Description

The present invention relates to a flush toilet that can be installed and used at any place and can dispose of excrement filth without contaminating the surroundings.

In order to easily install or temporarily add toilets at nursing care sites, shelters in disaster areas, construction sites, campsites, event venues, etc., portable toilets, temporary toilets, etc. have been used. A simple toilet is used. In addition to the toilet bowl body and the like, the simple toilet has a configuration in which a storage container for temporarily storing excrement is provided at a position below the toilet bowl body so that it can be taken out freely. Then, in the simple toilet, when a certain amount of the excrement is accumulated in the storage container, the storage container is taken out and the excrement is discarded to dispose of the filth. However, the storage container in which the excrement is accumulated is very unsanitary, and when the storage container is taken out during filth treatment, a foul odor is emitted to the surroundings. There are problems that the transportation of the container is troublesome, care is taken not to spill the filth from the storage container at the time of transportation, and above all, bad odor and disgust are a burden on the person who disposes of the filth.

Regarding the above-mentioned simple toilet, for example, proposals as shown in Patent Documents 1 to 3 have been made.
The flush toilet described in Patent Document 1 includes a storage tank (storage container) for storing excrement, a pneumatic device for moving excrement, and an excrement receiving container (toilet bowl body) provided on the toilet seat. And are equipped in a series. The flush toilet has a function of washing the toilet body with water, and even if it is used for a plurality of excretion, the bad odor can be suppressed by keeping the toilet body clean. Further, the flush toilet is provided with a pneumatic device for moving excrement, and the storage container can be installed at a position away from the toilet body. Therefore, the foul odor around the toilet bowl body is suppressed, and by further increasing the capacity of the storage container, it is possible to store excrement for a plurality of times.
In the urine absorption coagulation package described in Patent Document 2, activated coconut shell activated carbon and a water-absorbing polymer are sealed in a bag made of water-soluble paper, and when used for urine, the bag is put into urine as it is. It absorbs and coagulates urine.
The assembly-type simple Western-style toilet described in Patent Document 3 is provided with a filth holding shelf at a predetermined height from the lower open end of a tubular body (toilet bowl body) having open ends at the top and bottom, and is placed on the filth holding shelf. A bag (storage container) was arranged, the opening of the bag (storage container) was placed over the upper open end of the tubular body (toilet bowl body), and filth was stored in the bag. After excretion, the filth was stored. The entire bag can be disposed of as it is. Further, Patent Document 3 discloses that a coagulant, a deodorant, an antibacterial agent, etc. are arranged in a bag in the assembled simple Western-style toilet bowl, and the coagulant can absorb urine or the like. It is said that water-absorbent resin, pulp, paper pieces, wood chips, sawdust, etc., which can be incinerated in the above, are preferable.

In the above-mentioned conventional simple toilet, the one of Patent Document 1 has not solved the problem that a foul odor is generated or the excrement is spilled when the excrement in the storage container is treated with filth. Regarding this, in order to solve the problem, it is conceivable to use the water-absorbent polymer or the like disclosed in Patent Documents 2 and 3, but still, no solution has been made for the solid stool. ..
In other words, when using a water-absorbent polymer, etc., use one package for each urination of an adult, or when processing stool, tear the bag of the package and put the treatment agent on the stool. It describes spraying and the like (Patent Document 2).
However, when a water-absorbent polymer or the like is applied to a flush toilet, a water-absorbent polymer or the like is placed in the storage container, but as it is, it was used to wash liquid urine or the toilet bowl body with water. Only the water is absorbed by the water-absorbent polymer or the like, and the stool remains in the storage container as it is. For stool in the storage container, it is possible to sprinkle water-absorbent polymer etc. from above one by one, but this method will increase the burden on the operator due to bad odor and disgust, let alone multiple times. If the excrement is sent into the storage container, the water-absorbent polymer must be put into the storage container each time it is used, which is very complicated.
That is, if only liquid urine is targeted, it is known that coagulating the urine with a water-absorbent resin is effective for treating filth. However, no suitable means has been proposed for the case where even solid stool is to be solidified by the water-absorbent resin. Furthermore, in the case of a flush type that is effective for keeping the toilet bowl clean, even the water used for flushing must be treated as filth, and a water-absorbent resin should be applied to the filth treatment of flush toilets. Was extremely difficult.
An object of the present invention is to make it possible to coagulate all excrement in a storage container for temporarily storing excrement in a flush toilet so that filth can be treated easily and hygienically. is there.

When the transfer means is a negative pressure suction method, the inner diameter of the discharge port 24 is specifically set to 20 mm or more and less than 30 mm. When the transfer means is other than the negative pressure suction method, the inner diameter of the discharge port 24 is preferably as large as possible, and specifically, it is set to 30 mm or more and less than 60 mm.

The water supply device 23 includes a water supply tank 23A for storing water for washing the toilet bowl main body 22, a water supply port (not shown) for pouring water into the toilet bowl main body 22, and a water supply port 23A to the water supply port. It is equipped with a water supply pump 23B and a water supply pipe 23C for feeding water.
The capacity of the water supply tank 23A is preferably 2 L or more and less than 20 L from the viewpoint that it can be washed with water a plurality of times and the toilet unit 11 can be easily moved without being heavy. In the present embodiment, as the water supply tank 23A, a polypropylene tank having a capacity of 5 L is detachably attached to the toilet unit 11.
When the operation switch for washing with water is pressed, the water supply device 23 operates the water supply pump 23B, sends water from the water supply tank 23A to the water supply port via the water supply pipe 23C, and sends the water from the water supply port. It has a function of supplying water into the toilet bowl main body 22. When the transfer means for transferring excrement or the like from the toilet unit 11 to the tank unit 12 is a negative pressure suction method described later, the amount of water supplied for washing with water is preferably 300 ml or more and 1000 ml or less. The amount of water supplied can be adjusted by the operating time of the water supply pump 23B. Specifically, in this embodiment, the amount of water supplied for washing with water is set to 500 ml. Further, in the present embodiment, 100 ml of water is supplied after washing with water as stored water for preventing dirt from sticking to the bottom of the toilet bowl main body 22.
In addition to the configuration including the water supply tank 23A and the like, the water supply device 23 uses water supply equipment such as water supply pipes, faucets, and faucets in a building or a house to connect the water supply equipment and the water supply port. It may be configured to send water to the water supply port by connecting with a pipe such as a branch pipe or a hose. However, since the toilet unit 11 can have the effect of increasing the degree of freedom regarding movement and installation location by providing the water supply tank 23A and the like, the water supply device 23 is configured to include the water supply tank 23A and the like. Is preferable.

Inside the base 21A of the outer frame 21, spaces for providing the crushing means are provided in the lower portion and the rear portion of the toilet bowl main body 22.
In the present embodiment, the crushing means is composed of a discharge pipe 25 formed by connecting a plurality of straight pipes 25A and a plurality of curved pipes 25B so that the straight pipes 25A and the curved pipes 25B are alternately arranged. Has been done.

The configuration of the discharge pipe 25 will be described in detail with reference to FIG.
A curved pipe 25B is connected to the discharge port 24 of the toilet bowl body 22 from below, and the portion is referred to as an introduction portion 251 in the discharge pipe 25.
A straight pipe 25A is connected to the end of the introduction portion 251 so as to extend in a substantially horizontal direction, and the portion is referred to as a lower horizontal pull portion 252 in the discharge pipe 25.
A straight pipe 25A is connected to the end of the lower horizontal pulling portion 252 via a curved pipe 25B (elbow) so as to extend upward, and the portion is referred to as an ascending portion 253 in the discharge pipe 25. ..
A straight pipe 25A is connected to the end of the rising portion 253 via a curved pipe 25B (elbow) so as to extend in a substantially horizontal direction, and the portion is designated as an upper horizontal pulling portion 254 in the discharge pipe 25. To.
A straight pipe 25A is connected to the end of the upper horizontal pulling portion 254 via a curved pipe 25B (elbow) so as to extend downward, and the portion is referred to as a descending portion 255 in the discharge pipe 25. ..
Further, the introduction portion 251 is set as the upstream end of the discharge pipe 25, and a straight pipe 25A extending in a substantially horizontal direction is arranged at the downstream end of the discharge pipe 25, and the portion is discharged in the discharge pipe 25. It is said to be part 256. Then, the drainage pipe line 13 is connected to the discharge part 256 of the discharge pipe 25 (see FIG. 1).

In the discharge pipe 25, between the introduction section 251 and the discharge section 256, there are only one lower horizontal pulling section 252, a rising section 253, an upper horizontal pulling section 254, and a plurality of lower horizontal pulling sections, respectively. It is provided over.
In addition, when the lower horizontal pulling portion 252, the rising portion 253, the upper horizontal pulling portion 254, and the lowering portion 255 are provided at only one place, the discharging portion 256 is a lowering portion via a curved pipe 25B (elbow). If it is connected to the end of 255, or if the lower horizontal pulling portion 252, the rising portion 253, the upper horizontal pulling portion 254, and the lowering portion 255 are provided at a plurality of locations, the lower horizontal pull portion 252, the ascending portion 25 It is connected to the end of the part or descent part.
When excrement or the like flows in the discharge pipe 25, the solid stool is discharged from the introduction portion 251 which is the upstream end to the downstream end in the discharge pipe 25 by liquid urine and water (sewage). It is swept away toward a certain discharge part 256. In the discharge pipe 25, the lower horizontal pulling portion 252 to the rising portion 253 descend from the sideways to the upward flow direction, the rising portion 253 to the upper horizontal pulling portion 254 from the upward to the lateral pulling direction, and the upper horizontal pulling portion 254 descending. In the portion 255, the flow direction changes significantly from the lateral direction to the downward flow direction a plurality of times when passing through each portion. Therefore, the solid stool is finely crushed by colliding with the inner surface of the discharge pipe 25, adding resistance due to a change in the flow direction, or applying an impact due to ascending or descending.
Further, as described above, the flow direction changes significantly and rapidly over a plurality of times, so that the flow state of the urine and the water (sewage) in the discharge pipe 25 becomes turbulent. Therefore, the crushed stool is stirred together with the urine and the water (sewage) in the discharge pipe 25 until it reaches the discharge section 256, and is mixed substantially uniformly. Therefore, when the stool, the urine, and the water (sewage) are crushed when sent from the discharge pipe 25 to the drain pipe 13, the stool and the water (sewage) are mixed substantially uniformly with excrement or the like in which all of them are liquefied. Will be done.
Here, when the transfer means for transferring excrement or the like from the toilet unit 11 to the tank unit 12 is a negative pressure suction method described later, the discharge pipe 25 has a lower horizontal pulling portion 252, an ascending portion 253, and the like. It is preferable that the inner diameters of the upper lateral pulling portion 254 and the lowering portion 255 are set to be smaller than the diameter of the human anus, that is, the thickness of the stool. When the inner diameters of the lower horizontal pulling portion 252, the rising portion 253, the upper horizontal pulling portion 254, and the lowering portion 255 are made smaller than the thickness of the stool, the stool is satisfactorily and preferably crushed in the discharge pipe 25. When the transfer means is a negative pressure suction method, the inner diameters of the lower horizontal pulling portion 252, the rising portion 253, the upper horizontal pulling portion 254, and the lowering portion 255 are specifically set to 20 mm or more and less than 30 mm.

In addition to the discharge pipe 25, the crushing means can also be realized with the following configuration.
That is, a temporary storage tank for temporarily storing excrement and the like (stool, urine and water (sewage)) discharged from the discharge port 24 of the toilet bowl main body 22 is provided in the toilet unit 11, and the temporary storage is also provided. Inside the tank, stirring blades for stirring temporarily stored excrement and the like are rotatably provided. Then, by rotating the stirring blade, the stool is crushed and stirred together with the urine and water (sewage) to make all liquefied excrement and the like. Further, it is also possible to construct a pressurized pressure feeding type transfer means described later by giving direction to the excrement or the like liquefied by the stirring blade and then flushing it into the drainage pipe line. ..

However, when the flow crushing method using the discharge pipe 25 and the storage crushing method using the stirring blades are compared, it is desirable to adopt the flow crushing method as the crushing means.
That is, in the above storage and crushing method, it is necessary to temporarily retain excrement and the like in the temporary storage tank, and a means for sealing off bad odors and the like from the temporary storage tank is required.
Further, in the storage crushing method, a power such as a motor is required to rotate the stirring blade. Furthermore, since solid stool has viscosity before crushing, the stool may stick to the stirring blades and cause clogging. Therefore, the power of the motor or the like is large and has high output. Is required.
In addition, the above storage and crushing method requires a temporary storage tank, and in addition to such a temporary storage tank, a toilet unit equipped with a large and high output motor or the like is large and very heavy.
Further, a large and very heavy toilet unit is forced to struggle even to move, and it may be necessary to reinforce the floor of the room in which the toilet unit is installed so as to bear the weight of the toilet unit. , The installation work of the toilet unit may become extremely complicated.

On the other hand, in the flow crushing method, only stool, urine and water (sewage) are flown in the discharge pipe 25, the stool is crushed, and the crushed stool, urine and water (sewage) are agitated. , No need for heavy mechanical elements such as motors and tanks for crushing the stool and stirring stool, urine and water (sewage).
Therefore, the configuration related to the crushing of stool can be simplified, and the weight of the toilet unit 11 can be reduced.
Therefore, the crushing means by the flow crushing method is more useful than the crushing means by the storage crushing method.

[Tank unit 12]
As shown in FIG. 1, the tank unit 12 has a storage container 31 for storing liquid excrement and the like sent from the toilet unit 11 via the drainage pipe line 13. Further, in addition to the storage container 31, the tank unit 12 has a transfer means for transferring the liquid excrement or the like from the toilet unit 11 to the storage container 31 via the drainage pipe line 13. doing.

The transport means will be described.
In the present embodiment, as the transfer means, the inside of the drainage pipe line 13 or the like is made a negative pressure, the liquefied excrement or the like is sucked, and the waste is transferred from the toilet unit 11 to the tank unit 12 (storage container 31). Uses a negative pressure suction method.
Here, in order to explain the negative pressure suction method, a negative pressure suction method when a negative pressure tank is used will be given as a specific example, but the configuration, means, method, etc. of the negative pressure suction method are described in the above drainage pipe line. If it is possible to create a negative pressure inside the 13 or the like, the pressure is not particularly limited. For example, a vacuum pump is directly connected to a part of the drainage pipe 13 or the storage container 31 to create a negative pressure inside. It may be.
The negative pressure tank 32 includes a tank body 32A, a vacuum pump 32B, and the like. The tank body 32A is made of a pressure-resistant container that can withstand a required vacuum pressure, and is provided with an atmosphere release valve 32C that opens the tank body 32A to the atmosphere. The vacuum pump 32B is connected to the tank body 32A via a pipe 32D provided with a pressure reducing valve for controlling the timing of evacuation, and by sucking air in the tank body 32A, the tank body 32B is sucked. The pressure of 32A is reduced. Further, the drainage pipe line 13 is connected to the tank body 32A to suck the liquid excrement or the like into the tank body 32A, and the liquid excrement or the like is discharged from the tank body 32A. A discharge port 32F is provided.

In the negative pressure tank 32, the inside of the tank body 32A is decompressed and then opened to the atmosphere, so that the inside of the drainage pipe 13 connected to the tank body 32A becomes a negative pressure due to the vacuum pressure. Suction power is generated.
By utilizing the suction force, excrement and the like can be discharged from the toilet body 22 of the toilet unit 11 by passing through the discharge port 24 and the discharge pipe 25 which is a crushing means. Then, the liquid excrement or the like is sent into the drainage pipe line 13, flows in the drainage pipe line 13, and flows from the drainage pipe line 13 through the suction port 32E to the negative pressure tank 32. Is drawn into the tank body 32A.
The liquid excrement or the like drawn into the tank body 32A is discharged into the storage container 31 when the discharge port 32F of the tank body 32A is opened.
That is, the negative pressure tank 32, which is the transfer means, is connected to the drainage pipe line 13 in the toilet unit 11 by making the inside of the drainage pipe line 13 connected to the negative pressure tank 32 negative pressure. A suction force to the discharge port 24 is generated in the excrement or the like in the toilet bowl main body 22 through the discharge pipe 25. Then, all of the excrement and the like sucked into the discharge port 24 become liquid when flowing in the discharge pipe 25, and the liquid excrement and the like are transferred from the toilet unit 11 to the storage container 31. It is transferred through the drainage pipe line 13 and the like.

The atmosphere release valve 32C and the pressure reducing valve provided in the negative pressure tank 32, or the valves provided in the suction port 32E and the discharge port 32F are each composed of a solenoid valve.
The tank unit 12 is provided with a control device (not shown) that electrically controls these solenoid valves.
Further, the control device is electrically connected to the water supply device 23. Then, the control device controls each solenoid valve based on the operation switch for washing with water in the water supply device 23.

In addition to the negative pressure suction method, the transfer means uses a pressurized pressure feeding method in which liquefied excrement or the like is pressurized and pumped from the toilet unit 11 to the tank unit 12 (storage container 31). It is also possible to adopt it.
As a specific example of the pressurized pressure feeding method, the toilet unit 11 is provided with rotary blades (for example, the stirring blades mentioned in the crushing means), and the liquid excrement or the like is pressurized by the rotary blades from the toilet unit 11. Examples thereof include a configuration in which pumping is performed to the storage container 31 via the drainage pipe line 13.

However, comparing the negative pressure suction method and the pressurized pressure feeding method, it is desirable to adopt the negative pressure suction method as the transfer means.
That is, in the pressurized pressure feeding method, in order to pump the liquid excrement or the like from the toilet unit on the upstream side to the storage container on the downstream side, it is necessary to pressurize the toilet unit on the upstream side. .. Therefore, it is necessary to provide the toilet unit with the rotary blade, a motor for rotating the rotary blade, a tank for storing excrement during pressurization, and the like, and the toilet unit is large. Since it becomes very heavy, the installation work of the toilet unit may become extremely complicated.
In addition, liquid excrement, etc. pressurized on the upstream side decreases the pressure for pumping as it moves toward the storage container on the downstream side, so there is a risk that residual material may be generated in the pipe during pumping. is there. In order to suppress the generation of such a residual amount, it is necessary to increase the amount of a large amount of liquid, that is, the amount of water for washing the toilet bowl body 22, and to flush the residual amount according to the amount of water.
However, if the amount of water to be pumped is increased, the water supply tank of the water supply device provided in the toilet unit also needs to be large and has a high capacity, so that the toilet unit becomes even larger and very heavy. .. In particular, as the amount of water pumped increases, the amount of excrement composed of stool and urine in the storage container 31 decreases. Further, since the drainage pipe line at the time when the pumping is stopped is filled with liquid excrement or the like, there is a possibility that the liquid excrement or the like may flow back from the drainage pipe line to the toilet unit.

On the other hand, the negative pressure suction method has a configuration in which liquid excrement or the like on the upstream side is sucked from the downstream side. Therefore, the negative pressure tank 32 can be arranged in the tank unit 12 on the downstream side, and it is not necessary to provide the negative pressure tank 32, which is a heavy object, in the toilet unit 11, and the toilet unit is made lightweight. It can be maintained, and the work related to the installation of the toilet unit 11 becomes easy.
Further, in the case of the negative pressure suction method, the suction force for liquid excrement and the like increases from the upstream side to the downstream side. Therefore, residual components are less likely to occur in the pipe, and the drainage pipe line 13 and the like can be kept clean.
Further, if the negative pressure suction method is used, a large amount of water is not required to flush out the residual portion in the pipe, and the amount of water used for washing with the toilet bowl main body 22 can be minimized. , It is possible to substantially improve the amount of excrement composed of stool and urine in the storage container 31.
Therefore, the transfer means by the negative pressure suction method is more useful than the transfer means by the pressure pressure feeding method.
When the inventor and others measured the amount of water used for one water washing by the pressurized pressure feeding method and the amount of water used for one water washing by the negative pressure suction method, the pressure and pressure feeding method was 5.5 L, negative. It was 500 mL by the pressure suction method. Assuming that the overall storage capacity of the storage container 31 is 10 L, in the pressurized pressure feeding method, excrement and the like in the storage container 31 must be treated with one use, but in the negative pressure suction method, there are a plurality of cases. It is possible to collect excrement and the like for each dose.

[Storage container 31]
The storage container 31 will be described.
As shown in FIG. 3, the storage container 31 is made of a plastic molded product formed in a bucket shape. The storage container 31 is arranged below the negative pressure tank 32 inside the tank unit 12, and receives liquid excrement or the like released from the tank body 32A of the negative pressure tank 32, and is inside the storage container 31. Store in.

Inside the storage container 31, a storage bag 33 for storing the liquid excrement and the like is detachably attached. Then, when treating the liquid excrement or the like stored inside the storage container 31 as filth, the work can be performed only by taking out the storage bag 33 from the storage container 31.
A non-permeable material is used for the storage bag 33. Here, the above-mentioned "impermeable" means not only the case where the liquid does not strictly permeate but also the case where the liquid does not substantially permeate.
Any suitable impermeable material is adopted as the material of the storage bag 33. Specific examples of the material include thermoplastic resin films such as polyethylene, polypropylene, polyamide, polyvinyl chloride, polyvinylidene chloride and polyester, and metal foils such as aluminum. Among these materials, a thermoplastic resin film is preferable because it can be easily bonded by heat fusion (heat sealing) and has good productivity.
When a thermoplastic resin film is used, the size, shape, thickness, etc. of the storage bag 33 are preferable because it is flexible, easily covers the inside of the storage container 31, and is less likely to be torn or leaked. , Polyvinylidene chloride and polyvinyl chloride are preferable because the odor does not easily leak. Further, in the present invention, since liquid excrement and the like are gelled by the treatment agent described later and the odor is suppressed, polyethylene is more preferable for the thermoplastic resin film in terms of low cost. The thickness of the storage bag 33 is preferably 0.01 to 0.05 mm, more preferably 0.02 to 0.04 mm. Further, the storage bag 33 is preferably colored opaquely such as black or blue rather than a colorless and transparent one.
The storage bag 33 may be provided with a function of closing the opening. Examples of the function include a mechanism for engaging and sealing the grooves, and a configuration with a string or tape for binding. Further, the storage bag 33 may be provided with a handle for easy removal and transportation, or may be provided with a rib shape or an adhesive coating for easy hooking on the edge of the storage container 31. Good.

In the storage container 31, the treatment agent 34 is arranged inside the storage bag 33. The treatment agent may be arranged as it is, but it is preferable that the treatment agent is fixed in the storage bag 33 by using a fixing means in order to prevent deviation and efficiently contact the excrement. As the fixing means, a sheet material made of a non-woven fabric or water-soluble paper sprinkled with the treatment agent, a film in which the treatment agent is fixed with a binder resin, or a package in which the treatment agent 34 is wrapped in a water-soluble package. Examples include packs.
As the treatment agent 34, one containing a water-absorbent resin is used. When liquid excrement or the like is stored in the storage container 31, when it comes into contact with the treatment agent 34, it is gelled and solidified to become a solid.
Then, the filth treatment can be performed simply and cleanly by taking out the solid waste and the like from the storage container 31 together with the storage bag 33 and disposing of it.

The water-absorbent resin contained in the treatment agent 34 is insoluble in water and has the property of gelling excrement by absorbing liquid components such as urine and water (sewage), that is, it absorbs liquid and swells. If it is a thing, it is not particularly limited. More preferably, the water-absorbent resin is inexpensive, has excellent water-absorbing properties such as safety, durability, water-absorbing ratio and water-absorbing speed, and is free from putrefaction.
Known water-absorbent resins can be used. Specific examples include cross-neutralized polyacrylic acid, neutralized starch-acrylic acid graft polymer, hydrolyzate of starch-acrylonitrile graft polymer, and saponified product of vinyl acetate-acrylic acid ester copolymer. Isobutylene-maleic anhydride copolymer crosslinked product, acrylonitrile copolymer or acrylamide copolymer hydrolyzate or crosslinked product thereof, acrylate-acrylamide copolymer crosslinked product, polyvinyl alcohol crosslinked product, modified polyethylene oxide crosslinked product, Examples thereof include a acrylamide-2-methylpropane sulfonate copolymer crosslinked product, a (meth) acryloyl alkane sulfonate copolymer crosslinked product, a crosslinked carboxymethyl cellulose salt, and a crosslinked polymer of a cationic monomer. Of these, the cross-linked polyacrylic acid partially neutralized product and the neutralized product of the starch-acrylic acid graft polymer have good water absorption and swelling characteristics, safety and economy, and also have a deodorizing effect. Therefore, it is particularly preferable as a water-absorbent resin for the above-mentioned treatment agent.

Further preferable water-absorbent resins include deodorant water-absorbent resins and antibacterial water-absorbent resins. When these deodorant water-absorbent resins and antibacterial water-absorbent resins are used, the deodorant effect is increased and antibacterial properties are imparted. Therefore, even if left for a long time, the generation of odor is further suppressed and the occurrence of putrefaction is prevented. be able to.
Examples of the deodorant water-absorbent resin and the antibacterial water-absorbent resin include those obtained by blending the above-mentioned water-absorbent resin with a quaternary ammonium salt, a quaternary pyridium salt, a quaternary phosphonium salt, a silver colloid, a zeolite, or the like. .. In the case of a quaternary salt, it is particularly preferable because the salt is exchanged with the carboxylic acid salt of the water-absorbent resin to improve the adhesion of the above salt to the water-absorbent resin.
The water-absorbent resins listed above may be used alone, or two or more of them may be appropriately mixed and used. The water-absorbent resin may be granulated into a predetermined shape, or may have various shapes such as amorphous crushed shape, spherical shape, scaly shape, fibrous shape, rod shape, lump shape, and powder shape. In order to improve the water absorption performance, it is more preferable that it is in the form of powder.

The water absorption ratio of the water-absorbent resin can be specified by JIS K7223-1996. Specifically, when 1.00 g of a water-absorbent resin is used with respect to a 0.9% by mass-concentration saline solution, the water absorption ratio is preferably 10 to 200 times by weight, more preferably 20 to 100 times. Is.
The water absorption rate of the water-absorbent resin can be specified by JIS K7224-1996. Specifically, when 2.00 g of a water-absorbent resin is used with respect to a 0.9% by mass-concentration saline solution, the water absorption rate is preferably 10 to 600 seconds, more preferably 15 to 200 seconds. ..
For applications such as disposable diapers, a water-absorbent resin having a high water absorption rate is preferred because it quickly absorbs urine released into the diaper. However, a substance having a high water absorption rate absorbs the touched water pinpointly at the moment of contact with the water, so that the water absorption force is not necessarily exerted on the entire excrement or the like stored in the storage container 31. As a result, there is a risk that the water absorption capacity cannot be fully exerted. Therefore, in the application of the present invention, it is not necessary to use a water-absorbing resin having a particularly high water absorption rate, and by selecting a water-absorbent resin having a slow water absorption rate, a large amount of liquid excrement or the like supplied over a plurality of times can be absorbed. It can absorb up to the limit of the water absorption capacity of the sex resin.

The particle size distribution of the water-absorbent resin particles is not particularly limited, but a volume-based median diameter of 100 to 1000 μm is preferable, and more preferably 200 to 800 μm. The particle size can be measured by various methods such as a laser diffraction type particle size distribution meter, a sieving method, and a Coulter counter. However, when using a laser diffraction type particle size distribution meter, if a general measurement method that disperses particles in water is adopted, the particles will absorb water and swell, so it is better to use a dry unit that measures while dropping powder. preferable. A more preferable particle size measuring method in the present invention is a sieving method using a standard sieve.

The treatment agent preferably contains 5 g or more of a water-absorbent resin. That is, the amount of the water-absorbent resin is appropriately set according to the storage amount of the storage container 31, but the storage amount of the storage container 31 does not have to be frequently treated with filth, and at the time of sewage treatment. From the viewpoint of suppressing the weight so as not to burden the work, 5 L to 20 L is preferable, and the amount corresponding to the stored amount is 5 g or more.
In addition to the water-absorbent resin, the treatment agent includes known deodorants (for example, zeolite, charcoal, etc.) and antibacterial agents (for example, quaternary ammonium salt, quaternary pyridinium salt, TPN, silver colloid, etc.). , Fragrances (eg, fragrances that smell like citrus, lavender, mint, etc.) and the like may be contained. In addition, these deodorants, antibacterial agents, and fragrances may be mixed with the water-absorbent resin, or may be contained by kneading into the water-absorbent resin.
