[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a particulate excrement treating material having a non-water-absorbing and smooth surface is a human and animal excrement treating material, and has a particle size of 10 mm to 6 mm or a particle size of 6 mm or less. Are formed into granular materials. In the present invention, the particulate excrement disposal material can be made of a material having corrosion resistance so that washing with water, a washing solution or the like can be performed stably. In the present invention, it is preferable that the shape of the non-water-absorbing particulate excrement disposal material has a smooth surface so that it can be easily washed with water or a washing solution, and the attached dirt can be easily separated. .

In the present invention, the granular excrement disposal material has at least one cross-section, such as a sphere, an ellipsoid or a cylinder, formed in a rotating body so that it can be easily moved by, for example, rolling. Preferably. In particular, a sphere or a sphere is preferable because it can roll in all directions.
The particle size of the granular excrement disposal material can be formed into a granular material having a particle size of 6 mm or less, similarly to the conventional animal excrement disposal material. As the granular material having such a particle size, for example, 6
Granules having a particle size of 2.5 mm to 2.5 mm, 2.5 mm to 1
It can be formed into a granular material having a particle size of 1 mm or a granular material having a particle size of 1 mm or less. However, before and after excretion, the cat is caught between cat's claws or adheres to the hair, so that it is easy to be taken out after excretion.
It is preferable that the particles have a particle size of 2.5 mm or more.

However, the water retention of the non-water-absorbing granular excrement disposal material increases as the particle size decreases, so
It is preferred that the particles have a small particle size of less than 1 mm. In this case, the lower limit of the particle size of the particulate excrement disposal material is set so that the washing water passes well during washing and drying, and the drying time is short. For example, a particle size of 1 mm to 0.3 mm, ie, a sphere on a 0.3 mm screen under a 1 mm sieve, or a particle size of 1 mm to 0.5 mm, ie, 1
It is preferred to use spheres on a 0.5 mm sieve under a mm sieve. As the granular excrement disposal material, for example, a glass sphere is preferable because it is easily available. When the granular excrement disposal material is a glass sphere, the particle size can be, for example, 1 mm to 0.3 mm, preferably 1 mm to 0.5 mm, and for example, 2.5 mm to 5.5 mm. it can.

However, for example, in the case of a granular material of a material having a large specific gravity, such as a stainless steel ball, particularly a sphere, it is difficult to adhere to a space between nails and hairs.
Spheres in the range of 1.5 mm to 1.5 mm can be used. Place a relatively large sphere or sphere so that it does not enter between the nails,
By placing relatively small spheres or spheres in the lower layer, it is possible to prevent water from entering between the cat's claws and increase water retention.

In the present invention, the granular excrement disposal material comprises 6
It can be formed into granules having a particle size in the range of 10 mm to 10 mm. As described above, the granular excrement disposal material having a particle size of 6 mm to 10 mm has a small water retention between particles, for example, in the case of a spherical surface having a smooth surface, as compared with particles having a smaller particle size. It is easy to separate and remove solid excrement such as feces adhering to the soil. As in the case of small particles of 6 mm or less, it is possible to clean in a short time by removing the portion where solid excrement is adhered such as feces, but it can be easily separated even if it is washed away with washing water. be able to.

In the case of a granular excrement treating material of 6 mm to 10 mm, the surface of the urine is smooth, and when the material has water repellency, the amount of the material adhered to the surface of the urine is reduced. The frequency of cleaning the granular excrement disposal material can be reduced, and the cleaning can be easily performed by one cleaning. In addition, the perforated plate member such as a net supporting the particulate excrement disposal material can have a large hole diameter, and is easier to clean than a small particulate excrement disposal material. In addition, it can be prevented from getting in between the cat's claws and sticking to the hair, and the surroundings can be less stained, which is hygienic.

In the present invention, a water-repellent agent, for example, a silane compound, silicone, paraffin, fluororesin or acrylic, is used on the surface of the granular excrement disposal material, for example, to make the glass surface water-repellent. Water repellency can be imparted to the surface of the granular excrement disposal material by applying a resin or other organic or inorganic waterproofing agent. By doing so, the amount of urine and the like adhering to the surface of the granular excrement disposal material can be reduced. In the present invention, the deodorant can be deodorized by using the particulate excrement disposal material and / or the sewage storage unit. As the deodorant, a commercially available deodorant can be used. In the present invention, the non-water-absorbing particulate excrement treating material is preferably formed of a corrosion-resistant material in order to be washed and used repeatedly, and
Since the particles come into contact with each other during use and wear due to friction is inevitable, it is further preferable that the particles have abrasion resistance.

In the present invention, the granular material can be formed of a material having corrosion resistance, for example, a plastic material, a glass material, a stainless steel material, or a ceramic material such as molten slag. This granular material can be manufactured using concrete waste, plastic waste, glass waste, molten slag waste, or metal waste. In the present invention, the particulate excrement disposal material has a non-water-absorbing smooth surface, that is, a non-water-absorbing or poorly water-absorbing, so that urine and feces attached thereto can be easily washed away by washing with water or a disinfectant. It is preferable to use granules having a smooth surface.

Examples of such a granular material having no water absorption or having a smooth surface with poor water absorption include granules made of a plastic material, granules made of a glass material, and granules made of ceramics obtained by heat treatment. And granulated material of molten slag or stainless steel, or granular material of plastic waste material, granular material of glass waste material, granular material of pottery waste material, granular material of molten slag waste material or granular material of stainless steel waste material, and the like. However, even if it is a granular material made of a porous material, the granular excrement disposal material of the present invention is obtained by surface processing or by coating the surface with a plastic material film or the like to make it a non-water-absorbing surface. be able to. Examples of the granular core material which is subjected to such surface treatment or coating treatment to be a non-water-absorbing granular excrement disposal material include, for example, granules made of unglazed material, porcelain granules, silica gel granules, and alumina granules. And porous granules such as calcined granules of inorganic materials.

As the granular core member which is subjected to a surface treatment, a water repellent treatment, or a coating treatment such as plastic to be a non-water-absorbing granular excrement disposal material, a granular material made of plastic material or plastic waste material, a glass material or There are granules made of glass waste material, granules made of pottery or waste ceramics, granules of molten slag, and granules made of stainless steel or stainless steel waste material.

In the present invention, the non-water-absorbing particulate excrement disposal material is used by being disposed in a conventional animal box-type toilet. In the box-shaped toilet of the present invention, an opening for discharging the particulate excrement disposal material is formed in a part of the side wall. When the granular excrement disposal material is arranged, the opening of the side wall portion is such that the particulate excrement disposal material is stored in the toilet.
An opening / closing member such as an opening / closing door or a sliding door is provided so as to be able to open and close. In the box-type toilet of the present invention, the upper and lower parts are separated via the perforated plate member, so that the excretion part is formed above and the sewage storage part can be formed below.

In the present invention, the perforated plate member has a gap or a hole through which sewage including feces, urine, and washing water can pass. Such porous members include
There are a perforated plate or a net, and for example, a tray made of a saw blade, a perforated plate or a mesh member can be used.
In this case, after use, the dirty particulate excrement disposal material can be cleaned by washing with water, and furthermore,
After washing, it may be dried by sun drying and put in the toilet, or even if it is put in the toilet immediately after washing, it can be easily dried and used repeatedly by the next use.

In the present invention, the non-water-absorbing granular excrement disposal material can be used, for example, by arranging it on water-absorbing paper. In this case, after use, the particulate excrement disposal material to which filth adheres is removed from the toilet. But,
In the case of urine, part of the excreted urine adheres to the non-water-absorbing granular excrement disposal material, and the remainder is absorbed by water-absorbing paper spread under the granular excrement disposal material. Therefore, the granular excrement disposal material may be washed and used each time, but may be used after being washed several times. In addition, since the urine that does not adhere to the granular excrement disposal material is absorbed by the absorbent paper, the amount of urine adhering to the absorbent paper during excretion is reduced by the amount attached to the particulate excrement disposal material. Is done. Therefore, the number of times the water-absorbing paper is used can be increased, and for example, the number of water-absorbing papers to be replaced per day can be reduced to a fraction of the number when the granular excrement disposal material is not used.

In the present invention, when the particulate excrement disposal material is directly disposed in the toilet, the bottom of the portion of the toilet into which the particulate excrement disposal material is to be placed is slightly inclined, for example, 3 ° or more, preferably Is preferably formed at an angle of 5 ° or more and 10 ° or less. As described above, when the bottom of the non-water-absorbing granular excrement disposal material is inclined at the location where the granular excrement disposal material is disposed, the outlet of the granular excrement disposal material is opened, so that the granular excrement disposal material is rolled and easily discharged from the excretion unit Can be discharged. Also, in this case, by forming the bottom of the discharge unit with a perforated plate member, excreta such as urine can be discharged from a room formed below the perforated plate member, for example, into a sewage storage unit such as a washed liquid storage unit. Can be separated. In this manner, when the bottom of the excretory part where the granular excrement disposal material is disposed is inclined and the surface of the bottom of the excretory part is water-repellent, the excretion part bottom becomes difficult to get wet with water, and along the inclination. Since the wastewater flows down, wastewater such as urine can be collected on the lower side, and the amount of wastewater such as urine adhering to the bottom of the toilet bowl can be reduced, which is preferable.

As described above, when the bottom of the place where the granular excrement disposal material is disposed is inclined, the interior of the toilet is accommodated with the portion for containing the particulate excrement disposal material, the excrement, the used washing drainage and the like. It is preferred that the sewage sump is divided via an intermediate partition member. In this case, if the intermediate partition member is formed of a perforated plate member such as a net, the portion for containing the particulate excrement disposal material communicates with the sewage reservoir through the intermediate partition member, so that the particulate excrement disposal material is placed in the toilet. Can be easily washed and dried as it is placed, so that it is not necessary to resupply the granular excrement disposal material in preparation for the next excretion, the toilet bowl is easy and easy to handle, and sanitary Can be used repeatedly. In addition, in this case, since the bottom of the portion for containing the granular excrement disposal material is formed of a perforated plate, attached urine and feces are washed away by washing water,
Since the wastewater is collected together with the washed wastewater in the wastewater sump at the bottom of the toilet bowl, it can be discharged to the sewage or the like from the wastewater sump, for example, several times.

In the toilet of the present invention, a scraper for scraping up the particulate excrement disposal material, for example, a scraper having comb-shaped teeth or a scraper having a scraping plate can be provided in the excretory part. In this case, a driving device and a guide member for guiding the scraper can be provided along the excretory portion side wall so that the scraper can be moved along the inclined surface.

According to the present invention, since the surface of the granular excrement disposal material is formed non-water-absorbing and smooth, the granular excrement-treating material to which excrement adheres can be used in a toilet bowl. Alternatively, it is easy to wash out the excrement that adheres to the non-water-absorbing particulate excrement disposal material by washing it with washing water outside the toilet. In addition, since the amount of washing water adhering to the non-water-absorbing granular excrement disposal material from which excrement is separated is extremely small, it is possible to dry the room indoors, and it is possible to keep it in the toilet in a relatively short time. Can be dried. And, after excretion, the sewage and filth adhering to the granular excrement disposal material are separated and discharged to the sewage sump by washing, so that the toilet can be used repeatedly, which is hygienic and after use. It does not bother with the treatment of the granular excrement disposal material.
