pressure reducing chamber 202 exceeds the thickness of the water layer of the odor control structure 69, and if the negative pressure is reached, the water layer of the odor control structure 69 is broken and the atmospheric pressure is increased. The filth falls together with the cleaning water and air into the filth introduction unit 204 of the filth treatment apparatus 49 by a suction airflow.
As shown in FIGS. 25 to 27, a plurality of coarse pulverization plates 205 are attached to the inside of the filth introduction unit 204, and a large filth litter after defecation collides with the coarse pulverization plate 205 when it falls downward together with the washing water. And it breaks into a little tiny litter. The filth lump and the washing water hit the sliding plate 207 which is inclined downward at the lowermost part of the filth introducing portion 204, slides down the surface of the sliding plate 207 and falls into the filth pulverization tank 208.

The second problem to be solved by the second embodiment will be described as to a structure capable of obtaining a gas / liquid separation action with a simple structure.
As shown in FIGS. 25 to 27, the suction airflow is sucked through the filth introduction part 204 of the filth treatment apparatus 49. Since the air is sucked by the rotation of the suction means installed in the upper part of the decompression chamber 202, the suction airflow is redirected to the U-shape at the tip of the lower part of the filth introduction part 204 and sucked up.
When the direction in which the suction airflow flows is suddenly bent at the tip of the filth introduction unit 204, the filth component and the washing water component mixed in the suction airflow are shaken off by the centrifugal force, similarly to when the cyclone device 18 is used. A gas / liquid separation phenomenon occurs in which air separates from filth and washing water.
Therefore, the air / liquid separated suction airflow is a clean airflow in which no filth component is mixed.
Since the gas / liquid separation is performed after finely pulverizing the filth in the filth crushing groove 16 of the previous application, it is difficult to separate the fine solid matter unless the full-scale cyclone device 18 is used. In this embodiment and other embodiments, before the filth is finely pulverized, gas / liquid separation is performed at the stage of coarsely pulverizing the filth in a small size in advance. The gas / liquid separation unit 206 having a simple structure that is simply changed at the tip of the unit 204 can efficiently remove the filth and liquid components from the suction airflow, and is installed in the cyclone device 18 as in the embodiment of the previous application. The air take-out pipe 22 and the auxiliary wing 21 are not necessary. The air flow can be a clean air flow used for cooling the electric motor 11.
The air strongly bent and sucked by the suction means by bending the gas / liquid separation section 206 of the filth introduction section 204 becomes an ascending air current, collides with the rotary blades (203 and 219) of the suction means, and air molecules at an angle of the rotary blade. Receives a force to be pushed out and becomes a discharge airflow.
As described above, the air / liquid separation unit 206 having a simple structure can efficiently remove the filth component and the liquid component from the suction air flow and can take out the clean air flow without using the large and expensive cyclone device 18. Therefore, the waste disposal device can be made small.

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

That is, first, an example in which the propeller fan 203 is used will be described below.
The propeller fan 203 is a low-priced suction means that strongly pushes a straight air flow in the direction of the rotary shaft 20 and has a strong exhaust force.
For this reason, the propeller fan 203 is not optimal for use in bending the airflow 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 FIGS. 25, 26, 28, and 29, the streaky radiating fins 216 are provided at positions where the propeller fan 203 receives the straight exhaust airflow at right angles. Therefore, the air flow was bent at a right angle to flow toward the waste discharge chamber. As a result, the propeller fan 203 with straight exhaust air can be used.
In the example 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 The electric wire 11 collides with the linear radiating fin 216 provided with the motor 11, performs heat exchange on the surface of the linear radiating fin 216, and cools the generated electric motor 11.
The stripe-shaped heat radiation fins 216 are formed with a plurality of lines of fins arranged in a line to increase the surface area in order to efficiently exchange heat on the surface.
The exhaust airflow generated by the rotation of the suction means is received by the streaky radiation fins 216, and the streaky fins are installed so that the exhaust airflow can escape from the openings 218 of the filth discharge chamber 210. It flows along the streaks of the radiating fins 216 and enters the waste discharge chamber 210 through the opening 218 provided in the upper part of the partition wall 201.

27, 30-a to c, and 31-a to c are assembly diagrams of examples using the sirocco fan 12, and the semi-cylindrical rotor blades 219 of the sirocco fan 12 are used. The electric motor 11 having the heat radiation fins 222 attached in close contact with the support 225 is installed in the space inside the fan, and heat is exchanged by the heat radiation fins 222 in the suction airflow of the sirocco fan 12 to Since the motor 11 is cooled efficiently, the space utilization rate of the waste disposal device 49 can be improved.
A structure in which the support ring of the radiating fins 222 in which a large number of plate-like fins are arranged in a radial shape is attached 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 blade 219 rotates to generate a suction airflow, the suction airflow cools the electric motor 11 and the heat radiating fins 222 and rises, and passes through the opening 218 provided in the upper part of the partition wall 201 to discharge the filth discharge chamber 210. to go into.
As shown in FIGS. 27, 30-a to c, and 31-a to c, the electric motor 11 that rotates the sirocco fan 12 is attached to a support 225 fixed to the wall of the decompression chamber 202 to form a semicylindrical shape. The electric motor 11 and the radiating fins 222 are attached to the inside of the sirocco fan rotor 219 so that there is no problem even if the sirocco fan rotor 219 rotates.
This structure is in the narrow decompression chamber 202 of the waste disposal apparatus 49 and has a very high space utilization rate.

The fourth problem of the second embodiment is the filth crushing tank 208 and the electromagnetic discharge valve 211, which will be described below.
When the first stage suction drying process is started, the electric motor 11 starts rotating, and when suction drying starts by the rotation of the suction means, the sewage that has slipped into the filth crushing tank 208 is moved to the rear of the front toilet user. The washing water and the discharge water used in the defecation assist process have already accumulated in the crushing tank 208. Further, the washing water used in the butt washing after the defecation is added to rotate the electric motor 11 in the crushing tank 208. The crushing blade 14 rotating at high speed with force and the small filth lump are collided and cut, and are crushed into fine filth particles, resulting in filthy water in which cleaning water and air are mixed and stirred.
At this time, the large debris lump that has been defecation is crushed into a small filth lump in advance by colliding with the coarse pulverization plate 205 in the filth introduction unit 204, and thus pulverized by many collisions with the rotating crushing blade 14. However, only a small work load is applied to the electric motor 11.
The grinding blade 14 is a knife edge and is made of a hard metal such as phosphor bronze material or stainless steel material. The crushing blade 14 rotates horizontally to slice and cut the litter mass. The crushing blade 14 collides with dirt many times, but the length of the crushing blade 14 is designed to be a small turning radius so as not to have a large rotational moment. Is small. Further, the sound of draining is reduced by rotating the crushing blade 14 horizontally.
The bottom of the filth crushing tank 208 may be V-shaped so that the crushing blade 14 can rotate and easily collide with the filth lump. However, consideration must be given to structures that facilitate the discharge of filth water.

The fifth problem of the second embodiment is that when creating a negative pressure in the decompression chamber 202, the decompression chamber 202, the filth discharge chamber 210, That is, the electromagnetic discharge valve 211 is installed at the filth water discharge port 212 of the partition wall 201.
This structure is the structure of the waste disposal apparatus 49 of the second embodiment shown in FIGS. 25 to 27 and the other embodiments. 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 sewage pipe side flows back to the filth discharge chamber 210 through the filth water discharge port 212 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 filth water discharge port 212 of the partition wall 201 to create a negative pressure in the decompression chamber 203, suction urination, suction stimulation, In the suction drying process, the backflow of air from the sewage pipe 26 can be prevented by closing the electromagnetic discharge valve 211 and rotating the suction means.

However, by providing the electromagnetic discharge valve 211 in the partition wall 201, in order to discharge the filth water from the filth crushing tank 208 to the sewer pipe 26, the electromagnetic actuator 209 of the electromagnetic discharge valve 211 is turned on and the valve is opened. Thus, the filth water is taken out and discharged to the sewer pipe 26.
When discharging the waste water from the waste crushing tank 208 to the sewage pipe 26, the electromagnetic discharge valve 211 can be opened only by opening the electromagnetic discharge valve 211. Before opening, it is necessary to make the atmospheric pressure upstream and downstream of the electromagnetic discharge valve 211 equal.
This is because if the air pressure is different between upstream and downstream of the electromagnetic discharge valve 211, air flows between the decompression chamber 202 and the sewage pipe 26, and the filth water flows in the direction of the sewage pipe 26 for a short time along the downward slope of the bottom. This is because it may not flow well.

As shown in FIG. 25, FIG. 26, and FIG. 27, the valve portion of the electromagnetic discharge valve 211 in a closed state is a part of the wall of the filth pulverization tank 208, and the opening of the electromagnetic discharge valve 211 is filth crushed. If the sewage water discharge port 212 including the bottom of the tank 208 is closed so that the electromagnetic discharge valve 211 is opened, most or all of the sewage water in the sewage crushing tank 208 flows out to the bottom of the sewage discharge chamber 210. Thus, the flow of filth water is designed so that there is almost no obstacle on the way, and it flows into the filth water discharge pipe 213 inclined downward in the direction of the sewer pipe 26.
Since the filth is pulverized into fine filth particles, has moisture, and has a lubricating effect, the structure as a solenoid valve can be operated without any hindrance and can be opened and closed.
If the electromagnetic discharge valve 211 is a liquid electromagnetic valve having a diameter of about 20 mm or more, waste water can be discharged in a short time.
As a type of the electromagnetic discharge valve 211, an electromagnetic valve such as a ball valve, a butterfly valve, a slide gate valve, or a flange valve can be used.
In FIG. 25, FIG. 26, and FIG. 27, the example using a slide gate valve was shown.
25, FIG. 26, and FIG. 27 show examples in which the electromagnetic actuator 209 of the electromagnetic discharge valve 211 is installed inside the filth discharge chamber 210, but it is also easy to install it outside the filth discharge chamber 210.

The discharged airflow that has entered the filth discharge chamber 210 enters the filth water discharge pipe 213 installed in the lower part of the filth discharge chamber 210, and the filth water in the filth water discharge pipe 213 is moved down and down the filth water discharge pipe 213. Then, it is swept away by the flow of the discharged air stream and transferred to the sewer pipe 26. The exhaust airflow is also discharged to the sewer pipe 26.
Further, the electromagnetic discharge valve 211 is closed when the power supply is OFF, and the waste is introduced into the waste crushing tank 208 and the crushing blade 14 attached to the tip of the rotary shaft 20 of the electric motor 11. During pulverization of the filth lump by rotation, negative pressure is created in the decompression chamber 202, and in the suction urine, suction stimulation, suction drying, and post-cleaning processes, the electromagnetic discharge valve 211 is opened according to an appropriate sequence, Or it is closed.

Only when the filth water is discharged to the sewer pipe 26, the rotation of the suction means is stopped and air is introduced from the toilet side and the sewage pipe side, and the upstream and downstream of the electromagnetic discharge valve 211 are equal to the atmospheric pressure as described above. Or, when the pressure is almost equal, the power of the electromagnetic discharge valve 211 is turned on, the valve body is opened, and the filth water passes through the filth discharge chamber 210 from the filth pulverization tank 208 toward the sewer pipe 26, Naturally flows into the sewer pipe 26. Thereafter, when the suction means is rotated in the post-cleaning process and the discharged air stream is sent to the filth discharge chamber 210, the sewage water is pushed to the sewer pipe 26 by the flow of the air flow. The filth flow path can be washed away with fresh washing water, and the valve body of the electromagnetic discharge valve 211 can be moistened.

A sixth problem of the toilet system using the waste disposal apparatus according to the second embodiment and the other embodiments is to prevent urine water from being scattered around the toilet in the standing urination process.
When pissing in a standing position, the urine water released from the urine draws a parabola and falls to the odor-preventing water surface 250 of the filth reservoir 8, and the sewage jumps on the surface of the water. There is also urine that partially spreads out in a conical shape and falls around the toilet bowl. The toilet bowl is contaminated with urine water or bounce water.
The toilet odor preventing structure 69 of the second and other embodiments of the present application uses the structure shown in FIG.
When the suction means is rotated and the decompression chamber 202 is set to a negative pressure, most of the water layer that serves as a odor stoper is sucked and dropped into the crushing tank 208. If the suction means continues to rotate even during urination, urine water will not accumulate in the odor stop structure 69 and will not rebound.
Since the outside air is continuously sucked from the toilet filth reservoir 8, the suction air current does not suck the urine droplets into the pulverizing tank 208 and scatter it outside the toilet bowl.
That is, as shown in the standing urination process sequence of the present application in FIG. 44, if the suction means continues to rotate until the urination is completed from the start of urination, the urine spreads in a conical shape and scatters. A part of the water can be prevented from contaminating the toilet area.
In addition, when the odor preventing structure 69 is rotated and the odor preventing water layer is sucked into the filth crushing tank 208, the water in the odor preventing structure 69 is completely invisible when viewed from the upper part of the filth reservoir 8. If the odor prevention structure 69 is designed, it is more effective in preventing the bounce back completely.
In order to prevent unsanitary surroundings of the toilet in the standing urination process, as shown in the sequence of FIG. 42, it is detected that the toilet room is entered and the toilet seat 3 is not seated. The limit switch (not shown) installed in the toilet seat bearing 4 of the toilet seat turns ON, and the microcomputer determines that it 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 outside air from the toilet sewage reservoir 8, the urination is finished, the urination is finished, and when the toilet seat 3 is lowered to the original upper toilet position, the toilet seat bearing 4 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. 42 to FIG. 42 in the process, the defecation assist process, the suction drying process, the hot air drying process, the process of sucking filth and dropping it into the crushing tank, the filth pulverization process, the discharge process of filth water into the sewer pipe, and the pre / post-cleaning process Some changes are required as indicated at 50.

First of all, since this application is a water-saving toilet system, for the toilet surface contamination, if the defecation act is performed with the toilet surface dry, filth may stick to the toilet surface, In order to prevent that it may be difficult to wash away easily in a later process, the “pre-cleaning” process shown in FIG. 43 is performed, and the fourth solenoid valve is previously placed on the toilet surface before the toilet process is started. 63 is opened, and about 1 L of washing water is poured from the toilet water pipe or pipe and wetted.
When a user enters the toilet room, a toilet water pipe or pipe is provided so that the washing water spreads from the upper part around the toilet bowl to the inner surface of the toilet bowl.
In addition, when the human sensor detects that the user has exited the toilet room after the entire toilet process is completed, as in the “post-cleaning” process, the cleaning water is placed on the inner surface of the toilet bowl as described above. When the solenoid valve 63 is opened, about 3 L of washing water flows from the toilet water pipe or pipe, cleans the toilet surface, and at the same time, cleans the waste flow path of the waste disposal device 49, and lubricates the valve body of the electromagnetic discharge valve 211. Water is stored in the sewage crushing tank at a water level that can be maintained.

Next, the sequence of the toilet system using the waste disposal apparatus 49 according to the second embodiment and the other embodiments will be described by taking as an example a process of discharging waste water from the defecation by the defecation assist process to the sewer pipe 26. . Refer to the sequence of FIGS. 41 to 50 for details.
In the defecation assist sequence, “straight warm water” of standard condition washing in the bidet washing process shown in FIG. 45 and “pulse water washing” of butt washing in FIG. 47 are also applied to hot water stimulation of defecation assistance. After confirming whether these two processes are during bidet washing, ass washing, or being used in the defecation assist process, the method has been changed to incorporate the defecation assist warm water stimulation sequence.

In addition, as shown in the defecation assist process sequence of 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 possible to select “suction stimulation” from the beginning,
The electromagnetic discharge valve 211 of the waste disposal apparatus 49 is turned off to close the valve, and the electric motor 11 is turned on to rotate the propeller fan 203 or the sirocco fan 12 as a suction means to exhaust the air in the toilet waste storage 8. Thus, when the toilet user sits with both kneecaps 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 reservoir 8 is secured. Toilet users felt a negative pressure aspiration stimulus in the rectum and anus, raised their convenience, and improved the defecation assist process, which allows them to select a process that can perform defecation assistance. By making it possible to select a suction stimulus from the beginning without going through warm water stimulation, it is possible to enhance the stool of defecation without contact, which is also effective for people with illnesses such as scabs.

When the stool disposal apparatus 49 shown in FIG. 26 and FIG. 27 of the second embodiment and the other embodiments is used, the toilet seat and the toilet are structured, and both the kneecaps are seated on the toilet seat. As shown in FIG. 33, since the space created by the thigh becomes a substantially airtight space, when the electric motor 11 rotates and the suction means sucks air at a high speed, the substantially airtight space is decompressed. You can feel negative pressure suction stimulation without touching the anus and rectum.
When gas in the region close to the anus of the rectum is sucked into the anus, the toilet user feels strong constipation and is encouraged to self-defecate. For those who do not have enough convenience, warm water stimulation and suction stimulation can be repeated any number of times. As described above, in the defecation assist process sequence of FIG. 46, when the convenience is enhanced by the above-described stimulation and the independent defecation is performed, the process proceeds to the buttocks washing process.

The hip cleaning process sequence shown in FIG. 47 is generated when the water flow is rapidly opened by sitting on the toilet seat in a relaxed posture and turning on the pulse water flow generator 38 as shown in FIG. The shock wave is a shock wave in which the impact force is suppressed by the interference of the accumulator 214, and the shock property is suppressed six times by one pulse water flow discharge command like the hot water discharge pulse flow shown in FIG. A pulsed hot water stream is discharged toward the anus, and the inside of the anal fold can be thoroughly washed. The ass washing can be repeated any number of times.
Of course, a person who feels a strong impact force can also adjust the discharge force of the gear pump 30.

Next, when proceeding to the first suction drying process shown in FIG. 48, it is confirmed that the power of the electromagnetic discharge valve 211 is OFF. If it is ON, the power is turned OFF and the valve is closed. When the motor 11 is turned on, the decompression chamber 202 is set to a negative pressure, the air in the toilet waste collection 8 is sucked, and as shown in FIG. An air flow is generated that is sucked into the toilet from between the thighs.
The suction airflow passes through the anus from the anterior region, reaches the fan of the suction means installed in the waste disposal device 49 from the waste discharge port 9 of the toilet, passes through the waste discharge chamber 210, and is discharged to the sewer pipe 26.
At this time, most of the moisture that wets the pubic area and anal area is in the form of water droplets adhering to or adsorbing to the pubic hair and skin, and if the pubic hair or skin shakes due to the flow of intense suction airflow, the water droplets are shaken off. And mechanically removed.

If the air pressure in the vacuum chamber 202 of the waste disposal device 49 becomes a negative pressure exceeding the differential pressure of the water layer thickness of the odor control structure 69 during the suction drying process, which is the first stage drying process, the odor control structure 69 The water layer is broken, and the filth and washing water in the toilet trash pool 8 are dropped into the filth introduction section 204. The large filth lump collides with the coarse crushing plate 205 to form a small lump filth lump together with the washing water and the sliding plate 207. And fall into the waste crushing tank 208.
In the waste 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 waste litter becomes waste water mixed with cleaning water and air.
Since toilet paper is not used in the present application, the crushing blade 14 can be used to turn the filth into filthy water with high fluidity in which fine particles are mixed.

In the water-saving toilet system of the present application, if the liquid component is too small in the pulverization tank 208 in the filth pulverization process, there is a possibility that the filth cannot be pulverized well. In order to avoid such troubles, a water level meter is installed in the crushing tank 208, and the crushing process starts only when there is a liquid component above a certain water level. It is also a good method to increase the liquid component to a certain water level by opening the electromagnetic valve 63 and pouring water into the crushing tank 208.
As shown in FIG. 48, the process of turning this filth into filth water is processed during the first stage of suction drying.

Next, the process proceeds to a warm air drying process, which is the second stage drying process shown in FIG. 49, and the hot air is blown out from the nozzle toward the local area to dry the moisture remaining on the skin surface with the warm air.
In order to prevent the foul odor of the filth reservoir 8 from rising on the face, simultaneously with the hot air discharge from the nozzle 57, simultaneously with the hot air discharge, the fan of the suction means is rotated at a low speed so that the speed is slightly lower than the hot air discharge speed. Air is sucked in by suction means.
When the second stage warm air drying process is completed and the electric motor 11 stops rotating, air flows from the toilet bowl and the sewage pipe into the decompression chamber 202 and the filth discharge chamber 210 becomes atmospheric pressure. When the valve 211 is opened, the filth water naturally flows out and flows toward the sewer pipe 26 along the inclination of the pipe, and the filth water discharge sequence shown in FIG. 50 is started.
When the toilet user feels that the local area has completely dried, the drying process issues an “end” command, gets up, arranges clothes, and exits the toilet room.
When the “end” command is issued and the user leaves the toilet room and the human sensor detects “exit”, the post-cleaning process shown in FIG. 43 is started.

The process sequence for discharging filth water in the second embodiment shown in FIG. 50 and other embodiments will be described. When the rotation of the electric motor 11 is automatically turned off, the atmosphere flows in from the toilet bowl and the sewage pipe side. Then, the decompression chamber 202 becomes the atmospheric pressure, the upstream and downstream of the electromagnetic discharge valve 211 become the equal pressure of the atmospheric pressure, and then the electromagnetic discharge valve 211 is opened, the filth water is at the bottom of the filth discharge chamber 210. It flows out along the downward slope, and most or all of the waste water is discharged to the sewer pipe 26.
The electromagnetic discharge valve 211 is automatically turned off and closed again in about 10 seconds, and the process of discharging waste is completed.

Next, when the toilet user leaves the toilet room and the human sensor detects the exit, the post-cleaning process sequence shown in FIG. 43 starts, the electric motor 11 is turned on for 5 seconds, and the suction means is rotated. The waste water in the sewage pipe 26 is discharged as a flow of air with the discharged air flow, the air in the toilet is replaced with fresh outside air, and the wash water is washed from the fourth solenoid valve 63 by the about 3 liters of post-wash water. To do.
A part of the washing water collects in the odor prevention structure 69 at the toilet outlet, so that bad odor from the waste disposal device 49 does not flow back into the toilet room.
Further, the remaining amount of the washing water for the post-cleaning flows into the waste disposal device 49 and flows to the pulverizing tank 208 to wet the valve body of the electromagnetic discharge valve 211 and to maintain the lubricity of the operation surface of the valve.

This is the end of the description of the toilet process sequence, but the warm water and warm air standby sequence is the same as in FIGS.

The present invention is not limited to the above-described embodiments, and various suction means and a high vacuum state operated by an aircraft can be easily obtained outside the toilet system without departing from the gist of the present invention. Of course, in the environment and the like, by replacing the suction means of the present application and the decompressed state of the decompression chamber, those skilled in the art can easily carry out the same invention object as the present application.

1. Assisting defecation using the suction toilet mechanism of the present application makes it easy to defecate, making it easier for elderly people with weak abdominal muscles and disabled people. It can also be installed in toilet systems that are used by an unspecified number of people, such as hospitals, nursing homes, highway service areas, train stations, airplanes, and other transportation facilities.
2. The possibility of pathogenic harmful bacteria spreading through the toilet has been fundamentally solved by eliminating the toilet operation of “wiping the hips”. The toilet system according to the present application is an effective countermeasure against infectious diseases in food service centers, food processing industries, hospital facilities, and the like. In addition, it is thought that it contributes to a society that is friendly to the elderly and disabled, and is widely accepted.
