Description

The present invention relates to a seat-type flush toilet system.

A conventional seat-type flush toilet is composed of a toilet that performs flush flushing to discharge feces, a device that performs a sanitary washing by taking a hot water shower on a local part of a human body, and an electrical switch thereof. A water faucet and hot air dryer necessary for hand-washing are provided in the toilet room or outside the toilet room.

It is normal for a toilet user when using such a conventional sitting-type flush toilet to perform the operations from the first stage to the twelfth stage shown below until entering the toilet room and going out of the room. is there.
1st stage Toilet user turns on the lighting switch in the toilet room to defecate or urinate, turns the door knob to open the door, and enters the room. Perform door lock.
2nd stage Open the toilet lid.
3rd stage Face in front of flush toilet. Then, in order to expose a part of the human body necessary for defecation or urination, a part of clothes is taken down.
Step 4: Sit back on the toilet seat in the flush toilet.
Step 5: Defecate or urinate.
6th stage Since a part of the excrement is attached to the part of the human body (anus, urinary organ and its surroundings) that has defecate or urinate, the toilet paper is cut out from the roll paper supply device and the anus or urinary organ is removed from the human body. Wipe with toilet paper using your fingers.
Seventh stage In a flush toilet equipped with a warm water shower, after defecation or urination, the anus and the vicinity of the urinary organ may be hygienically washed with a warm water shower and then wiped with toilet paper using fingers.
Step 8 Next, get up and arrange your clothes.
Before the 9th stage or the 8th stage operation, the flush flush knob is operated so as to discharge feces and urine in the toilet to the sewer pipe.
Step 10 Close the toilet lid.
Step 11 Move to the hand-washing position in the toilet room, operate the water tap to wash your hands, wipe with a handkerchief and dry. Release the door lock and open the door. Turn off toilet lighting.
Step 12 If there is no hand-washing equipment in the toilet room, open the door from the toilet room and wash the hands in the outside hand-washing equipment.
The above is a series of toilet operations conventionally performed by a toilet apparatus.

However, after stool or urination in the 5th or 6th stage, if you use your fingers to wipe the anus or urinary organs using toilet paper, some of the excrement or infectious harmful bacteria (norovirus) , Rotavirus, Salmonella, Escherichia coli, etc.) may be attached. In addition, in the seventh stage, even if hygiene cleaning is performed in a hot water shower, toilet paper that contains moisture is torn, or the toilet paper penetrates the toilet paper and is contaminated with traces of excrement or infectious harmful bacteria. There is a disadvantage that cannot be denied.

Furthermore, from the 6th stage to the 11th stage, until the fingers are washed, there is a trace amount on clothes touched with contaminated fingers, flush flush knobs, various toilet function electrical switches, hand-washing taps, toilet lids, toilet door knobs, door locks, etc. There is a hygiene problem that contaminates the excrement of infectious bacteria or infectious harmful bacteria.
As a result, infectious harmful bacteria are transmitted to other users through clothes and toilet equipment contaminated with infectious harmful bacteria, and in-house infections in homes, hospitals, schools, nursing homes, food companies, and lunch centers And cause food poisoning.

As an improvement measure, after defecation or urination, an apparatus has been developed that uses a roll paper to manually clean the area with a hot water shower without wiping it, and then dry the area with warm air. However, it takes more than 3 minutes to blow hot water over the local area for complete cleaning, and more than 5 minutes to dry the hot water washed area completely with hot air. I need time. Moreover, the present condition is that it is not marketed as a toilet apparatus so widely for the reason that it is not certain that it is completely clean. Eventually, it is normal to use the toilet paper to wipe off with the fingers in the series of toilet operations as described above.

National Institute of Infectious Diseases Information Center, April 10, 2012 “Group Food Poisoning Cases Detecting Norovirus in Workers' Clothing—Nagano Prefecture” http://www.nih.go.jp/niid/ja/norovirus- m / norovirus-iasrs / 1837-pr3871.html Food Analysis and Development Center, Shoji Tadashi “Why can't we prevent it? Norovirus food poisoning. Thinking from the case of outbreak” http://www.mac.or.jp/mail/140201/02.shtml

It is known from the above-mentioned non-patent literature that high-concentration pathogens are found in the feces and vomits of persons suffering from infectious harmful bacteria (Norovirus, rotavirus, Salmonella, Escherichia coli, etc.). When a person with an infectious harmful bacterium uses a conventional flush toilet and hand-washing equipment inside or outside the toilet, the hands and fingers contaminated with the infecting bacteria are wiped with various types of switches after the feces are wiped off with toilet paper. Cases from the Ministry of Health, Labor and Welfare and the National Institute of Infectious Diseases that were secondary contaminated via flush flush knobs, toilet seat lids, hand-washing faucets, common towels, door knobs, door locks, patient clothes, etc. Many reports have been made. Also, from the same research institution, how to deal with stool and vomitus contaminated with infectious bacteria such as norovirus, rotavirus, salmonella, etc., how to deal with it, human disinfection, disinfection of equipment, etc. in the official gazette What is published is well known.
In view of this fact, the present invention is proposed by considering that “there is a cause of the spread of infectious harmful bacteria in the toilet operation and toilet system when a conventional flush toilet is used”.

We devised a toilet system that rotated the toilet seat of the flush toilet toilet by θ degrees and turned the body toward the cleaning position F, and a non-contact automatic hand-washing device located at a distance L from the rotation center D of the rotary toilet seat .

The effect obtained by the present invention is that even when a finger is contaminated after stool, it is possible to wash the finger automatically and non-contact immediately after that, so that toilet tools, electrical switches, door knobs, clothes, etc. are completely contaminated with fingers. There is no touch. Hygienic toilet operation is possible, and as a result, the spread of infectious harmful bacteria through the toilet can be effectively prevented.

FIG. 1 shows a flush toilet system and a toilet room unit in which a seat-type flush toilet toilet 2 and a non-contact automatic hand washing apparatus 20 are installed at a distance L at an angle θ for realizing the object of the present invention.

The toilet operation in the toilet room using the seat-type flush toilet 2 and the non-contact automatic hand washing apparatus 20 according to the present invention will be described below with reference to FIGS.
First stage The toilet user turns on the toilet room lighting to defecate or urinate, and opens the toilet room door 16 to enter the room. Close the door lock.
Second stage The toilet lid 13 is opened.
3rd stage It turns backwards in front of the seat-type flush toilet 2. Then, lower body clothes are taken down to expose the body part necessary for defecation or urination.
Step 4: Sit back on the toilet seat in the flush toilet. (Reference position S)
Step 5: Defecate or urinate.
Step 6: Since some of the excreta is attached to the part of the human body that has defecates or urinated, the toilet paper is cut out from the toilet paper supply device 18, and the local area such as the anus or urinary organ is used as a toilet paper using the fingers. Wipe off.
Seventh stage In some cases, after the defecation or urination, the anus and the vicinity of the urinary organ are washed with the hot water shower nozzle 35 and then wiped with toilet paper using fingers.
Eighth stage Next, the toilet seat 5 is rotated by lightly kicking the toilet room floor 1 with a foot, and the body is rotated while sitting on the rotary toilet seat 5 up to the hand-washing device 20 at an angle θ that can be faced or hand-washed. (Washing position F)
9th stage When the hand is inserted from the hand insertion port 31 of the hand washing facility 20 at the washing position F, the infrared sensor 22 senses and the hand washing apparatus automatic sequencer 30 starts to operate, and the disinfecting soap liquid is discharged from the disinfecting soap liquid dispensing nozzle 23. Poured into. Hand wash with disinfecting soap solution. Next, after a certain period of time, the flowing water automatically flows out from the flowing water pouring nozzle 24 and the flowing water is washed by hand. Flowing water is stopped after a predetermined time, and then draining by the draining dry hot air 25 and hot air drying are performed, and the UV sterilization by the UV irradiation lamp 27 is turned on during the drying. When the hand is pulled out from the manual insertion slot 31, all cleaning sequences are completed.
10th stage When the fingers are cleaned, the toilet room floor 1 is again lightly kicked with the foot in the opposite direction to the 8th stage and the rotating toilet seat 5 is rotated to bring the rotating toilet seat 5 and the user's body to the reference position S. Turn around.
11th stage At the reference position S, the toilet user stands up, arranges clothes, presses the flush flush knob, and allows the filth to flow from the toilet to the sewer.
12th stage The toilet lid 13 is closed.
Step 13 The toilet user opens the door lock of the door 16 of the toilet room, turns the door knob 17 open, and then exits. Turn off the light.
As described above, the user can perform the cleaning process in a non-contact automatic manner by simply inserting his / her hand into the hand-washing device 20 immediately after finishing the toilet.

In the schematic view of the present invention shown in FIG. 1, the flush toilet user sits on the rotary toilet seat 5 and faces the body during the fourth to seventh stages and the tenth to eleventh stages of the toilet operation. The same direction (reference position S) and the direction (wash position F) in which the body is sitting on the rotary toilet seat 5 from the eighth stage to the ninth stage are shown in the same drawing.
That is, the flush toilet system for obtaining a sanitary toilet operation according to the present invention can be cleaned by inserting a toilet seat structure in which the rotating toilet seat 5 rotates θ degrees with a light force around the rotation center D and inserting a hand while sitting on the toilet seat. There is a feature that the non-contact automatic hand washing apparatus 20 is arranged at a distance L from the rotation center D.

Incidentally, the angle SDF at which the rotary toilet seat 5 rotates from the reference position S to the washing position F is θ degrees, and the rotation angle θ is preferably in the range of 10 degrees ≦ θ ≦ 90 degrees. Preferably, 30 degrees ≦ θ ≦ 70 degrees. Ideally, it is desirable to rub both hands directly against the hand-washing device 20 for washing.
When the rotation angle θ is small, the hand-washing device 20 is in front of the toilet, so that it is difficult to enter the toilet 2 in order to use the toilet, and it is difficult to rotate the body and take down clothes. On the other hand, if the hand-washing device is disposed at a position of 90 degrees or more, it is difficult to kick the foot and change the direction of the body.

The distance L is the distance from the rotation center D of the rotary toilet seat 5 to the drooping position 24 of the hand-washing water pouring water of the non-contact automatic hand washing apparatus 20. Although it depends on the physique of the toilet user, it is preferably in the range of 30 cm ≦ L ≦ 90 cm, preferably 40 cm ≦ L ≦ 50 cm. If the distance L to the hand-washing device 20 is too close, it is too narrow to sit on the toilet bowl 2, and if the distance L is long, the upper body must be laid out while sitting on the rotating toilet seat 5, and the hand-washing operation is extremely It becomes difficult to do.

The non-contact automatic hand washing apparatus 20 turns on / off the disinfecting soap solution and the washing water flowing out / stopping water, draining warm air drying and ultraviolet irradiation without touching the switch with any hand or finger. The processing time condition setting is managed and controlled by the automatic sequencer 30.

The technical contents of the electronic sequencer, sensor, nozzle, and the like of the hand washing apparatus automatic sequencer 30 are not included in the scope of the present invention because they can be easily realized by a combination of existing techniques.

FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1, and is a diagram schematically illustrating a rotation mechanism of the seat-type flush toilet 2 and the rotating toilet seat 5. The toilet seat according to the present invention has a two-layer structure in which a base toilet seat 8 having a function of opening upward when performing male urination and a rotary toilet seat 5 on the upper surface thereof are combined.

FIG. 3 is a diagram for explaining a portion B in FIG. Due to the difference in the form of the bearing holder 10
The main parts of the toilet seat 8 and the rotating toilet seat 5 are described.

FIG. 3A is a plan view of the bearing holder 10 in which the bearing 9 is embedded. FIGS. 3-b1 and 3-b2 show a cross section taken along line CC of FIG. 3-a. When the b1 type bearing and holder are used, the bearing rails 11 and 12 are used on both the upper surface of the base toilet seat 8 and the lower surface of the rotating toilet seat 5 as shown in FIG. Rolling friction resistance can be reduced.

In a configuration in which about 2/3 of the bearing of FIG. 3B2 is embedded in the holder, the bearing rail 11 is only required on one side as shown in FIG. 3-C2.

If the material of the base toilet seat 8 and the rotating toilet seat 5 is a hard resin, the structure shown in FIGS. 3D1 and 3D2 can be formed by digging a groove where the bearing rolls instead of the rail. There is an advantage that assembly becomes easy.

Since the weight of the user sitting on the toilet seat is applied to the bearing 9, and a rotational force is applied, at least three bearings need to be evenly arranged on the rotation circumference in order to maintain stability. FIGS. 1 to 3 show an example in which bearing holders 10 each having a structure of three bearings 9 are provided at four locations on the circumference.

The bearing 9 shown in FIGS. 1 to 3 is an example in which a ball bearing is used for the basic explanation of the present invention, but an inner ring rotating cross roller ring bearing using a cylindrical bearing (THK catalog no. 382-3 product model number RB30035USP), it is highly accurate even under heavy loads, and smooth rotation is possible. Since these correspond to the form in which the bearing 9 and the bearing rails 11 and 12 of FIGS. 1 to 3 are integrated, they can be replaced. In addition, if resin bearings are used, they are characterized by light weight and low cost.

As shown in the sectional view of the toilet bowl in FIG. 2, the guard plate 6 installed along the inner diameter of the rotating toilet seat 5 is smaller than the inner diameter of the base toilet seat 8, deeper than the position of the base toilet seat 8, and further from the position of the upper toilet bowl 3. It has a structure that is deep or even extended. This serves to prevent the filth from scattering to the structurally complex bearing 9 and the like. In addition, the guard plate 6 has a structure in which a stopper ring 7 is screwed to the space between the lower surface of the base toilet seat 8 and the upper portion 3 of the toilet seat so that the rotating toilet seat 5 cannot be removed from the base toilet seat 8 in the vertical and horizontal directions. Therefore, it cannot be removed even if a force in the rotational direction is applied while sitting on the rotating toilet seat 5, and it cannot be removed even if the base toilet seat 7 is lifted during a male urination.

The rotation angle θ of the rotary toilet seat 5 can be rotated clockwise or counterclockwise from the reference position S. However, the toilet seat rotation angle θ necessary for toilet operation is determined by the positional relationship where the toilet 2 and the hand-washing device 20 are disposed.
That is, the hand-washing device 20 is disposed on the right or left side of the flush toilet 2 and needs to be disposed at an angle θ and a distance L of a washing position F where a hand can be inserted while sitting on the rotary toilet seat 5 and both hands can be washed with water. . The rotating toilet seat 5 is required to rotate to an angle that enables this toilet operation. Further, a stopper for preventing rotational shaking may be placed so that the toilet operation performed while sitting on the rotating toilet seat 5 at the reference position S and the cleaning position F is stabilized.

While sitting on the rotating toilet seat 5, the floor is lightly kicked with a foot in the direction of the hand-washing device 20, and the body is rotated in the direction to face the hand-washing device 20. When a hand is inserted from the hand insertion port (sitting position) 31 of the hand-washing device hood 34, the infrared sensor 22 detects and a washing sequence is started.
It is desirable that the hand-washing device hood 34 is made of a transparent resin and can be seen and confirmed from the outside.

As an example of the cleaning sequence, a disinfecting soap solution is poured from the disinfecting soap solution nozzle 23. The soap solution is washed for about 20 seconds by rubbing the fingers of both hands, and then, after a set time, washing water is poured from the running water pouring nozzle 24 into the hand and washing with running water is performed. Next, the warm air blows out from the draining and drying hot air outlet 25 to blow off most of the wet hands. Along with the warm air drying, the ultraviolet irradiation lamp 27 is turned on, and the fingers are irradiated with ultraviolet rays for sterilization. When the hand is removed from the hand-washing slot 31, the infrared sensor 22 senses and the washing sequence ends.
A series of hand washing processes are completed in the hand washing apparatus 20 in a non-contact automatic manner.

Further, a non-contact automatic hand-washing device 20 that can be used in common by a person washing hands while sitting on the rotary toilet seat 5 and a person washing hands while standing is shown in FIG. As described above, it is necessary to prepare two types of insertion ports for the hand, that is, the sitting position 31 and the standing position 32 and widen the opening.
Next, it is also necessary to dispose the disinfecting soap solution pouring nozzle 23 for hand washing, the flowing water pouring nozzle 24 and the draining and drying hot air blowing port 25 at a slightly higher position in accordance with the standing position.

Since liquids are poured downward from a high position, the rebound of the liquid that has fallen on the sink does not jump out of the wide insertion port 31, and the draining dry hot air blowing port 25 installed at a high position is wet. A slightly deeper sink is prepared so that water drops that have been drained and dried by the hand will surely flow into the drain pipe 21 of the sink, and at the same time, forced exhaust from the exhaust pipe 26 branched in the middle of the drain pipe 21 of the sink An air flow is formed in the washing space of the hand-washing device 20, and water droplets ride on the air flow and flow into the drain pipe 21.
Further, the branch exhaust pipe 26 may be designed with an exhaust amount that also serves as an exhaust function of the entire toilet room.

Conditions such as the timing, combination, length of processing time, and processing intensity of hand-washing washing sequence processing can be freely set using sequencer technology.

As described above, in the flush toilet system of the present invention, immediately after sitting on the rotary toilet seat 5 of the flush toilet, defecating and urinating, and wiping the local area with the hand using toilet paper, the flush toilet system of the present invention is hand-washed, dried and sterilized. Can be completed without any manual switch operation or contact with other devices.
In the toilet operation according to the present invention, the user stands up, arranges clothes, and touches the flush knob etc. to drain the feces and urine in the toilet to the sewer pipe after washing the fingers. Can be kept in.

Also, as an improved version of the device that operates the flushing knob, there is a method that electronically detects the presence or absence of a human body and turns on and off the solenoid valve to flow feces and urine in the toilet, and when the user stands up from the toilet seat There are also commercially available devices that turn on the switch and allow flushing water to flow. In addition, toilets have been developed in which the toilet seat and toilet seat lid automatically pops up and opens when a person approaches the toilet.
It goes without saying that a more sanitary toilet system can be obtained by actively incorporating these non-contact devices into the toilet system of the present invention.

The second embodiment of the seat-type flush toilet system of the present invention is the toilet room shown in FIG. Toilet room with flush toilet system with toilet seat 5 and non-contact automatic hand-washing device 20 built in advance at an appropriate angle L at an appropriate angle θ, and other facilities necessary for toilet facilities are installed in advance It is characterized by being in the form of a unit.

If the rotation angle θ and the distance L of the rotary toilet seat 5 are slightly adjustable from the reference value, the toilet room unit for facility use mainly used by adult humans and the toilet room unit for facility use used by many children are used. Can be used. It is likely to become a form that is more widely spread to society.

The integrated toilet unit includes a toilet room door 16, a wall and ceiling, a floor and a ventilation fan, a toilet paper supply device 18, a hot water shower nozzle 35 and a control device 19, and a flush flush knob for flowing washing water for discharging manure in the toilet. Or a flash cleaning lightning switch system, non-contact automatic hand washing device sequence (disinfection soap solution supply, hand washing running water, draining hot air drying, UV sterilization ON / OFF) control device 30 etc. are built in advance, as a toilet unit factory It is characterized by being a manufactured product.

Considering that the conventional flush toilet system also contributes to the spread of infectious harmful bacteria and the cause of large-scale nosocomial and institutional infections of mass food poisoning, it has the rotating toilet seat that is the present invention A toilet system consisting of a flush toilet and a non-contact automatic hand-washing device is capable of extremely hygienic toilet operation, especially in families with infants and the elderly, hospitals, schools, nursing homes, food companies, lunch centers, large public facilities If it is introduced in such cases, it seems that it can contribute to the prevention of mass infection. It is also a technology that brings about a revolutionary change in toilet culture and hopes that it will spread and contribute to the general public as soon as possible.

In the toilet operation according to the present invention, it is necessary for all the users to perform the toilet operation according to the present invention, and education and display instructions are required. However, if it is understood that the operation of the toilet according to the present invention is hygienic, it will spread widely and generally rapidly, and it has elements that can become a social standard for using the toilet hygienically.
